Hands On Labs & Lessons with Ward’s World Science

I remember walking with my new principal to my first classroom. She showed me to my room and then the book closet. “This is what we have for science! Feel free to use whatever’s in here!” With that, she told me to let her know if I needed anything and was off. 

I was so overwhelmed! Where do I start? How do I make this engaging for the middle schoolers walking into my classroom next week? How badly I wish I had a resource like Ward’s World all those years ago! 

Ward’s World hits the nail on the head by giving teachers a great balance between rock solid information and engaging classroom activities. Everything you need is right here without having to spend hours searching for content and even more time searching for or creating hands-on activities that make learning real. 

Making Science Relevant Right Now

How Vaccines Take A Big Shot Against Viruses is excellent! Check it out and read for yourself! Students reading this learn what a vaccine is and how it works with their immune system to prevent disease in language they understand. Bring learning to life with Ward’s World Science Take-Out® Pathogens, Antibodies, And Vaccines. Students actually create models to see how vaccines work for themselves. 

Getting kids to do is so critical to their learning. This Looks Like A Moon activity does just that, and again provides students with foundational information that helps them understand what happens as we see different moon phases. As I always look to increase my student’s content specific vocabulary, I love how words are introduced: easy and non-threatening for even the most hesitant learners. Understanding how moon phases work is an abstract concept for some students, but Modeling The Moon’s Motion helps them really see the Sun, Moon, and Earth relationship. This is one of the coolest models to bring moon phases to life, and it builds right into the Looks Like A Moon activity. 

Rainbow Respiration & Photosynthesis

If you teach photosynthesis and respiration, you need Ward’s World Green Glucose Production Kit. It is so cool. All the supplies you need for 15 lab groups to complete the experiment are in the kit. 

Photosynthesis and respiration are easy to talk about in a science class, but really hard for kids to grasp because they can’t see it. They have the opportunity to interact with the process with this kit! Whether the algae is in the process of photosynthesis or respiration determines how much CO2 the algae is releasing. When students add algae beads to the bicarbonate indicator, the pH of the liquid changes based on how much CO2 is released by the algae! 

Students do this by placing one vial under a light to start the process of photosynthesis and they wrap one vial in foil to block out light and start respiration. 

If you’re teaching this while you’re distance learning, do the experiment at home! Take a time lapse video and stop at certain intervals. Or take photos and add them to a digital presentation with an elapsed time underneath each photo. 

(Side note: it’s easy to share digital media with a wide audience. Make sure any digital activities you create with Ward’s World science content is shared with your classroom only!)

When you’re ready to do the lab with your class, you can make or buy algae beads through Ward’s World.

Get A Little Creative

With so many of us participating in distance learning right now, what and how we are teaching is different than what it may have looked like in the classroom. With a little bit of flexibility and creativity, you can still use Ward’s World to teach engaging lessons. 

The Looks Like A Moon activity says it requires cookies. Ask students to make their model out of cookies if they have them. Otherwise, you can ask them to create it out of household items. Or maybe you have them make a model out of recycled objects. Get creative! Have a show and tell on Google Chats (maybe for a little bit of extra credit… I know how hesitant some of them are). Or create a collaborative presentation with a slide for each student where they can add a photo of their model and explain the moon phases next to it. 

Take a look at The Periodic Table of Candy. It is a great in-class activity, but with a little tweaking, you can make it a great digital activity also! Find images of all those candies and create a presentation to share with students where they can drag and drop the images to organize them. Be sure there’s a space to explain why they organized the candy the way they did. Take a few of the most creative or thoughtful, copy those slides onto a separate presentation, and screen share as you discuss them in your Google Chat or digital class meeting. 

For The Bold

If you’re feeling like you’re up for a challenge, use Ward’s World activities to create video lessons. Trust me – when you have students absent for labs or activities next year, you’ll be so thankful you made these. 

A super simple example, again with an awesome article, is their Greenhouse Effect Activity. Record a simple video after your students have read the article so they can see the experiment and record data, creating their own conclusion.

Check out Ward’s World Science Take Out Kits! These are labs and activities are ready to use without needing extra lab supplies. Don’t forget to purchase the class set so you can actually use them in class next year with students! Use your webcam or cell phone to create digital experiments for your students.

Science Demonstrations in the Middle School Classroom

Middle School Science Demonstrations for high student engagement without the mess of a lab

I’m a hands on teacher. I want kids to do things instead of me telling them things. But if I’ve learned anything over the last few years, it’s that the power of science demonstrations is a pretty awesome thing. 

Science Demonstrations Are Captivating

Think of the moments you crave as a teacher – where students are completely engaged. They can’t take their eyes off of what is going on. They have huge smiles on their faces and ask so many questions. I find myself in those moments most during demonstrations. I forget how captivating science can be! 

pH Science demonstration for middle school can be engaging instead of a lab.

Teachers are told that kids need to be doing the work and manipulating the materials. What is the point if they aren’t directly interacting with it? Turns out, there is a time and place for demonstrations.

Kids are uniquely engaged while a demonstration is taking place. They feel suspense and excitement. They’re so curious. It’s a feeling that is rarely matched.

Check out three of my favorite demonstrations! 

pH Testing

First of all, did you know that red cabbage contains an enzyme that reacts with a substance to reveal its pH?? I didn’t either! Read about how to make it here if you’re interested, it’s a lot to explain! 

This lab was a must. I wanted my seventh graders to grasp the concept of pH. However, buying enough supplies for eight group in each of my five classes was not an option.

Acids and bases are tested for pH level in this science demonstration for middle school.

So instead of giving up, I did a demonstration. The supplies were laid out on the counter. We tested apple juice, vinegar, shampoo, glass cleaner and a few other things. Students came up to measure, pour, and stir. Acids turned red and bases turned blue. The kids were so excited. The ooohhs and aaahhhs I heard as we measured and poured were the best! Definitely a win!

Convection

I knew this was not going to go over well if I let the kids do it. No. Way. 

This demonstration super easy, but super cool! This is easy, because it doesn’t take a whole lot of time. The basic idea of convection is that hot material rises and cold material sinks. 

Collect four small, identical jars or beakers. Fill two small jars with hot water and two small jars with cold water. Add some food coloring to the hot and cold water to differentiate between them. 

This science demonstration for convection shows how hot and cold water transfer heat.
Make Predictions

Even middle school science students who have learned about convection think the two colors of water are going to mix in both demonstrations. Why wouldn’t it? Every other time they have added one color to another, they’ve mixed to create a new color. 

By placing the jar of cold water on top of the jar of hot water, convection occurs and the two colors mix uniformly. Students watch the convection currents mix the water and are completely captivated. They ALL want to know what is happening. 

When you place the jar of hot water on top of the jar of cold water, convection doesn’t happen! The cool water is already at the bottom and the hot water is already at the top. The colors do not mix. 

Students are completely mind blown. I hear about this demonstration in the hall for the rest of the day and at the next parent teacher conferences!

Half of their excitement was probably from me spilling water so many times, but oh well! I suggest using glass bottles if you try it! Plastic did not work so well. 

Density of Gasses

This one is fun! 

Carbon dioxide is more dense than air. But that means nothing to the student sitting in your class. If anything, it is going to be a fact they memorize with absolutely no understanding behind it. (PS… if you want to read about how to teach density, check this blog post out!)

Create CO2 Gas

First, get a clear bucket with deep edges and fill the bottom with water about an inch or so high. Drop some dry ice in the bottom. (Do not touch the dry ice with your bare hands! Remember your lab safety skills!)

Create CO2 gas with dry ice and water. Demonstrate that CO2 is more dense than air by blowing bubbles.

Next, let this settle a little bit. The process where it goes from a solid directly to carbon dioxide gas is called sublimation

(If you can’t or don’t want to deal with dry ice, put a layer of baking soda in the bottom and pour vinegar in it. The chemical reaction creates carbon dioxide gas. Just let the bubbles settle down before you continue with the next part.) 

Demonstrate!

You have a few options here. One, bubbles. Two, fire. 

Blow bubbles into the classroom. Students will notice that they sink to the ground. Next, blow bubbles into the bucket. They don’t float all the way down. The reason? They’re filled with air. Air is less dense than carbon dioxide. And while students can’t see the CO2 gas, it’s there keeping the bubble from landing in the water. 

Show middle school students how CO2 gas exists. Pour CO2 gas over candles and they will go out. This demonstration shows CO2 gas, even though we can't see it.

Light three small candles. Your students should know that fire needs oxygen to burn. Grab a pitcher and scoop some air out of the bucket. Not the liquid at the bottom the CO2. You’re students will look at you like you’re crazy!

When you ask them what’s in the pitcher, they’ll likely say nothing or air. Actually, carbon dioxide gas is in the pitcher. Slowly pour it over the flame. 

The candles will burn out. Why? The CO2 gas is more dense than air and stays in the pitcher until you pour it out. Student’s can’t see this because, well, it’s a gas. But they can see the evidence of the gas when the flame goes out. 

Make It Even Better

If you’re up for it, find a paper towel roll, cut it in half long-ways and tape the ends together. You’ll have a long half pipe shape. Do the same demonstration, but prop one end of the paper towel roll up on a stack of books.

Light the candles, be careful, and place in a horizontal row with the paper towel roll, but not too close. When you pour the CO2 at the top of the ramp, the candles will go out one at a time. 

This demonstration is so exciting! Chances are, they’ve never seen something like it.  Best of all, it illustrates a concept that is so hard for students to grasp!

Let Them Participate

Engage them. Let them pour, or cut, or measure. Ask questions. Have a conversation with them as you are presenting your demonstration. This is what makes science come alive to your students! 

It is totally possible to be engaging, exciting, and authentic without handing the reins completely over to your students. Every day is different. Every topic is different. Use your judgement on when to do a lab or a demonstration. 

Tell me your favorite science demonstrations in the comment section! I want to know what you use in your classroom!

Science demonstrations are highly engaging for students. Middle school science is so exciting. Engage your students by showing simple demonstrations in class instead of setting up a complex lab!

The Perfect Chemical Change Lab for Middle School Students

Have you ever accidentally dropped bleach on a shirt? It’s ruined. Completely and totally. What I never realized was a chemical change is created between the dye in the shirt and the bleach.

I was overwhelmed the first time I taught middle school chemistry.

The supplies I thought I needed seemed so complicated. In reality, chemical changes occur all around us. Teaching this became a matter of utilizing simple examples students encounter every day.

Lab Objectives

Teaching students how to identify a chemical change does not have to be hard. In fact, you can use this Chemical Change Lab to demonstrate a simple chemical change with a few items you can find in your science classroom (or kitchen)! 

I love using labs that have multiple objectives. More objectives means more diverse student learning. This Chemical Change Lab meets the following objectives: 

  • Lab safety procedures
  • Measuring liquids using the metric system
  • Identifying a chemical change
  • Using evidence from the lab to write a clear conclusion

(TIP: If you use notebooks, you can copy the answer pages at 80% and students can glue them into their notebooks.)

Completing the Lab

The lab itself is very easy. Students add vinegar, bleach, and hydrogen peroxide to three different test tubes filled with colored water and determine which one shows a chemical change. 

Give students a chance to write a hypothesis and explain their reasoning before the lab starts. I ask them to write this alone to encourage independent thinking. However, collaborating with peers to write a hypothesis is a great option too.

Be sure to tell them they’re not supposed to be right. That’s why we’re testing it!

This lab includes so many simple steps. All the students will have a chance to measure, pour, or swirl… they are so engaged! The test tube with bleach poured into it will show a chemical change. The water turns a lighter color than the water in the other test tubes. 

(If you need a simple way to group students for labs, check out my Grouping Cards on TPT. Read about how I use them here!)

After the lab, students write a conclusion explaining whether their hypothesis was correct or incorrect using evidence from the lab.

While this task may be simple, students get the opportunity to think critically and write about it. It’s also an easy check for me to see who needs some additional support!

Why It’s Perfect

The simplicity of this lab is perfect. While middle school chemistry can be intimidating, this lab is not. The explanation, execution, and clean up time easily fits into the 45 minute class period.The materials are easy to find, the steps are simple, and students are amazed to see how the bleach makes the color of the water lighter!

Using Grouping Cards in Your Classroom

If you’ve been a middle school teacher for more than a hot second, you know that those kids are social! They want to talk and work with friends! Every time I’m done giving directions, at least one student in every class asks, “Are we going to work in groups?” Ultimately, I have to orchestrate group work and it can be either really easy or really difficult.  

Two Bad Options

Option 1: Easy. Kids make their own groups. This is too lenient for how I run my classroom and leads to goofy behaviors or students feeling left out of peer groups. Occasionally, it’s totally fine.

Option 2: Complicated. I go through each class and put groups of kids together. This is so time-consuming because I’m thinking I know for sure these two kids can’t work together… and this kid and this kid are best friends…. and this kid is always working when he’s next to this kid but not next to this kid. So this becomes a huge a jumbled puzzle that takes me some time to figure out. Or I can create an account on some website and type (ugh) in all the kids names for all my classes. The problem occurs when kids are absent or their schedule changes and they’re not in first hour anymore – and really, who has time to remember to move the kid’s name on the grouping website… what was my login to that anyway?!

The Solution

Enter grouping cards.

I LOVE THESE. I will never teach a day without them again. Here’s how it works. Each student gets one card. The card has one letter, one color, and one number. (I also have each of my lab tables labeled with each color, letter, and number so they know where to go once they are placed in groups.) They can be put into one of three different groups: 

  1. Their number. When I tell the students to go into groups with their number, all the ones go to table one all the twos go to table to all the threes go to table 3 and so on.
  2. Their color. If I tell them to go to their colors, the pinks will go to the pink table, the oranges go to the orange table… and so on. 
  3. Their letter.  I feel like you get it by now.

No Planning Ahead

The number of students in a class does not matter even one bit. If three kids are absent or one gets their schedule changed, it won’t impact how I use the grouping cards. Take out a set of colors or numbers, and add WILD cards if you need to – I’ll get to those in a second! 

After I pass out the cards, I’ll call out which group I want them to go to. Of course, this is the last thing I say because after that, they won’t hear a word – they’re so anxious to get going!

This is where the magic happens. Let’s say I told them to go to their letters. Against all odds, that group of four boys that cannot stop giggling ended up together. I can quickly say, “Never mind! Go to your color!” and I know all four of those boys will be separated, because none of the cards have the same color, letter or number. If they do end up in the same group, I know they’re cheating!

I LOVE this strategy because it’s easy to do on the fly and it is so flexible. Because sometimes you don’t plan for things and groups just suddenly need to happen. Or I don’t want to spend my night making groups.

The Wild Card

The WILD Card was born from a year when I had a class of 38 seventh graders! I only had 8 lab tables, which meant I always had to make a few groups of five. The WILD Card says, “Choose a group, as long as you make the fifth member!” Because they are shuffled into the deck, different kids got them every time and were so excited to get to choose. When I didn’t need them, I took them out. Easy as that.

While I mostly use these for group work, sometimes I need to get the kids to get out of their normal rut. Occasionally I will let them work with their numbers for eight minutes, with their colors for eight minutes and then with their letters for eight minutes. So over the course of the class, they get to work with 11 other people on the same assignment but they didn’t work with friends the whole time.

I will say it again. This is the best classroom management tool I have ever used. The structure moves kids efficiently, but the flexibility to change things up is perfect for a classroom. Grouping cards are a LIFESAVER for any teacher!

Quick disclaimer, especially for new teachers. While these card will help your classroom management, introducing these cards will require you to model like crazy. Kids need to know that there is a specific procedure for how to use these. When you pass them out the first time, explain how to use them. Have all the twos raise their hand and then have everyone point to where the twos go. Repeat this with all the blues or all the As. Randomly call out a few groups before you decide on letters, numbers, or colors. Students will start to get the idea.

Does Mint Really Make Your Mouth Cold?

Mint Lab

You know those days you dread as a teacher… the ones where you have a pep assembly or a bus evacuation practice that messes up your schedule so that you only see some of your classes, but not all of them. Teaching middle school science makes it even worse… you either have to fill a day or have a class or two behind until who knows when. 

I had that day. I had been dreading it all week because the weird schedule can be so hard to come back from. My 7th graders were learning the difference between qualitative and quantitative data. I wanted to give them something they could do to practice this skill without killing a day.

That’s when I came up with the idea for the Mint Lab. The Mint Lab answers the question, “Does mint really make your mouth cold?”
