By the end of this lesson, students will have a better understanding of chemical reactions and the role matter plays in these processes. The combination of individual work, group collaboration, and hands-on learning aims to make the topic engaging and memorable.
"Good morning, class! Today, we are diving into the exciting world of chemical reactions and matter. Can anyone tell me what a chemical reaction is?"
[Wait for student responses.]
"Great! A chemical reaction is when substances combine or break apart to form new substances. Think about what happens when you bake a cake. You mix flour, sugar, eggs, and then, through heating, those ingredients change into something completely new! Understanding chemical reactions helps us to see the changes that occur in everything around us."
"Now, let's explore some key terms: reactants are the substances that start a reaction, and products are what we get at the end. We will look at different types of matter involved. Can anyone give me an example of a chemical reaction they've seen or heard about?"
[Encourage a few more student examples.]
"Now, I’m going to give each of you a card. These printable cards are for you to take notes on during today’s lesson. You'll want to jot down important points, observations, and any questions you have along the way."
[Distribute the cards and ensure every student has one.]
"Feel free to use your markers or pencils to personalize your cards! You will be using these for the next part of our lesson."
"Okay, let's move on to our next step. I would like you to turn to your neighbors and form groups of three. Once you’re in your groups, I’ll assign each group a specific type of chemical reaction to explore. The types you will be exploring are: combustion, synthesis, decomposition, and single replacement reactions."
[Give students a moment to form groups.]
"Once your groups are set, I’ll come around and tell you which type of reaction you will be investigating."
"Now it’s time for some hands-on learning! Each group will conduct a simple experiment based on the chemical reaction type you received. For example, if you're studying combustion, you might be looking at something that burns."
"Gather your supplies from the lab table that corresponds to your experiment. As you work, remember to observe closely and document how the reactants interact and what products appear. Use your cards to note down your observations."
[Start a timer for 25 minutes.]
"Remember to discuss within your group and make sure everyone is contributing to the observations!"
"Alright, everyone! You’ve been working hard. Let’s take a short break. I want you to stand up and do some quick stretching exercises. Let’s stretch our arms to the sky, touch our toes, and take a deep breath in and out. Feel free to shake out any tension."
[Lead students through a couple of minutes of guided stretching.]
"Okay, are we all feeling refreshed? Let’s head back to our seats!"
"Now that we’re all energized, let’s come together. Each group will take a few minutes to share their findings from the experiment. What did you observe? What changes did you watch happen? Which reactants did you start with, and what products were formed?"
[Give each group a moment to present their findings.]
"Great discussions, everyone! It’s wonderful to see how each reaction is unique."
"I would like to take a moment now to check the cards you’ve filled out. I’ll be collecting them from everyone to review later."
[Collect cards randomly or ask students to submit them in a designated area.]
"These cards will help me understand your learning from today. Feel free to ask your groups if you have any lingering questions before we continue."
"Let’s bring our lesson to a close. Today, we’ve learned about the fundamental concepts of chemical reactions and the characteristics of matter involved in those reactions. We conducted experiments, collaborated with our peers, and shared our observations."
"Before we end, does anyone have any final questions or thoughts they’d like to share?"
[Wait for any final questions.]
"Thank you all for your participation today! Remember, the world around us is full of chemical reactions—keep your eyes open for them in everyday life. Can’t wait to see you in our next lesson!"

Let's get up and move, it's time for a break,
With simple exercises, our bodies we'll awake.
First, we'll stretch our arms up high,
Reaching for the clouds, let our spirits fly.
Next, we touch our toes, bend and sway,
Feel the stretch in our legs, let's clear our day.
Now, let’s shake it out, our bodies we’ll free,
Wiggle our fingers, and jump like a bee!
March in place, let our hearts beat fast,
One, two, three—let's make this fun last!
Side to side, let's do a little twist,
Wave to our neighbors, we couldn’t resist!
Roll our shoulders back, then forward we go,
Round and round, feel the tension slow.
Finally, take a deep breath in and out,
With fresh air in our lungs, let’s give a shout!
"Learning is fun, we’re ready to explore!”
With our bodies awake, let’s learn even more!
