This engaging lesson explores the three states of matter—solid, liquid, and gas—through a hands-on polymer experiment. Students hypothesize about combining two liquids and then mix glue, water, and Borax to create a unique material. The step-by-step procedure encourages observation and discussion, promoting scientific inquiry. After completing the experiment, students classify the resulting material and reflect on their learning. This interactive activity not only teaches about matter but also reinforces collaboration and critical thinking.

What makes a polymer? A lesson on the states of matter
Aim: Can you create a different state of matter by mixing two liquids together?
Yes or No • 1. What do you think? • Press Y for Yes. • Press N for No. • Choose your answer.
What are the three states of matter? • water, wood, and wind • liquid, solid, and gas • soda, pencil, and oxygen
Make a Hypothesis Now make a hypothesis based on this question with your partner: What will happen when the two mixtures are combined?
Now for the experiment!We will need the following materials:1. Borax2. Glue3. Water4. Popsicle Stick (for mixing)5. a bowl
Procedure, Step 1 (the directions, duh!) 1. Measure ¼ cup of water and ¼ cup of white glue. Now mix them together with the popsicle stick! • Now, discuss with your partner what you observe when mixing two liquids.
Step 2 2. Measure 1/3 cup of water and 3 tablespoons of Borax. Stir with the popsicle stick until the Borax dissolves. • Discuss with your partner what happened to the solid when it was mixed with the liquid.
Step 3 3. Next, pour the glue mixture into the Borax mixture. Stir the two mixtures together. • Discuss what you are observing with your partner.
Step 4 4. Remove the glue mixture from the bowl. Knead the glue mixture together for two minutes. Watch the clock!
Step 5 5. Observe the material. What state of matter would you classify the material as?
What state of matter would you classify the material as? • Gas • Liquid • Solid • All of the above
Record Your Observations • Pull out your science notebook. Record what you learned about the three states of matter.
