![]() I can’t believe how long I avoided making slime. THE CHANGING STATES OF MATTER … SLIME TIME! When they can see it from the side, it’s so much easier to notice the details in the matter, especially in the gas bubbles. TINY TIP: Make sure you use clear cups so the children can observe and compare the contents. In this way, it makes this activity perfect for the beginning of the unit. Instead of talking about the changing states of matter, we just identify them. If left alone for a bit, the consistency of the ice cream and the root beer will change, but I don’t use this lesson in that way. In one single treat, kids can visibly observe all three states: a solid, a liquid, and a gas. On deck… more sweet science! This activity isn’t an experiment as much as it is a simple demonstration of the three different states of matter. ![]() For this reason, I love the opportunity it gives kids to go home and “teach” others. One thing I really like about these labs is that they’re easy (and fairly cheap) to repeat. ![]() This lab□comes with recording sheets and a nonfiction page explaining the chemical reaction. It’s one of our favorite labs for learning about the changing states of matter. This is something I routinely do if I don’t have time during science.īefore we start this next investigation, I ask… “How can we get this balloon inflated without blowing air into it?” Their ideas are pretty cute, but none of them have ever correctly hypothesized the baking soda-vinegar answer. Because of the nature of the work, you could plan this activity for your literacy block. It’s easy to prep, especially if you teach the kids how to do the folding and cutting themselves. The picture at the top of the post□shows the ice cream flip book. There’s an informational reading passage that explains the science behind the ice cream lab, as well as a flip book project that reflects their comprehension. Following the science lab, you can integrate reading and writing with a variety of connected activities that are also provided in the set. In this STATES OF MATTERteaching resource, I’ve included lab worksheets and step-by-step charts showing students how to make their own vanilla ice cream. And you might be surprised by how few ingredients you need: That’s literally a recipe for success.įor children who are learning about the changing states of matter, Baggie Ice Cream is a fun, kinesthetic way to show how matter can be changed by cold temperatures. I mean, how could it not? It’s cream, sugar, and vanilla. That being said, did you know you can make ice cream in a plastic bag? It’s one of those things you see on Pinterest and raise an eyebrow at, but it actually works. My now-grown daughter would add that her fourth grade teacher’s Munchie Math was her favorite math experience ever, and is apparently the only reason she understands fractions to this day. For example, frozen nitrogen will form both the liquid phase and the vapor phase when exposed to normal temperature and pressure.I think food makes most things better, even science. Multiple phase changes can occur at once. For example, if you view the sublimation of dry ice into carbon dioxide gas, the white vapor that is observed is mostly water that is condensing from water vapor in the air into fog droplets. Phase changes aren't always clear when observing a situation. Plasma most often forms from ionization of a gas, although if sufficient energy and enough space are available, it's presumably possible for a liquid or solid to ionize directly into a gas. Plasma: Plasma can recombine to form a gas. Gases form from the sublimation of solids, vaporization of liquids, and recombination of plasma. Gases: Gases can ionize into plasma, condense into liquids, or undergo deposition into solids. Liquids form by condensation of gases and melting of solids. Liquids: Liquids can vaporize into gases or freeze into solids. Solids form by deposition from gases or freezing of liquids. Solids: Solids can melt into liquids or sublime into gases. Another way to list phase changes is by states of matter:
