Hello Denigia! My name is Marlee Boyle. I am a 3rd-year pre-service teacher majoring in Elementary Education at Wartburg College in Waverly, Iowa. I have a wonderful and tasty idea you can do in your classroom to introduce solids and liquids!
I created a lesson a while back called 'Making Ice Cream with Science'. When I created it, I focused on endothermic and exothermic reactions, but you can easily turn this lesson on making homemade ice cream into a lesson about solids and liquids. It would focus on how the reaction of ice and salt can change the state of the ingredients from liquid to solid. Here is a wonderful link I found online that may help you. It is specifically tailored towards 2nd grade. https://aroundthekampfire.com/2020/01/ice-cream-bag-changing-matter-experiment-second-grade.html
Some tips and tricks: You may need gloves or towels for this activity. It gets quite cold. And, you can find dairy substitutes if students are lactose intolerant. Hope this helps!
