Slide 16: The three forms of matter revisited/Discussion
I show slides 1-13 and discuss, then I do the observation. After the observation and clean up, I wrap up with slides 14-16.
Observation: You will need a small styrofoam plate and a drinking straw for each student, some Dawn dishwashing liquid, and some water. Also be prepared with paper towels for clean up/messes. I like to put a paper towel under each student's plate as well.
1) Give each student a plate.
2) Show the dishwashing liquid and ask if it is a solid, liquid or gas. After discussing how it's a liquid, squeeze about a dime-sized circle of it in the center of each child's plate.
3) Show the water and lead the children to discuss how it's also a liquid. Pour some water directly over the dishwashing liquid in each plate- just enough to cover the bottom of the whole plate.
4) Discuss how the drinking straws are solids, and give each child one. IMPORTANT: Warn students not to suck in through the straw. Have them practice blowing lightly (not sucking) into the air before having them do the next step.
5) Demonstrate how to put the straw straight down into the liquid and blow gently, which will create a "honeycomb" of bubbles =) Remind students to keep the end of the straw under water so they won't blow the liquid off the plate. Once the plate is full of bubbles, they can use the straw to pop them and start over.
This always brings up discussion about how the water and Dawn are liquids and how the bubbles are full of gas, but are the bubbles liquid or solid? It seems even "experts" can't even agree on this one!!
