Students will build a model using littleBits to describe the different states of matter.
Duration: 1 class period (60 minutes)
Middle School (ages 11-13)
Elementary (ages 8-10)
MODULES & ACCESSORIES USED (3)
vibration motor (1)
STEP 1 : Connect
Show youtube video of ice cream melting. You only need to show about a minute of the video. https://www.youtube.com/watch?v=zzH4BtGcmTs What happens to the atoms as the ice cream melts?
STEP 2 : Engage
Build model of solid, liquid, and gas. Using little bits. Have students explore how the speed changes the motion of the packing peanuts. I found that taping some of the packing peanuts to the vibration motor creates more motion instead of just dropping the vibration motor in the bucket/box.
STEP 3 : Teach
Speed of the molecules is what determines that state of matter. Solid – slow Liquid – medium Gas – Fast Have students complete worksheet, and draw along.
STEP 4 : Practice
Use model set up, and ask students to show you solid, liquid, gas. Use model set up. Change the speed, and ask students what each state represents.
STEP 5 : Close
Exit Ticket Pass out pieces of paper or have students turn in a half sheet of paper. Have students answer, “What determines the state of matter of a substance?”
