Students will build a model using littleBits to describe the different states of matter.

**Duration:** 1 class period (60 minutes)

**GRADE LEVEL**

Middle School (ages 11-13)

Elementary (ages 8-10)

**DIFFICULTY**

Beginner

**SUBJECT**

Physical Science

**MODULES & ACCESSORIES USED (3)**

dimmer (1)

power (1)

vibration motor (1)

**LESSON GUIDE**

**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?”
