13. Making your Marshmallow Man 1. Insert a toothpick halfway into the flat side of one marshmallow to form the body. 2. Stick the second marshmallow on the remaining end of the toothpick. 3. Insert four toothpicks into opposite sides of the body to make his arms and legs. 4. Place a marshmallow on a toothpick and stick half of the toothpick in the body to make the head. This sounds fun!

14. Action #1 = Pull 1. Pull the left arm of Marvin. 2. Observations: Describe what happens when you pull the marshmallow arm of Marvin. Pull my arm!

15. Action #2 – Chew 1. Take off Marvin’s right arm and chew it. 2. Observations: What forces are you placing on the marshmallow as you chew? ***REMEMBER: Only record observations about your CHEWING, not swallowing. Chomp chomp!

16. Action #3 – Digest Take Marvin’s left leg and digest it. Observations: What is happening as you are digesting Marvin’s leg? I’m yummy!

17. Action #4 – Pound Pound the center of Marvin’s body. Observations: What force(s) are you applying to Marvin and how is it changing his appearance? OUCH !

18. Action #5 – Puncture Puncture a hole through Marvin’s head. Observations: What force(s) did you apply here and how did the marshmallow head react? But I already have three holes in my head!

19. Action #6 – Amputate and Boil Amputate (cut off) Marvin’s right leg and carefully place it in the boiling water. Observations: How does the boiling water change Marvin’s leg? It’s HOT in here!!!
