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!
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!
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!
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!
Action #4 – PoundPound the center of Marvin’s
body.Observations: What force(s)
are you applying to Marvin and how is it changing his appearance?
OUCH!
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!
Action #6 – Amputate and BoilAmputate (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!!!

What isn’t chemistry?Why should I care about physical and chemical changes in my everyday life?Where does matter come from and where does it go to if it can’t be created or destroyed?How would scientists predict the properties of a new element & where would it fit on the Periodic Table?What do I have in common with pencil graphite and diamonds?What would the biosphere be like without the 8 common elements in contains?
understanding that all matter in the universe is made up of elements
