8.5(E) investigate how evidence of chemical
reactions indicate that new substances with

Objective: Identify examples of chemical and
physical changes.
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.
This sounds
fun!
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.
Action #1 = Pull
1. Pull the left arm of
Marvin.
Pull my arm!
2. Observations:
Describe what
happens when you
pull the marshmallow
arm of Marvin.
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?
Chomp
***REMEMBER: Only
record observations
about your CHEWING,
not swallowing.
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 – 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
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 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!!!
