SIMPLE MACHINE PROJECT

FOR MY PROJECT, I BUILT A CATAPULT.

MATERIALS I USED:

• popsicle sticks (skinny and regular)
• three rubber bands
• cardboard
• Elmer's glue and hot glue

FIRST STEP

• The first thing I did was place four popsicles side by side.
• Then I connected them together by glueing smaller popsicles on the bottom.
• This created the base for my catapult.

SECOND STEP

• Next, I glued the end of two skinny popsicle sticks together.
• This made it look like part of a triangle.

THIRD STEP

• Then I glued a long popsicle stick onto the side of the "triangle"
• (I repeated step two and three again.)

FOURTH STEP

FIFTH STEP

• Then I glued a round piece of cardboard at the top of the catapult.

SIXTH STEP

• I put a popsicle stick on the cardboard and held the end down by a ruber band.
