ROLLING FEET!

Slow down there, speedster, there’s another set of feet on the move! Create your own pair of rolling feet and see who’s the fastest kid around.

Materials

• Paper
• Pencil
• Scissors
• Glue
• Thin cardboard (from a cereal box, for example)
• Packing tape
• Straws (wide and thin)

Directions

• Place one foot on your piece of paper. Use the pencil to trace around it.
• Repeat this process with your other foot. Use a second piece of paper if necessary.
• Use the scissors to cut both of your feet out.
• Use the scissors to help you disassemble your cardboard box. Lay it out and apply glue so that you can stick both of your cut-out feet on the cardboard. Use the scissors to cut them out once again.
• Take one thick straw and tape it to the inside of your roll of tape, so that the long end is pointing outward. Take your second thick straw and tape it directly across from your first, so that it is pointing outward in the opposite direction (you should have one straw sticking out to the right, and one sticking out to the left!).
• Use the scissors to trim your straws. You want them to stick out about 1 ½ inches from the edge of your roll of tape.
• Take your two thinner straws. Tape your right foot on top of one of them, and your left foot on top of the other. Place each of these straws inside the thicker straws.
• Trim off any excess part of the thinner straws that push out of the other side.
• Push your roll of tape forward and watch your feet go for a walk!

Spark Creative Learning!

• How are these feet able to move forward? Force! By applying force to the roll of tape, you cause it to move. Experiment to determine different ways you can apply force to the roll of tape. Are there any tools you can use to help you out?

• Watch those feet go! Create multiple pairs of feet with your family members and see whose can move the fastest.

• How far can you travel? Use a measuring tape to track how far you can make your feet go with one push.
