• What size of wheels on the mousetrap car make the mousetrap car go the and the farthest?

• I chose this “Big Question” because I thought it would be fun but yet difficult

Interesting facts from research

• The large wheels on the mousetrap car make the mousetrap car go the farthest.

Materials & Procedure• Materials:• 3 mousetraps. • Foam board.• String.• Wooden dowels.• 8 I inch wheels.• 2 inch ½ wheels.• coat hanger.• Rubber cement.• tape measure• Pins• sewing bobbins• plastic drinking straws

• Procedure:• Assemble 3 mouse trap cars ,

all with one inch wheels on the front . One with 1 inch back tires, one with 1 ½ inch tires , and one with 2 inch tire . line up each car on the starting line let go of the metal band. Run each car 5 times. Average each cars distance compare results to deter man which wheel size produced the farthest distance.

Control & Variables

• Control: 1 inch back tires

• Variables: 1 ½ back tires and another with 2 inch back tires
