  2. Problem: Can a coffee can be used to create energy? Hypothesis: If rubber bands, a coffee can with 2 lids, a bead and pencils are used, then the racer will _____________. Materials: 1 coffee can, 2 coffee can lids, rubber bands, scissors, beads, paper clip, pencils.

  3. Procedure: Remove the bottom portion of the coffee can with a can opener. 2. Punch a hole into the middle of each of the plastic lids with the scissors. Hook a large paper clip onto the rubber band. 3. Push the rubber band through the hole on one of the coffee can lids. Keep the paper clip attached to the rubber band on the outside of the lid.

  4. 4. Tape the paper clip flat onto the lid to keep it from pulling through the hole. 5. Place the lid on one end of the coffee can. 6. Pull the rubber band through the coffee can and through the hole of the other lid. Set this second lid in place on the coffee can. 7. Push the rubber band through the hole in a bead. Slide the bead down the rubber band so it sits against the lid.

  5. 8. Pass a pencil through the loop in the rubber band on the opposite side of the bead. 9. Pass a pencil through the loop in the rubber band on the opposite side of the bead. 10. Adjust the pencil so one end sits flush against the edge of the coffee can lid and the opposite end extends beyond the lid. 11. Twist the pencil around the lid to wind the rubber band inside.

  6. 12. Set the coffee can on a flat surface, and release the pencil to send it rolling. Data: Conclusion: ____________________________________________________________________________________________________________________________________________________________
