PROBLEM: How many different types of motion are there?

PREDICTION:

PROCEDURE:

Go to the appropriate stations and answer the questions below. Be careful not to break any of the toys.

YO-YO.

1. Can you make the yo-yo go up and down?
2. Watch each student in your group and describe the motion of their yo-yo. You can give more than 1 chance. Record your information below.

BALLOON. First, stretch out the balloon. Blow it up and hold onto the mouthpiece so no air escapes. Put a piece of thread through a one inch piece of straw. Then tape the straw to the balloon. Now tie one end of the string to a chair and hold the other end. Release the balloon and watch it move along the string. Try tilting the string upwards.

Describe the motion:

FORCE MACHINE. Pick up the amount of balls on the data chart and record what happens when you let the ball or balls go.

BALL. Toss a ball at least 3 meters into the air. Describe the motion.

ORBITER. Place your fingers in the handles. Wind the string up by flipping wrists in a circular motion. Pull hands out rapidly. Alternate outward and inward. Describe the motion.

GYROSCOPE. Hold the frame firmly in your hand. Thread the cord through the small hole near the top of the spindle. Turning the wheel carefully let the cord wind around the spindle from hole to hub and back again. Now pull the cord away from the gyroscope with a quick, strong motion. Describe the motion.

CONCLUSION: Describe the different motions you observed?
