2. Lab Zone Activity: What happens when uneven forces act on an object? Activity: What happens when uneven forces act on an object?

3. Materials  Dot circle  Ring and screws  3 pieces of string  3 cups  3 paper clips  3 pipe cleaners  Dot circle  Ring and screws  3 pieces of string  3 cups  3 paper clips  3 pipe cleaners

4. What to Do…  Tie one end of each string around the ring.  Unbend 3 paper clips in a S form.  Tie one paper clip to each string  Place a dot sticker in the center of the table  Center the ring over the dot.  Tie one end of each string around the ring.  Unbend 3 paper clips in a S form.  Tie one paper clip to each string  Place a dot sticker in the center of the table  Center the ring over the dot.

5. What to Do…  Arrange the string so that they are equal distance apart from each other around the ring  Hang the strings over the edge of the table  Attach a pipe cleaner to each cup creating a handle.  Have one person in your group hold the ring in place  Then attach one cup to the paper clip on each string  Arrange the string so that they are equal distance apart from each other around the ring  Hang the strings over the edge of the table  Attach a pipe cleaner to each cup creating a handle.  Have one person in your group hold the ring in place  Then attach one cup to the paper clip on each string

6. What to do…  Adjust weights (screws) to the three cups until the ring in the center of the table stays centered over the dot  Keep adding and removing weights until the ring is balanced  Draw your set up, and record the number of weight in each cup  Adjust weights (screws) to the three cups until the ring in the center of the table stays centered over the dot  Keep adding and removing weights until the ring is balanced  Draw your set up, and record the number of weight in each cup

7. What to do…  When the ring is balanced move the strings to different positions.  Observe and record what happened to the ring.  Draw your set up, and record the number of weights in each cup  Again add weights until the ring is balanced record your new data.  When the ring is balanced move the strings to different positions.  Observe and record what happened to the ring.  Draw your set up, and record the number of weights in each cup  Again add weights until the ring is balanced record your new data.

8. Explain your results 1.What happened to the ring when you moved the string? 2.How did you balance it again? 3.Explain the results of this activity using the terns balanced forces and unbalanced forces. 1.What happened to the ring when you moved the string? 2.How did you balance it again? 3.Explain the results of this activity using the terns balanced forces and unbalanced forces.
