FORCES CIRCUS

“Roll up roll up”……..

• You are going to carry out a lab to investigate the forces in a circus. You will carry out a number of activities and investigate which forces are involved and what happens if they are not balanced.
Activities
• Tug Lean of War
• Plate spinning
• Tight rope walking
• Hula hooping
• Activity title e.g. tug of war
• Record data / answer questions
• Diagrams using arrows to show the direction of the forces
• A sentence explaining the balanced and unbalanced forces involved in the activity
Tug Lean of war
• Boys vs. girls
• Taller vs shorter or Older vs. younger
• Equal random distribution of students

DRAW A DIAGRAM FOR EACH SCENARIO

Questions:

• What did you see with each set?
• (winner, time to win)
• How do you make it balanced?
Plate spinning

Spin the ball or a plate on the point of your finger or a pencil.

DRAW A DIAGRAM

Questions:

• How long can you do this for?
• What did you have to do to keep it spinning?
• Does it matter where you put the pencil? Explain.
Tight rope walking

Write down the TIME it takes walking WITHOUT FALLING in the following ways:

b) arms held out for balance (DIAGRAM)

c) carrying a heavy bag on one side (DIAGRAM)

Questions:

• What do you notice about the times?
• What did you do when you had the heavy bag?
• What affects the balance most?
Hula hooping

Part 1-with just one push and no moving- DIAGRAM

• What’s the most number you can spin?
• How long does the spin last?

Part 2- try to hula hoop like normal- DIAGRAM

• How many times can you spin the hoop in 1 min?
• How long can you make it spin for?
• What do you have to do to make it spin well?

In class:

• What force is involved in the hoop spinning?
• How do you balance it?
Conclusion
• In this lab you were looking at balanced and unbalanced forces.
• Write a paragraph explaining what you found out about ‘what a force is’ and what happens when they are balanced and unbalanced.
