Investigating Forces in a Circus: A Hands-On Lab Experience

DESCRIPTION

In this engaging lab activity, students will explore the concept of forces using circus-themed experiments. Participants will engage in activities such as Tug of War, Plate Spinning, Tightrope Walking, and Hula Hooping to investigate the balance of forces. Each activity involves data recording, diagrams, and analysis of balanced vs unbalanced forces. Students will document their findings and reflect on how forces impact performance. By the end of this lab, they will gain a clearer understanding of forces and their implications in real-world scenarios.

Presentation Transcript

  1. 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.

  2. Activities • Tug Lean of War • Plate spinning • Tight rope walking • Hula hooping

  3. In your notebook…. • 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

  4. 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) • Who had the advantage? Why? • How do you make it balanced?

  5. 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.

  6. Tight rope walking Write down the TIME it takes walking WITHOUT FALLING in the following ways: a) with your arms tight by your side (no diagram) 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?

  7. 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?

  8. 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.
