Gravity Pulls Everything the Same Way

🧪Lab Brief #5

Simple Electricity.

🎯 Your mission

Set it up. Test it. Be amazed.

⚡ The twist

Energy never disappears — it just hides somewhere else.

🤯

Mind = Blown

🎢 You feel weightless on a roller coaster because you and the seat are falling at the same speed.

🔮

Make a hypothesis first

Before you start: which will move faster, and why?

Safety First

Have an adult check your set-up before you start, and tidy everything away afterwards.

Steps

Step 1 — Read

Read the explanation above and note the two key terms before you start.

Step 2 — Do

Drop objects while standing on opposite sides of a globe model and mark the direction each falls. Explain why people on both sides feel that they are the right way up.

Step 3 — Observe

Record what actually happened, including anything that did not match what you expected.

Step 4 — Record

Write a conclusion that answers the question this lesson opened with, and state your uncertainty.
