Inclined Planes and Ramps

🧪Lab Brief #2

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?

What You'll Learn

An inclined plane is a flat, slanted surface, like a ramp, that makes lifting easier. Pushing a load up a gentle slope takes less force than lifting it straight up, though you must move it a longer distance.

Key Words

Tap a word to see its definition.

Materials Needed

weights
spring scale

Safety First

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

Steps

Step 1 — Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 — Do

Test friction: pull a weighted box across 4 surfaces (carpet, tile, sandpaper, foil). Use a spring scale to measure the force needed for each.

Step 3 — Observe

Note any unexpected results and think about why they happened.

Step 4 — Record

Share your findings with the class or a partner and discuss what you learned.

Question 1

1 of 3

Which simple machine is a ramp?

How sure are you going to be?😐 maybe

🌍

Where you see this in real life

This is why airplanes can fly and why rockets reach space.

🏆

Stretch Challenge

Try this in real life this week.

This week, find one thing in your house that turns one kind of energy into another.

👨‍👩‍👧

For the dinner table

“Show me something at home that uses this kind of energy.”
