Question 1

Why do we not fall over when walking?

Accepted Answer

When we walk, our brain helps us balance, using tiny movements in our feet and body. It's like riding a bike, where you keep steady by adjusting your position.

Question 2

Why do balls bounce?

Accepted Answer

Balls bounce because when they hit the ground, they squash a little and then spring back to their shape, pushing them back up. It's like when you press down on a spring and then let it go!

Question 3

How does a swing move back and forth?

Accepted Answer

A swing moves because when you push off the ground, you start moving, and gravity pulls you back down. Each swing gets a little shorter unless you keep pushing.

Question 4

Why do we slide down slides?

Accepted Answer

We slide down slides because of gravity pulling us toward the ground and the smooth slide reduces friction. It's like how a sled glides easily on ice.

Question 5

How do bicycles move forward?

Accepted Answer

Bicycles move forward when you pedal, making the wheels turn. The wheels push against the ground, and that moves the bike forward.

Question 6

Why is it hard to stop a moving car?

Accepted Answer

A moving car is heavy and has a lot of energy, so it doesn’t stop right away. The brakes help by creating friction to slow it down.

Question 7

How do airplanes fly?

Accepted Answer

Airplanes fly because of the wings, which are shaped to lift the plane when air flows over and under them. This lift is stronger than gravity, so the plane stays in the air.

Question 8

Why do ice skaters spin so fast?

Accepted Answer

Ice skaters spin fast by pulling their arms close to their bodies, which makes them spin quicker. It's like when you pull in your legs on a spinning chair to go faster.

Question 9

How does a yo-yo come back up?

Accepted Answer

A yo-yo comes back up because when you throw it down, it spins and winds the string back up. This spinning gives it enough energy to return to your hand.

Question 10

How do boats float on water?

Accepted Answer

Boats float because they are shaped to push water aside and stay on top. Even though they’re heavy, the water supports them as long as they don’t take in water.

Question 11

Why do balloons rise in the air?

Accepted Answer

Balloons rise because they are filled with a gas, like helium, that is lighter than air. This makes them float up to the sky, just like a bubble in water.

Question 12

How do magnets stick to the fridge?

Accepted Answer

Magnets stick to the fridge because they have an invisible force that pulls on certain metals. This force makes the magnet hold tightly to the metal door.

Question 13

Why do we feel warm when we rub our hands together?

Accepted Answer

We feel warm when rubbing our hands because it creates friction. Friction generates heat, so your hands warm up like when you rub sticks together to make fire.

Question 14

How does a trampoline make us jump high?

Accepted Answer

A trampoline makes us jump high because it stretches and then quickly bounces back, pushing us upward with extra force. It's like getting a super bounce!

Question 15

Why do leaves fall from trees?

Accepted Answer

Leaves fall because gravity pulls them down when they detach from the tree. The wind can make them float a bit before they land.

Question 16

Why does a rubber band snap back when stretched?

Accepted Answer

A rubber band snaps back because it's made of stretchy material that wants to return to its original shape. When you let go, it quickly goes back.

Question 17

How do parachutes work?

Accepted Answer

Parachutes work by spreading out and catching a lot of air, which slows down a person's fall. It’s like a big air-breaker that gently lowers you down.

Question 18

Why does ice melt in our hands?

Accepted Answer

Ice melts in our hands because our hands are warm, and the heat helps turn the ice into water. The same thing happens when ice is left out in the sun.

Question 19

How do birds fly?

Accepted Answer

Birds fly by flapping their wings, which creates lift and pushes them forward. The wings slice through the air, helping them rise and glide.

Question 20

Why do we jump higher on a bed than on the floor?

Accepted Answer

We jump higher on a bed because the mattress pushes back when we push down. This force makes us bounce back up, just like on a trampoline.
