List 3 things that magnets will stick to

The whiteboard, paper clips, metal on a clipboard, some fridges, another magnet

100

How can you change the shape of a rock?

You can throw it to break it

100

What are 2 safety features cars have?

Seat belts and air bags

100

What is an example of a natural force?

Wind, hurricane, tornado, earthquake, land slide, soil erosion

100

Which type of force brings something closer to you? (push or pull)

Pull brings something closer to you. Pushing makes things further away.
200

What is an example of high friction (rough)?

Rubber tires on the road, running on the sidewalk

200

How can you change the direction of a ball that was thrown towards you?

You can hit it with a baseball bat, you can catch it and throw it in another direction, you can kick it

200

What are safety features that roller coasters have?

seat belts, head rests, safety bars

200

Why is soil erosion bad for the environment?

It causes pollution in rivers and oceans, farmers cannot grow their crops without soil

200

What does it mean when magnets "attract" and "repel"?

Attract means that the magnet sticks to something and repel means that they do not stick or attach.

300

What is an example of low (slippery) friction?

Wearing socks on tiles, going down a slide, walking on ice

300

How can you make something go faster?

Kick it with a lot of force, push it down a slide, make less friction (add water to make a slide slippery)

300

Why should you wear a seat belt in a car?

Because it keeps you safe in your seat, especially in case of an accident.

300

What is a landslide?

A landslide is a natural force. It happens when rock and mud fall down from a steep slope. A landslide can harm people and damage homes.

300

What are 3 ways you used forces today?

Pull open a door, pull your dogs leash when going on a walk, push in your chair, pull a book off a shelf, used a magnet to stick something to the fridge

400

What is an example of static electricity?

Static in laundry, lighting, rubbing a balloon on your head

400

How can you stop a helium balloon from floating up?

Pull the string down, pop the balloon 

400

Why do roller coasters have safety features?

Because they go very fast and sometimes upside down. You could fall out of your seat or hit your head.

400

What is soil erosion?

Soil erosion is when wind and rain (water) move the top layer of soil. The soil then pollutes rivers and makes it harder for farmers to use the land.

400

List 4 types of forces

Static, magnetic, muscular, friction and gravity
500

What is the difference between contact and non-contact force? Give an example of each.

Contact force is when the two objects touch and non-contact force is when they do not touch. A contact force is when pushing open a door. A non-contact force is gravity.

500

How can forces make something go further apart?

When bowling, the ball hits the pins and spreads them out. When knocking over one domino, the rest fall over too.

500

What are 3 safety items you can wear to keep you safe when playing outside? (on a bike, playing sports, swimming)

A helmet, knee pads, elbow pads, mouth guard, life vest
500

How can humans prevent soil erosion?

Planting trees and plants, especially near rivers

500

Give an example of a muscular force, gravity and friction

Muscular: pushing a door open, pulling a balloon down

Gravity: a leaf falling from a tree, gravity keeps us on the ground

Friction: high friction would be a car on the road, low friction would be going down a water slide
