Question 1

Why do slides go fast?

Accepted Answer

Slides are designed to be smooth and sloped, so gravity can pull you down easily. The smoother the surface, the less friction slows you down.

Question 2

How do swings work?

Accepted Answer

Swings work using the force of a push and gravity to move back and forth. The chains or ropes let you swing in an arc, like you're drawing a big oval in the sky.

Question 3

Why do merry-go-rounds spin?

Accepted Answer

Merry-go-rounds spin because you push against the ground at an angle that makes it turn. The spinning keeps going because of momentum, which means things like to keep moving once they start.

Question 4

Why do seesaws balance in the middle?

Accepted Answer

A seesaw balances like a teeter-totter with a point called a fulcrum in the middle. When the weight is the same on both sides, the seesaw stays balanced.

Question 5

What makes the monkey bars stable?

Accepted Answer

Monkey bars are stable because they are built with strong materials and supported by posts buried in the ground. This makes them strong enough to hold your weight.

Question 6

Why is the ground under playgrounds often soft?

Accepted Answer

The ground is soft to help protect you if you fall. Materials like wood chips, rubber mats, or sand help absorb some of the impact.

Question 7

How do engineers decide where to put playground equipment?

Accepted Answer

Engineers look at the space and decide where equipment fits best so everyone can move around safely. They try to keep areas open for kids to run and play without bumping into things.

Question 8

Why are some playground slides bumpy or curvy?

Accepted Answer

Bumpy or curvy slides add fun by making you feel twists and turns. The curves slow you down a bit, making the ride more exciting and safe.

Question 9

Why are climbing walls different heights?

Accepted Answer

Climbing walls are different heights to give you a challenge as you get better at climbing. This way, there's always something new to try, whether you’re just starting or more experienced.

Question 10

Why is there space between the bars on the jungle gym?

Accepted Answer

Spaces between the bars are there so you can grab, swing, and climb around. They’re set at safe distances to make sure you won’t get stuck or hurt.

Question 11

Why do merry-go-rounds sometimes have handles?

Accepted Answer

Handles give you something to hold onto while spinning so you don't fall off. They help you feel more secure while you enjoy the ride.

Question 12

How does a zip line on a playground work?

Accepted Answer

A zip line works by letting you hang from a pulley that slides down a stretched wire. It uses gravity to pull you from the higher end to the lower end quickly.

Question 13

Why do some swings have seats with backs?

Accepted Answer

Swings with backs are designed for younger children to keep them safe. The backs help you stay in the seat without falling out easily.

Question 14

How do you stop on a swing?

Accepted Answer

To stop, you can drag your feet on the ground to slow down safely. You can also wait until you swing slower and use your legs to stop gently.

Question 15

What makes a teeter-totter go up and down?

Accepted Answer

A teeter-totter moves up and down because when one person pushes off the ground, gravity helps them go down while the other side goes up. It's like when two sides of a seesaw take turns!

Question 16

Why are slides sometimes made of metal and sometimes plastic?

Accepted Answer

Metal slides can be faster and are very durable, but they can get hot in the sun. Plastic slides are often cooler and can be made in more fun shapes and colors.

Question 17

How does gravity affect playground equipment?

Accepted Answer

Gravity pulls you down slides, swings, or any time you're in the air. It helps make activities fun by giving you speed and allowing you to feel weightless at times.

Question 18

Why do playgrounds have different textures on the ground?

Accepted Answer

Different textures like rubber mats or sand help keep you from slipping. They also provide a softer landing if you trip or fall.

Question 19

Why do play structures have roofs or shade?

Accepted Answer

Roofs or shade protect you from getting too hot or sunburned. They help keep the equipment cool so you can play comfortably.

Question 20

How do spring riders move?

Accepted Answer

Spring riders move when you rock back and forth. This works because a big spring under the seat lets you bounce up and down safely.
