How do parking garages stack so many cars?

Video · 1:48 · Crafty Clover explains, from A Million Whys Book 25

A parking garage stacks many levels of flat floors, connected by ramps, so many cars can fit in a small footprint. Ramps may spiral or run back and forth. Sensors above each space can detect whether a car is there and light up green or red, guiding drivers to open spots. Walls and ceilings are strong concrete. Take care to stay near the adults in garages.

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How do parking garages stack so many cars?

The Big Idea

Cities have lots of cars and not much space. Parking garages stack cars on top of each other! Let's see how.

Many Levels

Step one: Many Levels. A parking garage stacks many levels of flat floors. That way, many cars fit in a small footprint, which matters in a crowded city.

Ramps

Step two: Ramps. Ramps connect the levels. They may spiral or run back and forth.

Sensors

Step three: Sensors. Sensors above each space can detect whether a car is there and light up green or red. They guide drivers to open spots. Stay close to your grown-ups in garages.

A Closer Look

Let's take a closer look! Ramps connect floors. Spaces hold cars. Sensors show open spots. Concrete holds it all.

Quick Facts

Quick facts! Some automated garages park cars using robot lifts. Stay close to grown-ups in garages. Lights help you see. Floors have numbers or colors.

Think Like a Scientist

Now, think like a scientist! Draw a three-level parking garage. Add ramps between the levels. Use arrows to show how cars move. Draw parking spaces. Color the open spots green.

Outro

Parking garages stack many flat floors connected by ramps, fitting lots of cars in a small space. Sensors light up green or red to guide drivers to open spots. Science is amazing! Keep wondering and keep exploring! Share what you learned with someone at home, and see what they think! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books.
