Hey everyone, I'm Olga.

I’m a proud Latina Googler, and I work in our computer science education department.

In this activity (dun dun dun daa!), you're going to make your own Google logo.

Happy Earth Day!

Happy Earth Day!

Happy Earth Day to you!

Google often creates special logos, called “Google Doodles,” to celebrate important things like people, places, holidays, and Earth Day!

People all over the world observe Earth Day on April 22.

Earth Day is a time to celebrate the natural world and focus on ways to protect it.

Organizations like World Wildlife Fund protect the planet's animals and natural environment.

Plus, they use computer science and technology to do it!

Individuals like you can take steps to protect animals, reduce waste, and make others aware of ways to preserve the natural world.

The skills you will use in this activity are similar to what environmental organizations, like World Wildlife Fund, use in their efforts.

For example, sensors created by computer scientists are used to watch over animals and their habitats.

Today, you will code a logo about celebrating Yay!

and protecting the environment.

You might create an Earth Day logo that celebrates animals in their natural habitats, raises awareness of how waste and pollution impact the planet, or encourages people use alternative energy sources like wind and solar powered technology.

The best part is that it’s all up to you!

As you code, you will use computer science concepts that are used every day, like: Events Sequencing And Loops You'll make your logo using the Scratch website.

After watching this video, open the starter project linked on this page.

This will open Scratch in a new tab.

Scratch uses code blocks to give characters, called sprites, instructions, like “When a sprite is clicked, make it say something about itself.”

This project has six sprites you can program.

Each sprite has multiple costumes you can choose from.

Some sprites are animals, like the panda, sea turtle, and monarch butterfly caterpillar.

Other sprites encourage sustainability, which is living in balance with the natural world.

After opening your project, return to this tab to watch videos that will show you different ways to code your Earth Day logo, like how to make a letter bounce, speak, or disappear!

It's all up to you!

And watch as many videos as you like.

And here's a helpful trick.

While you work, pause a video to complete a step in your project.

Or better yet, rearrange your windows to show Scratch and a video at the same time.

Now it’s your turn!

Select and open the starter project.

Return to this tab, and select a video below.

Watch the video, and complete the steps in your project.

Then watch more videos to customize your Earth Day project.

Time to get coding!
