Earth Science is not just about rocks and minerals. It also includes topics such as space, weather, and learning about the oceans. Cover the big ideas of Earth Science for kids with our best Earth Science lesson ideas! Below you’ll find a variety of hands-on science activities that use simple materials. Plus, free printable information packs to get you started!

Earth Science For Kids

Kiddos at any grade level can explore Earth Science on various levels, from preschool, kindergarten, elementary to middle school.

Younger students can check out rocks with a magnifying glass, while older students can dive into learning about the atmosphere or climate issues.  Below you will find science projects that are a perfect addition to your earth science lesson planning!  

What’s a fun activity to start with? We always love the shaving cream rain cloud for preschoolers!

Another super simple activity is a water cycle in a bag! Or get playful with sand and a beach erosion activity for older kiddos!

What Is Earth Science?

Earth Science is the study of the earth, and everything that physically makes up the earth and its atmosphere. From the soil we walk on, to the air we breathe and the oceans we swim in… learning about Earth Science isn’t just for Earth Day activities!

While some aspects of Earth Science are related to biology, it’s important to note that biology deals with the living things on earth. This includes plant life cycles, food chains, animals, and more. Learn more about plants.

Fun Earth Science Questions to Ask

Kids are always curious about the world around them, especially since it feels so big and magical. Plus, they have many questions you can answer with easy-to-set-up earth science activities.

More fun questions to explore…

  • What makes a volcano erupt?
  • Where does rain come from?
  • Why does the beach get smaller or change shape?
  • What are fossils?
  • How does a tornado form?
  • Why causes an earthquake?

Why is the Sky Blue?

Ever wonder how to answer this question? Here’s the super simplest answer you can give your kiddos. Blue (and violet) light has the shortest wavelengths, so it more easily scatters when it hits the air molecules in the sky during the day. Other colors do not scatter as easily.

How To Set Up An Earth Science Project

Want to turn one of these fun earth science activities into a science project? Then you will want to check out these helpful resources.

Quick Toddler or Preschooler Earth Science

You don’t always have to set up an experiment for younger kiddos, especially when attention spans are short. Older pre-k kiddos may enjoy some fun ideas below but adjust your expectations. You really can introduce earth science topics without using worksheets or setting up complicated projects.

Hands-on Earth science activities you can do with young kids include:

  • Talk about the weather and mark sunny, cloudy, snowy, or rainy days on a paper calendar.
  • Talk about the water cycle and what happens when it rains.
  • Set up a rain gauge and check how much rainwater you collect after a storm.
  • Collect special rocks, and discuss what they look like.
  • Grab a magnifying glass and look at anything up close.
  • Lay on the ground and look up at the clouds.
  • Dig up a sensory soil bin and look through it (add some water).
  • Play in the sand and ocean at the beach.
  • Go for a nature walk and talk about the air, the clouds, and the ground.
