Discover STEM in your Backyard

Teacher- and kid-approved STEM activities you can do at home


STEM is all the rage these days, but if you haven’t been near a science classroom since 12th grade, teaching STEM to your kids might seem a bit daunting. That’s why we’ve created these simple activities guaranteed to transform any parent into a Science Superhero—no experience required.


Explore Space with a Telescope

Let the kids stay up past bedtime and create memories that will last a lifetime. These simple astronomy activities are great for even the youngest aspiring astronomers.

  1. Moon Chaser
    The Moon is an ideal object for new telescope users. It’s big, bright, and visible almost every night. Take your telescope outside and point it toward the Moon. Note its current phase—crescent, half, gibbous, or full—and whether it’s waxing or waning. You can even capture a photo of the Moon by aligning your smartphone camera over the telescope’s eyepiece or using a special adapter.

    After your initial Moon-gazing session, make sure to revisit Luna over the following days and weeks. Take more photos and note the changes you see from night to night.

  2. Planet Hunter
    Download a free planetarium app for your smartphone or tablet, like Celestron’s free SkyPortal app for iOS and Android. Take a look at the Tonight’s Best list to find out which planets will be visible. While you observe, you can listen to hundreds of audio descriptions to learn more about the most popular celestial objects. Create a checklist and work on viewing every planet in the Solar System over the course of one year. Make notes about your observations.

  3. Star Splitter
    Even the most modest telescope will be able to split the famous double stars. Mizar, the second star in the Big Dipper’s handle, has a small companion star called Alcor. Thousands of years ago, people used Mizar as an eyesight test—those who could split the double star with the naked eye were thought to have excellent vision.

    For a more colorful view, try Albireo, a double star in the constellation Cygnus. Find it in your telescope and you’ll see that this star is a double—composed of a bright yellow star (actually a binary star itself) and a brilliant blue companion star.

Want some extra help locating stars and planets? Our new StarSense Explorer telescopes work with a specialized smartphone app to guide you step by step. Simply place your phone in the dock, select an object to view, and follow the onscreen arrows to place it perfectly in the eyepiece.

Binoculars and Spotting Scopes

Let your little naturalist hit the local trails, a nearby nature preserve, or your own yard. A simple pair of binoculars and a field notebook will get them in a scientific state of mind.

  1. The Birds and the Bumblebees
    Bird watching is a favorite activity for young and old alike. Download a birding app like Merlin Bird ID by the Cornell Lab of Ornithology to learn about birds that are common in your area. Then, head outside to look for them. Keep track of how many birds of each species you can spot—and don’t forget to keep your ears open for bird songs, too. If there aren’t many birds out, try using the binoculars to view bumblebees and butterflies at closer distances.

  2. Scan the Sea (or Sky)
    If you live in a coastal area, the spring is a great time to go whale watching. Perch yourself on a high cliff and scan the water. You might see a whale’s fluke or spray from its blowhole. No ocean nearby? Find a spot with a view of your local airport and watch the planes take off and land.

  3. Eye Spy
    This favorite road trip game becomes a lot more fun when you and your future scientist are equipped with binoculars. Stake out a scenic locale and take turns finding targets to view through your optics.
