  1. Earth

    Build your own seismograph with this science activity

    By recording earthquakes, seismographs help scientists better understand and hopefully predict quakes.

  2. Earth

    Experiment: How does the tilt of Earth’s axis affect the seasons?

    Seasons have nothing to do with Earth’s distance from the sun. The real reason for the seasons is the tilt of Earth’s axis.

  3. Earth

    Experiment: Weather and climate in your neighborhood

    In this experiment, use historical weather data to investigate how weather and climate conditions have changed in your area over time.

  4. Physics

    Why are skis so long?

    Let’s strap skis to an action figure to see how long sticks of wood help people glide gracefully over snow.

  5. Plants

    Unlock pinecone secrets with this science activity

    Let’s find out how pinecones respond to different temperatures — by mimicking changes in weather from the comfort of our own kitchens!

  6. Chemistry

    Uncover leaves’ hidden colors in this science activity

    Let’s use a technique called paper chromatography to separate the pigments lurking in tree leaves.

  7. Math

    Experiment: M&M’S geometry

    The amount of candy in an M&M’S bag is never enough, but just how much is it? Let’s find out which geometric formula gives the best estimate.

  8. Microbes

    Experiment: Yeasty beasties

    It’s hard to believe a packet of dry yeast is full of living things. But feed the yeast the right things, and presto! You’ve got bubbly, oozing mess of life.

  9. Chemistry

    Experiment: Blow the best homemade bubbles

    What’s the best recipe for blowing the most impressive bubbles? Let’s find out.

  10. Tech

    Experiment: Make the fastest rubber band paddleboat

    With a rubber band and some cardboard, you can build your own paddleboat to speed across the surface of a pool.

  11. Materials Science

    Experiment: How much water is needed to cook pasta?

    In this cooking experiment, let’s find out if we can save time, energy and resources by boiling noodles in less water.

  12. Chemistry

    Experiment: How to keep fruit slices fresh

    Let’s explore why fruit tends to brown over time and how to keep it looking fresh.
