The Siemens Science Day website offers a variety of tools and resources that will help you reinvent science class. You'll find new, original hands-on activities and supporting videos, a teacher support center with best practice guides, monthly themes and an Ultimate Cool School sweepstakes.

Hands-On Science Activities and Videos

Clean up oil spills. Make slime. Create sand dunes. Leap into learning like never before.

Here you will find a wealth of Earth Science-related activities that will bolster your students' understanding of the atmosphere, oceans and biosphere, as well as the solid earth. Students will form sand dunes, simulate rock erosion, and create weather stations. View Earth Science Activities

This Month's Activity Theme

Monthly Theme
New Activites
  • Activate Wind Power
    Difficulty: 3

    In this activity, students will create their own windmills and test them in a wind created by a fan.

  • As Far As I Can Sea
    Difficulty: 3

    In this activity, students will learn the different techniques used to map the ocean, and will practice using those techniques themselves in the classroom.

  • Clean Class
    Difficulty: 1

    In this activity, students will observe different areas of the classroom and make predictions about which areas have the smallest and largest amount of germs. They will then observe pre-made samples of colonies of microorganisms from the different locations in the classroom.

  • It's Melting!
    Difficulty: 3

    In this activity, students will observe how ice melts on wood and metal blocks, and they will draw conclusions about how heat conducts through different materials.

  • Layers of Earth
    Difficulty: 4

    In this activity, students will work with a model that shows several layers of different rock types. They will then use simple tools to sample the layers and take a simple core sample from the model.

  • Oh The Tension
    Difficulty: 2

    In this activity, students carefully add drops of liquids to the surface of a penny to help them understand the concept of surface tension.

  • Shaky Ground
    Difficulty: 4

    In this activity, students will design a bridge or a building and observe how it performs in a simulated earthquake. Then, they will revise their designs to make them stronger and perform the simulation again.

  • Too Rotten for Me
    Difficulty: 2

    In this activity, students will observe foods that have been placed in different environments and compare the rates at which those foods decompose.

  • Watching Weather
    Difficulty: 3

    Students will make their own weather station consisting of actual and simplified versions of real weather equipment. They will use that equipment to make observations about the local weather.

  • What's for Lunch?
    Difficulty: 2

    In this activity, students will observe the behavior of ants in response to different concentrations of sugar water to make a conclusion about what food sources ants prefer.
