Engage and Amaze Your K-6 Students!

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
New Activites
  • How Healthy Is Your Ecosystem?
    Difficulty: 3
    NGSS

    In this activity, students will learn about the importance of balance in an ecosystem. They will simulate population changes over time. Then they will evaluate a local ecosystem and create a report that describes the ecosystem's health.

  • Before and After
    Difficulty: 1
    NGSS

    In this activity, students will evaluate different 'before' and 'after' stations to decide if heating and cooling changes are reversible. For example, cake batter vs. a cake that has been baked or melting and freezing water. Students will identify if heating or cooling the substance could reverse the change.

  • Chip Off the Old Block
    Difficulty: 1
    NGSS

    In this activity, students will identify specific physical traits of adult plants and animals that are passed on to their offspring. Students will examine images of young and mature plants and animals, and then match the adults to their offspring.

  • Why So Yummy?
    Difficulty: 1
    NGSS

    In this activity, students will investigate how tasty fruits help some plants survive. Students will dissect a variety of fruits and observe characteristics such as taste, type and number of seeds, size, shape, and protective coverings. They will use their observations to predict how fruits can help some plants survive and thrive in their environments.

  • Build This Structure
    Difficulty: 1
    NGSS

    Students will use provided materials to develop a structure that will withstand movement in Earth. A teacher will shake a table at a controlled rate for a specified timeframe. This will model a quick event on Earth compared to slower changes in Earth, such as the formation of the Grand Canyon. Students will use a rubric to evaluate different structure models.

  • Hiding in Plain Sight
    Difficulty: 2
    NGSS

    In this activity, students will investigate how camouflage can help an organism survive and reproduce in its environment. Students will design a camouflaged organism that can survive being 'eaten' by a predator. A simple predation simulation will be used to demonstrate how animals that blend into their environment are better suited to survive a predator on the hunt.

  • Ice Cores
    Difficulty: 1
    NGSS

    Students will evaluate water ice balloons to reconstruct recent climate history by sorting different layers of evidence.

  • Why is the Sky Blue?
    Difficulty: 1
    NGSS

    In this activity, students will use a glass jar, water, milk, and a flashlight to explain why the sky is blue. Students will scatter the light of a flashlight to discover why the sky is blue.

  • Water Slide
    Difficulty: 2
    NGSS

    In this activity, students will experiment with ice and water and evaluate how both can carry materials and change the formation of Earth's surface. About 71% of the Earth's surface is covered by water. Water exists on Earth in liquid, solid, and vapor states and shapes the land as it moves. In the Arctic and sub-Arctic, glacial erosion has shaped much of the landscape. Rivers and streams continually change the land it runs through all over the world.

  • How Can I Help?
    Difficulty: 2
    NGSS

    In this activity, students will learn about how human lifestyles cause the greenhouse gas carbon dioxide to be released into the air. They will explore how greenhouse gases contribute to global warming and develop a plan to help their school reduce its carbon footprint.
