There are many engaging and informative science activities for kids that can be done both in the classroom and at home. By using objects found around the house or that can be easily purchased, you can help your students or kids learn about different facets of the Earth such as earthquakes, solar eclipses and the importance of recycling.

  1. The Andes Mountains with Chocolate

    • When you begin teaching about The Andes Mountains in South America during your geography class, you can use chocolates to help describe differences in elevations. This gives the students a visual demonstration as well as a treat to enjoy once the activity is to complete. Buy a bag of Andes chocolate mints and begin stacking them. As you continue to stack more and more mints on top of each other, explain the differences in elevation of the Andes Mountains.

    Beach Ball Toss

    • You can use beach balls to teach about how much land and water are found on Earth. Purchase a beach ball or other lightweight ball that is decorated like the Earth. Toss it from student to student. When each student catches it, he must announce whether his hand landed on water or land and write that on the board. Continue this with every student. At the end of the activity, compare how many times a hand touched on water and how many ended on land. This activity gives students an idea of the proportion of land versus water on Earth.

    Recycling Poem

    • Use poetry to each your students about the importance of recycling and it's effect on our planet. First, as a group, read Shel Silverstein's poem "Sarah Cynthia Sylvia Stout," about a girl who refused to take the trash out. Then have a group discussion about the negative effects of not taking the trash out. Use this as a chance to explain not only the importance of properly disposing of trash but also organizing your recyclables. This activity can extend to students' homework by having them bring in five different items that can be recycled.

    Make a Solar Eclipse

    • This is an activity that can be done at home with just a quarter coin and a flashlight. When your child is learning about astronomy in school, you might want to teach her about how a solar eclipse works. Hold a flashlight in front of your child at eye level, and aim it at the right side of her face. Have her hold out the quarter in front of her face and then turn on the flashlight. Position your child so that the coin is evenly spaced between the flashlight and her face. Explain that the quarter is the moon, and demonstrate full and partial solar eclipses in the way the coin blocks out light.

    Make an Earthquake

    • Show the dangers of an earthquake and it's impact on the earth by making an earthquake with a slinky and piece of sandpaper. Place the sandpaper down on a table or desk, and place the slinky on it's end on top of the sandpaper. Instruct your child to grab the sandpaper and pull it toward him a few inches. When the child notices the bottom of the slinky stayed still, while the top moved back and forth, have him shake the sandpaper a few more times, increasing the force. When the slinky still does not topple over, explain what you are demonstrating. During an earthquake, this type of shaking can happen more than 100 times within just a few seconds- eventually with enough force, a building can collapse.
