First graders are learning to think like scientists. What better place to start, then by raising tadpoles? This hands-on activity explores science in action!

This science fair project idea discovers whether there are some objects that do not fall at a constant rate.

Observe with your third grader what happens when food starts to decompose, and boost science skills simultaneously with this experiment!

Have your child try this classic experiment that demonstrates circular motion using a bucket and rope. Be careful, you might get soaked!

Make your own marshmallows and mix up some very interesting third grade chemistry lessons while you're at it!

Have your child build a model of a coral polyp, one of the tiny animals that composes a coral reef.

In this experiment, you experiment with laser jet toner, a magnetic fluid, as it moves, bubbles, and forms unique shapes.

This science fair project looks one of the most important factors affecting seed germination: water. A fun and easy plant biology experiment for 3rd graders.

This science fair project idea investigates if fats add to the flavor of food.

Combine science with reading and art to help your first grader create an attractive holiday gift for a beloved friend or relative.

How do crystals form? In this science fair project, students will use three different saturated solutions to see how different minerals form crystals over time.

Your child might have noticed how bubbles quickly lose their colors and pop. Check out this creative way to make those bubbles last longer.

You and your child can create this beautiful butterfly mobile for hanging anywhere in the home (and learn about this magical creature while you're at it).

Explore the properties of light and color using photographic filters. Take pictures of color spectrum, compare results of different filters.

This science fair project idea explores the fastest average speed a human can talk.

Science fair project which determines whether the size or the thickness of a piece of paper has an effect on how many times it can be folded in half.

Learn about different fern fronds with your third grader as you create lacy, natural decorations on your Easter eggs this year.

It's food. It's Thanksgiving tradition. And guess what: Cranberry Sauce is also science! Try our simple recipe/experiment.

This science fair project idea demonstrates that plants give off water.

The fish most kids see is usually filleted, and it's hard to see how it came from a lake or sea. This cool gyotaku activity blends life science with art!

Teach your first grade scientist the difference between liquids and solids using maple syrup.

The garden is the perfect place to practice math and science with preschoolers. Get digging (and counting, sorting, observing at the same time!)

Have your little astronaut create her own crater-filled moon with this fun craft project that encourages learning about the final frontier.

This science fair project idea investigates how images are influenced by changes in light.

Roasting pumpkin seeds makes for a great Halloween activity, and a healthy snack!

This science fair project idea demonstrates how air resistance contributes to denser objects falling faster than less dense objects.

The buoyant force of water explains why some objects float in water. But why do some objects sink? Find out in this physics experiment and learn about density.

Learning about how plants grow is a building block in the early grades science curriculum. Put a fun twist on this life science concept with these cup monster friends!
