Here's a fun activity to help build thinking skills in young first grade scientists, and to encourage them to have a blast exploring the mass and volume.

Use chemical analysis to identify a variety of mystery powders that look the same but actually have very different properties.

In this challenge, students are tasked with creating a car that can be powered by a balloon!

This experiment provides a graphic illustration of the chemical reaction that occurs when you activate a hand warmer.

This experiment will use computers to examine how the famous Mandelbrot set can be manipulated in fractals.

In this experiment, you will be making your own paper flashlight by conducting electricty with graphite.

In this microwave plant experiment, find out whether microwave radiation will affect radish seed germination. Will it help or hinder the plants' growth?

Determine whether fresh vegetables have more calories or less calories than canned vegetables.

Get a cool middle school chemistry project idea on how to determine whether a physical or a chemical change has taken place.

The objective of this project is to examine the ways in which a passive solar house may contribute to conservation of energy.

This middle school project examines the strength of horizontal versus vertical pointing eggshells.

Find out which part of a flame burns wood the fastest and also if this is true for all types of flames such as candle-flame, burners, and lighters.

In this experiment, you will evaluate whether or not a diet that is supplemented with "brain-enhancing" foods can help improve memory.

Invite your middle schooler to bungee jump ... with eggs! This experiment will demonstrate Newton's laws of physics in an entertaining way.

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

This weather spinner will improve observation skills by encouraging children to examine and track weather details and patterns.

Based on the concept of water's "freezing point," this activity entails the lowering of water's freezing point to chill ice cream!

Water can go from solid to liquid to gas...but how does popcorn go from kernel to snack? Invite your first grade scientist to find out.

Demonstrate the relationship between mass, volume and density. Measure displaced water, and weigh object to calculate mass and density.

Build basic projector out of ordinary materials. Create several color transparency slides, demonstrate your creation.

In this activity, you child will learn about how heat changes food. On the next sunny day, head outdoors to make a treat in an outside oven! Here's how:

Learn whether dark green and leafy veggies tend to have a higher Vitamin C content than lighter green varieties.

Research overview of architecural acoustics. Design and build a whispering wall from wood or plastic. Test which materials work best.

Wonder why bugs always fly around your lights at night? This experiment determines whether insects are attracted to the heat or the light.

Demonstrate the properties of pressure and surface tension to explain how water can stay inside an upside down glass using cardboard.

Determine if gender affects the ability to identify different smells.

This project determines the age of a tree using a growth factor chart instead of cutting the tree down to count the rings in its base.

Find out whether we can create motion in a dish and as a result, create a wonderful and colorful show.

Combine your child's natural curiosity with his developing classification and writing skills by helping him create a backyard field guide.
