2011 VIRTUAL SCIENCE FAIR ENTRY: The objective of this science fair project is to develop a microcontroller and circuit that can conduct electricity.

Here's a simple science activity that will help your child better understand how wells bring us water.

Your preschooler can learn how to siphon water with just two bottles and a plastic tube in this fun, educational science activity.

Research and understand basic computer science. Build a simple computer, following instructions found online. Design a new or improved feature.

In this design challenge, students will be tasked with creating a bouncy ball polymer!

Learn about the growing app design field by designing a new or improved app for smartphones.

In this exciting design challenge, your child will use design thinking skills to create a mixture that can inflate a balloon.

In this challenge, students are tasked with creating an insulated cup that will keep beverages colder for longer than a regular cup.

Make a periscope with milk cartons and mirrors! This preschool activity is great for playing secret agent and learning simple physics.

In this challenge, students are tasked with creating a model roller coaster that a marble can travel through.

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

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:

In this activity, students will think about the form and function of household objects as they compare and contrast kitchen serving spoons of various sizes and designs.

Tin can phones offer something modern versions don't—a fun project to make with a friend, and a dramatic illustration of vibration and sound waves.

In this open-ended activity, students will be given a small quantity of three types of materials and asked to design a prototype for “something that will improve the school.”

In this activity, your student will be invited to build a chair out of building blocks that is designed to meet the specific size and shape of a small doll or toy figure.

Make your own greenhouse - out of a balloon! Your child will learn how greenhouses work as they plant radish seeds and watch them grow.

In this activity, students will create a stop motion animation by creating a clay figure and taking a series of digital photographs.

In this design challenge, your child will make a bottle rocket using typical household items.

In this activity, your child will transform an egg into a glowing, bouncy "ball" that they can play with.
