Science fair project that determines whether lettuce that is harvested gradually yields more produce than lettuce that is harvested all at once.

This science fair project idea examines whether plants are still able to grow normally if they are turned upside-down.

Take a closer look at your furry friend (or the furry friend of a neighbor -- with permission) to discover if communication exists between cats and humans.

In this project children discover, identify, and sort seeds from a variety of fruits and vegetables

Boost your preschooler's attention to detail by getting her to explore the differences between two different pumpkins: large and small.

Kids will build a turtle habitat in order to observe the climate preferences of this cold-blooded reptile.

This is a fun and inexpensive project and it's a great way for your child to build basic geometry skills, like shape recognition and pattern/angle familiarity.

In this activity, your child will be challenged to build a tall tower out of building bricks! The instructions include questions prompts to guide students through the design challenge.

Do different types of oil mix or stack? Find out in this science fair project idea!

What animals are most popular? This project affords practice in data-collection, record-keeping and data-analysis through the investigation of this question.

In this fun guessing game, your child uses his sense of smell and taste to figure out what is in the container. Here's how to play:

This science fair project idea explores whether the process used to dry the beans we eat for food renders them unviable.

The objective of this science fair project is to explore the relationship between acidic and basic compounds.

Check out this fun science fair project idea for 1st grade: a solar eclipse model that demonstrates total, partial, and annular solar eclipses.

Make a backbone model to explore human anatomy and life science.

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.

This experiment challenges students to forecast the weather based on the surrounding areas' weather.

Check out this cool science project idea to learn about rocks and explore the cycles of formation, breakdown, and reformation of rocks in the Earth's crust.

Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

Help your second grader observe the phases of the moon, and then let the fun loose: he'll get to chart his observations with marshmallows!

Get ready for a yummy taste test! Just pour the milk -- and make sure you have some chocolate chip cookies on hand.

In this science fair project, kids measure how weather conditions affect how fast a puddle evaporates.

Uh-oh! Is that a pill sitting on the counter or a piece of candy?

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

Cleaning can be a chore, but not with this sudsy experiment!

This science fair idea is a great way for kids to explore static electricity. Kids will give a comb a static charge and watch as it separates pepper from salt.

By incorporating natural materials and the powers of observation, your child will become a backyard naturalist while building early writing and drawing skills!

In this science fair project, young children notice and track changes in trees throughout the year.

Will increasing the amount of salt in water effect how slow or fast the water freezes?
