Ethanol can be used as an alternative fuel! The purpose of this experiment is to identify a starch plant that produces the largest quantity of ethanol.

Determine the relationship between the speed of a sound and the temperature of the air it passes through.

Determine whether a hot liquid cools off faster when liquid is added before or after a two minute wait.

Determine which seeds are most likely to survive harsh winter conditions (low temperatures).

Using simple materials found around your home, you can reinforce the static electricity concept by helping your child build a simple device with zapping power!

Test whether cutting up meats will make it cook faster than just cooking it whole.

This project determines whether Styrofoam, paper, or plastic cups are best for preventing ice from melting.

Explore the best way to store popcorn kernels. It examines the impact of moisture and temperature on unpopped kernels.

Store seeds under three different environmental conditions. Plant seeds in carefully marked groups, watch them grow. Compare results.

Determine which environment keeps an ice cube frozen for the longest duration. Inspect and record your observations when cubes melt.

When you rub a balloon on your head, your hair stands up; but is that true for everyone? Does hair color affect static electricity?

Explore the wattage of microwaves in relevance to cooking time.

This project compares different liquids and the freezing, melting and boiling points of liquids.

Help your first grade scientist learn about metamorphosis by observing the life cycle of some interesting creepy crawlies.

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!

Study the impact of environment on seed germination among three materials: soil, paper towel, and cloth. Note when seeds germinate and how well they germinate

see whether all liquids evaporate at the same rate. In other words, does water evaporate at the same rate as juice?

Investigate the advantages of the use of ceramics in engines such as the tiles used in Space Shuttle. Use iron filings and magnets.

Compare air temperature with the infrared temperature from a reflecting surface at different times of the day, in shade and in sunlight.

Salmonella and E.coli are common food contaminates. This experiment measures the time it takes for E.coli and Salmonella to reach hazardous levels in fish.

This homemade barometer allows your little scientist to contemplate and compare different air and weather conditions.

How powerful is the reaction between baking soda and vinegar? Find out here!

This activity is a fun way to "go fishing" with your preschooler, while learning about the concepts of freezing and melting.

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.

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

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

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