3rd - 8th Grade Science Projects Activities : Page 8

This science fair project idea explores whether a plastic slinky works as well as a metal slinky when walking it down the stairs.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

This science fair project idea identifies trees using a dichotomous key.

What is topography? Kids find out by learning to make and read a topographic map in this awesome science fair project idea.

This science fair project demonstrates the magic of arches by challenging students to stack telephone books on top of eggs without breaking them.

In this fun project, use a memory game to test various age groups and determine whether aging directly affects short-term memory loss.

This science fair project idea studies which brand of wintergreen candy produces the most sparks in the dark.

Science fair project which identifies the most effective insulator that you could use to make a winter coat by comparing how well cloth and cotton trap heat.

This science fair project idea explores plant growth from a bulb, root, and a stem and investigates asexual plant reproduction.

Kids will discover the meat science behind the meat they eat, and find out how to use safe chemistry to make meat more tender.

The objective of this science fair project idea is to examine light refraction as it passes through liquid crystals.

Science fair project which teaches you how to make your own homemade glue by combing curdled milk with baking soda.

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

This project determines what category of person is most likely to be ticklish.

Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.

Discover whether a metal will expand under hot water.

Find out whether matte or shiny nail polish lasts longer.

In this science fair project, we'll use a liquid crystal thermometer to find out whether exercising makes a difference in people's temperature.

Determine whether butterflies like to drink sugar water, salt water, or plain water.

This science fair project idea compares biodiversity between drops of water.

This science fair project idea examines the reason boats are shaped and engineered.

The objective this science fair project is to determine whether a bigger bag will allow a homemade hot air balloon to fly higher than smaller bag.

This science fair project idea determines which method of hand cleansing is the most effective.

This science experiment tests if dog saliva can really help heal wounds.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.

In this science fair project, you'll make a "ghost" appear in a test tube, and learn about what happens when hot water and cold water interact.

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

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

This science fair idea examines hydrogel superabsorbent polymer crystals. They can absorb 500 times their weight in water. Can they absorb other liquids too?
