In this activity, your learner will be challenged to create their own tic-tac-toe grid out of building blocks.

This tricky building block challenge asks your learner to think creatively. They will work on their divergent thinking skills as they try to fill up an index card perfectly with building bricks.

This science fair project idea explores the egg's thin membrane.

Science fair project which determines whether plants are able to get enough nutrients from different types of garbage.

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

This science fair project will help students learn about non-vascular plants, such as mosses.

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

Science fair project that compares the freezing temperature of salt water and freshwater in order to learn about supercooling and condensation nuclei.

In this science experiment, observe convection currents forming and learn about how heat energy moves in liquids from hot to cooler areas through convection.

This science project teaches students the relationship between compost and plant growth. Students conduct an experiment with different types of compost.

In this experiment, students find out what happens when a less-dense fluid interacts with a denser one, replicating the effect of cooler solid rock on magma.

This science fair project idea explores alcoholic fermentation at work by making your own soda.

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.

Experiment with buoyancy to learn how a submarine rises and sinks in this classic science experiment.

In this experiment we will be determining whether birds prefer certain colors of seed.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

Science fair project that identifies the differences between soils from different environments and attempts to figure out why those differences exist.

The objective of this science fair project is to set up a compost bin to convert food scraps and organic waste.

In this simple science project, learn about what causes dew and what affects dew formation with a drinking glass, ice, and a soda bottle.

Did you ever add salt to pasta? Did it help cook the pasta faster? If not, find out in this science fair project idea.

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

This science fair project on testing water hardness is a great introduction to practical chemistry. Test and learn the difference between hard and soft water.

In this project students experiment with making music using only glasses of water.

Science fair project idea which teaches you how to make butter by separating cream into butter and buttermilk.

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

Discover whether cold or hot water from the faucet will boil faster on the stove.

This science fair project idea studies which kind of rock (sedimentary, igneous, or metamorphic) is most damaged by frozen water.

Science fair project that examines how to grow bacteria in a controlled setting, using simple materials from around the home.

This science fair project idea creates a sedimentary rock and to investigate what takes place during the rock cycle.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.
