Third-grade practical science activities

Practical science activities engage children more than anything another subject in school. Significant ideas are easy to grasp when children see them done. The following third-grade practical science activities are enjoyable to children when done at home or in school. It is also well-ordered fair science projects for children to discover when they are alone.

Demonstration on Play-Doh

Demonstrate to children the piles of earth layers, with the use of Play-Doh, and let them take the core sample.

Create sun prints for display

This project requires a special paper that is easy to get and inexpensive. From the project, children learn chemical reactions from the sun’s control to make unique artwork.

Project videos of stars

Please make use of YouTube videos to explain to them why stars are visible at night only

Use paper clips and magnets to demonstrate laws of gravity

The use of magnets in the classroom for children is exciting. Do natural and straightforward experiments to explore the impact of magnets on metallic objects and laws of gravity.

Create fossils from glue

Cast fossils from natural objects molded from school glue. Attempt this before visiting the history museum.

Discover buoyancy from water balloons

Pour different solutions (plain water, salt water, oil, etc.) into water balloons and put them in a big water bucket to test buoyancy.

Use jumping goop to discover static electricity

To demonstrate static electricity to third-grade children, attempt to rub a balloon on your head.

Make natural-dye markers

Teach children the procedure of mining natural dyes and make your markers, and let children utilize markers to develop beautiful masterpieces.

Create bouncing bubbles

Inspire these kids to create bubbles out of mixed soap solutions.

Crystallize fall leaves

All children like crystals. Help them crystallize colorful leave and use them as a classroom decoration.

Locate the center of gravity for robot

Print a robot drawing, cut it, then color it. Using glue stick coins to its back and let students locate the center of gravity.

Build an umbrella

Using simple and readily available household supplies, challenge children to build the best umbrella.

Study the impacts of soil erosion

Make a comparison of the effects of rain on soils covered with grass and bare soil. Let the children predict the soils that will withstand soil erosion.

Using milk and cookies demonstrate scientific methods

Let children dip cookies into milk and document what they see.

Blow water through a whistle

Let the kids explore the science of sound by creating whistles out of water and straws.

Build marshmallow catapult

To develop this simple device, you will need the following rubber bands, pencils, and an old tissue box. Marshmallow catapult will allow kids to appreciate gravity, air resistance, and trajectory

Investigate water temperature using salt and ice

This experiment investigates how salt and ice influence temperatures; it is a compelling example of freezing point and heat transfer.

Colors experiment

Use markers and coffee filters separate from mixed colors. This a good chromatography science project for kids.

The science behind bath bombs

Bathroom bombs make bathing enjoyable and fun. Investigate the chemical reactions that make this possible, and be careful.

Grow sweet potatoes

Sweet potatoes sprout out of tubers, and under favorable conditions, new shoots sprout. This experiment discovers the science behind cloning.

Convert crayons to rocks

Illustrate the influence of pressure and heat on pencils. It explains different kinds of stones to your students and makes an excellent introduction to geology.
