Looking for an enjoyable evening activity you can do with your kids? Study the stars: help them learn about constellations by making one of their own.

In this project, all you need is a protractor to learn how to use the altitude of Polaris to find latitude on Earth. Polaris is also known as the North Star.

Introduce your fourth grader to the concepts of solstices by observing the length of her shadow on the shortest day of the year, compared to other solstices.

Find the North Star, and measure your latitude! The purpose of this science fair project is to find latitude and learn about geographic locations.

Learn how to tell time by the sun with this cool science fair project idea that tracks how the accuracy of a sundial changes over time.

This 4th of July, explore fourth grade science and make some safe fireworks in your own backyard using soda pop!

Make a planter full of delicious seasonings and classic grilling vegetables, great for a Fatherâs Day gift or a fun start-of-summer outdoor activity.

Make a spring collage with your child to get them outside and those creative juices flowing!
