Here's a fun math and science activity: help your child explore four different kinds of measurement, using their hand and a few simple household tools.

Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

Help your first grader explore the world of scientific measurement by "weighing" fruit with a "water scale"!

Introduce your child to science with something they see everyday--their shadow!

In this science fair experiment, students learn about the scientific principles behind Doppler ultrasound.

Make water and clay play a little more scientific with this hands-on experiment that teaches displacement and shows how an object's shape affects its buoyancy.

In this challenge, students are tasked with creating a model roller coaster that a marble can travel through.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

Look for a correlation between temperature and the intensity of cricket chirping. Measure ambient temperature and sound intensity in decibels.

In this cool science fair project, kids apply basic algebra to learn how to make a PVC pipe instrument while exploring concepts like frequency and resonance.
