Do plants breathe? Not exactly. They do respire though! This activity will help your child with see that plants are producing the oxygen we need to survive.

Kids will build a turtle habitat in order to observe the climate preferences of this cold-blooded reptile.

Time is an abstract concept that's difficult to grasp. But waiting for the turkey to come out of the oven on Thanksgiving is a concretely yummy experience.

Here's a hands-on activity you can do with your fourth-grader to practice measurement and directly apply the concept of area.

This activity is a great starting point for practicing mental math because it is quick, easy and involves only simple addition facts.

Challenge your third-grader to sharpen her new math skills--and maybe do the planet a favor, too.

To help your child learn how to use a thermometer, try this temperature collecting activity at home.

The Math Monster will save your second grader from repetitive math flashcards. Guessing mystery math facts is a fun way for him to polish arithmetic skills!

Grow a garden with an environmentally-friendly twist by using plant scraps that usually get thrown away.

Engage your children with this fun fall activity that integrates math and science. First, your child will excavate to find leaves. Next, they'll examine them to determine the colors. Then, your child will graph their findings.

The next time you've got a restless second grade earth scientist on your hands, use this experiment to demonstrate crystals and make a tasty treat, too!
