Grow kids' love for science with at-home experiments

Help your kids become master scientists in school with these fun (and easy) at-home science projects. So put on your gloves and goggles – and let’s get to experimenting.

Grow Egg Crystals

Growing crystals is easier than you may think. All you need for this project is: egg shells (empty and dry – you can also use plastic eggs, but the results are slightly different), glue, a paintbrush, an egg carton, and alum powder that contains potassium.

Paint the eggshells with a thin layer of glue, and while it’s still wet, sprinkle it with the alum powder. Then let them dry overnight. The next day, use food coloring (or egg dye) in 2 cups of very hot water. Then add ¾ cup of alum powder and stir it completely. Once the powder is dissolved, drop in the eggs and let them sit for at least 12 hours. The longer they stay in the solution the larger your crystals will be.

Create a Rainbow Flower Bouquet

This activity is exactly what it sounds like – and it’s the perfect way to celebrate spring and summer! All you need are small glass jars or glasses, food coloring, water, and white flowers. Have your child pick the flowers – or take a trip to the store to pick some up. Mix the food coloring and water in the glass jars: 20 drops of food coloring for each ½ cup of water. Cut at least 2 inches off of the flower stems and set them into the colored water. After about 24 hours, you will start to see your flowers change color!

Explain to your little scientist how it works. Freshly cut flowers draw up water through the stems, like a straw. When the water reaches the petals the water evaporates through tiny pores, but the dye cannot evaporate so it stays, eventually turning the flowers a different color.

Create a Sparkly Explosion

Similar to a volcano – only more fun! You will need a tall vase, baking soda, vinegar, food coloring, blue glitter (you can use any but this color seems to work the best) and a pan to catch the explosion.

Place your vase in a pan, and drop 2-3 tablespoons of baking soda in the bottom. Add 6 to 7 drops of food coloring and 1 to 2 teaspoons of glitter. Quickly pour ½ of a cup of vinegar – and watch out for a sparkly explosion!

If your child is old enough, explain why the explosion happens. Baking soda is a base and vinegar is an acid. Mixing together acids and bases creates a reaction, which is why combining these two resulted in a type of explosion.
