Science is fun. It's even more fun when it tastes good. Whether you homeschool your kids or you just want to learn (and eat) something together, we found 15 science experiments that will excite kids' minds and tickle their taste buds.  

Did you know you can easily make edible slime or cook s'mores using the power of the sun? These edible science experiment ideas are truly "brain food" -- try them for yourself! 

1Peeps Science Experiment

Everyone loves Peeps -- and these days, you can find them (in other shapes) year round, so this experiment by Gift of Curiosity isn't just a spring project. Soak Peeps in a variety of liquids and -- after hypothesizing -- see how the sugar reacts to each.

2Engineering Jelly Beans

With just jellybeans and toothpicks, your STEM-loving kids can create building blocks like these found on Lemon Lime Adventures. See how tall they can build a structure before it falls. Take the project a step further and build molecule structures out of the jelly beans and toothpicks as well. 

3Density of Fruit

Want to teach your kids about density? Show with an experiment by EDVentures with Kids where you drop pieces of fruit in a clear bucket of water. Which pieces of fruit float and which ones sink? Take some educated guesses before you toss the fruit in the water. 

4Marshmallow Constellations

Teach your kids about constellations and stars with a hands-on activity from Munchkins and Moms. Using mini marshmallows, toothpicks, and an edible yellow marker, this easy lesson is a great and sweet introduction into astronomy. 

6Dancing Worms

Here's a simple experiment for your budding scientists from Play Dough to Plato. Soak gummy worms in a baking soda mixture. Then pop them in a glass of vinegar. The gas bubbles created by the chemical reaction of mixing vinegar and baking soda will make the gummy worms dance.  

7Solar S'mores

Teach your kids the power of solar energy with this experiment from Lemon Lime Adventures. Make a solar oven using an old pizza box, tin foil, black construction paper, and plastic wrap. Then prep the s'mores ingredients. Set the timer to see how long it takes for the sun to melt it.

8Edible Sedimentary Rock Recipe

Here's a yummy recipe from Rainy Day Mum that doubles as a science lesson on sedimentary rocks (rocks that formed by settling layers of sand, dirt, and shells). Which layer is the oldest? Which is the newest?

9Lemon Batteries

Did you know that you can light up 3-volt LED lights with lemons? Katie from Preschool Inspiration shows you how. All you need are some galvanized nails, copper, LED lights, and lemons. Surprisingly, each lemon produces 0.9 volts of electricity. 

11Edible Igneous Rock Recipe

Did you know that igneous rocks are created when molten rock cools quickly? (Think pumice.) What's cool about this candy recipe from Rainy Day Mum is that it mimics igneous rocks. As the candy cools, it is left with holes -- just like pumice rocks. 

12Candy Agate Slices

Jennifer from Sugar, Spice and Glitter rocks. She created a recipe that doubles as a teaching tool on how geodes are made. By melting a variety of hard candies, your family can make some beautiful and tasty treats that look like agate slices.

13Growing Gummy Bears

Here's a fun experiment from Play Dough to Plato that tastes pretty good too. Hypothesize whether or not gummy bears will grow bigger in salt water vs. regular water. Then see what happens.

14Rainbow Water Soluble Science Experiment

Katie from the Gift of Curiosity has come up with a beautiful experiment where your kids can actually taste the rainbow. The M&M's hard shell dissolves in water and creates a colorful creation.
