Are you tired of your kids complaining about nothing to do this summer, or need something to do on a rainy day other than TV? Today I’m going to show you three different edible science experiments. They are fun for the kids, it helps them learn some science basics and they get candy!
Kool Aid Rock Candy:
What you will need:
- Kool aid packs in different colors
- wooden sticks
- canning jars (or just use clear drinking glasses)
1. To begin you will get your sticks ready. First you will dip all the sticks in water, and then in sugar. Place them on parchment and give them a chance to completely dry.
2. Next you are going to make a sugar water that is saturated with sugar (PSA- this is not a healthy snack). To do this you need 1 part water to 3 parts sugar. In a saucepan over medium heat combine one cup sugar and one cup water till dissolved. Once that has dissolved, add 2 more cups sugar and cook until that is dissolved, stirring as you go.
3. Next prepare your jars or glasses. Empty a Kool Aid pack into each jar or glass. (I used a half a pack in a jar) Depending how many sticks you want to make you may need to make more sugar mixture.
4. Set your jars up and place a fully dried sugar stick in each one. You can use a close pin to hold them off the bottom a little if you like. Then just let your kids watch as crystals begin to grow. You can also do a clear jar to have as an example they can see easier. It takes about a week to get a nice piece of rock candy.
5. This experiment shows kids that when you make a super saturated sugar solution like this where no more sugar can be dissolved, it cannot all stay as a liquid. As the water evaporates from the solution, the sugar begins to come out. The molecules collect on the beginning crystals you made on your sticks. So you are making a big tasty collection of molecules!
Dancing Gummy Worms:
What you will need:
- A bag of gummy worms
- Baking soda
- Knife and cutting board
- 2 clear glasses
1. To begin this experiment you may want to cut the worms into smaller pieces, but you can do whole worms as well.
2. Next measure out 3 tablespoons of baking soda and stir into a clear glass filled with 1 cup warm water.
3. Next take a hand full of worms and mix them into the baking soda and water mix.
4. After they are mixed in you will have to wait 15 minutes for the worms to soak in the baking soda mixture.
5. Fill a second clear glass with vinegar
6. Carefully get out a worm and place it in the vinegar. They will begin to bubble and eventually wiggle their way to the top. Just do a few worms at a time for this to work.
7. This shows kid’s a basic acid and base reaction.. When the acid in the vinegar mixes with the bicarbonate in the baking soda, carbon dioxide gas bubbles form. As the gas bubbles rise to the surface they eventually pull the worms with them.
Edible DNA Model:
What you need:
- Bag of Twizzlers
- colored mini marshmallows
1. This project is super simple. Its helps kids learn the structure and make up of DNA in a 3D form. And when they are done it’s edible. This would also be a great activity for a teacher to use when studying the human body.
2. To make the model lay two Twizzlers side by side with space in between.
3. Next you will use your toothpicks and marshmallows to make the inside DNA sequence. Using four toothpicks create a sequence using three marshmallow colors. Then place the toothpicks into the middle of the Twizzlers and poke through so they all hold in place.
4. Now you will cross one Twizzler over the other; make four more toothpicks, this time when you place them flip the sequence around, then join them together.
5. Its that simple, they can study the parts of the model, then have a little treat.
