Science experiments for kids don't have to be complicated to be educational and fun. Each of these experiments takes about 30 minutes, and uses simple ingredients from around the house.
1. Dancing Raisins
Fill one glass with clear soda, and another glass with water. Place the raisins in each glass, and watch how they dance in the glass with clear soda. The gas bubbles from the soda carry the raisins upwards. When they pop, the raisin sinks again.
2. Sink or Float?
Fill two large clear containers with water. Ask you kids to gather small items from around the house to see if they'll sink or float. Before you test them, have you kids write a list of the objects and predict if they'll sink or float. Now, test them out! Now that you have some experience, is there anything else you'd like to test?
3. Shiny Pennies
All you need are some dirty pennies, vinegar, and dish soap for this fun experiment. To make it even more fun, see if other liquids will clean the pennies. Click here for the full experiment.
4. Color Changing Celery
Got some celery in the fridge? Cut the end off a piece of leafy celery and put it into a cup of water and add food coloring. Watch how plants change color over time. You can also do this with a light-colored flower.
5. Bacteria Science Project
6. Mixing Impossible
7. Exploring Colors With Baking Soda / Vinegar
How fun does this look? One reader said this kept her kids busy for an hour. Take eye droppers or pipettes and sprinkle some vinegar on a tray of baking soda. Watch the color bubble and make different patterns. See the full experiment here.
8. Mini Volcanos
This is a real crowd-pleaser, and your kids will be begging to do it over and over again! All you need is baking soda, vinegar, and food coloring. We found a version for younger kids and a version for older kids.
9. Famous Women In Science
10. What's that smell?
Gather some everyday household scents and little containers for this fun mystery game. See the full activity here.
11. Mystery Object
Put scraps of different cloth, like velvet, wool, cotton, or leather; metal objects, wooden spoons/toys, pieces of aluminum foil, and any other interesting objects into a "feely bag", invite students to place hands inside, feel & describe different textures
12. Sugar Water Rainbows
With some water, food, coloring, and sugar, your kids can learn about solutions and mixtures in a colorful new way. See the full experiment here.
13. Painted Nature
Have students search for natural objects in nature and bring them into the classroom to closely observe and paint. Discuss the natural colors and features of these objects. They'll be closely observing natural phenomena, looking for signs of life and growth, and using their senses to experience natural materials.
14. Magnet Fun
Dump out a selection of metal objects onto the table and ask your kids to help you “clean up” by using the magnets to pick up different objects and sort them into containers. They'll learn which objects are attracted to a magnet and which are not. They will also practice skills of classifying and sorting.
15. Will it melt?
Gather a range of materials (within reason) and put them in a muffin tin. Ask your kids about how temperatures can get high, especially on hot days. Ask your kids to hypothesize about what will and won’t melt. Then put it to the test!
16. Traveling Rainbows
Use test tubes or cups, thin strips of kitchen paper towels, water, and food coloring to create a chain that looks like a traveling rainbow. Kids learn about absorbency and color mixing.
17. LEGO Boats
Challenge your kids to build their own boat out of LEGO bricks. It's a great way to get them thinking about engineering and design. For an added challenges, only give them a certain number of pieces. Once everyone has finished building, put the boats to the test in a tub of water. Add pennies a few at a time to see how many each boat can hold. Talk to students about how weight and design matter. Reflect on good designs and help them understand why they worked well.
