Science experiments for kids

You’ll find many experiments can be done using simple ingredients found around the house (with adult supervision, of course). Visit this blog to try out new exciting experiments and discover new information. Try these science experiments for kids and have fun doing them at home, in the classroom, or even for your upcoming projects.

Coffee ground fossils

Kids can better understand how fossils are created by making salt dough out of coffee grounds and pressing various shapes into it (toy dinosaur feet, seashells, etc.). The kids can hang up these coffee ground fossils in their rooms if you make a hole in the top before it dries.

Chromatography flowers

Children will be using coffee filters to separate marker inks in this activity. The kids enjoy seeing which colors were combined to create the final color of each marker. While some markers won’t separate, some marker colors will split into two or more distinct colors.

Water walking

For this one, you’ll need six containers of water: three of clear water, one of red food coloring, one of blue coloring, and one of yellow coloring. Make bridges out of folded paper towels to connect the colored and clear containers as you arrange them in a circle. Your children will be in awe as they watch the colored water “walk” across the bridges and into the transparent containers, mixing colors and allowing them to experience capillarity magic firsthand.

Magic milk

Put a few drops of food coloring in a shallow bowl of milk, and they’ll stay that way — as self-contained blobs. However, if you dab some dish soap on a toothpick or a Q-tip and touch the food coloring, the colors will magically start to swirl. The reason is simple: Surface tension prevents the food coloring from sinking to the bottom at first, but soap triggers a chemical reaction that breaks the surface tension.

Pencils through a bag of water

Children might assume that if you poked a sharp pencil into a bag of water, the water would all leak out. In fact, if you do it correctly, the bag’s plastic polymers will reseal around the pencil, keeping your counters dry (and your kids will be amazed). You can encourage them to consider the chemical components of commonplace items.

Mold science

You can see how different additives (salt, vinegar, etc.) affect the growing of mold on bread in mold experiments, which are always horrifyingly fascinating. You can also observe how mold develops on bread. 

Tea bag rocket

Want to teach kids experiments in a memorable way? Remove, tea and hollow the tea bag. Unfold the tea bag and straighten it out,  to open it like a cylinder. Set it up straight on a plate. Light the top of the bag on fire and it will fly. This happens due to the hollowed-out bag’s extreme lightness, it rises with the hot air and transforms into a flaming, flying tea bag.

Self-inflating balloon

Attach the balloon’s lip with care to the water bottle’s cap. Be sure to leave the majority of the balloon holding the baking soda hanging down so that it doesn’t fall into the water bottle. Once you’re ready, lift the balloon so that the baking soda spills into the bottle, then watch the balloon expand. Bonus: Unlike a volcano made of vinegar and baking soda, this experiment is less messy.

Lava lamp

Add vegetable oil to a glass until it is about 3/4 full. Once the liquid in the cup is about 1-2 inches from the top, add the coloured water.

Keep it from overflowing. Water and oil do not mix, and the oil does not change color because the food coloring is water soluble. By observing oil and water coloured with food coloring, children can learn about density. For added fun, you can add an antacid tablet. When you do, you’ll notice that bubbles are starting to flow everywhere like in a cool lava lamp.

Tornado in a bottle

Hold two, two-liter water-filled bottles together, turn them upside down, shake them, and watch as a tornado takes on the shape of a funnel. To demonstrate how a tornado’s winds would actually toss objects around in the real world, you could also add glitter or tiny objects to the bottle.

Egg in a bottle

Can a hard-boiled egg that has is peeled fit inside a bottle without making a big mess? If you first put a burning piece of paper in the bottle, it might be possible. The bottle’s burning paper causes the air inside to expand, increasing pressure. The air contracts as the temperature drops and the temperature of the fire decreases, sucking the egg through the opening of the bottle. This experiment is especially dramatic because of the fire. 

Color cabbage

By literally dipping cabbage (or celery, but cabbage is more colorful) in food coloring, you can demonstrate to children how plants move water from their roots to their leaves. This experiment can be used to illustrate capillary action using this as an example.

Key takeaways

• Not every science experiment calls for pricey lab supplies or potentially harmful chemicals. 
• You can create a many cool projects using common household items. 
• Kids adore the simple science experiments that are fun to do and anyone can try.

FAQs

Q1. How far is the sun from us?

Answer –The distance between the sun and the earth is 93 million miles. Even light takes eight minutes to travel from the sun to Earth. Light moves so quickly that we cannot even see it.

Q2. What causes birds to migrate south for the winter?

Answer – In areas with harsh winters, birds have trouble finding food. That is why, in the winter, a lot of birds migrate south in order to find the food. 

Q3. Are sharks considered mammals?

Answer –Sharks are fish, despite the fact that some people mistake them for mammals because of their size and the fact that some of them can give birth to live young.
