Best 11 Science Activities for Kids: Very Simple Experiments

Easy Science Experiments to Do at Home | Best Science Practicals For Kids 

Experiment #1: Gravity-Defying Magnets

Hang paperclips from a ruler or dowel, or it can dangle automatically, as they should. Place hard magnets on a ruler and use them to get the paperclips to stand straight up to illustrate how other forces can overpower gravity.

Experiment #2: Self-Inflating Balloon

                             

If you put bakery soda in an empty container and vinegar in a ball as you fill the ball over the mouth of the bottle, the resultant gas would be adequate to inflate the ball alone. A variation on the experiment of vinegar and bakery soda. Bonus: Unlike a vinegar-baking-soda volcano, this procedure is less hazardous.

Experiment #3: Easy Sundial with Rods

Making a home-made sundial is one of the least readily available science tests: You just want a dowel, a decent bolt, a sheet of paper and a label. Label every hour the location of the shadow of the dowel and you can learn about the earth's rotation with a quick opening. See if your sundial says you right time to play outdoors the next day.

Experiment #4: The tiny Volcanic Eruption

In science, when you have an acid and a base together, they can erupt in your face. The baking soda in the mixture was the base, and the vinegar is an acid. So when mixed together they have a chemical reaction and release carbon dioxide. Cool! Really Cool!

Experiment #5: The magical milk

If you drop a few drops of food coloring into a shallow bowl of milk, they will remain as self-contained blobs. When you put a little dish soap on a toothpick or a Q-tip and hit the food coloring, the colors will magically swirl around. It's all about surface tension: the food coloring sticks to the surface at first, then the soap induces a chemical reaction that breaks the surface tension.

Experiment #6: Bottle Tornado

Connect two two-liter bottles with water inside, turn them upside down, shake them, and watch a tornado develop its distinctive funnel shape. You may also place glitter or small objects in the bottle to simulate how a tornado's winds will whirl objects around in real life.

Experiment #7: Egg inside the bottle

Can you imagine a peeled hard-boiled egg fitting into a bottle without smushing into a major mess? If you put a burning piece of paper in the bottle first, it could work. The air in the bottle expands as the paper burns, increasing the pressure. The temperature drops when the fire runs out of oxygen, and the air contracts, sucking the egg through the bottle opening. This is an extra-dramatic experiment because of the fire and the egg sucking.

Experiment #8: Bag of Icecream

At long last! An experiment that you can eat. Combine the ingredients in a bag, seal it, and give it a good shake for 10 minutes. Will they grasp the concept of energy transforming matter states? Maybe, but in any case, you're in for a treat. Actually, kids will get to know about the states of matter and transformation of states of matter. 

Experiment #9: Floating or Sinking things– Density based

Making kids find out what makes those things sink and float is a good way to teach them about density — and an even better way to get them to practice the scientific method if they first make a hypothesis about what would sink and float before measuring the effects. Kids will learn about the Density of a substance.

Experiment #10: Flying Tea Bag (Rocket) : Hot air rises

Want to show kids the hot air rises in a fun way? Remove the tea from a tea bag, hollow it out, stand it up, and (carefully) light it with a match. Since the hollowed-out bag is so light, it rises with the hot air and transforms into a flying tea bag. The warm air rises! You've just produced a convection current of air that is flowing inwards, towards the burning tea bag, and rising as a hot air column. Only when the tea bag became lighter (smoke has weight, too!) could the rocket rise. This fundamental concept is well known to everyone who has seen a hot air balloon.

Experiment #11: Brown Apples: Oxidation of Apples                

What's the safest way to save an apple from browning? To find out, take the quiz! Slice an apple into slices and soak each slice in a different liquid. Then remove them from the oven, put them on a tray, and check for brown color after three, six, and so on. This not only allows students to test the properties of various liquids, but it also allows them to practice the scientific method by allowing them to make hypotheses about which liquids would be the most effective.
