Kids these days spend most of their time sitting in front of the television. In addition to common health problems like obesity, watching TV for long hours can also hinder brain development in children. Conducting fun science experiments at home will not only keep your kids occupied, but will also exercise their brains. So, why don’t you help your kids try some of these fun filled science experiments that will get them thinking?
8 Science Experiments That Your Kids Will Enjoy Doing
Gravity Defying Water:
So, what will happen when you invert a glass of water upside down? The water will pour down due to gravity. Let’s conduct a little science experiment where the water doesn’t come down. Fill a glass right up to the top with water and close it using a piece of cardboard. Make sure there are no air bubbles in the glass. Now, hold the cardboard in place and turn the glass upside down. Remove your hand. You’ll see that the cardboard and water stay in place defying gravity. So, why does this happen? Go, figure.
Lava lamps are fun to make and also make for a good science experiment. You will need a bottle, water, vegetable oil, food coloring and a few Alka-Seltzer tablets for conducting this experiment. First, fill ¼ of the bottle with water. Now fill up the bottle with vegetable oil until it is almost full. Wait until the oil and water separate and then add some food coloring. You will see that the food coloring will mix with the water. Break an Alka-Seltzer tablet into small pieces and put them in the bottle. Enjoy the show and add another Alka-Seltzer table once the fizzing settles down. Now, why don’t you try finding out the reason for this awesome show of bubbles?
Want to send a few secret messages to your friends? There is a very easy to do that. All you need are some lemon juice, water, cotton buds and paper for doing this easy science experiment. First, dilute the lemon juice with a few drops of water and mix it well using a spoon. Dip a cotton bud into the solution, squeeze it and start writing your secret message on the paper. Once the juice dries off, it will be completely invisible. For reading, just heat up the paper by holding it close to a light bulb. Once you are done with your messages, try finding out what makes a humble lemon juice so special.
Do you prefer apples to potatoes? Or, is it the other way round? Peel an apple and a potato and cut them up into identical pieces. Close your eyes and pick one. Now, hold your nose and try eating the piece that you picked up. Can you tell if it is an apple or a potato? Actually, it is quite tough to recognize foods without the sense of smell. Try finding out why.
Plant some seeds in a container and watch the plants grow. You will have to fill up a suitable container with potting soil and plant the seeds inside. Take care of plants and water them carefully. Monitor if they are receiving just the right amount of sunlight, if not, place them in a different location. The seedlings will start sprouting in no time rewarding you for your efforts.
Learn about static electricity the fun way with this simple and easy science experiment. Rub 2 inflated balloons against a woolen fabric one by one. Now, try bringing the balloons together. You will see that they do not want to get close to each other. Why does this happen? Another one, rub an inflated balloon against a woolen fabric. Now, put an aluminium can sideways on a table and bring the balloon near it. The aluminium can will start rolling closer to the balloon. Try moving the balloon away, the can will follow suit. Makes for interesting stuff to learn, don’t you think?
Normally, eggs sink when dropped in water. Want to make eggs float in water? All you need for doing this science experiment is an egg, some water, a glass and salt. Fill the glass halfway up with water. Now, mix about 6 tablespoons of salt with the water. Fill up remaining part of the glass with normal water making sure that the salt water in the bottom and normal water don’t mix. Drop an egg inside the glass. You will see that the egg sinks through the normal water but stays afloat the salt water. Now, why does this happen?
You will need a bottle, some water, liquid dish soap and some glitter for creating a tornado in a bottle. Fill 3/4th of the bottle with water and add a few drops of dish soap into it. Add some glitter and screw the cap on tightly. Invert the bottle and hold it by the neck. Now, spin the bottle in circular motion for a few seconds and look if you can see the tornado forming in the water. If not, try spinning again. It might take a few tries to get it right.
