If you are looking for the best science experiments to do with your kids, there are plenty of ideas on how to conduct them. The following articles will give you a variety of ideas, from Making a tornado in a bottle to salt circuits to batteries made from eggshells. In addition to these, you can even try making a battery from lemons and salt. Hopefully, these articles will provide you with the knowledge you need to conduct your own experiments at home.
Making a tornado in a bottle
For this experiment, you will need two large, clear plastic bottles. Fill one with water, then add a little bit of dish liquid, food colouring, and other debris. Connect the empty bottle to the water-filled bottle using duct tape. Once the water starts flowing, spin the jar around. You’ll see a funnel cloud. Repeat this process many times until you see a tornado.
Making a battery with lemons
The basic idea of a battery is two metals suspended in an acidic solution. A lemon contains a lot of sour juice that can be used to create electricity. This juice can be used to make light by adding a red LED to the mix. There are several different colours of LEDs that can be used for this experiment, but red ones require a lower voltage to glow. You can purchase low-current LEDs at online stores such as Amazon or Mouser electronics.
Making a salt circuit
To begin, fold two pieces of card stock in half and add a paper clip on the bottom. Each student will need two folded pieces. Place the salt in a box lid or any other container with sides. Place two small cups or jars of watercolours in the tray. Ask students to draw designs on the card stock starting at the paper clip and ending at the folded edge. The more elaborate the design, the more likely the electrons will follow the circuit.
Making a battery with eggshells
The world’s energy problems may have found a solution in a simple way: chicken eggshells! Scientists from Japan and Canada have discovered that eggshells can be used to make a battery, and they’ve been able to store lithium within the shell’s carbonate layers. This new technology could revolutionize the way batteries operate. It may even be able to power electric cars! While the scientists haven’t tested this process on free-range eggs yet, they’re hoping to eventually make a battery out of the eggshells themselves.
Making a xylophone
One of the most basic physics experiments to perform at home is to make a xylophone. You can experiment with a glass jar filled with water at various levels. You can then use a wooden stick to tap the jars, measuring the pitch and volume of sound waves as they travel from the jar to the xylophone. This activity will require a bit of water, but will provide hours of entertainment for you and your children.
Making a battery with baking soda
To make a battery, you will need two metals, preferably copper wires, and a conductive material, such as dirt, saltwater, or a lemon. You can also use a pinch of baking soda to create an electrolyte, which is a substance that conducts electricity when exposed to an electrical current. Add these three substances to a plastic container and put it on top of your push pins. You will want to place a test tube above each push pin, so you can observe the formation of gas.
