Are you looking for some fun, simple science experiments that you can do with your kids in KS1? Science is an important part of a child's education and these experiments are a great way to introduce them to the world of science. Not only will they have fun, but they will also learn something along the way. Here are some easy science experiments that you can do with your kids in KS1.

The Lemon Battery

This experiment uses a lemon to create a battery. You will need a lemon, two galvanized nails, and two copper coins. Start by pushing the nails into the lemon, one near the stem and one near the bottom. Push the coins into the lemon near the nails. The lemon juice acts as an electrolyte, and the two metals create a chemical reaction that produces electricity. The lemon will start to light up an LED light or a small buzzer. This is a great way to teach your kids about electricity and chemical reactions.

The Dancing Raisins

This experiment is great for showing how density works in liquids. You will need a clear glass, some raisins, a spoon, and some carbonated soda (like club soda). Start by filling the glass up with the soda and adding a few raisins. The raisins will sink to the bottom. Then, use the spoon to stir the mixture. The raisins will start to dance around and rise to the top of the glass. This is because the carbon dioxide in the soda is denser than the liquid, so it pushes the raisins up to the top. This experiment is a fun way to learn about density.

The Walking Water

This experiment is a great way to teach your kids about the properties of water. You will need two clear glasses, some food coloring, two paper towels, and some water. Start by adding a few drops of food coloring to each glass. Then, fill the glasses up with water. Place one paper towel in each glass, making sure that the ends are in the water. The water will start to move up the paper towel and will mix with the food coloring. This is because the water molecules are attracted to each other and are able to move up the paper towel. This experiment is a great way to show your kids how water moves.

The Bubble Snake

This experiment is a fun way to learn about air pressure. You will need a straw, some paper, a bowl, and some water. Start by cutting the straw in half and taping the two pieces together. Then, cut out a snake shape from the paper and tape it to the straw. Place the straw in the bowl of water and blow through the straw. This will create a stream of bubbles that looks like a snake. This is because the air pressure from your breath is pushing the water out of the straw. This experiment is a great way to show your kids how air pressure works.

The Candle Experiment

This experiment is a great way to teach your kids about combustion. You will need a candle, a jar, and some matches. Start by lighting the candle and placing it in the jar. Then, light a match and drop it into the jar. The candle will go out, because the oxygen in the jar is being used up. This is because the flame from the match is burning the oxygen, which is needed for the candle to burn. This experiment is a great way to show your kids how combustion works.

The Marshmallow Experiment

This experiment is a great way to teach your kids about gas. You will need a bowl, some marshmallows, and some water. Start by filling the bowl with water and placing the marshmallows in the water. Then, wait for a few minutes and watch what happens. The marshmallows will start to float to the top of the bowl. This is because the marshmallows contain a gas called carbon dioxide, which is lighter than water. This experiment is a great way to show your kids how gas works.

The Magic Milk Experiment

This experiment is a fun way to teach your kids about chemical reactions. You will need a bowl, some milk, food coloring, and some dish soap. Start by pouring the milk into the bowl and adding a few drops of food coloring. Then, use a dropper or spoon to add a few drops of dish soap. The milk will start to swirl and change colors. This is because the dish soap breaks down the fat molecules in the milk, which causes a reaction with the food coloring. This experiment is a great way to show your kids how chemical reactions work.

Conclusion

These simple science experiments are a great way to introduce your kids to the world of science. Not only will they have fun, but they will also learn something along the way. So, grab some supplies and start experimenting! Your kids will have a blast and learn a lot.
