Science experiments are a great way for 11 year olds to not only learn about the world around them but also to have some fun too. With the right materials, and the right guidance, any 11 year old can conduct a range of science experiments that are not only educational, but also very interesting and enjoyable. Here are a few ideas for some great science experiments that 11 year olds can do.

Create a Volcano

Creating a volcano is a classic science experiment that is always a hit with 11 year olds. To do this experiment, you will need some clay, an empty plastic bottle, a tablespoon of baking soda, a tablespoon of dishwashing liquid, some red food coloring and some vinegar. To create the volcano, shape the clay into a mountain shape and place it around the bottle. Then mix the baking soda and dishwashing liquid together and pour it into the bottle. Add a few drops of red food coloring and then slowly pour the vinegar into the bottle. This will cause a reaction that will make the mixture fizz and bubble, and the ‘lava’ will run down the mountain like a real volcano.

Build a Water Filter

Building a water filter is an excellent way for 11 year olds to experiment with filtration. To do this experiment, you will need two plastic cups, a piece of cloth, a paper towel, some cotton wool, some activated charcoal, some sand and some gravel. Place the cloth into the first cup, followed by the paper towel, cotton wool, activated charcoal, sand and gravel. Then slowly pour water into the top cup. The liquid will filter through the cloth and other materials, removing any dirt or impurities, and then collect in the bottom cup.

Make a Simulated Cloud

Making a simulated cloud is a great way to explore the principles of evaporation and condensation. To do this experiment, you will need a shallow tray, hot water, ice cubes, and a piece of cloth. Place the tray on a flat surface and then pour the hot water into it. Place the ice cubes onto the cloth and then place the cloth onto the tray. As the hot water evaporates, the water vapor will rise and then condense onto the cloth, forming a simulated cloud.

Grow a Crystal

Growing a crystal is a fun and simple experiment that 11 year olds can do. To do this experiment, you will need some alum powder, a glass jar, some string and some water. Start by pouring the alum powder into the jar and then fill it with water. Tie the string to something that can fit inside the jar and then suspend it in the water. Place the jar in a cool, dark place and leave it for a few days. The alum powder will slowly crystalize and form a crystal shape around the string.

Create Slime

Creating slime is an easy and fun experiment that 11 year olds can do. To do this experiment, you will need some white glue, some water, some food coloring, some borax powder and some warm water. Start by mixing the white glue and water together in a bowl. Add a few drops of food coloring to the mixture and mix it in. Then mix the borax powder and warm water together in a separate bowl. Slowly add the borax mixture to the glue mixture and mix until it forms a slime-like consistency.

Grow Bacteria

Growing bacteria is an interesting experiment that 11 year olds can do. To do this experiment, you will need a petri dish, some nutrient agar, a cotton swab, a sterilized knife and some household items. Start by pouring the nutrient agar into the petri dish. Then use the sterilized knife to cut a few items from around the house, such as a piece of fruit or a piece of cloth. Rub the cotton swab onto the items and then rub it onto the nutrient agar. Put the lid on the petri dish and then place it in a warm, dark place. The bacteria will start to grow, and you will be able to see the results in a few days.

Grow a Plant Inside a Plastic Bag

Growing a plant inside a plastic bag is an easy and fun experiment that 11 year olds can do. To do this experiment, you will need a plastic bag, some potting soil, a small plant, and some water. Start by filling the bag with potting soil and then place the plant in the center of the bag. Add a few drops of water and then seal the bag. Place the bag in a sunny spot and then water the plant every few days. The plant should start to grow and you can watch the process through the plastic bag.

Make Your Own Battery

Making your own battery is an intriguing experiment that 11 year olds can do. To do this experiment, you will need a lemon, some copper coins, some galvanized nails, and some electrical tape. Start by cutting the lemon in half and then place the copper coins, galvanized nails and electrical tape into the lemon. Connect the copper coins and nails with the electrical tape and then plug in a small light bulb. The bulb should light up, proving that you have created your own battery.

Create a Lava Lamp

Creating a lava lamp is a fun and simple experiment that 11 year olds can do. To do this experiment, you will need a jar, some vegetable oil, some water, some food coloring and an Alka-Seltzer tablet. Start by filling the jar with equal parts of vegetable oil and water. Add a few drops of food coloring to the mixture and then drop an Alka-Seltzer tablet into the jar. As the tablet breaks down, it will cause the oil and water to separate and the food coloring will move around the jar, creating an effect similar to a real lava lamp.

Conclusion

These are just a few of the science experiments that 11 year olds can do. With the right materials and guidance, 11 year olds can conduct a range of exciting and educational experiments that are not only fun, but also very interesting and enjoyable. So why not give one of these science experiments a try today?
