Science is not only a fascinating subject but also a great way to stimulate your kids’ curiosity, creativity, and critical thinking skills. As parents, you have the opportunity to make science come alive in your own home, and no worries, the experiments are completely safe and also fun. You can use some simple and safe materials that you probably already have in your kitchen, bathroom, or garage. Here are some examples of fun and safe experiments that you can try with your kids and learn some science concepts along the way. Learning can be fun, and I’m sure your kids will find it more fun because they will be doing these experiments with you.
Lava Lamp
The mesmerising effects of lava lamps are one of the major things that I find fascinating about them, and lucky enough, they are very easy and safe to make with your kids. You can make your own lava lamp at home using vegetable oil, baking soda, vinegar, and food coloring. This experiment teaches kids about density, which is how much mass an object has in a given volume. Oil is less dense than water, so it floats on top of it. Vinegar reacts with baking soda to produce carbon dioxide gas, which is lighter than water, so it rises to the top, bringing some colour with it.
Materials needed: a clean plastic bottle or glass jar, vegetable oil, baking soda, vinegar, food colouring, and a flashlight (optional).
Steps: Add a couple of inches of baking soda to the bottom of your bottle or jar, and then fill the rest of the bottle or jar up with vegetable oil until it is almost full. Use a funnel if you have one. Notice how the oil stays separate from the baking soda. In a separate cup, add about a fourth cup of vinegar and some drops of food coloring. Mix them together. You can now slowly pour the vinegar and food colouring solution into the bottle or jar with the oil and baking soda. Watch what happens! Also, if you have a flashlight, turn off the lights and shine it through your lava lamp to see it glow!
Slime
Making slime is one of the most popular and safe science experiments for kids because it is fun to play with and easy to make. There are many recipes for slime, but one of the best ones uses borax and school glue. This experiment teaches kids about polymers, which are long chains of molecules that can stretch and bend. Glue is made of polymers, but they are tangled and sticky. Borax acts as a cross-linker that connects the polymer chains together, making them slide past each other more easily and forming slime.
Materials needed: white school glue, borax, water, food colouring (optional), a large bowl, a small bowl, and a spoon.
Steps: In the large bowl, mix one cup of glue with one cup of water. Add some food colouring if you want to make coloured slime. In a small bowl, dissolve one teaspoon of borax in half a cup of warm water. Slowly pour the borax solution into the glue mixture and stir with the spoon. Then use your hands to knead the slime until it becomes smooth and stretchy. Have fun playing with your slime! You can store it in an airtight container or a zip-lock bag when you are done.
Baking Soda Volcano
You can make a classic science experiment by creating a volcano that erupts with baking soda and vinegar. This experiment teaches kids about chemical reactions and how gases are produced.
Materials needed: a small plastic bottle or a glass jar; a tray or a large plate; modelling clay or play dough; baking soda; vinegar; food colouring (optional); and dish soap (optional).
Steps: Place the bottle or jar on the tray or plate and cover it with modelling clay or play dough, leaving the opening uncovered. Shape it into a volcano-like cone. Then, add some food colouring and dish soap to the bottle or jar if you want to make coloured and bubbly lava. Add about two tablespoons of baking soda to the bottle or jar. After that, pour about half a cup of vinegar into the bottle or jar and watch your volcano erupt.
Dancing Raisins
Materials needed: clear glass, carbonated water, raisins.
Steps: Fill a clear glass with carbonated water. Drop a few raisins into the glass. Watch as the raisins dance and move up and down due to the carbon dioxide bubbles sticking to their surface and lifting them.
Oobleck Exploration
Materials needed: cornflour, water, food colouring (optional).
Steps: Mix cornflour and water in a bowl to create a substance known as oobleck. It’s a non-Newtonian fluid, meaning it behaves like both a liquid and a solid. Let your kids explore its unique properties by squeezing it, poking it, and even walking on it. You can add food colouring for added visual appeal.
Doing these fun and safe experiments with your kids will not only entertain them but also help them become more curious when it comes to learning. You can make learning an exciting adventure as a parent. Science experiments are a great way to have fun and learn with your kids. They can spark their interest in science and inspire them to ask questions, make observations, and discover new things. So, what are you waiting for? Grab some materials and start experimenting with your kids!
