Making an electromagnet at home is fun and easy. Most magnets, like the ones on many refrigerators, cannot be turned off; they are called permanent magnets. This one can be and is therefor called an electromagnet. They run on electricity and are only magnetic when the electricity is flowing. The electricity flowing through the wire arranges the molecules in the nail so that they are attracted to certain metals.
Can you and the kiddos solve the mysterious case of the disappearing egg shell? Following the simple how-to at Go Science Girls, you’ll learn the step-by-step and talking points about the process along the way. Warning! Although it’s totally non-toxic, toddler aged kids will be tempted to squeeze the egg at the end so make sure it’s a supervised experiment. Visit Go Science Girls to get cracking!
Step Four: Suspend the pit over a glass filled with water. The toothpicks will rest on the rim of the glass and hold the pit in place so it doesn’t sink to the bottom. Always check the water level in the glass and see that the water is covering the fat base of the pit by about an inch depth. If the water is below that level you’ll need to add some more.
Ah, slime. It’s the one thing that parents across the UK have been being pestered to make, so why not turn it into a science activity? For our concoction, we mixed shaving foam, PVA glue and a little bit of air freshener (fabric conditioner can work too!), to create a slime that you can swirl, stretch and crack, providing hours of fun. Try changing the quantities to see how the mixture changes, and ask the kids to explain the differences.
Invisible inks either react with another chemical to become visible or else weaken the structure of the paper so the message appears if you hold it over a heat source. But we're not talking about fire here. The heat of a normal light bulb is all that's required to darken the lettering. This baking soda recipe is nice because if you don't want to use a light bulb to reveal the message, you can just swab the paper with grape juice instead.
Learn interesting science and technology facts by experimenting with different materials that react in surprising ways. You'll find a lot of experiments can be done using simple ingredients found around your house (with adult supervision of course). Basic materials can help you perform experiments that are simple, safe and perfect for kids. Enjoy our fun science experiments, make cool projects with easy ideas for children, show friends & family what you've discovered and most importantly, have fun!
In this quick and fun science experiment, kids will mix water, oil, food coloring, and antacid tablets to create their own (temporary) lava lamp. Oil and water don’t mix easily, and the antacid tablets will cause the oil to form little globules that are dyed by the food coloring. Just add the ingredients together and you’ll end up with a homemade lava lamp!
Don’t be crodsquinkled, as these dream potion experiments are the best way to bring the bizarrely brilliant world of the BFG to life. These easy to make concoctions will whizz, fizz and pop before your eyes, creating exciting chemical reactions that will have all kids squealing with delight. Again made using things you’ll find at home or can pick up from the supermarket, this is an easy project to try with the kids. Be warned though - this is one of the messiest science experiments for kids on the list!
OST experiences also promote an appreciation for, and interest in, the pursuit of STEM in school and in daily life. They help learners understand the daily relevance of science to their lives, the depth and breadth of science as a field of inquiry, and what it might be like to choose to do science in the world, either as a professional or a citizen scientist.
Red cabbage powder (0.25oz/7g), citric acid (2oz/59ml), baking soda (2oz/59ml), 3 color tablets, cross-linked polyacrylamide co-polymer (0.5oz/14g), vegetable oil (2oz/59ml), corn starch (2oz/59ml), paper, 2 cotton swabs, 3 test tubes with caps, test tube stand, 3 plastic cups, pipette, stir 2 sticks, small and medium plastic measuring scoops and activity guide.
This solar energy science experiment will teach kids about solar energy and how different colors absorb different amounts of energy. In a sunny spot outside, place six colored pieces of paper next to each other, and place an ice cube in the middle of each paper. Then, observe how quickly each of the ice cubes melt. The ice cube on the black piece of paper will melt fastest since black absorbs the most light (all the light ray colors), while the ice cube on the white paper will melt slowest since white absorbs the least light (it instead reflects light). You can then explain why certain colors look the way they do. (Colors besides black and white absorb all light except for the one ray color they reflect; this is the color they appear to us.)
