For this magic milk experiment, partly fill a shallow dish with milk, then add a one drop of each food coloring color to different parts of the milk. The food coloring will mostly stay where you placed it. Next, carefully add one drop of dish soap to the middle of the milk. It’ll cause the food coloring to stream through the milk and away from the dish soap. This is because the dish soap breaks up the surface tension of the milk by dissolving the milk’s fat molecules.
If you do this sidewalk constellation craft, you’ll be able to see the Big Dipper and Orion’s Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.
It’s natural to have a lot of questions about the world. As you wonder about these things and ask questions, you are learning. Curiosity about science helps you become an explorer finding out how things work and why things happen. Anyone can be a scientist, performing experiments to ask questions and get answers. You can even be a scientist at home, working on experiments with ingredients you probably have in your kitchen or laundry room. Always get a parent’s permission before you conduct experiments. Working as a team with an adult is best for safety.
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.
