She currently teaches chemistry at Waterloo School of Austin. dishwasher liquid or powder. Use the litmus paper to determine which are acids and which are bases. Follow these instructions to make an egg bounce while learning about chemical reactions. When bases and acids are added together, they will neutralise each other’s properties. Run a bath, hop in and drop a bomb. You can also make your own pH indicator—use a blender to mix one part chopped red cabbage with two parts boiling water and use the juice to test different solutions. When you get a common cold, an infection in your upper respiratory tract, your body produces loads more mucus than normal to carry away waste material. >> Check out our project video to see this trick in action! Here are 8 hands on science experiments for kids over the school holiday. In this case, when you mixed an acidic solution (vinegar) with a basic one (sodium carbonate), the indicator made a colorful spectrum — from dark blue to red. These experiments are great for older children, or with assistance from Mum or Dad. This means that both gases and liquids are fluids. Shake the bottle for a few minutes until the water becomes a deep purple colour. This should be almost impossible. When sick, your mucus can change colour to yellow or green because of trapped bacteria, virus particles and white blood cells – the causalities of your body fighting the viral or bacterial infection. When a pressure is applied to slime, its viscosity increases and the cornflour slime becomes thicker. As the solution cools back down to room temperature, there is now more solute in the water than would normally be the case – the solution is ‘supersaturated’. The interactions between atoms in the fluids are so complicated that even the world’s most powerful supercomputers can not model what is happening. 8 simple chemistry experiments that your kids can do at home, Making sense of mathematics through reasoning, 6 Teacher-Tips for Making Learning Stick in the Classroom, How to Teach Addition with Regrouping | Super Easy Popsicle Stick Strategy.

An envelope. This will make about one or two bath bombs (depending on the size of the holes in your muffin tray). You have just made a realistic model of your very own snot. Try Mentos or other sugar coated lollies.
