... can tire their arms. Clear off the foam from the top of the bubble solution before using it as foam wrecks big bubbles. Make sure your hands are "wet" with bubble mix so they do not pop the bubbles ...
In this unit designed for Kindergarten teachers, children will participate in activities and learn about wet and dry materials. These experiments explore evaporation, textures, and different solutions. ...
... are made by linking hundreds of glucose molecules. The monomer glucose is sweet and dissolves easily in water but the polymer of starch is not sweet and forms a thick, sticky paste in solution. In this ...
Students see dissolved substances come out of prepared solution. Introduction The amount of salt that can dissolve in water depends on the temperature of the water. As water evaporates from a salt ...
Challenge your students to put a penny in a cup without touching it. Introduction The solution is to use inertia to your advantage by taking the playing card out of the way as quickly as possible. ...
... investigators can spray a luminol solution and in the dark the bloodstains will glow with blue light. Haemoglobin (found in our red blood cells) contains iron which reacts with the luminol like the copper ...
Students see colours change in a solution, and learn how chemistry can explain this magical result. Introduction This trick works because iodine is brown when dissolved in water and purple when ...
... In this magic trick, the phenolphthalein in beakers 1 and 3 will turn purple when you mix it with the ammonia in beakers 2 and 4. When you pour the two purple solutions into the large beaker, the acidic ...
Students create water filters then pour different degrees of dirty water through the filters and guess which solution will be filtered into the cleanest final solution. Introduction The ...
