Are you a mother o father ( uncles and aunts are permitted) ? Do you want to spend some time with your children trying water experiments? 1.Drop a single drop of food coloring into a glass of water. Dont stir or shake. Just watch what happens. (Its called diffusion.) 2.Use a medicine dropper to drop water onto a penny, one drop at a time. How many drops will the penny hold before the water spills? (The answer may surprise you!) 3.Try the same water experiments as #2 with water that has a little detergent in it. 4.Try the same thing as #2 comparing the heads and tails. 5.A lump of clay sinks. Change its shape to make it float. 6.Dunk sieves and colanders in water. Pour water through funnels. What does the size of the holes have to do with how fast the water flows? 7.Compare the sizes of containers by filling one with water, then predicting whether another will hold more or less. Test your prediction. 8.Measure volumes of water using measuring cups and spoons. Weigh measured volumes of water on a diet scale. (Dont forget to subtract the weight of the cup that holds it). 9.Simulate erosion by pouring water onto a mountain of sand or dirt. Experiment to find out whether some soils resist erosion better than others. 10.Select some household objects. Predict which will sink and which will float. Test predictions at bath time.
