Surface tension

Last week for science lab, Bronwyn's mom came in and did a lesson about surface tension. Did you ever wonder how a water bug walks across the water? Surface tension! 
The first experiment involved pepper sprinkled into a cup of water. What happens if you dip your fingers into the pepper and water? Now, add a squirt of dish soap. What happens now? Ask your child what the results were!







For the next part, each partnership had a pie plate with milk in it, and we squirted 4 squirts of food coloring, one color in each corner. We then added a squirt of dish soap in the middle of the plate- what happened?
