Today in class you went over your balloon observations - qualitative and quantitative. Fun eh? You also learned a new concept - Inference - making sense of the observations; an explanation of what that observation means. For example, you saw bubbles as soon as you mixed the vinegar and baking soda. From that you would infer that a chemical reaction is happening and a gas is being produced. Get it? Start working on your observation/inference experiments this week at home. They are due Friday for class C and E. Monday for classes B,D,F.
Practice precision in measuring by visiting the following website and working through it. You need to scroll toward the bottom of the site to reach the interactive measurement slides. See how well you can do. Click here for the Interactive Meausurement Website
If you finish that, put in your ear buds and watch Bill Nye's clip on measurement
