Here are the trays ready for our Monday morningscience center. All the various experiments lead towards the final M&M;color mixing experiment. There were about four differentmini-experiments leading up to that. I’ll talk about thatmore in the next posting.

Experiment 1:Add a teaspoonful of sugar to water. Stir. Observe. What happens when you add sugar to water? What happens when you add several more teaspoons? Experiment 2:Cut (or bite) an M&M; in half. What do you see? We talked about the three layers —the outer layer which was coloreda small thin layer of white (more of the sugar-outer coating)chocolate Experiment 3: Pour water into a white screw top lid....

Experiment 4: (above) Take drops of food dye/water and drop two colors ontoa piece of coffee filter. What happens when the followingcolors mix?red-yellowblue-redblue-green, etc. Experiment 5: (below) Pour water into a white screw top lid. Add four M&Ms;,one each of red, yellow, green and blue. Make a prediction. What do you think will happen whenthe colors meet? Observe. **When the colors meet, they will form a solid line (atleast at...

I never got a chance to post about our science center experiment last week. We planted seeds in various ways. 1) We put seeds on damp paper towels and hung them in the window. 2) We put sprout seeds in a jar on the dining room table. 3) We planted seeds in soil in jars (covered with glad-wrap to trap the moisture). 4) And, we planted some seeds in the...

We had the quickest results with the seedlings in the window.  Overall, we had a lot to talk about because the seeds on the kitchen table started to sprout — and then died when they weren’t kept moist (we went camping this weekend). And the seeds at the bottom of the bags in the window didn’t sprout because they were submerged in water. That led to some good talks about...
