Science Week

Last week was Science Week in our house.
Monday: We did a couple of baking soda and vinegar experiments. First the kids poured a spoonful of vinegar into baking soda and watched it bubble. Then they did the "dancing raisin" experiment--water, raisin, baking soda and vinegar. The raisin forms bubbles around it, the bubbles make the raisin more buoyant, it floats to the top, the bubbles pop, the raisin sinks, and the process repeats. Remy hasn't learned how to follow directions yet. He grabbed a handful of raisins for his jar, tried to eat them, and dumped the jar out.

Waiting for the raisins to dance.

Tuesday: Jackson was at the office with Barry and Remy was napping, so Raina and I did a "Sink or Float" experiment. We gathered 20 objects around the house, filled a big bowl with water, and tested them. Raina kept track, and we had 13 float and 7 sink.

A rock sinks.

My little scientist.

Raina tallies the results.

Wednesday: We made oobleck. Mix 1 1/2 cups cornstarch and 1 cup water. Food coloring is optional. This makes a substance that is both liquid and solid. You could feel in the bottom of the bowl like it was wet sand, but when you pick it up in your hand it does not hold shape, but acts like a liquid. The kids had fun playing with it and made quite a mess!

Mixing up the oobleck.

Remy squishes it in his hands.

Jackson is not sure he wants to touch it.

Thursday: We went grocery shopping and did not do any science.

Friday: I was babysitting a little girl for the day, so we did not do any science.
Saturday: We were doing other things around the house and at the office, so we did not do any science.
Sunday: We did the Mentos/Diet Coke experiement. I threaded a small pack of Mentos onto a large paper clip and Jackson dropped it into the Diet Coke. We all watched it fountain out of the bottle! I'll try get the video posted soon.

Monday: Finishing science with a nature walk this morning, then the kids will make an art project with the things they find on our walk, transitioning us into Art Week!
