This week we decided to have one science day instead of trying to fit the week 10 experiments into our already busy days. So on Wednesday we did fairly quick math and language arts lessons and then devoted the rest of the day to "Science in the Kitchen".
The first couple of experiments were from the 'Soaked Through' lessons and dealt with absorption. Since Sydney is a 4th grader, we took some time talking about the scientific method and made sure to take good notes about our experiments. We aren't using the correct vocabulary for the method at this point. I'm more concerned with her learning the steps of scientific observation and testing and then later we'll go back and learn how to take "proper" notes for our experiments. We talked about ways to set up charts to record our results and how to form a hypothesis and write a conclusion.
In our first experiment, we tested to see how well various objects soaked up a set amount of water. We discussed how to make the test "fair" - by using the same-sized materials, the same amount of water and drying the wet surface after each trial. We went over our procedure several times to make certain that we would not make any mistakes. Then we recorded our
guesses, performed the experiment, recorded the test results, discussed and then reached our conclusion: Thicker, porous materials will soak up more water than thinner, porous products because there is more area for the water to "stick" too.

Our second experiment was to see what would happen to dots of ink when soaked in water. The girls thought the first trial was uber cool....
Unfortunately Mommy forgot that we were using washable markers so the only result was that the ink washed right off the cut strips of coffee filters. Pretty? Yes. Informative? Not so much.
Take 2. This time we used permanent markers, but not all that much happened. However the girls did notice that the yellow was seeping out of the green dot. We'll try this experiment again. After I get better markers!
Our final experiment dealt with evaporation. We discussed the water cycle, how and why water forms on the bathroom mirror during a shower and talked about how dew forms on the grass. Then we took two dish towels and got them equally damp. We sealed one in a plastic bag and left the other out to air dry. The girls guessed which would dry the most and why and then we put them on the dryer until this afternoon.
Both girls correctly guessed that the towel left out of the bag would by the dryer of the two and even Delaney understood that the other one was still wet because the water had no where to go once it evaporated off the towel.
Ahhhhh. An excellent day of science.
