I often let dh take over the experiments needed for our children's schoolwork - except for the easiest things.
On Wednesday night he and ds1, age 15, did the second round of the microscope experiment looking for organisms that ds collected and then cultured. He was supposed to use pond water, and it may have worked better if he did, but as we couldn't think of a nearby pond he collected slow moving water from a nearby stream. The water was placed in 4 jars, and different things were placed in the jars to see if and how the organisms would reproduce within the different culture mediums. (I'm not sure if this is a case for "media".)
The first round was done last Sunday and there was some success. This Wednesday they also found a few things, I can't remember if they were found in the same cultures or if different jars came up winners this time. We all had a look (the youngest couldn't see anything) and it was quite exciting. Even ds admitted that it was!
What was really nice, and one of the benefits I see in homeschooling, was how my husband told the children that even in these single celled organisms the DNA was as complicated as in us, and pointed out how unlikely it was that macro-evolution could happen. He said a lot more than I could remember or repeat here, but it was wonderful that he could use that teaching moment to foster both an appreciation for what we were seeing, and for God's sovereignty and power in creation.
