Science in the Garden

I took 4 very excited children to Organic Garden and Feed in Denton yesterday. We are now fully outfitted with organic seeds, organic potting soil complete with bat guano and worm castings, lots of little trays with covered lids, and organic cloth containers. I am already in favor of the cloth containers as it is impossible to over-water. The extra water just drains out! This is great with my young watering enthusiasts.

We planted corn last night by the light of the moon and Lincoln's wind-up flashlight. He had to crank continually to keep the light going while Isaac, Stella, and Ava poked corn seeds into the pots. He was sweating so much by the time we were done, but he didn't care. The kids are extremely emotionally invested in the corn. I've never grown corn in a pot. I hope it works! They planted 4 corn seeds per 5 gallon pot with dreams of at least 2 corn plants surviving and producing.

Tonight we planted the rest of the seeds by a full moon and a desk lap. Isaac measured the depth and seed placing very precisely, while Stella documented the seeds with a seed map. Both are writing up full lab reports on their experiment, including all the special materials used, such as bat guano and worm castings. They are rather excited as this is the longest on-going experiment we have done so far. The results and conclusion will not be know for awhile.

Our biology studies started with Isaac, Lincoln, and Rob constructing our own compost bin. Kids read, researched, reported on how to build a compost bin and how to make organic dirt. Unfortunately, we haven't found worms yet, and so our compost has not turned into dirt yet, thus the purchase of the organic potting soil. The kids daily make trips out to the compost bin (aka a converted 5 gallon bucket) and roll it around to turn the material. Everyone, especially me, has been briefed as to what can go into the compost bin and what may not! Today the boys made a second compost bin out of a 5 gallon bucket since the first one was filled.

Isaac kept a sun journal today noting the position of the sun on the front porch. We decided that the backyard had better sun exposure for the plants.

The next building project is a rain barrel. The boys have the plans laid out already.

I sure hope the seeds sprout and produce! I have put off gardening for years until now. This is our biology year in our 4 year science rotation and the big kids are finally big enough to take charge while I keep Ava out of the way. Only in the name of science and education does this hold any appeal for me! I know it is a TON of work, but I am looking forward to some organic fresh produce.

All of this transpired after a full day of practicing, lunch, school, dinner, an after dinner run, and then finally the planting!

Next project: grow cucumbers year around indoors with a grow light! We go through one cucumber an afternoon during school as a snack. Kids are confident that we can grow our own...

The best part is that it is 80 degrees warm already in Texas and it is only March! We are going to try at least 3 different planting schedules to see how long we can keep the plants producing.

Science Saturday with Daddy

Beginning on January 1, 2011, Rob has taken over the role as lead science teacher. I provide the instructions, supplies, and materials while he supplies the direct teaching and experimenting direction. Usually I also keep Ava busy so that she does not purposely allow the specimens to escape. This year we are studying Biology and began with an experiment using rollie pollies, otherwise known as pill bugs. With the aid of our new Brock Magiscope, we investigated the rollie pollies up close and experimented to see if they preferred wet or dry surfaces, open or closed areas, and hot or cold temperatures.

Earth Science K/2nd grade

Homeschool Science
Isaac waits with apprehension and Stella waits with excitement for the baking soda/vinegar volcano to erupt. Isaac may have a career with OSHA in the future. He was SURE that we all needed to be at least 5 feet away from the "exploding" volcano. Only after much assurance would he come close to the table. After the first eruption, we had to continue until all the baking soda and vinegar were gone.

Stella and Isaac display their models of the earth's layers.

Science with Daddy! Everyone was amazed as we added vinegar to baking soda and watched the ballon expand! Lincoln is the class helper.

After reading about caves, we did a science experiment with epsom salts. We grew stalagtites from the string.
