Ed Tech 4 Science

When it comes to science supplies, you can be sure that measuring devices such as stop watches, scales, rulers, and graduated cylinders will be useful. There is risk however in purchasing other materials, as you wonder will they work.

It all started well with my Sprout and Grow Window kits that I purchased for my elementary sciencemethods classes. They planted the generous supply of pea plant seeds that the kit provided. And in 5 of the 6 windows we had healthy germination. The plants looked neat growing up out of the thin plastic container housing the roots.

But the window idea paid no dividends. Although it was possible to see some small roots amid the very dark soil, it was disappointing how little you could actually see. I took one of the kits home to care for the plants. About one week after we started the kits, I planted the same pea plants in my home garden. Last week I took pictures of pea plants in the kit and in my garden. Our home telephone is put into each picture for scale.

I know this is not a carefully controlled experiment. Nevertheless, clearly the outdoor garden plants did much better than the window indoor plants. Most people would guess that would be the case, even in a “winter” in Phoenix (where we have so far managed to avoid a seriously deadly frost). But without the benefit of being able to view the roots well, you have to wonder, why would you want to use the Sprout and Grow Window kits? So this review, gives these kits a rating of only 1 out of 4 test tubes. In other words, I don’t recommend that you purchase the product.

But it is nice that the pea plants they supplied grew so well outdoors. I have never grown peas before and I must confess I felt a connection to Gregor Mendel as I saw my plants rise up and flower. I even have pea pods starting to form. I think I will hold off on any genetic crosses for the time being but I think I might be up for a virtual experience at Adaptive Curriculum’s “Mendel’s Experiment.”
