In a semi-darkened classroom at Coronado High School, the recessed computer projector shined down upon a slightly cushioned floor. David Birchfield, politely told me, “We only walk on that after we take our shoes off.” So I quickly jumped off. Ms. Mills and her physics class came in, and the students sat in chairs around the perimeter of the square mat, almost as though they were there for a martial arts exhibition.

Then the physics began. There was a handmade object that when you pushed a button it dropped its bottom. It had reflective tape so the mini-cameras around the room could pick up its motion and transmit it to a computer, which interpreted the data and then created dots on the mat to show the motion of the large object or the separated objects.

A student spun around in a circle and then pushed the button. The bottom sphere dropped and fell away from the object. From the dot pattern it was quite clear, and one student even said it spontaneously: “It moved away at the tangent.” No longer would these students have the misconception that a moving object would still hold the circular force because of its prior motion. Indeed, from Newton’s first law, it was apparent the straight-line motion of the object.

Students took turns trying it. Then to keep them engaged in their free exploration, there were a number of challenges issued, starting with “Let’s aim at Justin.” Then they aimed at a fixed target. Then at a target moving the same direction they were spinning, with a student walking and holding the target, and then at a target moving in the opposite direction.

After the class was over, I tried it as well, this time sans shoes. I have experienced the future, and it is on the floor. There is more power in an experience that is whole body, rather than just fingers on a keyboard or a mouse. Watching the physics class, there is also the learner interactions that make this a potentially powerful learning environment. To be sure, we will see applications like this in museums before it makes it into regular classrooms. Because it can be used with many content areas, some schools might have a SMALLab (Situated Multimedia Arts Learning Lab) for all their teachers to share. And no doubt the 3-D tracking system can be brought to use with interactive white boards, making their use more economical.

My thanks goes to Arizona State University’s David Birchfield, Kelly Phillips, Tatyana Koziupa, Mina Johnson, and Leanna Archambault for letting me experience the future. This will be a tool that will help students overcome misconceptions and experience science in a different way.

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.”
