Teaching Science with Technology

This week we discussed using technology in teaching science to elementary school students. We began by looking at all of the different strands of science taught in elementary schools within the four main science branches. We looked at various scientific processes and how technology can help explain things and make them more "hand-on" for students to see.
We looked at CameraScope, a free UVA program used to hook up to a digital camera, webcame, or digital microscope to record data at different speeds. We saw how this technology allows students to study things that are too small, too slow, or too fast to examine with the naked eye. Some examples were looking at clouds, plant growth and movement, blinking, a firecracker exploding, and amoeba.
We also examined Gizmos on Explore Learning. These are simluations students and teachers can use to explore various aspects of science that they may not normally be able to create or touch. An example was looking at how viruses spread and infect cells in a simulation. Another was using many kinds of pulleys in class, which many teachers will not be able to set up.
We also spent some time examining our assistive technology assignments and discussing lesson planning with these topics.

The topics from this class will easily be used in elementary classrooms. First of all, these tools would be great ways to introduce topics in science that are difficult to examine by eye alone. I think it would be great to use a tool like CameraScope to slow down or speed up things like cloud movement, plan movement, and objects at a cellular level.
The Gizmos would also be great for similar reasons. There are topics in science that students often learn without seeing or examining closely. Using this site will give students the feeling of studying science in a more hands-on fashion than normal.

The question I have from this week is if there are certain sites that are good for finding videos like the clouds or plant we saw in class without having to film them all ourselves. Are there resources that are reliable for finding tools like this to use in class. Is there any Fair Use that comes into play with things like this?
