Sun-Powered Science Projects

Since we don't want to spend our golden years pouring gold into the pockets of Middle Eastern oil cartels and homegrown utility companies, we encourage science students to explore solar cells. Exposed to light, even these small modules will power DC motors, charge batteries, or run an eye-popping science project. 92481 is 2-9/16" x 3-5/8". All are enclosed and have leads.

Prehistoric Poster

So the poster is really brand new. The animals on it are (1) to (190) million years old, and if that doesn't qualify as pre-history, may we stumble over a glyptodon in the dark. Invicta Plastics Ltd. of Leicester, England, printed this 23" x 16-1/2" poster with a colorful diorama to promote their authentic scale models of prehistoric animals. A time line across the bottom lists dates and data for a dozen of them, from the plesiosaur to the woolly mammoth, and compares their sizes to that of a pair of five-year-old children. Post it on the fridge to spark supper discussions, or in the classroom as a source of extra-credit questions for science quizzes.
