This kit can be highly motivational to students for regular class or independent study. Both teacher and student guides are professionally produced and include easy-to-follow directions. Illustrations identify skulls of common prey species and charts are provided for students to record the data collected. Students learn about energy transfer through food chains while observing skeletal features which identify prey animals consumed. Additional studies can be conducted to evaluate animal populations within the owl's habitat, make calculations to estimate the biomass of the prey animals, or investigate the skeletal anatomy from the taxonomic features of the prey animals. 15 student worksheets, and Teacher's guide. Grades 7 and up.

Push the cart and eject the steel ball from the spring-loaded barrel. The ball falls back into the barrel of the moving car, demonstrating that the forward motion of the ball is the same as the vehicle from which it was ejected. Comes with a steel ball, release pin and cord. The barrel permits two different heights of ball flight.

When is a bicycle wheel a gyroscope? When you put a new "spin" on it. Give our bicycle wheel a spin, then try to tilt or deflect it. Our student-sized bicycle wheel turns freely on its axis and has large, comfortable handles at each end. Because mass is concentrated at the rim, you can tilt the spinning wheel to feel the force of rotation. With instructions.
