Updated to reflect the current eight celestial planets. (Sorry Pluto!) Designed by AMEP's award winning Graphic Designer, this poster will bring a stunning representation of the Solar System to the classroom. Relative size and distance is explained along with a conversion scale of metric and US units. The number of moons, if any, are shown along with the astronomical symbol. This poster measures 45" x 18". Not laminated.

The digestive system is shown with details of the mouth, salivary glands, esophagus, stomach, liver, pancreas, and intestines. Learning is enhanced by the cutaway sections and enlargements of the stomach and intestines which further illustrate the system. Each model in the series contains the supplemental materials listed in the description of the general Human body System Model Activity Sets at the top of the page.

This book is an effective visual introduction to geology. Aerial photographs of geologically significant locations have been digitally transformed into fascinating 3-D views. There are sixteen aerial images included in this 3-D book vividly illustrating dozens of landforms typically covered by earth science textbooks such as mesas, landslides, faults, dunes, and volcanoes. A description of the location and a series of study questions accompany each photograph. Two pairs of 3-D glasses are included with each book.

Conduct the classic free-fall experiment with your class! A great improvement over classic free fall equipment, our Digital Photo gate Free Fall Apparatus retains the precision of older models while eliminating the hassle of setting up and adjusting heavy equipment. The apparatus consists of a lightweight extruded vertical column that carries a release electromagnet, two adjustable photogates, and a catching bag. The falling body is a 1.8cm steel ball. We recommend using it in conjunction with our Digital Timer 7-2009, which has several operating modes that allow different series of up to ten measurements to be made. These include: the time of fall from rest to the first photogate, the time of fall between the two photogates, and the time to pass through each photo gate. After conclusion of a series, the measured times are displayed successively. The data allows a precise determination of gravitational acceleration. 49" x 5" x 5"; 6.5 lb.
