They shake the ground underfoot, causing tremors that, at their worst, can leave cracks in highways and topple buildings. But for the most part, earthquakes are constantly rumbling through the Earth with a force that's barely detectable. But why do they occur? In All About Earthquakes, children will examine the forces at work that cause earthquakes and discover the instruments that scientists use to predict and measure these earthly tremors. A visit to Mammoth Lakes in California showcases an advanced network of lasers that measures ground movement in the area, while a fun, hands-on activity demonstrates how architects test their designs by using a shaker table. Part of the Earth Science for Children DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.

Arthropods are animals that have an external skeleton. They are the most abundant animals on Earth but are often misunderstood. Spiders, millipedes, and other arthropods are often mistakenly referred to as “insects” and “bugs.” This poster explains the differences.
Each of the five clades (formerly subphylum) is carefully explored. Highly detailed illustrations show an incredible 98 species, many life size. All are identified by both common and scientific names.
Insects account for the great bulk of the arthropods, and this poster includes representatives of all the major orders. The crustaceans include crabs and lobsters as well as shrimp, krill, and even barnacles. Included with them is the giant sea scorpion; this long-extinct animal is the largest arthropod that ever lived, reaching a length of six feet.
This remarkable poster even includes the prehistoric trilobites. They were the dominant life form during the Permian but became extinct. Highly educational, very attractive, and decorative, this poster appeals to teachers, students, collectors, and professional entomologists.
