Geologic Age

Four activities demonstrate the chain reaction of nuclear fission to your physical science fans: falling dominoes, snapping mouse traps, throwing paper wads, and igniting a series of matches. They perform additional laboratory activities...

Take young geologists on an exploration of the rock cycle with this six-lesson earth science unit on rocks and minerals. Through a series of discussions, demonstrations, and hands-on investigations your class will learn about the...

Rock out with the second installment of a five-part series on earth materials and processes. Your budding geologists make observations of given rock samples and posit classification systems for rocks. They then learn about the accepted...

Rocks can bend? Pupils investigate how heat and pressure produce metamorphic rocks by modeling them using clay, and then categorize samples based on observable characteristics. The lesson ends with a metamorphic rock identification...

How much information can we process? How much information is stored inside us? These questions, and many more, inspired an inquisitive installment from a larger video series. From verbal and written language to DNA and computers,...

Dynamic music pumps up viewers as they learn about intrusive and extrusive igneous rocks. Presentation slides include a graphic depiction of magma below Earth's surface , photographs of lava exploding and flowing, and close-ups of...

Peer review of science laboratory reports? You bet! First, learners work in pairs to review a scientific article. Then they trade lab reports for peer review. The end result is the publication of a classroom scientific journal!

Fascinating photos of sedimentary rocks and formations supply a brief overview for your geology class. By viewing these slides, learners discover that sedimentary rocks are made of tiny bits of rock, dirt, or shell that have settled,...

Photographs of magnificent metamorphic rock formations make up the bulk of this brief slide show. Along with the upbeat background music, slow-moving slides, and informational captions of the slide show, you will also find key...

Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...
