Ordering Geologic Events using Cross-Sections

In order to give young scientists experience with critical thinking skills, introduce them to a current controversy and prepare them to debate. Choose a topic, such as genetically modified organisms, and assign groups to represent...

In this rock layers instructional activity, learners are given a diagram of various rock layers. They determine and list 14 events that occurred in order to form the rock layers in the diagram.

Epistasis originated from genetics but now applies to biochemistry, computational biology, and evolutionary biology. The video introduces epistasis as it relates to genetics. It also discusses dihybrid crosses, test crosses, polygenic...

Geology can be a lot of fun. Learners review geology related vocabulary, make flashcards, use encyclopedias to answer questions, then explore the formation of coal. They identify dates and order them into key time frames of geologic...

Students investigate radioactivity as a tool for measuring geologic time and how geologists use this information to determine the absolute age of rocks or minerals.

In this interactive tutorial you will explore how geologists use clues in rocks to determine the order in which rocks formed. Learn how principles of radioactivity are used to assign actual ages to rocks. Students will explore fossils...

Rocks may be created in layers, but those layers do not always stay in the form or location where they were created. Find out about the forces that can change rock layers that help tell the story of the Earth in that location.

Cartoon children compare the earth's age to timescales that we understand:a calendar year, the thickness of a book, the human lifespan. This smart film clip is definitely worth adding to your geologic timescale lesson! If you subscribe...

Get your young scientists excited about geology through the study of dinosaur tracks! They will use their power of observation to learn how tracks are made and use critical thinking strategies to suggest a scenario in which they were...

Connect earth science to science occupations and real-life events with this activity and activity. After listing the 4 branches of earth science, learners spend some time brainstorming two activities each type of earth scientist might...
