Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach the proper...

Springboard your fourth and fifth graders into the study geologic time. They will complete 7 activities to learn about geologic time and the topics most often associated with it: astronomy, creation, planet formation, volcanology,...

Students examine geologic time to scale. For this geologic time lesson, students create a time-scale metaphor that shows some of the Earth's important events. Students present their metaphor to the class.

In this geologic time scale worksheet, students are given a list of terms and eras which they use to complete a time scale. They classify organic and inorganic changes that took place in the Precambrian era, the Cenozoic era, the...

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.

This is a nice explanation of geologic time and Earth's major eras. Although this site is designed for younger students, it is mostly text with few images.

Climate change has happened throughout the history of the planet, and the video uses examples from continental drift to modern airplanes as measurable examples. It begins with how climate change will impact systems on the planet. Then it...
