Ginkgo trees existed for more than 350 million years, and, at this time, only one species still remains. While plant diversity generally increases over geologic time, some interesting exceptions occur. Young scientists learn about plant...

In this fossils worksheet, students create their own casts, molds, imprints, and embedded fossils. Then students complete a fossil comparison chart. This worksheet has 12 fill in the blank questions.

Students examine the geological time scale: the Earth is ancient; time can be divided into periods based on its fossil content.

Students research the four geologic eras of Earth's history. In this extension on a fossils lesson plan, students research the different eras of Earth's history. Students use AppleWorks to create a bar graph containing information of the...

Students actively engage in the careful analysis of chromosome banding patterns and identify examples of inversion in homologous chromosomes.

Students work in groups as they read chapters of Charles Darwin's, Voyage of the Beagle. They take notes on the chapter and in their group make a timeline of the chapter. They tape the timelines together in order to depict the entire...

Tenth graders are introduced to the topic of evolution. Using the internet, they discuss Charles Darwin's life and work in this field of science. They examine fossils and discuss how they support the theory of evolution. They participate...

Seventh graders investigate the concept of evolution and how it was a mechanism for the foundation of life on Earth. They conduct research and attempt to make cognitive connections with the evidence to agree with the presupposition of...

Learners examine fossils and analyzing their significance in relation to theories of evolution. Hand-outs are provided. This lesson could be supplementary to a broader unit on evolution or geology.

Students complete an online activity in which they examine fossils to find possible hominid family trees.

Learners are introduced to four important fossil finds: the First Family, the Hadar Skull, Lucy, and the Laetoli Footprints. They explore how scientists interpret fossils to try to better comprehend how humans evolved. This activity...

Students recognize that they haven't seen a dinosaur because they no longer exist. In this dinosaur lesson, students view videos and understand what the dinosaur habitat was like. Students role play dinosaurs. Students explore dinosaur...

In this Earth's history worksheet, learners will complete 5 true or false questions based on the early history of the Earth. Students will match 7 fossil vocabulary words to their definitions. Learners will complete 4 short answer...

Students build a realistic sense of geological time, seek clues of transition fossils and find them.  In this investigative lesson students complete several activities and worksheets on fossils. 

In this earth history worksheet, students visit a website and complete 15 fill in the blank and 8 short answer questions based on what they read. Topics include biodiversity, animal kingdoms, evolution, fossils, and extinction.

Students discuss the discovery of a transitional animal, Tiktaalik, and its impact on the theory of evolution. They research theories of evolution and creationism.

Young scholars examine mechanisms behind biological evolution and the theories that feed it, and are able to demonstrate their knowledge of these theories in a story.

Can you imagine Washington DC and London as close neighbors occupying the same continent? Learners will be fascinated as they step back in time and discover the evolution of the earth's continents and oceans from 4.5 billion...

Learners experience, through a "dig," the historical discovery of fossils which increasingly link whales to earlier land-dwelling mammals. They encounter the intermediate forms which show changes that lead to the modern whale.

Students examine how the method of classification is used. In this sorting lesson students take a pre-test, classify organisms and complete a crossword puzzle.

In this primate evolution worksheet, students will review the structures and functions that are characteristic of primates. Students will identify the differences between Old World monkeys, New World monkeys, and prosimians. This...

For this earth history worksheet, students answer 12 questions about geological time, the eras of Earth, the changes taking place in early Earth and the life present during the eras. They also answer 2 questions about the Paleozoic Era.

Human bodies prove evolution thanks to our genes, bones, and more. Learning about specific body parts and how they evolved from other species helps individuals better understand the transition species that helped us become who we are today.

Octopodes existed for hundreds of thousands of years before humans, yet our eyes share many similarities. Scholars analyze the evidence to determine if the evolution of eyes best fits a homology or analogy model. They discuss the issue...
