Leaf Classification Guide

Send your young life scientists on a plant webquest that has them reading case studies to decide if seeds are seeds and plants are plants. 

Junior biologists journey through the hiearchy of living things with these activites. Using a dichotomous key, they identify common algae, plants, and fish. They design their own key for a mixture of seeds and a collection of...

Let your knowledge grow like weeds. The second installment of a four-part series teaches pupils about weeds, their classifications, and their characteristics. An investigation into weeds has the class finding, collecting, drawing, and...

The three types of rock aren't classic, punk, and hard. The chapter covers everything scholars need to know about rocks. Pupils compare rocks, learn about their formation, see how rocks change, and follow every step of the rock cycle....

Students compare and contrast classification systems used throughout the world. They also examine the importance of preserving biological diversity.

In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

Electronic field guides are so handy, and with this one, field biologists can identify common North American trees by looking at their leaves, fruit, or flowers.

Students examine classification of trees through their leaves, and use on-line field guides to identify leaves.
