What animals are best suited for moving around a rainforest, or a desert? Design your own animal species based on a particular habitat, focusing on the characteristics it will need for optimal movement. Great as a group lesson or...

What goes into a museum display? A secondary-level STEM project prompts groups to design a museum display for the Tech Museum of Innovation. They create an analogous, interactive model illustrating a science concept to complete the...

How large can a population become? The fifth installment of a nine-part unit teaches young ecologists about limiting factors that determine the carrying capacity of species in the Sonoran Desert. Here is a PowerPoint to help present this...

See how changes in initial populations and parameters affect a biological community. Individuals use a special software program to simulate a desert community with five species. They adjust initial populations to see how the community...

Wolves eat better when the bunny population increases, but how long does that last? A series of 12 biology lessons uses the sixth installment to explore the predator-prey relationship between bunny and wolf populations. Young scientists...

How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

Cells demonstrate a life cycle like other living things, but what if death was no longer part of the cycle? Learn about the important balance requiring death to continue functioning. An online interactive introduces a group of scientists...

In this biology instructional activity, students complete a crossword puzzle with 35 questions about reptiles. They identify the different types of reptiles.

In this biology learning exercise, students answer 14 questions related to the skeletal system using an interactive crossword puzzle.

Third graders identify bones, muscles and joints. They explore and investigate the interaction between bones, muscles and joints, and movement of the hand or foot. To help the teacher provides a poster of the human skeleton.

Students organize data collected from their experiments using graphs. In this statistics and biology lesson, students organize their scientific data from an article into readable graphs. They define the usefulness of their graph and...

For this online interactive biology crossword puzzle worksheet, students use the 4 clues regarding cell structure to find the appropriate answers to complete the word puzzle.

Students describe features of cold seep communities and investigate five organisms that live there.  In this biological organisms lesson students research a given species and give an oral presentation on their results. 

Students explore biology by researching living cells. In this living organism lesson, students participate in a role-playing activity in which all the students in class form one plant cell by portraying specific parts of a cell. Students...

Second graders explore biology by dissecting an animal. For this squid anatomy lesson, 2nd graders collaborate in pairs to investigate the inner body systems of a recently deceased squid. Students utilize plastic knives to cut the squid...

Students simulate the interactions between a predator population of lynx and a prey population of rabbits. They collect and graph the data, then extend the graph to predict the populations for several more generations.

In this online interactive ESL worksheet, students respond to 18 fill in the blank questions regarding the phrasing of questions. Students check their answers immediately.
