Students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. They run a series of simulations varying allele frequency and population size and then analyze their...

Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.

Students discover that throughout history cities have been centers of population but that human exploitation of fossil fuels was key to the growth of large cities worldwide. They research urban growth through a number of websites.

Third graders explore the parts of a leaf and use a dichotomy key to identify leaves. In this biology instructional activity, learners study characteristics of various leaves and play a game of bingo to identify leaves by their traits....

Students discover the actual size and weight of many insects and animals. In this biology instructional activity, students investigate animals and insects to determine their actual weight and size. In groups, students create an animal or...

Eighth graders compare their local ecological zone to the tropical rainforest. For this natural ecology lesson, 8th graders complete an activity about the differences in ecological zones. They compare their biome to the Guatemalan...

Students acquire a general knowledge of fossils and paleontology, the study of evidence of life in the past and identify the major invertebrate groups (phyla) commonly found in the fossil record.

Students investigate the real world applications of nutrition. They study the problem of starvation and how it affects different populations. Students work in small groups in order to devise and intervention plan. They also search out...

Students examine the principles of electrophoresis. They evaluate both the agarose and polyacrylamide system of molecular separation. In order to bring the concepts of genetics and evolution full circle from DNA to protein, students...

Seventh graders, using national parks as models, illustrate the energy flow in ecosystems. Working in groups, they use murals, flow charts, or other visual displays to record their findings. Students represent the food chains and webs...

In this science worksheet, learners complete a series of puzzles related to the subject of plants. They complete a reading and apply the information to measure reading comprehension.

High schoolers identify auxins from their structural formulas. They understand the process of refluxing in chemical synthesis. Students perform thin layer chromatography using silica gel plates to differentiate chemical substances.

Students participate in a field study of Maine Black Bears. They first do academic research on the Maine Black Bear. Following extensive research and discussion, students go out into the field with Maine State Biologist to observe bears...

Students are introduced to the tropical rainforest through different ways that catch their attention such as: Visit a local botanical garden or conservatory so that students can see the variety of tropical plants in the world. They...

Students identify and describe five main groups of the Phylum Chordata. They discover that the Phylum Chordata is the vertebrates. Students identify the main difference between invertebrates and vertebrates. They read passages about...

Young scholars explore animals that live in trees. In this nature and biology lesson, students go outdoors and make observations about animals and their unique body parts that help them to live in trees. Young scholars create drawings as...

Young scholars describe the characteristics of an ecotone. For this ecotone lesson, students pick out their area and describe the visual appearance, conditions, ecosystem, biodiversity, predators, prey, and trees in their ecotone. They...

Second graders explore biology. In this life cycle lesson, 2nd graders act out the stages a caterpillar goes through to become a butterfly. They spend days prior to this lesson observing caterpillars they have collected and developing...

Students discuss biological diversity in ocean communities. In this diversity activity, students examine the variety of organisms compared to relative abundance. They will write an analysis and discuss their findings with the class.

Second graders create models, practice inquiry skills, work with fellow students in teams, and reinforce concepts discussed in class all by using the theme of BIOSPHERES.

Students grow duckweed, observe what happens when an organism population is allowed to grow without predation or competition, view videos about invasive species, and develop a proposal for controlling the growth of an invasive species in...

Students explore an exhibit through an interactive program on frogs. They can listen to the different sounds frogs make and the different types of frogs. They search for the types of frogs they find in their local area.

Students observe the changes seen in succession and the biodiversity of a community through its species richness and evenness. They create a dung culture in a clear plastic cup from horse, goat or cow dung then observe the numbers of...

Students explore the Sanger sequencing method which produces a nested set of radioactive fragments from a template strand. They simulate the Sanger method of sequencing DNA, both visually and kinesthetically.
