Students study how Alzheimer's affects different parts of the brain, sketch a healthy neuron and its parts, and diagram brain changes during the early and late stages of Alzheimer's.

In this unit, the students explore basic ecology concepts and scientific processes using spiders as model organisms. They capture spiders, observe and care for them, and use them to answer their own questions about spider behavior....

Seventh graders explore the connection between genetics and heredity by examining the cellular structure. Among the numerous activities to engage students are drawing DNA molecules, vocabulary puzzle sheets, and predicting possible...

How is an animal formed? Scientists use a diagram to examine early post-fertilization stages, and the creation of the blastula. They look at a second diagram to observe the transition from the blastula to a gastrula. Three comprehension...

Students begin by using clay to model fertilization and early development of sea urchins and chordates. They move on to mixing live sea urchin sperm and ova together to observe, diagram and record events occurring in fertilization and...

First graders study seeds. For this biology lesson, 1st graders observe the differences between dry and wet seeds and draw what is inside a seed after peeling off the outer coat of one of the seeds.

Can your class correctly classify plant species? Individuals explore native plants of the local environment and correctly classify them into their respective categories. They investigate differences in the plants and discuss similarities...

Students examine the early development of zebrafish as a model for embryo development in humans. They observe various stages of zebrafish reproduction from sperm and eggs to fertilized eggs and hatchlings.

In groups, learners read a case study of a couple who produced a child with hemophilia. Although tthe reading breifly mentions how a hemophiliac child is produced, the focus of this instructional activity is the ethical implications....

Explore 1870s when a "bone rush" led to amazing discoveries, as fossil-hunters risked life and limb in their quest for dinosaur remains. The class uses the attached visual encyclopedia to prep for a discussion on early paleontology. Two...

Biology learners will be able to explain the binomial nomenclature system and name the seven levels of classification of living things after viewing this set of slides. Brightly colored with bold fonts, the format is eye-catching, and...

Students gather mosquito eggs to record the mosquito life cycle using drawings, descriptions, and any other appropriate means. In small groups, they analyze and describe the process of complete metamorphosis. They classify mosquitoes...

For this biology worksheet, high schoolers look for the words that are part of the word search puzzle that is focused around the theme of the sheet embryology.

Students compare characteristics of animals and human beings. In this biology lesson, students observe an animal and record their observations. They infer whether the evolution theory is true or not.

Students identify the different parts of the cells and their functions. In this biology lesson, students create an analogy of a cell and its organelles. They make a poster and present it to class.

Students identify the components needed by plants to survive in the terrarium. In this biology lesson, students build their own terrariums using materials available. They present their project in class.

Gain skills in ecosystem evaluation including chemical, biological, and physical qualities. Students write a report on a local ecosystem.

Students get a look into the life of dogs-from their origins and basic biology, through selective breeding, and into how dogs have become intricate parts of everyday life for many people worldwide.

Learners 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. Learners create drawings as they...

Learners explore butterfly life cycles and movement.  In this integrated fine arts and biology life cycle instructional activity, students listen to the book The Very Hungry Caterpillar by Eric Carle and identify the related life...

Students observe embryogenesis in action through early stages of development of eggs. They observe cultures with dissecting and compound microscopes. They draw their egg, record any details and observe for changes. They compare their...

In this Earth's history worksheet, students 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. Students will complete 4 short answer...

Five pages take biologists on a generalized survey of the origin of life. Queries are made regarding theories of how life developed, ancient Earth conditions, and the ever-changing field of taxonomy. The experiments of different...

Students investigate the brain through multiple senses. In this biology lesson, students experiment with different activities involving taste, memory, touch, and sight to understand how the brain works. Students work in partners and...
