Before digital microscopes, scientists hired artists to draw the things visible in the microscope. Through training in neuroscience and art, Cajal revolutionized the way we view the beautiful brain. The third lesson in a series of four...

Roger Kornberg, the oldest son of two biochemists, won the 2006 Nobel Prize in Chemistry. Learn about Kornberg and his scientific research with an animation, videos, biography, and an applied problem-solving activity. A summary and...

Eighth graders review concepts in cellular biology. For this biology lesson, 8th graders play an interactive game based on the idea of winning money. They discuss misconceptions about the topic.

Learners record observations and create drawings and models of anatomy using their five senses. They describe the structures of a neuron and analyze each of their functions. They compare and contrast the typical structural features of a...

Provide young biologists with everything they need to excel in the study of lymphatics, the nervous system, hormones, cellular division, and more! Pupils utilize the workbook, complete with end-of-chapter assessment worksheets, to...

Students determine their inherited characteristics from their parents. In this biology lesson, students study the life of Mendel using an interactive website. They differentiate dominant and recessive characteristics.

Students examine and research how cells make up our organs. They create a model of a tongue showing cells, tissues and the organ.

Learners model how the malaria-causing protist avoids immune response in its host. In this parasite biology instructional activity, students use printed cell images to model the way that Plasmodium changes surface protein markers every...

Students examine inheritance of blood types.  In the chromosome lesson, students create a model of chromosome and predict the blood type of offspring.

Students determine sources and extent of ground water contaminate, apply mathematics to model in real world simulation, and use technology to present results.

Young scholars examine the different parts of blood.  In this human blood lesson students work in groups and identify parts of blood and construct a model of human blood. 

Students use multicolored soft candies (gumdrops and candy orange slices) and toothpicks to create models of DNA structures. They discuss the fact that DNA must copy itself before splitting into two cells. Students demonstrate this by...

Students investigate and then build neurons in this lesson. They are examined as key parts of the brain and nervous system and seen as different from normal cells.

Tenth graders study how cells and organisms acquire and release energy through photosynthesis and cellular respiration. They explain that living organisms use matter and energy to synthesize a variety of organic molecules and they will...

Students explore viruses and bacteria. They construct three dimensional models of microorganisms recognizing size relationships by comparing the size of viruses with the sizes of bacterial cells.

Students use Excel to explore the geodynamics Model equation for ocean depth around a sea-floor spreading center. They complete an introductory tutorial on Excel for students with no prior Excel experience.

Students study HIV and model the course of an infection.  In this immune system lesson students examine HIV and AIDS and learn that it is a preventable disease. 

Students create a scale model of a motor neuron that is two hundred times larger than the actual neuron. They identify the structures of a neuron and observe neurons under the microscope then use a worksheet to convert actual sizes into...

Learners identify the different parts of the circulatory system and their function. They work together to create their own model of the system and use it to determine the rate of blood flow. They answer questions related to their model.

Students identify the 4-chambers and major blood vessels of the heart and construct a model of a 4-chamber heart. They sketch their model, identify the chambers/vessels, state the condition of the blood in each chamber/vessel, and...

Students explore genetics. They discuss how chromosomes and/or genes are regulated during the life of an organism. In a lab setting, students compare and contrast the genomic regulation of prokaryotic and eukaryotic cells using...

In this plasma membrane worksheet, students will explore how cells are able to maintain homeostasis and the function of the plasma membrane. This worksheet has 6 fill in the blank and 7 true or false questions.

Young scholars are introduced to the members and workings of a honey bee colony. They describe the structure of a comb, the day-to-day activities of honey bees, and name the four stages of bee development. They construct a honeycomb model.

Students study the stages of the cell division (meiosis) which results in the formation of gametes and study topics as crossing over, gene linkage, and human inheritance patterns in certain diseases.
