Students identify each phase of mitosis and the main characteristics of each. Students prepare a microscope slide with onion root tip. Students observe the cell division occurring in the cells and label the mitosis phases observed.

In this microviewer worksheet, students observe several types of cells. Students draw each type of cell and label the important parts. Students also answer questions relatable to the cell and the purpose for study.

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Here is a lab activity adequate for use with any full lesson on environmental factors that shape animal adaptations or marine animal characteristics. Pupils will discuss the role plankton plays in the environment and filter-feeding...

Students investigate osmosis using egg cells with the shells removed. In this osmosis lesson plan, students remove the shell of an egg by letting it soak in vinegar for two days. They take measurements and observe the cell. They soak the...

Students explore the surface area to volume ratio in cellular respiration. While participating in an interactive lab experiment, they examine proportional surface area and discuss nanotechnology. Students observe the effectiveness of...

Students observe the general structure and organelles of plant and animal cells. Students prepare microscope slides of elodea, onion, check, and cork and identify the cells by size and shape as unicellular, multicellular, plant or animal.

Sixth graders study living cells and their functioning units.  In this cell lesson students color cell diagrams, answer questions and discuss the differences between plant and animal cells. 

Students measure the rate of diffusion and to calculate the surface area to volume ratios of varying cell sizes. The lesson is very clearly organized with a useful student worksheet provided. They perform a lab experiment which is...

Electrons flow from negative to positive, but the general consensus is that current flows from positive to negative. Scholars explore current through construction of circuits in both series and parallel. The focus is on voltage,...

Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...

Information on the biomedical use of nanotechnology, specifically in the detection and treatment of cancer, is the focus of a lesson that seems like it is out of a science fiction novel. Pupils learn about electrophoresis, which is used...

It's a small (nanotechnology) world after all! The first segment of a six-part series gives an overview of nanotechnology, its principles and applications, and shares some of the engineering applications of nanotechnology. A...

Students study the livers parts and functions then follow a lab experiment to watch first hand how the gut uses bile to physically break down fatty substances into smaller pieces.

Students pretend they are each genetic engineers with a test tube of unknown DNA (PCR'd) possibly taken from blood cells of someone with a genetic condition.

Ninth graders research the different field of bioengineering. In this biology lesson, 9th graders differentiate meiosis and mitosis. They discuss the pros and cons of using radiation in medical diagnostics.

Students explore the relationship between pressure and vessel diameter. They are given an open-ended design challenge in which they engineer their own remote repair device. Students see a model that represents how elevated blood...

Learners identify the different types of batteries available in the market. In this science lesson, students discuss how to select the right batteries for a car.

Students explore human senses. In this applied Science lesson, students utilize their senses to distinguish various objects. Students explain their descriptions.

Students read about Humane Genome Project, examine structure and function of DNA, and participate in gel-electrophoresis lab. They complete Internet activity to test their knowledge of DNA.

Pupils are introduced to biotechnology by using models. The teacher uses A Sourcebook of Biotechnology Activities, Rasmussen and Matheson project co directors. One of the activities in the book is: students use a scale models to very...

Students examine and discuss the concepts of diffusion and osmosis. They observe the effects of diffusion on eggs by recording the change in an egg's size and the amount of liquid substance that remains.

Students review the structure and function of DNA, genes, and chromosomes and are engaged by a demonstration illustrating the relative size of DNA, genes and chromosomes. They also describe through analogy and model the structure and...

Students make predictions about the number and colors of M&M's in a snack size package. They create an Excel spreadsheet to record the data from their small group's bag, create a graph of the data, and discuss the variations of data...
