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...

Students compare and contrast plant and animal cells and then create a model of the latter. They visit Websites to view the cells and answer questions about them. In pairs, students create cell models using plastic baggies, syrup,...

Young scholars work in small groups to match cell vocabulary terms to the appropriate cell part in a photograph. They use a draw program to sketch a plant and animal cell.

Students examine the roles of an animal cell's parts, how each part relates to one another and then demonstrate their knowledge by writing a story about the animal cell structure.

Students explore cells. In this science lesson plan, students investigate how the cell is the basic unit of life, that cells divide slowly to become mass of cells, and that there is a gradual loss of cells throughout life.

In this cells worksheet, students define 14 words associated with cells. They answer 12 short answer questions about the structure and function of the cellular system.

Students read and complete a worksheet about the levels of organization of living things from cells to organ systems. They use a text book and the "Cells R Us" worksheet included to create a metaphor for each of the levels. They then...

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...

Fifth graders examine how a red blood cell travels throughout the body. Using a model, they follow the flow of blood throughout the entire body. They identify the functions of the lungs and discuss the difference of the blood entering...

The color School Bus Yellow was created in 1939 because science had proven peripheral vision detects yellow 1.24 times faster than other colors. Young scientists explore modern school bus transportation options and then discuss the...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

Put your heart into it. Scholars design and build replacements for mitral heart valves. Obviously, they can't test their creations on a real heart, so a box with marbles (to represent blood cells) will suffice.

The human body is an amazing thing! Explore the body with your high school class as they investigate each system in detail. They learn components of each organ system and disease processes that can negatively affect general health and...

Are the young leaders of tomorrow sitting in your classroom right now? Polish their skills to perfection using a series of teen leadership activities. Each lesson promotes both personal growth and team building, while helping scholars...

Learners practice relating rules of trigonometry and properties of circles. With a few simplifying assumptions such as a perfectly round earth, young mathematicians calculate the lengths of various paths between satellite and...

What is in that double helix? Explain intricate concepts with a variety of creative activities in a lesson that incorporates multiple steps to cover DNA structure, nucleic acids, and proteins. Pupils explore the history of DNA structure,...

It's electric! Young anatomists use Virtual Neurons software to build, control, and analyze complex nerve circuits within the body. Colorful and packed with content, class members enjoy interacting with the nervous system...

Thirty percent of the world's oxygen is produced by rainforests found throughout the world. Seventh grade learners explore the processes of photosynthesis and respiration through 10 days of labs, manipulatives, and discussions. They...

Students explore cell division through auditory, visual and tactile stations that each describe a stage of cell division. Then they apply the information from the stations in a mini-homework project that is tailored to one of the...

Students complete a variety of activities as they examine the ethics behind stem cell research and use.

Students idenitfy that cancer is a growth of mutated cells and that cancer cells are only one type of cell that causes disease in our body. They also identify that all eukaryotic cells contain a nucleus, cytoskeleton, and a cell...

High schoolers design and carry out an exercise to determine if a given fruit or vegetable is composed of cells. They dissect out sections of the fruit or vegetable, prepare stained slides, and make observations under a compound microscope.

Fourth graders, in groups, explore cells, the basic unit of all living things.
