How Does Cell Size And Shape Affect Transport of Materials

This series of handouts and images asks young scientists to read short informational paragraphs, answer identification questions, and color and label diagrams of animal and plant cells. This is a complete resource that could be given as...

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

Engage young biologists in exploring the mysteries of life with this collection of hands-on activities. Enlisting the help of numerous digital resources, students get an up-close look at the structure of plant and animal cells as they...

What a packed lesson! Provide your class with the opportunity to learn about the cell cycle in several exciting ways. Biologists first learn about the theory behind mitosis, then proceed to view onion tips under the microscope and create...

Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

Students examine how living cells reproduce to make new cells.  In this cell reproduction lesson students complete a lab activity and answer questions. 

A robotic voice narrates as text and images appear to create a graphic organizer. First, the difference between prokaryotic and eukaryotic cells is described. The plasma membrane, cytoskeleton, nucleus, ribosomes, endoplasmic reticulum,...

What's the difference between body cells and sex cells? Learners explore the question and the process of meiosis using an interactive lesson. An animation describes the discovery of meiosis and describes its phases for a detailed and...

Understand that cell size is limited by volume to surface area ratio in this video. Learn that if cells become too big it cannot take in nutrients and get rid of waste fast enough. [8:55]

After studying the structure and functions of living cells using textbooks, internet or encyclopedias, students prepare a PowerPoint presentation on cell structure and present it to the class.
