New ReviewThe human body contains more than 200 types of cells, and plants contain many other unique types of cells. While a huge variety of cells exist, they appear to have very similar structures. A detailed presentation describes the structure...

Can science scholars describe a nucleus without mentioning DNA, or a chloroplast without mentioning the color green? Test their organelle understanding through an exciting card game. Groups take turns guessing the correct organelle or...

Cells are both made of molecules and make molecules all at the same time! An exploratory lesson provides a means for scholars to research the components of cells made of molecules and also investigate the molecule-producing power of...

Cells of different organs have unique cell functions. Learn how cell functions vary depending on their roles in the body using an inquiry-based activity. Scholars analyze the cell structure to make comparisons to its functions, allowing...

The function of a cell determines the shape and structure of the cell. An inquiry-based activity explores the different functions and shapes of cells. They make connections between these two characteristics and develop conclusions about...

Is our skin color determined only by genetics? Explore skin science through a video and related interactive. Young biologists discover the cells of the epidermis, how melanin is made, and the factors that influence the outward appearance...

Eukaryotes—were we born from an act of predation that backfired? Ponder this and other questions of evolution with a video from a well-written biology playlist. Topics include the origins of mitochondria and chloroplasts, unusual...

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...

The third in a series of 10 STEM project-based lessons focuses on cells types, functions, and physiology. Through research, discussions, writings, and presentations, groups learn about the difference between plant and animal cells, the...

A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

Teach your class how to get out of a cell — or break in. The third installment in a seven-part series introduces the class to cell membranes and their functions. The lesson plan includes information to present to the class,...

Why can't plants escape prison? Because their cells were surrounded by walls. Introduce viewers to the evolution of plants with a video that discusses the differences between prokaryotic and eukaryotic cells, plant cells' organelles, and...

The narrator of this video relates animal cells and their organelles to a city. He then explains what the organelles do for cells, where they are located, and why they are important. 

If life on Earth began as a prokaryote, how did eukaryotic cells arise? Learners explore the history of endosymbiosis from Dr. Lynn Margulis' first writings, which were not widely received to the evidence of mitochondrial DNA. They then...
