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...

It is hard to believe a 300-foot-tall Redwood tree began as a single cell hundreds of years ago. How did it grow so large? Observe how different kinds of cells (bacteria, sex cells, and eukaryotic cells) reproduce or make more cells for...

Adult humans are made of around 40 trillion cells that can't be seen these without some really powerful microscopes! Learners tour both prokaryotic and eukaryotic cells, learning how their structures are similar and different, and then...

Here's a great activity to bring excitement to protein-studded cell membranes. Pass out the instructions and templates to individuals or small groups. They cut and fold their phospholipid bilayer, channel protein, receptor protein,...

The differences between prokaryotic and eukaryotic cells are explained and the parts of each are highlighted. Discover the major organelles found in an animal cell and each of their functions. Paul Andersen does an excellent job once...

Invite biologists to watch an animal cell feasting on a bacterium as just one exciting part of a multi-faceted and extendable activity. Topics addressed include cell organelles and the differences between eukaryotes and prokaryotes....

Do young scientists know that some traits are only passed down by the mother? Mitochondrial DNA is an interesting phenomenon that provides researchers with a lot of useful information. Scholars learn about the endosymbiotic theory, what...

A remarkably high number of scholars passed the AP Biology exam in 2016 with over 61 percent earning college credit. The College Board released the entire free-response section for future scholars to study. After answering the eight...

Gene switches work similarly to light switches in controlling one feature of their environments. Scholars study the Pitx1 gene in a specific type of fish. They learn the different ways this switch controls various body parts and...

The 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...

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...

Much like your favorite superhero, the axolotl has amazing super powers! Explore the extraordinary world of the salamander that never grows up in a video from a larger science playlist. Content includes axolotl behavior versus normal...

How does cancer begin, and why can it get so out of control? Curious young cytologists use an interactive resource to study the cell cycle. After reviewing the background information, individuals go step-by-step through the process of...

How do some viruses spread so quickly, and why do they make us feel terrible? Answer these (and many more) questions through a simple yet impactful lessons. Pupils observe demonstrations that show the two methods viruses use to escape...

Eukaryotes include humans, animals, and plants. Scholars learn about the parts of eukaryotic cells. They design models of a store and match the correct function of each part to the function of a part of the cell. They review their...

Without the cell membrane, our cells just couldn't keep it together! What else does this multifunctional membrane do? Take a deeper look at the fluid mosaic model using a video from an expansive biology playlist. Topics include embedded...

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...

Ready to begin cell biology in a grand fashion? Start the adventure using a short but thorough video from a vast biology playlist! From prokaryote to eukaryotes, Golgi to chloroplast, the narrator guides viewers through the cell membrane...

Cells are busy places! How do things move around in such a tiny environment? Introduce young life scientists to the types of cellular transport through a video that is part of a large biology playlist. Animated characters demonstrate how...
