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...

Is DNA still present after picking fruit or cooking vegetables? Biology scholars extract and collect DNA strands in an impactful lab. Working groups prepare their samples and compare their results to negative and positive standard...

Feeling confined by your current cell-teaching strategies? Try an interactive inquiry-based plan! Young cellular biologists explore the different types of cells, plus their structures and functions in a hands-on computer modeling...

Lights, camera, action! With the cell at center stage, guide your seventh grade biologists through the tiny drama that plays out within every living thing. Then, enjoy the show as they portray the organelles they've studied—a performance...

Despite their microscopic size, eukaryotic cells are probably one of the most complex systems ever! Explore the structure and function of the major organelles of eukaryotic cells — the nucleus, ER, ribosomes, golgi complex, lysosomes,...

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...

Now, this is a clever approach to understanding cell organelles; seven pairs of organelles are listed, and pupils write an explanation of how each pair cooperates to perform certain cell functions. Organelles include the nucleus,...

New ReviewInvite 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....

AP® free-response questions are often challenging for scholars. Give them practice writing free-response questions using former questions from the AP® Biology exam on topics such as genetic mutations, cellular respiration, evolution, 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...

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...
