When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Seeing is believing! Bring DNA to life for young biologists using a simple extraction lab. Individuals extract the DNA from wheat germ, then place it in a microcentrifuge tube for observation. They thread yarn or other material through...

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...

Energize biologists with colorful images in an activity that captivates the imagination while demystifying the subject of cellular respiration. Participants build comprehension skills and access core content knowledge by analyzing text...

HIV mutates rapidly, making treatments challenging to find. Scholars learn about why it mutates so quickly and how scientists race to find treatments. The resource approaches the issue from both a molecular and evolutionary perspective...

Biology buffs illustrate the workings of the cell membrane when they complete this checklist. Not only do they draw the structure, they also draw gradients and mechanisms for the transport of materials across the membrane. Your advanced...

DNA is the code for all biological traits, both plant and animal. Using an exploratory lesson, learners begin to explore the concept of a biological code by decoding word puzzles. They then extract DNA from plant cells using detergent to...

Help! Someone's trying to take my DNA! An interesting lab experiment has scholars use basic materials to extract DNA. By applying ethanol, cold water, and a protease enzyme, like pineapple juice, they pull strands of DNA from peas,...

Sugar isn't good for you, but it's great for microbes. A simple experiment has pupils investigate the digestion of starch by microbes to produce sugars. They apply two bacterial cultures, an amylase solution, and distilled water on a...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

Should athletes carb load before an event or consume carbohydrates during the competition? Scholars discuss how to set up a hypothesis and experiment to answer a question relating carbohydrates and athletic performance. Then, they read...

We have all heard that we are what you eat, but what are we eating? An informative lesson opens with a discussion of the foods pupils have recently eaten. Then, young scientists perform four experiments on seven...

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.

How effective are cells at repairing UV damage? An inquiry-based lesson has learners experiment with organism by exposing them to various levels of UV light and then examining their DNA after a period of time. Pupils test different...

Read about the structure of RNA, its components, and how they fit together. This source includes visual aids to help you and a list of the different kinds of RNA and their functions.

A very good page that uses a Q&A format to describe the process of gel electrophoresis. Interactive in a rudimentary way.

Understandable lessons about numerous aspects about the composition, function, and interactions of proteins. Each starts with an interactive quiz and links to a tutorial.

In this unit you can read about the molecules that compose us and understand their biological functions. It includes 18 interactive activities.
