In this biology worksheet, students review and answer different questions based upon the molecules of DNA and RNA. They look at the specific protein order of the DNA strand and its synthesis.

In this biology worksheet students map out and describe the process of mitosis for the nine questions. The last four questions are several combined in each.

Engage in a class debate dealing with the allocation of organs to those waiting for a transplant. How do they decide who gets a transplant and who doesn't? Learners attempt to determine what is fair for the individual requiring an organ...

A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

After cutting down a forest to make a farm, how long would it take the environment to turn an abandoned farm back into a forest? Scholars study this exact scenario while they interpret many charts and graphs of the changing ecosystems as...

By counting differences in amino acids, biology stars examine the relationships between different primates. With information gleaned, they map out a phylogenic tree and discover common ancestry. You will need to create printable versions...

Pairs of high school biologists compare amino acid differences in the beta hemoglobin of different primates. They use the information collected to construct a phylogenic tree. Follow-up discussion questions are provided. This is a...

What happens when a non-native species is introduced onto an island? Santa Cruz Island, part of the Channel Island chain located off the coast of southern California, provides the perfect laboratory for young environmental scientists to...

Students investigate the physical structure of a protein by using a computer simulation tool. They record its primary amino acid structure while viewing it in three dimensions for a better visual recognition. There is also a comparison...

Students examine the experiment of Lloyd Godson who lived 13 days underwater. In this critical thinking instructional activity, students predict, study and discuss various aspects of the underwater voyage. The instructional activity...

Continuing their study of beneficial insects, young entomologists discover where in the world some of these bugs are. By labeling, coloring, and using the scale on a map, pupils explore the territories and arrival of the Asian lady...

Who doesn't love gold and silver? Brine shrimp, that's who! Learners conduct an experimental lesson to monitor the toxicity of gold and silver nanoparticles on brine shrimp. They synthesize solutions to expose the brine shrimp to and...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Students use background knowledge to summarize articles about skin cancer research and present them to the class and place their studies along a clinical study timeline. They are introduced to clincal trails and to various aspects of...

In this biology worksheet, young scholars use an interactive worksheet with 9 questions that ask them to review many parts of the concepts.

When the sun's rays can't reach the producers in a food web, where does all the energy come from? Extreme environments call for extreme food sources. Young scientists investigate creatures that appear to get their energy from methane...

How do we count the fish in the ocean? An engaging lesson models how to estimate fish populations with observational surveys. Class members begin by studying the behavior of fish on the coral reef in the oceans. They...

Students view video showing recent field work on a twenty two-year study of finch beaks on a small island in the Galapagos, showing natural selection clearly operating in the wild.

Life has its ups and downs ... especially if you're an animal! Biology scholars engage in a population study through an inquiry-based lesson. Pupils work together to explore the factors that affect deer populations, then examine the...

Students study animal classification and their interactions.  In this animals and engineering lesson students study animal communities and how engineers use this knowledge to create new technologies. 

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Display seven items for your biologists to consider. Are they living or non-living? How can you tell? This is a simple outline of what you can display and questions that can be discussed as this topic is explored. One way to use this...

Have you ever tried to find hidden items in a picture when you don't know what you are looking for or how many things are hidden? A lesson applies that same concept to sampling the deep sea habitats. Participants must first create a...

It is best to know all about the skeletons in the closet. The third segment in a five-part series focuses on bone structure, development and growth, and functions. Class members connect what they learn to their study of...
