Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

Much like the tale of Humpty Dumpty, proteins, once altered, will never be the same again. Honors and pre-AP biology classes explore the delicate world of enzymes via a Webquest and lab experiment. The teacher's guide contains all...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Did you know that your DNA can be damaged tens of thousands of times per day? Learn about the ways that damage to just one strand of your DNA can be fixed, or in extreme examples, result in genetic mutation such as cancer. 

After an explanatory introduction to sugars and enzyme activity, biochemists discover whether lactase is needed to digest lactose, sucrose, and milk as a whole. High school science lab skills are required for these investigations.

Here is a five-star slide show that elaborates the topic of enzyme activity. With graphics that purposefully enhance the material, viewers learn about enzyme structure, function, and different roles that they play in a system. If you are...

Biology learners describe the metabolic pathways and the transcription and translation of genetic information. They will party on the last page as they trace the flow of information through a large and colorful diagram.

Teach your biology class about enzymes with this well-organized and impressive presentation. "Learning Check" and "Solution" slides are inserted throughout so that you can stop and have learners review. Why reinvent the wheel? Save...

Why do people age? Scholars explore the concept of telomeres and why they are so important in cells. They learn about the role of telomerase and why it is active in some cells—but not in others. The video also explains why some organisms...

Are there cyborgs amongst us? Once only found in science fiction, the proliferation of implants has surrounded us with people augmented with insulin pumps, artificial joints, and prosthetic limbs. There is a catch, however. An engaging...

Have you ever wondered why some people are lactose intolerant? Participants test simulated patients in a hands-on lab activity to find out! They learn about lactose intolerance by performing an experiment, analyzing data, and drawing...

What does a cell do when DNA is not copied correctly? An informative video shows budding scientists an example of a mismatch mutation during DNA replication. Viewers learn that to prevent a mutation from occurring, cells have mechanisms...

Personalized medicine prevents many trial-and-error scenarios when time counts the most. Learn how gene expression and screening genomes improves health outcomes in cancer patients, those with auto-immune disorders, and more. An online...

Does natural light damage or repair DNA? Learn the answer discover the scientists who researched the topic with an online interactive. Scholars read through an online animation presenting the content at their own pace. Then, they read...

Can organic molecules come from a pre-biotic environment? Stanley Lloyd Miller proved it is possible when exactly the right conditions exist. Learn about his experiment and the other experiments later building off of it that changed the...

Don't leave anything to the imagination! Use an animation to demonstrate the replication of DNA. The animation shows how the double helix separates and then begins copying nucleotides to create a copy.

Very few universities still offer a master's degree in the ecology of grasses, but that was the degree that led George Wells Beadle to an interest in genetics and later a Nobel Prize. Scholars learn about the discoveries of Dr. Beadle...

Around the world, about 2/3 of adult humans are lactose intolerant. Scholars work in small groups to discuss a few statements about lactose intolerance. Then, they watch a video on the topic and readdress each statement. Whole-class...

Many physicals include a blood glucose test, but what are doctors actually testing? Scholars graph and interpret blood glucose data, allowing them to observe the differences in lactase persistence and draw conclusions. They then connect...

Enzymes proofread DNA, reducing the error rate to one in one billion base pairs. Learn about the important process and so much more with the help of a presentation. It opens with the history of DNA and the major scientific contributions...

You matter—unless you multiply yourself by the speed of light squared, then you energy! Scholars learn about matter, energy, the elements and so much more using an informative presentation. Completing the included worksheet creates a...

No matter where you stand on the controversial topic of genetic engineering, the science that makes it possible is extraordinary. An animated video describes a process of genetic engineering involving bacteria. The quick demonstration...
