Students examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino acid...

Learners use and listen to analogies to help them become familiar with electrophoresis. One example is: Imagine a huge swimming pool full of water and many entangled nets (this is the agarose gel). A dump truck comes along and dumps...

High schoolers compare the anatomy of temperature and polar fishes. They explore the adverse effects of cold on metabolism and physiology and discuss how polar fishes adapt to their environments. Comparisons are also made to the DNA...

Have you ever wondered why you aren't taller or invisible? It all comes down to your dominant and recessive genes. Introduce your class members to genetics with a presentation that includes worksheets for young geneticists to...

In this introduction to biology, students complete a crossword puzzle with 22 questions. They identify common terminologies used in the study of biology.

In this biochemistry worksheet, learners complete a crossword puzzle with 36 questions. They identify different polymers and functional groups.

In this biology worksheet, learners answer 30 multiple choice trivia questions on various genetics and types of chromosome abnormalities.

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...

Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett...

COVID-19 = CO (corona) + VI (virus) + D (disease) =19 (the year the disease first appeared) NOVEL (unknown to scientists and never before infected human patients). A colorful nine-slide presentation details what is currently known about...

How does HIV operate at the molecular level? Pupils discover the progression from a healthy immune cell to one infected with HIV, watch an animation of the HIV life cycle, and finally identify each of the stages with illustrations...

Take young naturalists on an exploration of the world's tropical rainforests with this extensive collection of lessons and activities. Whether its creating leaf and flower prints or investigating the absorption spectrum of...

It's alive! Turn young biologists into mad scientists with this engaging genetics activity. Using their knowledge of chromosomes and genes, students create dragons with unique sets of traits,...

Engage young biologists in exploring the mysteries of life with this collection of hands-on activities. Enlisting the help of numerous digital resources, students get an up-close look at the structure of plant and animal...

Can peas have grandparents? Learn about inherited traits and heredity with a set of activities focused on Mendelian genetics. As your class learns about the process of passing traits along in Punnett squares, they take on the role of...

Viruses were nano before it was cool to be nano. The presentation covers the structure of a virus cell and the life cycle of a virus. It also includes two videos illustrating the virus cell in greater detail.

Think like an engineer and an agricultural scientist over the course of 12 lessons in a STEM based unit. Young scientists take on the roles of animal physiologists, animal geneticists, agricultural engineers, animal nutritionists,...

Our body manufactures antibodies that are the exact shape for the antigens it encounters. The simulation shows a 3-D model of an antibody and antigen pairing. It allows young scientists to explore the complementary shapes.

Molecules to the Max! refers to a movie released in 2009 about the world of atoms and molecules. A helpful discovery guide provides five posters on science topics typically covered at the middle school level. It also explains the...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Seems like a fairly simple question—until you begin asking your class! Get pupils acquainted with the characteristics of life through pairs classification, discussion, and scientific reading. The lesson plan, part of the K20 series, also...

What's your type? Genetically speaking, of course! Immerse your class in the world of karyotypes through an insightful activity from the K20 Center. Scholars take on the role of genetic counselors to determine the karyotype of offspring...

Who actually goes looking for a virus? Expose your class to the high-stakes life of an epidemiologist on the trail of the Nipah virus. Pupils engage in a short video, then examine how scientists predict, model, and find the source of...
