Times have changed—and so have science practices. An introductory lesson describing the components of DNA begins with a discussion of the discovery of DNA and its perception in different cultures and genders. Scholars then learn about...

Two individuals share 99.9 percent of their genetic codes, yet diversity is observed everywhere. Young scientists learn about diversity through hands-on activities and an experiment. They apply the concepts of independent assortment and...

Explore how our chromosomes work to define human attributes. A complete unit presentation includes topics such as genetic disorders, blood typing, and Punnet squares. Learners answer questions throughout the presentation to apply the...

What happens when genes change? Junior genetic investigators examine the effects of mutation in the third unit of a four-part Biotechnology series. Individuals discover the types of mutations through a series of PowerPoints, then partner...

Start seeing double. The American Museum of Natural History website provides pupils with information about Dolly, the cloned sheep. Learners find out the procedure used to create Dolly along with why scientists clone animals.

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...

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...

Can scientists trace all humans back to a small region in Africa? An intriguing lesson turns back time to reveal artifacts leading scientists to believe human life originated in Africa and dispersed from there.

Gregor Mendel's work revolutionized agriculture from an art to a science. Explore Mendel's work with an interactive lesson that includes animations, video, and practice problems. The instruction describes the early discoveries that...

Let's get a closer look at DNA and other molecular structures. The first lesson in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource presents...

Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...

Different types of mutations cause unique types and degrees of muscular dystrophy. Scholars learn about the types of mutations and the impact on the body. They compare the location of the mutations and draw conclusions about how it is...

Match up the DNA code. Pupils read the website from the American Museum of Natural History about how DNA can determine whether a skin is from a particular type of reptile. Using the same technique, learners match up products with the...

Watson and Crick built the first model of DNA in the 1950s, and our understanding of DNA since then continues to grow exponentially. Scholars learn about protein synthesis by observing a presentation and completing a worksheet. Both walk...

Is obesity a disease or just a preventable risk factor for other diseases? Scholars attempt to form their own opinions by reading a background of the issue and watching videos that explore the main pro and con arguments using an included...

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...
