At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Can you eyes be fooled into seeing colors that aren't actually there? Budding scientists view a presentation that addresses this topic. They explore how their eyes interpret color through the retinas and messages sent to the brain. They...

Middle schoolers explore how to read the resistor color code and a meter.

Students commonly ask question about vision and color perception which may be difficult to answer without taking. They use this module that contains a list of questions which often arise when biology students are studying the nervous...

Sex-linked traits indicate a gene's location on a specific chromosome. Scholars learn about sex-linked traits and the specifics behind color blindness in the videos. Then they complete the online interactive to apply their knowledge...

Six different chromosome activites introduce biology aces to heredity, chromosomal abnormalities, sex-linked traits, and the human genome. The hands-on activites are fairly simple for the teacher to prepare and will prove to be both...

Young scholars use the scientific method to explore how to make different colors with paint. They problem solve ways to darken and lighten colors without using black and white paint. Students hypothesize how to create new colors, and...

Our bodies have some amazing capabilities, but there are some limitations. Explore the limitations of the human eye through the eighth lab activity in a series of 12 biology lessons. Individuals measure their own peripheral vision...

Young scholars recognize that the colors they see are a result of the reflection of light. In this light and color lesson, students predict what color will be produced when lights are mixed. They identify the three primary colors and...

In this biology worksheet, 9th graders create a Punnett square to show the possible offspring of a carrier female and a normal male for color blindness. Then they draw a pedigree for the family and indicate whether the daughter is...

Using deductive skills and reasoning based on the data provided about a family's blood genotype, blood phenotype, chromosomes, and genetic conditions, 9th graders answer the questions below. The conditions discussed are Down Syndrome and...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Do you know the name for the biological study of interactions? A short presentation with accompanying worksheet introduces individuals to ecology. The materials offer a broad overview of the subject and the levels of organization to...

Ninth graders review the terms "aneuploidy," "fetus," and "karyotype" in this vocabulary learning exercise, which includes three multiple choice questions about each term. This activity could be expanded into a more developed vocabulary...

Students investigate the poisonous frogs of Manu, Peru. They watch and discuss a video, conduct Internet research on poison frogs, accurately color downloaded template models of the frogs of Manu, and create a poster using the colored...

Eleventh graders explain why colour blindness is more common in men than women.

In this light and the eye activity, students perform eight tests to show the blind spot in the human eye, to demonstrate Benham's disk, to show how polarized lenses work, to show how light scatters, to demonstrate fiber...

Get a little batty with life science! This fun simulation game replicates how bats use echolocation to hunt moths in their native Hawaiian habitat. After creating blind folds and discussing some basic principles of echolocation, learners...

Students examine various inheritance patterns using pedigrees. In groups, they predict what might happen to the offspring of a woman with normal vision and carries the recessive allele gene. They determine the genotypes of the man and...

Though they be but little, they are fierce! Young biologists read about eight different species of ants, and discover how the anatomy of their heads can explain the way they live and what they eat.

From the iris and retina to glasses and contact lenses, learners will be excited to see what activities are in store for them as they learn about the complex organ of the human eye.

Personality traits and physical appearance traits within families are the focus here. Learners make a poster which lists the shared physical traits they have with their family. Peers look at each poster and write down the traits they see...

Why are so many inherited diseases more prevalent in populations of specified races? Scholars learn about pedigrees and genetics using a reading, an animation, primary sourced letters, a short video, a biography, a guided practice...

Students work with a partner to complete an inventory of their traits and compare and discuss their unique qualities. In this biology lesson, students determine percentages for the frequency of observed traits of classmates, compile the...
