The Genetics of Resistance to HIV Infection

Explore the relationships between viruses, cells and the immune system, and the role of genes in disease resistance. See how mutations in an HIV receptor confer relative resistance to infection.

Genetics: Complex Inheritance Patterns

Our blood types are transmitted through multiple allelic inheritance. Identify the antigens and antibodies of the four different blood types: A, B, AB and O.

Genetics: Sex Linkage

Some traits, such as colorblindness, are related to gender. Complete a Punnett square showing the possible genotypes of children born to a colorblind mother and a father with normal vision.

Geologic Timeline

Test your knowledge of major events (formation of the solar system, first appearance of water, etc.) in geologic history. Afterwards put the events in the correct order on the timeline.

Gray Whales

Track gray whale migration. Use live data to observe migration patterns.

Groups: Ionic Bonding

Use your knowledge of families of elements. Create compounds by combining individual ions.

Hazardous Waste in the Home

Many sources of hazardous waste can be found in your own home and require special disposal. Can you determine which household items are hazardous, which can be recycled, which go out with regular household trash and which should be washed down the drain?

Human Genome: Transcribe this DNA

Review the different combinations of nucleotides that form pairs. Then move nucleotides into their correct places on the RNA strand to transcribe the DNA.

Human Genome: Transcription

Observe the process of transcription at the level of the nucleus. See how the information in a segment of DNA (gene) is copied into another type of genetic material called messenger RNA.

Hummingbirds

Observe hummingbirds and report their sightings online. Share and review the sightings with other students/classrooms to track hemispheric migratory patterns.

Identify Rock Types

Identify the three major kinds of rocks. Learn some of the key characteristics that help you tell them apart.

Isotopes, a Weighty Matter: Isotope Quiz

You will be presented with three different isotopes of the same element. See if you can calculate the atom's average relative mass.

It's Elementary: Building Elements

Use your knowledge of scientific notation systems used to describe orbital configuration. Build up orbitals and electrons piece by piece in order to construct a given element.

Laser Cooling

Slow a sample of fast-moving atoms with a laser to capture them in a trap by setting the temperature of the oven and adjusting the strength of the magnets. Once trapped they can be cooled and used in a variety of experiments.

Made from Dots

Notice how magazines print photos using dots made up of percentages of only three colors and black. Try your hand at using percentages of cyan, magenta and yellow to match the magazine color displayed.

Melting Rocks

Turning solid rock into liquid magma involves changing its temperature, pressure and water content. Try your hand at melting rock to create magma.

MiniMouseLab

Use a simulation to operate an elevator and see its motion. Examine the graphs that describe the motion you produce.

Monarch Butterflies

Observe monarch butterflies and report their sightings online. Share and review the sightings with other students/classrooms to track hemispheric migratory patterns.

Name That Atom

View twelve atoms each composed of different numbers of protons, neutrons and electrons. Determine whether the atom is an anion, cation or isotope and identify the element on the Periodic Table.

Periodic Table Assessment: Test Your Skills

Test your knowledge of atoms, orbitals, periods/groups, characteristics of families, isotopes and relative mass. Take this 39-question test, review your correct and incorrect answers, and print out your assessment.
