Changes in the Environment

Students learn that different species can arise from a common ancestor if different groups have different selection pressures.

Use a model to study the effect of a consumer (rabbits) on two species of producers (grass and weeds).

Conflicting Selection Pressures

Observe how heredity and natural selection allow a population to adapt to a changing environment.

Explore what DNA is and how proteins are synthesized from the genetic information stored in it.

Experiment with Ecosystems

Experiment with virtual ecosystems and test your hypotheses about producer/consumer and predator/prey relationships.

Explore how changing the DNA sequence can change the amino acid sequence of a protein.

Mystery Plants Mystery

Learn about intraspecific differences and how variation in a population can help a species adapt to living in different environments.

What do plants eat? This unit explores plants and how they make food.

Population Explosion

Study how populations stay in balance with their environment and respond to various factors such as food supply and predators

Predators and Prey

Students learn that selection pressure can lead to a change in the characteristics of a population.

Protein Folding

Explore how hydrophobic and hydrophilic interactions cause proteins to fold into specific shapes.

The Virtual Field

Learn the life cycle of organisms, variation within a species, and heritability of traits.
