Featured Biology Activities
Cellular Respiration
Explore how your body converts the chemical energy of glucose into the chemical energy of ATP.
Changes in the Environment
Students learn that different species can arise from a common ancestor if different groups have different selection pressures.
Competition
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 by making favorable mutations more common and unfavorable mutations less common.
Diffusion
Investigate how the random motion and collisions of particles results in diffusion.
Diffusion, Osmosis and Active Transport
Explore how water and ions can diffuse both passively and actively through cell membranes.
DNA to Protein
Explore what DNA is and how proteins are synthesized from the genetic information stored in it.
Experiment with Ecosystems
This open-ended series of models allows students to experiment with virtual ecosystems and test their hypotheses about producer/consumer and predator/prey relationships.
Leaf Photosynthesis
This NetLogo model of leaf photosynthesis shows the macroscopic outcome of the reaction.
Meiosis
Learn how meiosis and fertilization shuffle the alleles that offspring inherit.
Meiosis Lab
Explore meiosis and fertilization in dragons in a special lab that gives students the power to recombine alleles.
Modern Genetics
Students breed dragons to learn concepts in modern genetics.
Molecular Self-Assembly
Explore how molecules assemble themselves into defined patterns, a process called molecular self-assembly, using a unique set of computational models.
Mystery Plant Adaptation
Students learn that species are adapted to their environments and that variation in a species can help the species adapt to changes in the environment.
Mystery Plants Mystery
Learn about intraspecific differences and how variation in a population can help a species adapt to living in different environments.
Natural Selection
Students explore how changes in the environment affect both plants and animals in a simple ecosystem.
Plants
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 Partnering and Function
Build "partnerships" between a protein and small molecules, explore the effects of surface charge, polarity and shape on partnering, and learn the importance of a "good fit" between molecules.
The Geniverse Lab Demo
Students investigate dragon phenotypes and genotypes, run breeding experiments and solve genetic problems in a virtual lab.
The Virtual Ecosystem
Students learn that organisms with similar needs compete with one another for resources.
The Virtual Field
Learn the life cycle of organisms, variation within a species, and heritability of traits.
The Virtual Greenhouse
Students learn about basic needs of organisms. An organism thrives in specific environments that match its specific needs.
Variations and Adaptations
Students determine how climate can affect ecosystems.
