Lab objectives and outcomes

Students will be able to identify the phenotypic expression of codominant alleles in the offspring after breeding organisms.
Students will be able to construct a Punnett square to predict the genotype and phenotype ratios of offspring in a codominant cross.
Students will be able to explain how both parent traits appear equally in offspring as a result of codominance.

Immune System Cells [Time Unguided]
A simulation where learners interact with key immune system cells—like macrophages, T cells, and B cells—to see how they recognize, respond to, and remember pathogens, building understanding of immune defense mechanisms.

Powered by SimGenie AI

SimGenie acts as a built-in lab assistant. A learner who gets stuck can ask for a hint by voice, and it adapts its guidance to what they are doing in the scene.

Genetic Engineering [Timed]

A simulation where learners explore the process of genetic engineering by selecting genes to modify traits in organisms, visualizing techniques like gene splicing and recombinant DNA, and understanding real-world applications and ethical considerations.

BiologyGrades 9-12

Osmosis [Timed]

A simulation where learners observe water movement across semi-permeable membranes in plant and animal cells, adjusting solute concentrations to explore hypotonic, hypertonic, and isotonic environments and understand the principles of osmosis.
