Lab objectives and outcomes

Students will be able to explain the concept of codominance by describing how two different alleles are expressed equally in the phenotype of heterozygous offspring.
Students will be able to apply Punnett squares to predict the genotype and phenotype ratios of offspring resulting from a codominant cross.
Students will be able to analyze the phenotypic outcomes of simulated breeding experiments to identify the characteristics of codominant inheritance.

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.
