Mouse Genetics (One Trait)
Breed "pure" mice with known genotypes that exhibit specific fur colors, and learn how traits are passed on via dominant and recessive genes. Mice can be stored in cages for future...
Mouse Genetics (Two Traits)
Breed "pure" mice with known genotypes that exhibit specific fur and eye colors, and learn how traits are passed on via dominant and recessive genes. Mice can be stored in cages for future...
Breed "pure" chickens with known genotypes that exhibit specific feather colors, and learn how traits are passed on via codominant genes. Chickens can be stored in cages for future...
Fast Plants® 1 - Growth and Genetics
FREE with no time limit!
Grow Wisconsin Fast Plants® in a simulated lab environment. Explore the life cycles of these plants and how their growth is influenced by light, water, and crowding. Practice pollinating...
Fast Plants® 2 - Mystery Parent
In this follow-up to Fast Plants® 1 - Growth and Genetics, continue to explore inheritance of traits in Wisconsin Fast Plants. Infer the genotype of a "mystery P2 parent" of a set of Fast...
Construct a DNA molecule, examine its double-helix structure, and then go through the DNA replication process. Learn how each component fits into a DNA molecule, and see how a unique,...
RNA and Protein Synthesis
Go through the process of synthesizing proteins through RNA transcription and translation. Learn about the many steps involved in protein synthesis including: unzipping of DNA, formation of...
As a pediatrician, students learn about genes and protein synthesis to try to help a baby girl named Lucy who has an immunodeficiency disease.
Scan the DNA of frogs to produce DNA sequences. Use the DNA sequences to identify possible identical twins and to determine which sections of DNA code for skin color, eye color, and the...
Sort and pair the images of human chromosomes obtained in a scan. Find differences in the scans of the various patients to find out specific things that can cause disease, as well as...
Set the initial percentages of three types of parrots in a population and track changes in genotype and allele frequency through several generations. Analyze population data to develop an...
Observe the effect of predators on a population of parrots with three possible genotypes. The initial percentages and fitness levels of each genotype can be set. Determine how initial...
Use genetic engineering techniques to create corn plants resistant to insect pests or tolerant of herbicides. Identify useful genes from bacteria, insert the desired gene into a corn plant,...
GMOs and the Environment
In this follow-up to the Genetic Engineering Gizmo, explore how farmers can maximize yield while limiting ecosystem damage using genetically modified corn. Choose the corn type to plant and...
Explore how sex cells are produced by the process of meiosis. Compare meiosis in male and female germ cells, and use crossovers to increase the number of possible gamete genotypes. Using...
As a geneticist in an animal hospital, students learn about genetic changes in meiosis to determine the reason why a male cat can have calico fur coloring.
Working as a CDC researcher, students investigate an outbreak of multi-drug resistant bacterial infections and determine how evolution was involved by tracing the source and cause of the...
Learn how DNA is compared to identify individuals. Identify the sections of DNA that tend to differ and use PCR to amplify these segments. Then use gel electrophoresis to create DNA...
How Free Gizmos Work
Start teaching with
20-40 Free Gizmos. See the full list.
Access lesson materials for Free Gizmos including teacher guides, lesson plans, and more.
All other Gizmos are limited to a 5 Minute Preview and can only be used for 5 minutes a day.
Free Gizmos change each semester. The new collection will be available Jan 01, 2024.
About STEM Cases
Students assume the role of a scientist trying to solve a real world problem. They use scientific practices to collect and analyze data, and form and test a hypothesis as they solve the problems.
Each STEM Case uses realtime reporting to show live student results.Introduction to the Heatmap
STEM Cases take between 30-90 minutes for students to complete, depending on the case.
Student progress is automatically saved so that STEM Cases can be completed over multiple sessions.
Multiple grade-appropriate versions, or levels, exist for each STEM Case.
Each STEM Case level has an associated Handbook. These are interactive guides that focus on the science concepts underlying the case.
