Activities:
- Examine key mammalian traits such as warm-bloodedness, mammary glands, and skin coverings
- Investigate evolutionary adaptations like jawbone transformation and respiratory systems
- Compare heart structure and birth methods across different mammal groups
- Sort species on a phylogenetic tree and classify them as monotremes, marsupials, or placentals
- Analyze historical descriptions to identify mammals based on clues and context
- Practice scientific reasoning through elimination, deduction, and classification
Activities:
- Identify plant, animal, and bacterial viruses using hints (drag & drop)
- Explore the structure of the tobacco mosaic virus
- Find all the ways plant viruses can enter through wounds or openings
- Examine common symptoms of plant viral infections
- Hover over the HIV model to study animal virus structure
- Compare two main entry pathways: membrane fusion and endocytosis
- Observe how viruses replicate, assemble, and exit the host cell
- Match human viral symptoms with the correct virus and transmission method
- Study bacteriophages and how they inject DNA into bacteria
- See plaques (holes) on Petri dishes as signs of phage infection
- Answer the big question: how do viruses enter the cell? (Olympiad-style challenge)
- Learn about viroids (naked RNA) and prions (infectious proteins)
- Compare DNA vs RNA, and how viruses use genetic information
- Classify viruses in a table based on descriptions
- Contrast lytic vs lysogenic cycles and their role in gene transfer
