Lesson
Variables and Fair Tests: The Plant Growth Investigation
Identify variables, control conditions, and design a fair pea-plant growth experiment.
Lesson
Case Closed: The Bean Seed Test
Use claim, evidence, and reasoning to build a science explanation from real bean seed sprouting data.
Lesson
Repeat the Test: The Fertilizer Procedure
Write and improve an experimental procedure so another scientist could repeat a bean-seedling fertilizer test the same way.
Lesson
Ready for the Lab
Prepare a lab bench, choose protective equipment, make safe decisions, and practice emergency response in an animated lab-safety simulation.
Lesson
Kelp Forest Collapse
Investigate an urchin barren, map the food web, and test trophic cascades in a kelp forest simulator.
Lesson
Photosynthesis Mission
Trace one carbon atom into plant matter through models, maps, and a photosynthesis builder.
Lesson
DNA: The Code That Copies Itself
Build nucleotides, use base-pairing rules, and model how DNA copies itself.
Lesson
The Cell's Assembly Line
Follow DNA instructions into RNA and proteins to see how cells build what they need.
Lesson
Looks vs. Letters: Mendel’s Pea Plant Mystery
Investigate why two purple-flowered parents can have a white-flowered offspring — through sorting, allele modeling, and a Punnett square build.
Nothing matches that combination yet.
