A Pumpkin, from Flower to Next Seed
Follow a pumpkin from two different flowers to the carved fruit and seeds for a later generation. Apply qualified Extension and USDA clues without relying on an unseen plant image.
Science & Nature
After the Flower: How Seeds Travel
Follow seeds through wings, digestion, forceful release and humidity-controlled cones. Separate release, travel, dormancy and population-level survival across eight discoveries.
Science & Nature
Backyard Evidence Lab
Read small invented observation tables, sort what they support from what needs an experiment, order field-note steps, and match clues to their evidence type.
Science & Nature
Bats Beyond the Vampire Myth
Meet a ground-listening hunter, a cactus pollinator and food-sharing vampire bats. Eight discoveries replace a single spooky stereotype with different animals and ways of life.
Science & Nature
Build a Food Web
Wire up who eats whom in three simplified habitat models, then follow the rules to trace what changes when one species is removed.
Science & Nature
Cause Chain Courtroom
Judge short cause-and-effect chains: match each link to its mechanism or evidence, then find the link where the argument is weakest.
Science & Nature
Citizen Science Team Builder
Work together on an invented backyard bird-count team: assign roles from stated needs, sequence a weekly session, and decide which records to trust.
Science & Nature
Cold Surface Detective
Use formation records and surface measurements to distinguish hoar frost, frozen dew and rime across eight evidence puzzles.
Science & Nature
Eight Lights in the Dark
Blue surf, rainbow combs, luminous wood and a predator’s private searchlight: discover eight reasons the natural world can look otherworldly. Some creatures make light; others transform light arriving from outside.
Science & Nature
Fair Test Designer
Design simple plant, ramp and dissolving experiments by choosing what to change, keep the same and measure, then spot flaws in other people's tests.
Science & Nature
Field Notebook Style
Choose, match, slide and rank your way through eight nature-notebook scenes, then see two preference scales: Details to Patterns and Sketching to Counting. There is no correct answer.
Science & Nature
Follow the Drop
Trace raindrops through an invented mountain-to-sea watershed by ordering route steps, doing flow arithmetic, and matching coastal places to water-cycle processes.
Science & Nature
Freeze-Thaw Pothole Predictor
Work through a simplified road-damage model: match each stage to its cause, order the steps, and predict what damage comes next.
Science & Nature
Mineral Scratch Lab
Learn what hardness means for minerals and how the Mohs scale orders them, then read invented scratch logs to rank samples by the lab's own toy rules.
Science & Nature
Moon Mission Control
Play flight controller across eight calls: sequence launch steps, solve transit problems, and match return constraints to reasons, then check your accuracy and read the explanations.
Science & Nature
Mystery Material
Solve eight reasoning puzzles that match what an object needs to the material property that explains it, then choose materials from a supplied property table.
Science & Nature
NASA’s Spooky October Sky, Explained
Read eight original text descriptions of NASA and Chandra images, then discover what the eerie shapes actually record: active regions, reflected starlight, gas emissions, a young star’s shadow, and more. Every observation is historical or archival; nothing here promises what is visible tonight.
Science & Nature
Night Sky Clue Hunt
Tap clues on schematic sky diagrams to find what moves, what is lit and where things sit, then choose the explanation that fits the dated records.
Science & Nature
Pickles to Pond Osmosis
Predict which way water moves into or out of cells in salty brine, sugar syrup and fresh pond water, then match everyday examples to the process.
Science & Nature
Predict, Reveal, Revise
Make three provisional predictions, then read new labeled results and choose which explanation the completed evidence still supports.
Science & Nature
Rock Cycle Road Trip
Follow one imaginary rock through heat, weather and pressure. Pick the change each stated condition supports, choose a route, then trace the resulting material.
Science & Nature
Scale Shock
Sort invented specimen cards by size after converting mixed units, then answer four scale-bar and size-comparison questions.
Science & Nature
Season Reasoning Gauntlet
Reason through eight puzzles set on an invented planet to test whether orbit distance or axis tilt, day length and sun angle better explain seasons.
Science & Nature
Species Under Pressure
Make four management choices for an invented drying wetland, then test your reasoning on cause chains, water-cycle terms and survey data.
Science & Nature
Spot the Weak Science Claim
Read short invented headlines, pick the claim that outruns its evidence, match weak spots to the evidence that would help, then order the steps of a fair test.
Science & Nature
The Pollinator Shift
Guide an invented garden through spring, summer and autumn. Solve bloom-timing puzzles for an accuracy score, then see two separate preference scales: Quick Tweaker to Slow Observer and Focused Planter to Mixed Planter. Taste choices have no correct answer.
Science & Nature
The Sound You Cannot See
Across eight tasks, listen to original tone clips and solve text puzzles to work out what a sound traveled through, which path change altered it, and how far an echo went.
Science & Nature
Tiny Terrarium Logic
Assign roles to the parts of a paper-model sealed jar, then follow stated rules through three-step changes to see which effects the model supports and which it leaves open.
Science & Nature
Weather Without the Forecast
Read invented pressure logs, cloud sequences and wind shifts, then pick the change that best fits, order clue-to-outcome chains, and choose what to watch next.
