SproutLab teaches grades 1–2 science with Predict-Observe-Explain (POE): your child commits a guess before seeing what happens, then finds out and hears why. Committing a prediction — even a wrong one — helps children learn far better than just watching. A wrong guess is celebrated as a discovery; there is no losing.
The three labs cover the grade 1–2 NGSS core: Light Lab (what we can see through, shadows — 1-PS4), Sound Lab (sound comes from vibration — 1-PS4), and Matter Lab (changes that can and can't go back — 2-PS1). Every prompt is spoken aloud with big buttons.
