Grades 9-12 · Careers and Finance · LabPrototype Lab
Design, prototype and test a product; iterate based on test results.
Grade 1 · Math · LabPaperclip Ruler
Measure classroom objects with paperclips, cubes or shoes; compare results and discover why same-size units matter.
Grade 3 · Math · LabKitchen Lab
Measure liquids and weigh ingredients for recipes while a timer runs; plan elapsed time so dinner is ready at 6.
Grade 6 · Math · LabSmoothie Lab
Mix fruit in ratios and taste-test (the tool reacts); find recipes that taste the same at bigger sizes.
Grade 7 · Math · LabPizza Physics
Is one 16-inch pizza more than two 10-inch ones? Measure and compare circles to settle classic food debates.
Grade 10 · Math · LabShadow Measure
Measure a flagpole with its shadow and a meter stick using similar triangles, then check with the real height.
Grade 1 · Science · LabVibration Station
