Practical science,
without the
physical laboratory.

Test ten everyday materials with a bar magnet and a horseshoe magnet to discover which are magnetic and which are not. Identify the property that all magnetic materials share.

Place three potato cylinders into hypotonic, isotonic, and hypertonic solutions and watch them swell or shrink over 30 simulated minutes. Then use dialysis tubing with iodine and Benedict's tests to discover why membranes are selectively permeable.

Build six classical compass-and-straightedge constructions on a virtual drafting surface — segments, perpendicular bisectors, angles, bisectors, and triangles. Discover the rules that make each one exact.

Classify nine unknown solutions using red and blue litmus paper, then extract a red cabbage indicator from scratch and test the same nine solutions to compare. Discover why some indicators reveal acid strength while others only tell you acid or base.

Discover the four hidden pigments inside a green leaf using paper chromatography. Apply a pigment spot, set up the solvent, watch the bands separate, and compute the Retention Factor (Rf) for each pigment — the same technique used in forensics and food science.

Investigate nine energy sources — solar, wind, hydro, geothermal, biomass, coal, oil, gas and nuclear — by their availability, environmental impact and production consistency, then sort each into renewable or non-renewable. Grounded in Kenya's own clean-energy story.

Discover what makes a magnet special: dip a bar magnet in iron filings to see its force is strongest at the poles, watch a freely suspended magnet settle North–South like a compass, and find the rule for when magnets attract and when they repel.

Find any triangle's area without ever measuring its height. Slide two sides and the angle between them to watch Area = ½·a·b·sin C come alive, then switch to Heron's formula to get the area from three sides alone — and finish by costing a real triangular plot in shillings.

Build atoms with the Bohr model. Pick an element (Z = 1–20) from the periodic table, watch its nucleus of protons and neutrons form, set the electron shells, and place electrons under the 2, 8, 8 rule — then read off its configuration, period, group and valence, and test yourself with an 8-question quiz.
