Mathematics virtual labs
Simulated experiments, instruments and processes built on real scientific rules. Each lab has an aim, steps, tasks and exam questions, and links to the topics it supports.
ExplorerIndex Laws ExplorerJoin and cancel blocks to see why aᵐ × aⁿ = aᵐ⁺ⁿ, aᵐ ÷ aⁿ = aᵐ⁻ⁿ and (aᵐ)ⁿ = aᵐⁿ, and use a graph of 2ˣ to see zero, negative and fractional powers.Open →ExplorerNumber SorterDrag numbers such as √9, √10, 0.3̇, −4 and π into the smallest set they belong to: natural, whole, integer, rational or irrational.Open →ModelRounding and BoundsSee the interval a rounded measurement could have come from, drag a true length across the bounds, and find the smallest and largest area of a rectangle.Open →ExplorerStandard Form ScaleSlide along a powers-of-ten scale from an atom to the Milky Way, and see each size in ordinary and standard form.Open →ExplorerZoom into the Number LineZoom into the number line ten times at a time to find the digits of √2, π and 1/7, and see where 22/7 and 1.414 stop matching.Open →
How the labs work
Each lab copies a real experiment, measuring instrument or natural process. The numbers come from the real scientific rules, and any simplification is stated under the lab.
