🔬
Investigating Forces
Learn to measure forces with a newton-meter and design a fair test, from variables to results tables and conclusions.
📐
Ohm's Law
Master the equation at the heart of electronics, V = I × R, and learn to rearrange it to find voltage, current, or resistance in any simple circuit.
📈
Scatter Plots and Correlation
Plot two variables against each other, name the correlation as positive, negative, or none, and draw a line of best fit to make honest predictions.
📈
Graphing Equations
See how linear equations draw straight lines — and what slope and y-intercept really mean — then meet the U-shaped curves that quadratics make.
❌
Systems of Equations
Two equations, one answer that satisfies both. See why the point where two lines cross solves both equations at once, and read solutions from a graph.
🧮
Rearranging Formulas
Make any variable the subject. Use inverse operations to rearrange formulas until the letter you actually want stands alone.
🌦️
How Weather Forecasting Works
How a modern forecast is built: from barometers and folklore to a global sensor network, supercomputers solving the atmosphere as equations, and the chaos that limits how far ahead we can ever see.
🔢
Algebra Essentials
Solve equations, graph lines, and crack quadratics: the core of algebra.
➗
Pre-Algebra
Master the bridge from arithmetic to algebra: integers, order, and variables.
