Engineering Simple Machines
Simple Machines: How Levers and Pulleys Change the Effort
Compare lever and pulley designs with fair tests. Explain how a lower effort can require a greater movement distance, and improve a lifting design using measurements.

Matter
Particles Too Small to See
Use models and observable evidence to explain that matter can be made of particles too small to see directly.
55 min · ~10 min prep · 7 materials
Matter & Properties
Acids & Bases: Properties, Indicators & pH
Use safe indicator evidence to compare acidic, neutral, and basic solutions and interpret the pH scale without relying on taste or touch.

Matter
Conservation of Matter
Measure the same complete setup before and after matter changes form or mixes, then use the data to explain what stayed the same and why a scale reading can change when matter leaves what is being measured.

Matter
Physical & Chemical Changes
Compare a familiar physical change with evidence from a safe mixing investigation. Record before-and-after properties, use more than one observation, and make a careful claim about whether new substances formed.

Matter
Mixtures & Solutions: Dissolve, Separate & Recover Matter
Compare mixtures and solutions, use material properties to choose separation methods, and use recovery evidence to decide whether mixing formed a new substance.

Forces & Gravity
Gravity Pulls Toward Earth
Use observations, diagrams, and models to support an argument that Earth's gravitational force pulls nearby objects toward Earth's center.

Motion & Measurement
Speed Experiment: Measure Distance, Time & Motion
Measure how long a cart takes to travel a fixed distance, calculate average speed, and use repeated trials to test how one change in a ramp setup affects motion.
