Our Experiment Library contains hundreds of free experiments and lab activities designed to engage students in active learning. Search by subject, grade level, or topical keywords. Download editable student labs, teacher notes with setup instructions, SPARKvue or Capstone software configuration files, and more, all for free!
Magnetic Field Strength
Students use a magnetic field sensor to measure the magnetic filed at the center of a coil at five different current levels. Students plot magnetic...
Phase Change
Students will use a wireless temperature sensor to determine the affect of phase change on the temperature of a substance.
Buoyant Force
Students measure the upward force on a cylinder and the displaced volume as it is submerged in a fluid. They determine the relationship between...
Position, Distance, and Displacement
Students will explore and discover the difference between position, distance, and displacement using graphs of their own motion.
Rotational Dynamics
Students use hanging masses to apply torque to a rotating arm and measure its angular acceleration. After varying the torque, they experimentally...
Fruit Battery
Students will construct an electrochemical cell using common materials. They will explore how the voltage changes as the cells are connected...
Titration Curves
Students will use a pH sensor and a drop counter to explore the shape of a titration curve produced by a strong acid and a weak acid when titrated...
Properties of Ionic and Covalent Compounds
Students will use hardness, melting point, solubility, and conductivity to determine the bond type present in unknown substances.
What Factors Affect Dissolved Oxygen?
Students will use a dissolved oxygen sensor to determine how different factors affect the concentration of dissolved oxygen in water.
Volume of Breath
Students investigate how the amount of air moving in and out of the lungs changes with exercise.
