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!
Blockly Extension: pH
In this activity, students create a Blockly program that displays a solution's pH alongside a text description of the solution (base, acid, or...
Blockly Extension: Chemical Reactions
In this activity, students develop a Blockly program that determines whether a chemical change is occurring using temperature readings.
Transistor as an Amplifier
Students investigate the properties of a transistor with current and voltage sensors. They use their observations to describe the behavior of...
Properties of Diodes
Students investigate the properties of a diode with current and voltage sensors. They use their observations to describe the behavior of a diode.
Newton's Second Law
Students measure the force on a cart and its resulting acceleration for a modified Atwood machine. They vary the weight on the hanger and create...
Intensity of Light
Students measure the intensity of a light source vs distance. Using their data they explore the mathematical relationship between intensity and...
Ohm's Law
Students measure the current and voltage across a resistor while varying the output voltage. A graph of voltage vs current will reveal Ohm's...
Varying Reaction Rates
Students will use a wireless temperature link with a fast response temperature probe to investigate how different temperatures affect the rate...
Change in Kinetic Energy
Students measure the force from the Smart Fan, then investigate the relationship between the change in kinetic energy and the distance traveled....
Tunnel Demonstration
This demonstration shows that the ball can be caught by the cart even if the cart passes through a tunnel while the ball is in the air. The tunnel...
