Intensity of Light
Students measure the intensity of a light source vs distance. Using their data they explore the mathematical relationship between intensity and distance...
Varying Reaction Rates
Students will use a wireless temperature link with a fast response temperature probe to investigate how different temperatures affect the rate of a chemical...
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. From this...
Phase Change
Students will use a wireless temperature sensor to determine the effect of phase change on the temperature of a substance.
Ohm's Law
Students measure the current and voltage across a resistor while varying the output voltage, A graph of voltage versus current will reveal Ohm's Law. This...
Fermentation
Students use an ethanol sensor to determine the ability of yeast to use different types of carbohydrates—sucrose and starch—for fermentation.
Titration Curves
Students will use a pH Sensor and a Drop Counter to explore the shape of a titration curve produced by the titration of a strong acid and a weak acid by...
Properties of Ionic and Covalent Compounds
Students will use hardness, melting point, solubility, and conductivity to determine the bond type...
What Factors Affect Dissolved Oxygen?
Students will use a dissolved oxygen sensor to determine how different factors affect the concentration...
Plant Respiration and Photosynthesis
Students use a carbon dioxide sensor to measure the rates of photosynthesis and respiration in spinach leaves.
