Students explore acid-base titrations, where the goal is to determine how much solution must be added to the flask to neutralize the mixture.
Students identify the real gold medal from an inexpensive copy and determine if an Olympic gold medal is actually made of gold by investigating the density of different metals.
Students use the Beer‑Lambert law to observe the relationship between concentration, absorbance, and percent transmittance using multiple solutions.
Students can change what happens in the video, selecting and varying a parameter like acid-base combination or indicator, and observe how these changes affect the outcome.
Students explore Le Chatelier’s principle to understand the equilibrium equation and constant for reactions.
Students use the concept of buoyancy along with a clever method for determining the density of objects.
