Chemistry stars experiment with metals to observe reactivity with salt solutions. They test magnesium, zinc, iron, and copper by immersing them into different solutions and observing for changes. A separate set of data tables is...

Don't overreact! A simple experiment demonstrates chemical reactions as scholars mix chemical solutions and metals in a large well plate. They note all changes to the metals, solutions, precipitate, colors, and more. A full data table...

Snow, ice, and water are all composed of H2O. Does that mean they all have the same volume? Discover the ways that the densities of these substances determine their volumes, and how they change based on their current states of...
