Can Photosynthesis Occur at Saturn?
In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

Modeling Sizes of Planets
The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Is There Salt in a Glacier?
What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts.
