Every year, the moon moves 3.8 cm farther from Earth. In the 11th part of 22, classes use the distance formula. They determine the distance to the moon based upon given data and then graph Galileo spacecraft data to determine its movement.

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.

Students view a video that reviews Mendelian genetics. They discuss the Hardy-Weinberg Law and use Popsicle sticks to simulate genetic variations and ratios in offspring.

You know that liquid nitrogen turns into a gas at room temperature. Place some in a two-liter bottle for a physics demonstration of the ideal gas law. Beware, however; this is a dangerous demonstration! Not to mention that you may not...

Young scholars explore linear functions in a crime solving context. They collect and analyze data using linear equations, then interpret the slope and intercepts from a linear model.
