Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

NASA presents a mini-unit on distances in our solar system. It incorporates scientific concepts of gravity, mass, density, and payload while your aspiring astronauts also employ mathematics skills. They calculate speed, they determine...

Stoichiometry sounds complicated, but it really means the study of the amount of substances involved in a reaction. The sixth lesson in an 11-part series has scholars use stoichiometry to find the theoretical yield of a reaction. Then,...

Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-lesson worksheet to help focus pupils on the task at hand. 

Try not to blind anyone with science by following the safety rules. The lesson encourages scholars to form an ionic compound from magnesium and chlorine. Then they determine the empirical formula and determine the mole ratio and percent...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

How much plastic do manufacturers use to create water bottles each year? The class explores the number of water bottles used throughout the years to determine how many consumers will use in the future. Class members compare different...

Pairs simulate the energy usage of different countries by drawing beads from a bag, which contain different beginning ratios of non-renewable and renewable energy resources. The activity concludes with a series of questions to tie...

Avoiding lab safety rules will not give you super powers. The instructional activity opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a...

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

Students see how NASA scientists are studying the circadian timing system to improve astronaut's physical and mental tasks while working in space. They demonstrate how fractions, decimals, and percents are related.
