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...

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...

High schoolers 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.

Studets practice problem solving and comparison of quantities, ratios and prproportions. They develop a plan for determining the height of a flagpole complete with drawings and calculations. In addition, they complete a written...

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...

Aspiring astronomers solve problems involving mixed units of the same attribute, including time, money, length, and area. They convert large numbers into scientific notation, then compute and compare ratios to explain why drawing...

Students conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain how...

Students examine and compare traits of humans and crocodiles.  For this crocodile lesson students use a ratio to estimate the height of a person and compare that to a crocodile. 

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Students explain why a transiting planet causes a periodic dimming in the light from its parent star. They determine the radius of a planet, and its orbital distance, by analyzing data and manipulating equations. Students compare the...

Avoiding lab safety rules will not give you super powers. The lesson plan 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 mixture and...

Learners map data on employment in wood products manufacturing in Oregon counties. In this Oregon forest lesson, students discover the percentage of people employed in the forest manufacturing industry. Learners create a box and whisker...

Students explore types of water reserves. In this water conservation lesson, students brainstorm ways water are used in their homes. Students use a graduated cylinder to simulate the amount of water on Earth and the amount that humans use.

Students explore the nature of the air we breathe by observing petri dishes that have accumulated particulate matter from the atmosphere. Students make mathematical calculations and inferences about the effect of this matter on...

Third graders discuss light sources and collect data about energy sources. They compare data and create a multiple line graph showing energy used by light sources for each student in the group. They present their graphs and write a...

Pupils study the formulas for calculating heat energy and how to convert Celsius to Fahrenheit. They apply the formulas on a worksheet.
