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...

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...

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...

Learners work collaboratively to gain a better understanding of the vastness of space by scaling down the solar system. They measure by inches, gain an understanding of space, and model the distances of the planets from the sun.

In this chemical compounds instructional activity, students learn the steps for determining the empirical formula of a compound and then complete 3 problems.

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

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...

In this counting atoms in a molecule worksheet, students read about the molecule propanal that was discovered by the giant radio telescope in the Milky Way Galaxy. Students solve 6 problems where they find the number of atoms in the...

Students design and build a snowplow using LEGO materials. They compete in an Engineer's Challenge to clear a path through Styrofoam peanuts.

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...

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...

In this stoichiometry learning exercise, students review definitions and equations associated with molarity, density, atomic mass, molarity, and dilutions. This learning exercise has 18 word problems.

Students conduct an experiment in which a solution of copper(II) sulfate is added to iron filings. They write and balance the equation for the reaction that occurs and calculate the amount of iron that reacted and the percent yield of...

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.

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

Students map data on employment in wood products manufacturing in Oregon counties. In this Oregon forest instructional activity, students discover the percentage of people employed in the forest manufacturing industry. Students create a...

Students observe and discuss cloud cover. They identify percent of cloud cover, calculate cloud cover by fraction and convert to a percent, and compare their models with the current real sky cloud cover.

Pupils conduct an experiment to determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.
