The Right Ratio of Rest: Proportional Reasoning

Who knew running a greenhouse required so much math? Amaze future mathematicians and farmers with the amount of unit conversions, ratio and proportional reasoning, and geometric applications involved by having them complete the...

Farming is full of mathematics, and it provides numerous real-world examples for young mathematicians to study. Here, we look at a cylinder-shaped storage silo that has one flat side. Given certain dimensions, students need to determine...

Investigate the fascinating, yet terrifying phenomenon of hurricanes from the safety of your classroom using this earth science unit. Focusing on developing young scientists' spacial thinking skills, these lessons engage learners in...

What do magnetic fields look like? The best way to learn about magnetic fields is to try identifying them for yourself. Scholars will understand the importance of magnetic fields after completing this experiment. The extension activities...

Disease prevention or designer babies? Use a set of slides to introduce the growing practice of preimplantation genetic diagnosis, or PGD. Teens read related articles and then break into groups to address different scenarios. Afterward,...

In a nose-cone to nose-cone competition, which rocket will prevail? Teams form rocket companies to design and build a rocket while competing against other teams in an economic challenge. The team that comes up with the best benefit/cost...

A cookie recipe is displayed as an example of proportional relationships, a clever way to introduce your chemists to stoichiometry! The steps of stoichiometry are listed, molar volume is explained, and then several stoichiometry problems...

Sal goes back to a look at the Adiabatic process in this chemistry video. He sets up a Carnot Cycle that occurs within an adiabatic process; meaning there is no transfer of heat. From that problem, Sal constructs Volume Ratios which is a...

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...

Students apply estimation strategies and proportional reasoning to determine a scale comparing the planetary bodies to Earth. They convert measurements of time and distance using scientific notation. Both the metric and customary units...
