Students take a closer look at cars and learn about some characteristics that affect their energy efficiency, including rolling resistance and the aerodynamics of shape and size. They come to see how vehicles are one example of a product in which engineers are making changes and improvements to gain greater efficiency and thus require less energy to operate.

This short video and interactive assessment activity is designed to teach fourth graders about using the four operations with weights (english units).

This short video and interactive assessment activity is designed to teach fourth graders about solving two-step single-unit problems with four operations (metric units) - word problems.

This course explores the values (aesthetic, moral, cultural, religious, prudential, political) expressed in the choices of food people eat. Analyzes the decisions individuals make about what to eat, how society should manage food production and consumption collectively, and how reflection on food choices might help resolve conflicts between different values.

If you visited another world, you would notice a change in your weight, because the force of gravity acting on you there would be different from the force of gravity here on Earth.

This short video and interactive assessment activity is designed to teach fourth graders about greater or less than comparisons of length (english units).

Students learn about weight by building a spring scale and observing how it responds to objects with different masses.

Students learn about weight and drag forces by making paper helicopters and measuring how adding more weight affects the time it takes for the helicopters to fall to the ground.

This short video and interactive assessment activity is designed to give fourth graders an overview of complex weight problems (metric units).

Students learn more about forces by examining the force of gravitational attraction. They observe how objects fall and measure the force of gravitational attraction upon objects.

Students measure and analyze forces that act on vehicles pulling heavy objects while moving at a constant speed on a frictional surface. They study how the cars interact with their environments through forces, and discover which parameters in the design of the cars and environments could be altered to improve vehicles' pulling power. This LEGO® MINDSTORMS® based activity is geared towards, but not limited to, physics students.

This short video and interactive assessment activity is designed to give fourth graders an overview of metric units of weight.

This short video and interactive assessment activity is designed to give fourth graders an overview of comparison of weights (metric units).

This course serves as an introduction to the current research questions in phonological theory. Topics include metrical and prosodic structure, features and their phonetic basis in speech, acquisition and parsing, phonological domains, morphology, and language change and reconstruction. Activities include problem solving, squibs, and data collection.

In this course, we will explore what makes things in the world the way they are and why, to understand the science and consider the engineering. We learn not only why the physical world behaves the way it does, but also how to think with chemical intuition, which can’t be gained simply by observing the macroscopic world.
This 2018 version of 3.091 by Jeffrey Grossman and the 2010 OCW version by Don Sadoway cover similar topics and both provide complete learning materials. This 2018 version also includes Jeffrey Grossman’s innovative Goodie Bags, Why This Matters, and CHEMATLAS content, as well as additional practice problems, quizzes, and exams.

This activity can be conducted in the classroom. The students are given an opportunity to discover the basic concept of balance/counterbalance and how evenly distributed weight affects an object.

In this lesson, students discover the entire process that goes into designing a rocket for any customer. In prior lessons, students learned how rockets work, but now they learn what real-world decisions engineers have to make when designing and building a rocket. They learn about important factors such as supplies, ethics, deadlines and budgets. Also, students learn about the Engineering process, and recognize that the first design is almost never the final design. Re-Engineering is a critical step in creating a rocket.

This short video and interactive assessment activity is designed to teach fourth graders about length comparisons using data tables (english units).
