Breaking Beams

As a more personal part of a unit on brain chemistry, your class discusses stressful situations and the body's response to them. They talk about how, while the reactions are initially helpful, some can be harmful to your health. Finally,...

After this video, make sure to give a pop quiz on pimples! The question that is answered is whether or not pimples are caused by stress. Stress hormones give our bodies what we need for a fight or flight, but what happens if we don't do...

Students learn about stress and strain by designing and building beams using polymer clay. They compete to find the best beam strength to beam weight ratio, and learn about the trade-offs engineers make when designing a structure.

What makes a clock tick or a bulb light up? The concept of work is explained to a backdrop of clever animation. Physics fans learn that the amount of work equals the product of the force and distance, and that the rate equals the amount...

Students learn about contact stress and its applications in engineering. They are introduced to the concept of heavy loads, such as buildings, elephants, people and traffic, and learn how those heavy loads apply contact stress. Through...

Students investigate the three types of material stress related to rocks. They identify the three types of stress, conduct a simulation by breaking bars of soap using only their hands, and complete a worksheet.

Students explore stress and strength in engineering design. In this engineering lesson, students become familiar with terminology associated with stress and strain on building material. They will have a class discuss about how their beam...

Students think like agricultural engineers as they perform a play about Integrated Pest Management at an apple orchard. [12:15]

Is an I-beam as strong as a solid beam of the same size? What if you include weight in the comparison: which beam has the greater strength-to-weight ratio? Would an I-beam be stronger than a solid rectangular beam of the same weight?...

In this activity learners explore earth-friendly materials that can be used in home environments. They learn about the relationship between the environment and design, and use a variety of problem-solving strategies. They work in...
