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.
In this math activity, students conduct a strength test using modeling clay, creating their own stress vs. strain graphs, which they compare to typical steel and concrete graphs. They learn the difference between brittle and ductile materials and how understanding the strength of materials, especially steel and concrete, is important for engineers who design bridges and structures.
Though teachers usually caution students against using sentence fragments, Edgar Schuster's work demonstrates that professional writers often use fragments effectively. This lesson helps students understand that there are reasons that they can and should use sentence fragments to become effective writers.
Students learn about and experiment with the concept of surface tension. How can a paper clip "float" on top of water? How can a paper boat be powered by soap in water? How do water striders "walk" on top of water? Why do engineers care about surface tension? Students answer these questions as they investigate surface tension and surfactants.
Students are introduced to the respiratory system, the lungs and air. They learn about how the lungs and diaphragm work, how air pollution affects lungs and respiratory functions, some widespread respiratory problems, and how engineers help us stay healthy by designing machines and medicines that support respiratory health and function.
Students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the color change of the indicator. They review the concepts of pH and respiration and extend their knowledge to measuring the effectiveness of bioremediation in the environment.
Students explore how tension and compression forces act on three different bridge types. Using sponges, cardboard and string, they create models of beam, arch and suspension bridges and apply forces to understand how they disperse or transfer these loads.
Bridges come in a wide variety of sizes, shapes, and lengths and are found all over the world. It is important that bridges are strong so they are safe to cross. Design and build a your own model bridge. Test your bridge for strength using a force sensor that measures how hard you pull on your bridge. By observing a graph of the force, determine the amount of force needed to make your bridge collapse.
This activity s a student project to construct and test the load bearing capacity of a scale model bridge from toothpicks.
During interactive read-aloud sessions, students identify how an author conveys mathematical information about animals' sizes and abilities. They then conduct research projects focusing on the same mathematical concepts.
Students are presented with a brief history of bridges as they learn about the three main bridge types: beam, arch and suspension. They are introduced to two natural forces tension and compression common to all bridges and structures. Throughout history, and today, bridges are important for connecting people to resources, places and other people. Students become more aware of the variety and value of bridges around us in our everyday lives.
Students act as engineers to learn about the strengths of various epoxy-amine mixtures and observe the unique characteristics of different mixtures of epoxies and hardeners. Student groups make and optimize thermosets by combining two chemicals in exacting ratios to fabricate the strongest and/or most flexible thermoset possible.
As a culminating activity for "Slaughterhouse-Five", students make a compilation album (a CD with 6-8 tracks) that reflects their analysis, understanding, and reaction to the ideas in the novel "Slaughterhouse-Five".
This classroom lab is a guided practice for inquiry using brine shrimp as the subject to be investigated.
Imagine if vocabulary could come alive with the click of a button! Students create video posters to demonstrate knowledge of new economics vocabulary.
This chapter provides teachers with instructions to install a school weather station, and to build simple instruments to monitor weather conditions. Materials need to create a homemade weathervane include a two-liter soft drink bottle, a shallow metal pie pan, a plastic drinking straw, and a compass. Building an anemometer requires plastic cups, soda straws, a pencil with an unused new eraser on the end, a paper punch, and a thumbtack. Thermometers and a rain gauge must be purchased. A data table is included for estimating windspeed using the anemometer. The chapter includes research ideas that allow students to validate their instruments and test the predictive capability of resources such as the Farmer's Almanac. This resource is chapter 15 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The resource includes background information, teaching tips and questions to guide student discussion. This is chapter 15 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.
Students create brochures on the same topic as another piece of writing they have done, highlighting how shifting purposes and audiences creates changes in their strategies as writers.
Students are introduced to the concept and steps of the engineering design process and taught how to apply it. Students first receive some background information about biomedical engineering (aka bioengineering). Then they learn about material selection and material properties by using a provided guide. In small groups, students learn of their design challenge (improve a cast for a broken arm), brainstorm solutions, are given materials and create prototypes. To finish, teams communicate their design solutions through class poster presentations.
