Curated OER
Exploring Buoyancy
Young scholars use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will...
Curated OER
Free Up the Ketchup!
Students, in teams, use given materials and their knowledge of Newton's First Law to create a device that will remove a sticky ping pong ball from a 16-oz. cup (which represents ketchup stuck in a bottle.)
PBS
Robo Arm
Future engineers create robotic arms like those on rovers built by NASA in the second activity of the series. They test their devices by attempting to pick up and move cups to a specified location.
Nature
Structural Hazards
The scientific explanation of seismic waves is detailed in the introduction. A fictional scenario is also provided for your class to discuss. Pictures and handouts that are meant to be included, however, they are not accessible....
Curated OER
Earthquake
Students view a video and conduct a problem solving activity to explain the effect different waves have on the earth's structure and what effect they have on different structures.
Curated OER
Skyscrapers
Students engineer their way through a hands-on science activity. In this architecture lesson, students examine dead loads and wind loads as they participate in the Skyscraper Challenge.
Curated OER
Straw Shapes
Students view a video on bridges and domes. They discuss the importance of shapes, especially triangles for these structures. They participate in an activity in which they create their own dome out of paper clips.
Curated OER
Lab for Truss Design and Testing
Students design and build their own truss. In this physics lesson, students calculate the forces and maximum load. They complete a full scale diagram of their design.
Curated OER
Earthquake Proof Structures
Eighth graders build a structure that is able to withstand a simulated earthquake. They research earthquakes, earthquake measurement, and society's preparation for and reaction to them. Pupils build models and present them to the...
Curated OER
Determining Beam Stress and Deflection with COSMOSXpress
Students analyze cantilever stress using COSMOSXpress. In this engineering lesson plan, students calculate the beam's maximum deflection. They investigate the effect changing beam dimensions.
Curated OER
Types of Forces
Students study scientific names and descriptions of forces. In this motion lesson students organize information into a graphic organizer then teach it to other students.
Curated OER
Science: Avalanche!
Eighth graders examine avalanches after reading excerpts from John Muir's book, "The Yosemite." In small groups, they conduct experiments with flour, sugar, and potato flakes representing different snow consistencies. Then, 8th graders...
Curated OER
Model Storage Facility
Students design a storage facility that can withstand extreme wind loads. In this physics activity, students decide how to build their facility considering budget constraints. They evaluate their design and present it to class.
Curated OER
Cytoskeleton of a Cell
Students examine the cytoskeleton of a cell. They work together to build a structure with a certain number of materials. They share their "cell" with their classmates.
Curated OER
Earthquake Crossword
In this earth science worksheet, learners find the words that are related to earthquakes. The answers are found at the bottom of the page.
Curated OER
Avalanche!
Middle schoolers explain that when forces on an object are balanced, the motion of object does not change. They describe how an object changes its motion when forces on it are unbalanced. They plan and conduct a scientific investigation...
Curated OER
Daphnia and Algae: A Study of Pond Dynamics
Students observe interrelationships and interdependencies of organisms which may generate stable ecosystems. They also study that living organisms have the capacity to produce infinite sized populations, but environments and resources...
Curated OER
Design & Technology: Materials Strength
Students investigate the function of a floor stretcher and some of the past designs. The goal is to improve the design durability and ease of use. Then they sketch their ideas and write a rationale for changes made to the structure.
