34b. Wartime Diplomacy
Unrestricted Use
CC BY
Rating
0.0 stars

Rebellions rarely succeed without foreign support. The North and South both sought British and French support. Jefferson Davis was determined to secure such an alliance with Britain or France for the Confederacy. Abraham Lincoln knew this could not be permitted. A great chess match was about to begin.

Break the Tension
Read the Fine Print
Educational Use
Rating
0.0 stars

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.

Creating Mini Wastewater Treatment Plants
Read the Fine Print
Educational Use
Rating
0.0 stars

Student teams design and then create small-size models of working filter systems to simulate multi-stage wastewater treatment plants. Drawing from assorted provided materials (gravel, pebbles, sand, activated charcoal, algae, coffee filters, cloth) and staying within a (hypothetical) budget, teams create filter systems within 2-liter plastic bottles to clean the teacher-made simulated wastewater (soap, oil, sand, fertilizer, coffee grounds, beads). They aim to remove the water contaminants while reclaiming the waste material as valuable resources. They design and build the filtering systems, redesigning for improvement, and then measuring and comparing results (across teams): reclaimed quantities, water quality tests, costs, experiences and best practices. They conduct common water quality tests (such as turbidity, pH, etc., as determined by the teacher) to check the water quality before and after treatment.

Rating
0.0 stars

In this activity, students will use cookies to simulate the distribution of our nonrenewable resources (energy). Then, they will discuss how the world's growing population affects the fairness and effectiveness of this distribution of these resources and how engineers work to develop technologies to support the population.

0.0 stars

Students will brainstorm ways that they use and waste natural resources. Also, they will respond to some facts about population growth and how people use petroleum. Lastly, students will consider the different ways that engineers interact with and use our natural resources.

Rebuilding Soil with Biochar
Read the Fine Print
Educational Use
Rating
0.0 stars

Students learn about soil properties and the effect biochar—charcoal used as a soil amendment—has on three soil types, sand, loam and clay. They test the soils’ water retention capability before and after the addition of biochar. During the activity, student teams prepare soil mixtures, make observations (including microscopic examinations), compare soil properties, conduct water retention tests, take and record measurements, and analyze their observations and data. They see how the physical properties of soils—color, texture, and particle size—can be indicators of nutrient content and water retention capabilities to support plant growth. From their findings, they consider biochar’s potential benefits for environmental and agricultural applications, especially in conditions of drought and depleted soils. An activity lab sheet is provided to guide experimental data collection and analysis.

Rating
0.0 stars

In this lesson, students are introduced to the types of renewable energy resources. They are involved in activities to help them understand the transformation of energy (solar, water and wind) into electricity. Students explore the different roles of engineers working in renewable energy fields.

Tracing Fluorescent Plastics in an Aquatic Environment
Read the Fine Print
Educational Use
Rating
0.0 stars

Student teams investigate the migration of small-particle plastic pollution by exposing invertebrates found in water samples from a local lake or river to fluorescent bead fragments in a controlled environment of their own designs. Students begin by reviewing the composition of food webs and considering the ethics of studies on live organisms. In their model microcosms, they set up a food web so as to trace the microbead migration from one invertebrate species to another. Students use blacklights and microscopes to observe and quantify their experimental results. They develop diagrams that explain their investigations—modeling the ecological impacts of microplastics.

Viking Ship Design Challenge
Read the Fine Print
Educational Use
Rating
0.0 stars

In this design challenge, students learn about the Vikings from an engineering point-of-view. While investigating the history and anatomy of Viking ships, they learn how engineering solutions are shaped by the surrounding environment and availability of resources. Students apply this knowledge to design, build and test their own model Viking ships.
