Heat Transfer Lesson

(View Complete Item Description)

Students explore heat transfer and energy efficiency using the context of energy efficient houses. They gain a solid understanding of the three types of heat transfer: radiation, convection and conduction, which are explained in detail and related to the real world. They learn about the many ways solar energy is used as a renewable energy source to reduce the emission of greenhouse gasses and operating costs. Students also explore ways in which a device can capitalize on the methods of heat transfer to produce a beneficial result. They are given the tools to calculate the heat transferred between a system and its surroundings.

How vaccines train the immune system in ways no one expected | Christine Stabell Benn | TEDxAarhus

(View Complete Item Description)

Vaccines do much more than protect against the disease they are designed for. Watch this talk from TEDxAarhus 2018 by medical doctor and professor in global health Christine Stabell Benn and learn how hundreds of thousands of lives could be saved every year just by using the existing vaccines smarter. Christine Stabell Benn is a medical doctor and professor in global health. By studying real-life effects of vaccines in Africa, she has found that vaccines do much more than protect against the target disease; they have so-called non-specific effects. In most cases, they come with an added bonus of increased resistance against other infections than the target disease. If we take that into account, we can save hundreds of thousands of lives every year just by using the existing vaccines smarter. Christine argues that we should not only study vaccines' effects on the target infection, but also ask the often ignored question: what is the impact of vaccines on overall health?

Getting Started with Rust by Building a Tiny Markdown Compiler

(View Complete Item Description)

This is an introductory Rust tutorial for developers who like learning by doing. The purpose of this tutorial is to develop intuition about toolbuilding in Rust–specifically, to learn how to think and build in Rust. Our goal is to produce a very basic command line compiler that will turn a basic Markdown document containing headings and paragraphs into an html file. To do this, we will start from scratch by building a simple “Hello, World!” executable. Then, over the course of six chapters, iterate and expand until finally we can compile a very simple Markdown file into valid HTML.

Above-Ground Storage Tank Design Project

(View Complete Item Description)

At this point in the unit, students have learned about Pascal's law, Archimedes' principle, Bernoulli's principle, and why above-ground storage tanks are of major concern in the Houston Ship Channel and other coastal areas. In this culminating activity, student groups act as engineering design teams to derive equations to determine the stability of specific above-ground storage tank scenarios with given tank specifications and liquid contents. With their floatation analyses completed and the stability determined, students analyze the tank stability in specific storm conditions. Then, teams are challenged to come up with improved storage tank designs to make them less vulnerable to uplift, displacement and buckling in storm conditions. Teams present their analyses and design ideas in short class presentations.

What Is the Design Process?

(View Complete Item Description)

This video segment, adapted fromThinking Big, Building Small, demonstrates each part of the engineering design process, which is fundamental to any successful project. Though it does this in the context of building skyscrapers, the process is applicable to any sort of project, including constructing schools, building bridges, and even manufacturing sneakers. Students will recognize the value of going through its steps sequentially when constructing scale models. Recommended for: Grades 3-12

Here Comes the Hurricane! Saving Lives through Logical Reasoning and Computer Science

(View Complete Item Description)

Students use a hurricane tracking map to measure the distance from a specific latitude and longitude location of the eye of a hurricane to a city. Then they use the map's scale factor to convert the distance to miles. They also apply the distance formula by creating an x-y coordinate plane on the map. Students are challenged to analyze what data might be used by computer science engineers to write code that generates hurricane tracking models. Then students analyze a MATLAB® computer code that uses the distance formula repetitively to generate a table of data that tracks a hurricane at specific time intervals. Students come to realize that using a computer program to generate the calculations (instead of by hand) is very advantageous for a dynamic situation like tracking storm movements. Their inspection of some MATLAB code helps them understand how it communicates what to do using mathematical formulas, logical instructions and repeated tasks. They also conclude that the example program is too simplistic to really be a useful tool; useful computer model tools must necessarily be much more complex.

Facial Recognition/Artificial Intelligence

(View Complete Item Description)

Asking the question, “What is human-computer interaction - artificial intelligence? Students come to understand what artificial intelligence is in most everyday life, discussing the privacy, pros and cons of this topic and exploring with artificial intelligence activities online. This lesson plan includes using the Google Vision Kit to explore various pre-loaded facial recognition programs and advance programming students can access the Python code, manipulate the code and test the changes.

Great Writers Inspire: Early Modern Drama on the Page and Stage

(View Complete Item Description)

Many books and university courses, trying to compensate for a history of the neglect or mistrust of plays as performance, use the phrase "from page to stage" to think about the dramatic possibilities of their texts. In fact, for the early modern theatre, the phrase needs to be the other way around--from stage to page. Plays were performances first, and only later, and then only sometimes, books. This section of Great Writers gathers resources--podcasts, eBooks, websites--to explore the two interconnected lives of the early modern play--as an event in time and space on the stage of the Globe or Blackfriars theatre, and as a material printed object, on sale to Elizabethan and Jacobean readers in the booksellers' quarter around St Paul's Churchyard.
