We’ve discussed the four main branches of engineering but there are so many other fields doing important work, so today we’re going to explore a few of them. In this episode we’ll explore some of the history and fundamentals of industrial engineering, biomedical engineering, and bioengineering.
The history of science up until the Cold War is often overshadowed by the Manhattan Project. But, today we are going to talk about advances in biomedicine, or healthcare based on a biological understanding of human bodies and diseases.
This lithograph shows the break-off of a large iceberg from the Pine Island Glacier in West Antarctica. This event occurred between November 4th and 12th, 2001, and provides powerful evidence of rapid changes underway in this area of Antarctica. The three images presented were acquired by the vertical-viewing (nadir) camera of the Multi-angle Imaging SpectroRadiometer (MISR) instrument aboard NASA's Terra spacecraft.
Science Background:
Most nonpermanent markers use inks that are made of colored pigments and water. On a coffee filter, the water in the ink carries the pigment onto the paper. When the ink dries, the pigment remains on the paper.
When you dip the paper in water, the dried pigments dissolve. As the water travels up the paper, it carries the pigments along with it. Different-colored pigments are carried along at different rates; some travel farther and faster than others. How fast each pigment travels depends on the size of the pigment molecule and on how strongly the pigment is attracted to the paper. Since the water carries the different pigments at different rates, the black ink separates to reveal the colors that were mixed to make it.
Chromatography is one of the most valuable techniques biochemists have for separating mixtures. It can be used to determine the ingredients that make up a particular flavor or scent, to analyze the components of pollutants, to find traces of drugs in urine, and to separate blood proteins in various species of animals (a technique that's used to determine evolutionary relationships).
Learning Outcome HB5.2 - Investigate the structure, function, and major organs
of one or more human body systems such as the digestive, excretory,
respiratory, circulatory, nervous, muscular, and skeletal systems. [SI, TPS]
Goal: Identified areas of the Science 5 curriculum where student development of
models of scientific concepts would be appropriate.
BrainPOP invites students to discover, play and create, enriching and deepening their understanding of topics across the curriculum. Children are encouraged to make movies out of images, build maps and develop their block-based coding skills. BrianPOP Jr. targets children from 0 to 3 whereas BrainPOP focuses on K-12 grade children.
This collection of activities is based on a weekly series of space science problems distributed to thousands of teachers during the 2009-2010 school year. They were intended for students looking for additional challenges in the math and physical science curriculum in grades 9 through 12. The problems were created to be authentic glimpses of modern science and engineering issues, often involving actual research data. The problems were designed to be åÔone-pagersåÕ with a TeacheråÕs Guide and Answer Key as a second page. This compact form was deemed very popular by participating teachers.
Welcome to CAST Science Writer, the tool that supports students in writing lab and class reports. This tool is geared toward middle school and high school students.
Science Writer is an interactive, web-based instructional learning tool designed to help students in writing a complete science report; it supports students throughout the process of writing a science report. Research has revealed several effective instructional practices in improving the written language performance of students, and Science Writer has been designed to provide these:
- A breakdown of the report writing process into manageable components
- Scaffolds for each step of the writing process
- an organizational structure for report writing
- Sentence starters to help initiate the writing
Science Writer is a technology-based learning environment that can provide plentiful opportunities for practice—a critical element to successful reading or writing strategy instruction. Science Writer enables students to demonstrate their knowledge of science concepts through writing, structures the writing processes as it relates to content-area writing, structures the thought process required for scientific writing, provides opportunities for structured practice and utilizes the Universal Design for Learning (UDL) Framework to meet the needs of a wide range of students. Science Writer's Agent characters, Max, Sam and Eko, provide tailored support. Max and Sam give students a model and the reasoning behind it, and Eko gives students specific hints on how to progress. Additional support and tools are detailed throughout this manual.

Students use washable paints, markers, and construction paper to illustrate a month from the traditional Cree Calendar
Students will be able to:
illustrate a month from the traditional Cree calendar;
demonstrate an understanding of the changes, cycles and patterns that occur in nature through words and images;
draw/paint geometric and organic shapes;
create the illusion of depth in space using size;
connect personal life experiences to their artworks.
The Canadian Space Agency site has lots of fun stuff for students including fun experiments, fun stuff, podcasts, quizzes and more.
This awesome science video outlines how and why engineers ask themselves "what-if" questions as they identify variables in the solutions to the problems they are working on.
Until roughly 1100, there were relatively few places of knowledge-making. Monasteries and abbeys had special rooms called scriptoria where monks copied manuscripts by hand. But the biggest places where knowledge was made were the Gothic cathedrals. Then Universities came along, too. This is the story of those two institutions!
The Celestia Motherlode is a repository for various addons like textures, models or celestial objects for Celestia. Celestia is a free, interactive (real-time), 3D astronomy program. It doesn't just show you the sky as it can be seen from earth as most planetarium software does, but allows you to move to and view the universe from any point between the planets and the stars. The Celestia Motherlode hosts over 10 GB of Celestia addons by various creators, which extend or change the way Celestia renders the universe.
Engineering, like life, could really use a lot more cheese. This week we are looking at a cheese factory in Toronto and what it can teach us about process control systems. We’ll explore feedforward and feedback systems, and see how integrating them both with the final check of cascade control creates a system made to handle uncertainty the world throws its way.
We've talked about mixtures and solutions, solutes and solvents, but what about things that can't be undone? What about Chemical Changes? Would it surprise you to know that baking a cake is a Chemical Change? Or striking a match? In this episode of Crash Course Kids, Sabrina talks to us about how to tell if you have a chemical change on your hands.

Hank introduces us to ourselves by taking us on a journey through the fascinatingly diverse phyla known as chordata. And the next time someone asks you who you are, you can give them the facts: you're a mammalian amniotic tetrapodal sarcopterygian osteichthyen gnathostomal vertebrate cranial chordate.
