This unit is designed for advanced programming classes. It leads students through a study of human vision and computer programming simulation. Students apply their previous knowledge of arrays and looping structures to implement a new concept of linked lists and RGB decomposition in order to solve the unit's Grand Challenge: writing a program to simulate peripheral vision by merging two images. This unit connects computer science to engineering by incorporating several science topics (eye anatomy, physics of light and color, mathematics, and science of computers) and guides students through the design process in order to create final simulations.

Create 3D printed components for a vegetable/fruit STEM racer!

From the article:

"These 3D printed STEM race cars are the perfect project based learning tool to help teachers get kids excited about science, technology, engineering, math, and nutrition to boot! The racers I show you how to make in this instructable will provide an opportunity to turn almost anything (no kittens or other live things please) into a race car – allowing different sized and weighted objects to illustrate mechanical physics concepts like mass, friction, force, speed, distance, and gravity!"

With sustainability goal 10, reduced inequalities, we wanted to research inequality through different mediums. We felt that when most people hear inequality, they immediately think of wealth and class differences. While we did explore that, we also wanted to expand from those and explore inequality by how it affects one's safety, if security is dependent on wealth, also access to resources, a focus on mental health and physical wellness, as well what we can see visually and how that it in itself has a negative rippling effect.

This course provides a review of physical, chemical, ecological, and economic principles used to examine interactions between humans and the natural environment. Mass balance concepts are applied to ecology, chemical kinetics, hydrology, and transportation; energy balance concepts are applied to building design, ecology, and climate change; and economic and life cycle concepts are applied to resource evaluation and engineering design. Numerical models are used to integrate concepts and to assess environmental impacts of human activities. Problem sets involve development of MATLABĺ¨ models for particular engineering applications. Some experience with computer programming is helpful but not essential.

You may have heard it called pot, weed, grass, ganja or skunk, but marijuana by any other name is still a drug that affects the brain. Did you know marijuana can cause some people to lose focus on events around them? It makes others more aware of their physical sensations, and it has still more effects on other people. All these different changes are caused by chemicals that affect the brain. More than 400 chemicals are in the average marijuana plant. When smoked, heat produces even more of them!

Repeated motion is present everywhere in nature. Learn how to 'make waves' with your own movements using a motion detector to plot your position as a function of time, and try to duplicate wave patterns presented in the activity. Investigate the concept of distance versus time graphs and see how your own movement can be represented on a graph.

What happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to explore the role of water.

Wetlands have come under significant pressure in recent decades, resulting in the loss of many wet ecosystems around the world and across climatic zones. Despite this loss, wetlands have received significantly less attention than other ecosystems such as forests or coral reefs, resulting in a lack of public awareness. Wetland ecosystems currently provide livelihoods to more than one billion people, support up to 40% of all species, and act as large carbon stores. This poster illustrates the underlying causes for the decline in wetlands, the resulting consequences for physical and social systems as well as possible solutions to this problem.

In this video segment adapted from NOVA scienceNOW, learn about engineering innovations that could help detect a bridge's structural weaknesses before they become dangerous.

Hundreds of scientific articles. Written for middle and high school students. Approved by scientists. Free.

Short Description:
This text is a presentation of how and why children grow, develop, and learn. We will look at how we change physically over time from conception through middle childhood. We examine cognitive change, or how our ability to think and remember changes over the first few stages of life. And finally, we will look at how our emotions, psychological state, and social relationships change throughout childhood.

A 15-year-old girl presented to our institution with headache, vomiting, and nausea of 3-week duration. Physical examination showed no focal neurologic deficits. The patient's past medical, surgical, and family histories were all noncontributory.

This activity is a classroom investigation where the students create, in size and distance, a solar system model in proportion to a selected sphere representing the earth.

In this adapted ZOOM video segment, cast members calculate how much water they each use during a typical shower. They compare their results to their original predictions.

This is a book containing over 200 problems spanning over 70 specific topic areas covered in a typical Algebra II course. Learners can encounter a selection of application problems featuring astronomy, earth science and space exploration, often with more than one example in a specific category. Learners will use mathematics to explore science topics related to a wide variety of NASA science and space exploration endeavors. Each problem or problem set is introduced with a brief paragraph about the underlying science, written in a simplified, non-technical jargon where possible. Problems are often presented as a multi-step or multi-part activities. This book can be found on the Space Math@NASA website.

In this lesson, students are introduced to audio engineers. They discover in what type of an environment audio engineers work and exactly what they do on a day-to-day basis. Students come to realize that audio engineers help produce their favorite music and movies.

Students learn about the fundamental concepts important to fluid power, which includes both pneumatic (gas) and hydraulic (liquid) systems. Both systems contain four basic components: reservoir/receiver, pump/compressor, valve, cylinder. Students learn background information about fluid power—both pneumatic and hydraulic systems—including everyday applications in our world (bulldozers, front-end loaders, excavators, chair height lever adjustors, door closer dampers, dental drills, vehicle brakes) and related natural laws. After a few simple teacher demos, they learn about the four components in all fluid power systems, watch two 26-minute online videos about fluid power, complete a crossword puzzle of fluid power terms, and conduct a task card exercise. This prepares them to conduct the associated hands-on activity, using the Portable Fluid Power Demonstrator (teacher-prepared kits) to learn more about the properties of gases and liquids in addition to how forces are transmitted and multiplied within these systems.
