Following the steps of the engineering design process and acting as biomedical engineers, student teams use everyday materials to design and develop devices and approaches to unclog blood vessels. Through this open-ended design project, they learn about the circulatory system, biomedical engineering, and conditions that lead to heart attacks and strokes.

In this self-paced tutorial, educators learn about the kinds of educational experiences that prove effective in exciting students about STEM careers and identify resources that can be used to introduce students to STEM careers, especially those related to climate change science. Profiles of scientists and engineers representing diverse populations are included for use in the classroom. Multimedia educational resources including video clips and vocabulary words linked to a glossary are included. This is the eighth of ten self-paced professional development modules providing opportunities for teachers to learn about climate change through first-hand data exploration.

In this career-oriented interview, readers are introduced to the manager of several farmer's markets in Portland, Oregon. Following a brief description of his job and the general operations of a farmer‰Ûªs market, he explains why these venues are beneficial to the vendors, the customers and the environment. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

An interview conducted with a building contractor provides insights into what it means to build an environmentally "green" house. This lesson is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

This career-oriented interview features a home energy auditor. He describes his job responsibilities and offers tips for improving home energy efficiency. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

Using her countywide program as an example, a recycling educator offers incentives for recycling by providing data on energy savings and explaining how her county in Michigan supports the program. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

In this career-oriented interview, readers are introduced to a scientist who works primarily on wind energy. He explains the importance of wind farm placement planning. Images of architectural wind and a wind farm are included, along with a link to the Power Up game. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

A landscaper explains, through an interview format, how it is possible to design and maintain yards and gardens that require very little water. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

The article addresses this question by suggesting environmentally friendly actions to help reduce carbon footprints, trash production, and water usage. ‰ÛÏGreen‰Û� careers are also discussed. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

Accuracy of measurement in navigation depends very much on the situation. If a sailor's target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the island were only 1 km wide, it would be missed if off just the smallest bit. Many of the measurements made while navigating involve angles, and a small error in the angle can translate to a much larger error in position when traveling long distances.

Students analyze international oil consumption and production data. They make several graphs to organize the data and draw conclusions about the overall use of oil in the world.

In this task using a number line, students must partition the interval between 0 and 1 into eighths.

This task assesses a student's ability to use the addition rule to compute a probability and to interpret a probability in context.

Students are exptected to identify the slope of the line with the unit rate in this real world problem.

A Power Point presentation offering effective communication starters. As well, a rubric to assess group work is included.

This website has various video challenges with accompanying PDF's for student use . Students are able to post their own videos of how they solved the challenge, and take a look at how others solved it as well.

n this task, students are able to conjecture about the differences in the two groups from a strictly visual perspective and then support their comparisons with appropriate measures of center and variability. This will reinforce that much can be gleaned simply from visual comparison of appropraite graphs, particularly those of similar scale. Students are also encouraged to consider how certain measurements and observation values from one group compare in the context of the other group.

The purpose of this task is to help students understand the connection between counting and cardinality. Thus, oral counting and recording the number in digit form are the most important aspects of this activity. However, teachers can extend this by making a bar graph about how many students are wearing the color each day.

The primary purpose of this problem is to rewrite simple rational expressions in different forms to exhibit different aspects of the expression, in the context of a relevant real-world context (the fuel efficiency of of a car). Indeed, the given form of the combined fuel economy computation is useful for direct calculation, but if asked for an approximation, is not particularly helpful.

This task gives students an opportunity to work with exponential functions in a real world context involving continuously compounded interest. They will study how the base of the exponential function impacts its growth rate and use logarithms to solve exponential equations.
