This this task about mixing paint requires students to graph ratios on a coordinate plane. It is a standard language in ratio problem.

Students learn more about how muscles work and how biomedical engineers can help keep the muscular system healthy. Following the engineering design process, they create their own biomedical device to aid in the recovery of a strained bicep. They discover the importance of rest to muscle recovery and that muscles (just like engineers!) work together to achieve a common goal.

This activity is designed to determine the appropriate instructional level for a student in a one-on-one interaction with the teacher.

In this assessment in a one-to-one setting, a student is shown the numbers from 1Đ10, one number at a time, in random order. The teacher asks, Ňwhat number is this?"

This assessment task can be used with a single student or a small group of students. Each student needs his or her own set of numeral cards.

This assessment may be used in a small group or whole group setting, give each student a piece of paper. Students who have trouble writing certain numbers can then get targeted practice.

Students use spreadsheet tables and charts to explore the Gutenberg-Richter relationship between an earthquakes magnitude and recurrence interval.

In this study funded by the Energy Foundation, performed by Lotus Engineering, and released by the International Council on Clean Transportation (ICCT), the potential mass reduction of a 2009 Toyota Venza is evaluated. Through advanced methodologies, Lotus replaces components with various high strength materials and reduces the quantity of components through integration. It's concluded in low development 21% mass may be reduced while cost is kept to 98% and in high development 38% mass may be reduced while cost is kept to 103%.

In this activity, students will explore how the Law of Conservation of Energy (the First Law of Thermodynamics) applies to atoms, as well as the implications of heating or cooling a system. This activity focuses on potential energy and kinetic energy as well as energy conservation. The goal is to apply what is learned to both our human scale world and the world of atoms and molecules.

We use motion detectors and a bowling ball to find relationships velocity, mass, and energy.

A Software Carpentry lesson to learn how to use Make Make is a tool which can run commands to read files, process these files in some way, and write out the processed files. For example, in software development, Make is used to compile source code into executable programs or libraries, but Make can also be used to: run analysis scripts on raw data files to get data files that summarize the raw data; run visualization scripts on data files to produce plots; and to parse and combine text files and plots to create papers. Make is called a build tool - it builds data files, plots, papers, programs or libraries. It can also update existing files if desired. Make tracks the dependencies between the files it creates and the files used to create these. If one of the original files (e.g. a data file) is changed, then Make knows to recreate, or update, the files that depend upon this file (e.g. a plot). There are now many build tools available, all of which are based on the same concepts as Make.

In this real world problem students solve questions based on the relationship between production costs and price.

Students use their senses to describe what the weather is doing and predict what it might do next. After gaining a basic understanding of weather patterns, students act as state park engineers and design/build "backyard weather stations" to gather data to make actual weather forecasts.

In this inquiry activity, students generate investigable questions to explore the link between hygiene/cleanliness and bacteria growth/population. The students will present their conclusions, and video clips containing additional information will be discussed.

This task provides a real world context for interpreting and solving exponential equations. There are two solutions provided for part (a). The first solution demonstrates how to deduce the conclusion by thinking in terms of the functions and their rates of change. The second approach illustrates a rigorous algebraic demonstration that the two populations can never be equal.

Spreadsheets Across the Curriculum module. Students tabulate and graph data on bacteria density vs. time for a culture. Data start with innoculation and progress through the peak and decline.

This series of word problems requires students to apply the concepts of factors and common factors in a context.
