All of us have felt sick at some point in our lives. Many times, we find ourselves asking, "What is the quickest way that I can start to feel better?" During this two-lesson unit, students study that question and determine which form of medicine delivery (pill, liquid, injection/shot) offers the fastest relief. This challenge question serves as a real-world context for learning all about flow rates. Students study how long various prescription methods take to introduce chemicals into our blood streams, as well as use flow rate to determine how increasing a person's heart rate can theoretically make medicines work more quickly. Students are introduced to engineering devices that simulate what occurs during the distribution of antibiotic cells in the body.
This project will be focused on designing, constructing and evaluating different containers to determine the optimal design for heat retention. After students have constructed their designs and collected and shared data, students will evaluate the class data to create an optimal design for our culminating event: warming ooey, gooey chocolate chip cookies to perfection! Through this activity, students will learn about energy transfer, engineering design process, data collection, graphing, rate of change, optimization, surface area and proportions. The students will test the effectiveness of their design using Vernier Probes to gather quantitative data and graphing the rate of temperature change. They will then create a poster presentation to share their data to the class. Students will use their mathematical skills to quantitatively analyze the strength and weaknesses of their designs while enjoying some delicious, toasty, warm cookies.
Working individually or in groups, students explore the concept of stress (compression) through physical experience and math. They discover why it hurts more to poke themselves with mechanical pencil lead than with an eraser. Then they prove why this is so by using the basic equation for stress and applying the concepts to real engineering problems.
The last video in our anatomy and physiology lecture series focuses on the female reproductive system. This video introduces us to the female reproductive system. We take a quick look at the components of the female reproductive system and the functions of the female reproductive system.
Lesson 1 in our Female Reproductive System series. This is part of our Anatomy and Physiology lecture series.

Students develop and solidify their understanding of the concept of "perimeter" as they engage in a portion of the civil engineering task of land surveying. Specifically, they measure and calculate the perimeter of a fenced in area of "farmland," and see that this length is equivalent to the minimum required length of a fence to enclose it. Doing this for variously shaped areas confirms that the perimeter is the minimal length of fence required to enclose those shapes. Then students use the technology of a LEGO MINDSTORMS(TM) NXT robot to automate this task. After measuring the perimeter (and thus required fence length) of the "farmland," students see the NXT robot travel around this length, just as a surveyor might travel around an area during the course of surveying land or measuring for fence materials. While practicing their problem solving and measurement skills, students learn and reinforce their scientific and geometric vocabulary.
This paper model of the Fermi Gamma-ray Space Telescope includes three pages of parts that can be cut out and assembled using common household items. It also provides a short description of the scientific instruments on board Fermi, as well as links to other resources about its instruments.
This is a series of five activities about geology on the moon. Learners will explore lunar stratigraphy (caused by lava flows), impact craters, the moon's history, spacecraft design in which students build models of the LRO out of edible or non-edible materials, and the future of lunar exploration. This guide includes the activities from the original Field Trip to the Moon guide plus activities relating to these two moon missions - Lunar Reconnaissance Orbiter and the Lunar Crater Observation and Sensing Satellite.
This site will give you a quick run down of how to use Figjam and then it provides 20 great ideas for using Figjam in the classroom - including the templates to get started!
There is even a video to keep it very easy!

This lesson describes the major components and functions of the immune system and the role of engineers in keeping the body healthy (e.g., vaccinations and antibiotics, among other things). This lesson also discusses how an astronaut's immune system is suppressed during spaceflight due to stress and other environmental factors.
Students study an ancient bronze statue, analyze its pose, and discover how conservators remove and prevent corrosion. They learn that the bronze used to make this sculpture is an alloy of copper and tin with small amounts of antimony, lead, iron, silver, nickel, and cobalt. They use the periodic table to research the chemical formulas of compounds used to make bronze. After learning about oxidation-reduction reactions that occurred in the statue, students speculate about the conservation techniques needed to conserve the bronze sculpture.

They use the periodic table to research the chemical formulas of compounds used to make bronze. Students compare conservation techniques in two ancient bronze objects.
Today we’re going to look at how our computers read and interpret computer files. We’ll talk about how some popular file formats like txt, wave, and bitmap are encoded and decoded giving us pretty pictures and lifelike recordings from just strings of 1’s and 0’s, and we’ll discuss how our computers are able to keep all this data organized and readily accessible to users. You’ll notice in this episode that we’re starting to talk more about computer users, not programmers, foreshadowing where the series will be going in a few episodes.
Filtering is the process of removing or separating the unwanted part of a mixture. In signal processing, filtering is specifically used to remove or extract part of a signal, and this can be accomplished using an analog circuit or a digital device (such as a computer). In this lesson, students learn the impact filtering can have on different types of signals, the concepts of frequency and spectrum, and the connections these topics have to real-world signals such as musical signals. Students also learn the roles that these concepts play in designing different types of filters. The lesson content prepares students for the associated activity in which they use an online demo and a variety of filters to identify the message in a distress signal heavily corrupted by noise.
We plan to facilitate several engineering lessons that requires students to design, build ROV controllers, calculate weight, underwater thrust and buoyancy.
In this activity students will learn the basic concept of Global Positioning Systems (GPS) using triangulation and measurement on a small scale in the classroom. Students discover how GPS and navigation integrate mathematic and scientific concepts to create a standard for locating people and objects. This activity helps students understand both the need for and methods of navigation.
