In this activity, students will explore two given websites to gather information on Bone Mineral Density and how it is measured. They will also learn about X-rays in general, how they work and their different uses, along with other imaging modalities. They will answer guiding questions as they explore the websites and take a short quiz after to test the knowledge they gained while reading the articles.

This lesson focuses on the use of elevation maps with a focus on Michigan's Muskegon River Watershed. Students are introduced to an elevation profile tool and expected to produce a profile of two other Michigan rivers and examine their watersheds. Success with this lesson will include drawing a simplified profile of one of the rivers as well as labeling two watershed boundaries and the river.

As a society, we use land in many different ways. The way we use land has a tremendous impact on how water flows over and through land as it makes it way to streams, rivers, and the Great Lakes. When rainwater falls on land, it gradually makes its way downhill. In developed areas, including both farms and urban areas, there is much less vegetation to slow the water down. As a result, the water moves quickly over the surface of the ground, picking up dirt and other materials and carrying it along with the flow of water. This process is known as "erosion." The suspended material, called "sediment," is carried through the watershed to the streams, rivers, and lakes. Success with this lesson will happen when students are able to explore the land use around sample Michigan sites, and use that information to analyze which sites have the highest average sediment levels and which have the lowest.

Rivers are incredibly important to our society and our environment, but we haven't always treated our rivers as well as we should. By using pictures taken from satellites orbiting the earth, we can examine rivers all over Michigan and try to identify those rivers that appear to have higher water quality and those that appear to have lower quality. Based on the illustrations provided, students will be able to make a number of observations about the quality of Michigan's rivers. Two specific rivers, the Rouge River and Escanaba River, will be observed and conclusions made about water quality and types of land use surrounding it. Lesson success will include having students log into ArcGIS Online to explore the river nearest their home so they can produce a table of observations and a 3-5 sentence paragraph to summarize their findings.

As rain falls all over Michigan, the water gathers in small local watersheds, which feed into larger regional watersheds, which ultimately feed into the Great Lakes. Water that falls on the land in Michigan eventually flows into one of the Great Lakes because the elevation of the Great Lakes is generally lower than the elevation of the land in Michigan. Students will be able to use elevation maps to study water flow from watersheds emptying into the Great Lakes. Success with this lesson will happen when students can investigate the Great Lakes water flow and produce a simple diagram that illustrates this flow pattern.

Basic principles of planet atmospheres and interiors applied to the study of extrasolar planets (exoplanets). Focus on fundamental physical processes related to observable exoplanet properties. Quantitative overview of detection techniques. Introduction to the feasibility of the search for Earth-like planets, biosignatures and habitable conditions on exoplanets.

Based on what they have already learned about friction, students formulate hypotheses concerning the effects of weight and contact area on the amount of friction between two surfaces. In the Associated Activities (Does Weight Matter? and Does Area Matter?), students design and conduct simple experiments to test their hypotheses, using procedures similar to those used in the previous lesson (Discovering Friction). An analysis of their data will reveal the importance of weight to normal friction (the friction that occurs as a result of surface roughness) and the importance of surface area to the friction that occurs between smooth surfaces due to molecular attraction. Based on their data, students will also be able to calculate coefficients of friction for the materials tested, and compare these to published values for various materials.

All of us have felt sick at some point in our lives. …
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 simulation helps students feel what happens to the sound when you adjust the loudness and pitch. It asks students “What do you feel happen when you touch the speaker?” and “What do you hear happen to the sound?” This is used in Lesson 3 of Unit 8.2 of the OpenSciEd curriculum.

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.

This activity is an interactive “out-of-the-seat” demo that allows the students to become involved in learning about fibre optic cables by imitating the way that one basically functions. While enjoying the physicality of the demo the children will pick up basic details of light, reflection, optical properties, and applications to technology. Additionally, the activity will go into details of how fibre optics are used in astronomy technology and how it is used to improve our understanding of the universe. An emphasis should be placed on asking direct questions to the children about how these concepts can influence technology, astronomy, and our world to reinforce the concepts that they are learning about.
