This is the second module in our training series that will provide participants with an introduction to OER evaluation tools. We have designed these modules to first spark the learner's interest in the topics covered and then dig deeper into the content through presentations, storytelling, and demonstrations of the tools. We will offer opportunities for learners to practice exploring the resources and tools, and reflect on how they might use them in their work.

This lesson unit is intended to help teachers assess how well students are able to use geometric properties to solve problems. In particular, it will help you identify and help students who have difficulty: decomposing complex shapes into simpler ones in order to solve a problem; bringing together several geometric concepts to solve a problem; and finding the relationship between radii of inscribed and circumscribed circles of right triangles.

This course introduces fundamentals of radon physics, geology, radiation biology; provides hands on experience of measurement of radon in MIT environments, and discusses current radon research in the fields of geology, environment, building and construction, medicine and health physics.
The course is offered during the Independent Activities Period (IAP), which is a special 4-week term at MIT that runs from the first week of January until the end of the month.

This undergraduate level course presents a basic study in geology. It introduces major minerals and rock types, rock-forming processes, and time scales; temperatures, pressures, compositions, structure of the Earth, and measurement techniques; geologic structures and relationships observable in the field; sediment movement and landform development by moving water, wind, and ice; crustal processes and planetary evolution in terms of global plate tectonics with an emphasis on ductile and brittle processes.

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).

Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple's offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the "couples" in the class. In particular, they look to see if there are cases where parents and offspring share the exact same genotype and/or phenotype, and consider how the results would differ if they repeated the simulation using more than four traits.

Students will examine ways declining bee population can impact day to day life, by considering how the cost of honey and pollination has been affected society Students will create real-world problems that relate to statistics on the declining bee population.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"A new method for identifying post-translational modifications in proteins promises to cut biomedical researchers’ workload in half. Enabling multiple affinity enrichment procedures to be run in parallel, the one-pot method yields the same search results as traditional methods in less time and from less tissue. As proteomics researchers know well, identifying post-translational modifications in biological samples can be tedious. Enriching samples with target modifications, such as the attachment of acetyl , succinyl or methyl groups to amino acid residues, and matching experimental data with catalogued results involves numerous steps. And the work load is only getting bigger. With exploding interest in how multiple modifications are linked across the vast proteome , the amount of time and the amount of sample required for exploration are skyrocketing in proportion. But with the new one-pot enrichment method, that could soon change..."

Booleans are the fourth and final data type that students will learn about in this course. In this stage, students will learn about Boolean (true/false) values, and explore how they can be used to evaluate logical questions.

Understanding Biodiversity presents an overview of biodiversity, its importance and relevance to humans, all living things, and the Earth. It includes species pages and a template to engage and involve students in real-life data collection.

The various infographics show one application of marketing and communications on the topic of agriculture. Here, the United States Department of Agriculture compiled data and designed it graphically to share about agriculture, its impacts on communities, and consumer education.

The Process of Science Companion is composed of the following four books: Science Communication; Scientific Group Collaboration; Data Analysis, Statistics, and Experimental Design; Tools and Techniques. These resources provide support for students doing independent research.

Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it!

(This case study was added to OER Commons as one of a batch of over 700. It has relevant information which may include medical imagery, lab results, and history where relevant. A link to the final diagnosis can be found at the end of the case study for review. The first paragraph of the case study -- typically, but not always the clinical presentation -- is provided below.)

A man in his forties with a history of basal cell carcinoma of the nose and a benign neoplasm of the jaw, status post resection with mandibular reconstruction, presented for routine follow-up. On chest x-ray workup, he was found to have numerous bilateral pulmonary nodules that were highly suspicious for a metastatic disease. A follow-up CT scan of the chest with contrast showed eight small round pulmonary nodules measuring few millimeters in size and a larger left lower lobe pulmonary mass measuring 3.0 x 3.1 cm in size. There was no evidence of hilar or mediastinal lymphadenopathy and no pleural nodularity or effusion on imaging.

William Holman Hunt, Claudio and Isabella, 1850, oil on mahogany, 758 x 426 x 10 mm (Tate Britain) From William Shakespeare's Measure for Measure, Act III, scene 1 (a room in a prison): ISABELLA What says my brother? CLAUDIO Death is a fearful thing. ISABELLA And shamed life a hateful. CLAUDIO Ay, but to die, and go we know not where; To lie in cold obstruction and to rot; This sensible warm motion to become A kneaded clod; and the delighted spirit To bathe in fiery floods, or to reside In thrilling region of thick-ribbed ice; To be imprison'd in the viewless winds, And blown with restless violence round about The pendent world; or to be worse than worst Of those that lawless and incertain thought Imagine howling: 'tis too horrible! The weariest and most loathed worldly life That age, ache, penury and imprisonment Can lay on nature is a paradise To what we fear of death. ISABELLA Alas, alas!

This activity was developed to give participants an understanding of Earth's water cycle by completing a WebQuest and building a model of the water cycle.

In this lesson, students will learn about the water cycle and how energy from the sun and the force of gravity drive this cycle.

This lesson gives students a strategy for evaluating sources.  This lesson is part of a media unit curated at our Digital Citizenship website, "Who Am I Online?".

Students learn about electrical connections, how they work and their pervasiveness in our world. They consider the usefulness of wireless electrical connections for connecting electrical devices. Morse code is introduced as a communication method that takes advantage of on/off states to transmit messages by electrical bursts sent via wires, light or sound. They learn the Morse code rules and translate a few phrases into Morse code. Specifically, they learn about a wireless connection type known as Bluetooth that can be used to control LEGO robots remotely from Android devices, which leads into the associated activity.

"Abnormal wearing of the hip joint, or femoroacetabular impingement, and dysplasia represent the two most common causes of secondary osteoarthritis of the hip joint. These pathologies are known to produce distinctive chondral flaps visible during hip arthroscopy. But the destructive mechanics behind each diagnosis differ significantly. That makes treatment planning especially difficult for patients who show signs of both impingement and dysplasia. To provide some clarity, researchers examined 95 patients demonstrating acetabular chondral flaps during arthroscopy, with the goal of correlating those findings with radiographic data. The patterns that emerged could help surgeons deliver the best possible care for patients with mixed hip pathologies. Patients exhibited one of two types of chondral flaps upon examination: “inside-out” or “outside-in”..."
