Some of the most vivid pigments in medieval manuscripts were manufactured through alchemy, an experimental practice that predates modern chemistry. Today, chemistry deepens our knowledge about paint colors, their identification, and potential continued transformations.

 Alcoholic Fermentation in Yeast – A Bioengineering Design Challenge Grade Level: 10thSubject: ALSAnimalsDuration: 90 minutesDOK Level: 3SAMR Level: Substitution Indiana Standard: ALSA-2.17 Describe cellular respiration. Recognize that animals perform only respiration, while plants perform both photosynthesis and respiration. Also, describe the transformation of energy during respiration, and the role of ATP produced in respiration for other metabolic processesObjective: Students will be able to explain the process of cellular respiration and design an experiment .Essential Question: What is the optimum sucrose concentration and temperature to maximize rapid CO2 production?Procedure: Handout the student lab sheet.Have the students answer the questions in part 1Have them draw the steps in part to in their research notebookHave the students complete the lab part 2Have the students record the results in their research notebookHave the students design and complete lab part 3Product or Assessment: Students will be assessed on their results in their research notebook. Credit: Cellular Respiration lab http://serendip.brynmawr.edu/sci_edu/waldron/Teacher Preparation Notes 

This activity helps students to understand both alcoholic fermentation and the engineering design process. In the first two parts of this activity, students learn about alcoholic fermentation and test for alcoholic fermentation by assessing CO2 production by live yeast cells in sugar water vs. two controls. The third part of this activity presents the bioengineering design challenge where students work to find the optimum sucrose concentration and temperature to maximize rapid CO2 production. Structured questions guide the students through the basic engineering steps. This activity helps students meet the Next Generation Science Standards.

Alcohol or ethanol fermentation, including yeast and its role in bread and wine production.

Aldosterone is a steroid hormone which is secreted from the zona glomerulosa of the adrenal gland. It has a mineralocorticoid activity and is the most important regulator of plasma potassium. When plasma potassium increases, increased stimulation of aldosterone occurs directly and also as a result of the Renin-Angiotensin-Aldosterone System (RAAS). Aldosterone is also the most important regulator of sodium excretion.

In Florida's humid climate, strawberry growers are in a constant battle with two kinds of fruit rot. Using a decision support system, they can save money by spraying fields only when the plant diseases are a threat.

In this Interactive Lecture Demonstration, students will predict the main issues that might be included in short French language videos treating topics such as endangered species, organic farming, the effect of aerosols on the environment, pollution and sustainable development. They will then view short videos on the topics and reflect on how their prior assumptions meshed with reality.

OER Fundamentals are invited to remix this course planning template to design and share their OER project plans, course information and syllabus, and reflection.

This site contains correspondence, scientific notebooks, journals, blueprints, articles, and photographs documenting the invention of the telephone, his involvement in the first telephone company, family life, interest in the education of the deaf, and aeronautical and other scientific research. Included is his notebook containing the entry from March 10, 1876, describing the first successful experiment with the telephone, during which he spoke the famous words, Mr. Watson, Come here, I want to see you.

Manuscripts, images, and historic newspapers document the life and accomplishments of Alexander Hamilton. This set also includes a Teacher's Guide with historical context and teaching suggestions.
