The problem presents a context where a quadratic function arises. Careful analysis, including graphing, of the function is closely related to the context. The student will gain valuable experience applying the quadratic formula and the exercise also gives a possible implementation of completing the square.

In Assisted Melody, users are given a digital keyboard where they can select notes and then using the Harmonize button, your notes will be combined with the works of great composers like Mozart, Back, and Beethoven. Users can also change the instrument and tempo to hear different styles of music.

The goal of this lesson is to introduce students who are interested in human biology and biochemistry to the subtleties of energy metabolism (typically not presented in standard biology and biochemistry textbooks) through the lens of ATP as the primary energy currency of the cell. Avoiding the details of the major pathways of energy production (such as glycolysis, the citric acid cycle, and oxidative phosphorylation), this lesson is focused exclusively on ATP, which is truly the fuel of life. Starting with the discovery and history of ATP, this lesson will walk the students through 8 segments (outlined below) interspersed by 7 in-class challenge questions and activities, to the final step of ATP production by the ATP synthase, an amazing molecular machine. A basic understanding of the components and subcellular organization (e.g. organelles, membranes, etc.) and chemical foundation (e.g. biomolecules, chemical equilibrium, biochemical energetics, etc.) of a eukaryotic cell is a desired prerequisite, but it is not a must. Through interactive in-class activities, this lesson is designed to spark the students’ interest in biochemistry and human biology as a whole, but could serve as an introductory lesson to teaching advanced concepts of metabolism and bioenergetics in high school depending on the local science curriculum. No supplies or materials are needed.

Learn about common problems in audio production, how to solve them and what you can do to capture quality audio.

Students learn how to conquer external audio recorders and best practices for recording and syncing audio. This resource includes a video and teaching resources.

Students learn how sound can make or break their videos, why understanding the power of audio in video production is important, and an overview of different types of mics.

This is a lesson is meant to guide educators through the autobiogrpahy Adobe Express project. Students will create an autobiography video of their life. They will document their life with picutres and present using Adobe Express video. 

Stephanie Howell posted this a few weeks ago and I thought, "What a great way to connect with students at the beginning of the year and then throughout the year!" Using her template, a Google add-on called Autocrat, and her video tutorial, you can set up a Google Form/Sheet to automatically send students a digital birthday card throughout the year. It takes about 20 minutes to set up but then it runs automatically throughout the year!

Students will explore the vice of ambition in a constitutional republic and civil society in this lesson on civic virtue.  Students will examine the difference between self-serving ambition and noble ambition, and then explore the character and career of Aaron Burr. Burr engaged in various machinations to establish an empire in the West and was put on trial for treason.  Students will analyze a historical narrative, discussion guide, and various activities to explore the effect of self-serving ambition in a constitutional republic and on civil society.

Review abbreviations of words used in recipes, acceptable substitutions of foods in recipes, standard equivalents of measurements and correct terminology of cooking terms through the use of written assignments using handouts and cookbooks as resources.

The students will apply and demonstrate in a practical lab test what they have learned from their previous classes by reading and preparing an acceptable food product together as a unit making Chocolate Drop Cookies. They will need to know measuring, cooking terms, abbreviations, equivalents, substitutions, altering a recipe, and location of equipment in the unit.
