See how the equation form of Ohm's law relates to a simple circuit. Adjust the voltage and resistance, and see the current change according to Ohm's law. The sizes of the symbols in the equation change to match the circuit diagram.

This lesson is designed for upper elementary and middle school students where they will identify peripheral input, output and storage devices used within the computer information processing system.  Students will take pictures and obtain copy free right pictures of these devices and organize them into an Adobe Creative Cloud Express presentation, formerly known as Adobe Spark.  Thumbnail credit:  “Computer with mouse and keyboard.png” by Hacker19374.  This file is licensed under the Creative Commons Attribution-Share Alike 4.0 International license.

You are part of a team of engineers who have been given the challenge to design a bridge out of popsicle sticks and glue. Bridges must be able to hold at least 20 pounds. The bridge must span at least 14 inches in length. But, it must be longer than 14 inches because when it has been constructed, it will be placed between two desks so it is at least one foot above the floor for a weight-bearing test. In addition to meeting the structural and weight bearing requirements, the bridge will be judged on its aesthetics as well, so be creative! And, you are encouraged to use the fewest number of popsicles possible to achieve your goal.Budget: $20,000Materials:Popsicle Sticks: $200 eachGlue Sticks: $300 eachString: $50/inchYou will present your results to the class using Keynote and iMovie.

This lesson is for students who are very familiar with CSfirst or Scratch, and is intended to deepen and assess their familiarity with the blockly code language used in both. First the class discusses what "reverse engineering" is and why is is beneficial to them. Then, they will work in groups to recreate an example scene playing on the main screen, one sprite at a time. At the end, the students will compare their work to the code from the example project and discuss any differences that make the code work better, worse, or more efficiently. They will share the link to their group project to turn it in.
