Students set up various demonstrations make observations and draw conclusions from the demonstrations about simple machines.

Design and Create a whirlgig. The last day to create the whirligig is October 14th.
Today, Students were introduced to technology education class, or as I often refer to it: Engineering. We quickly went over fire drill procedures and lock down procedures. Students were then challenged to build a pyramid that is at least 4 cups tall using only string, rubber bands, and coffee stirrers. They were not able to touch the cups with any part of their body. Through this activity students realized the importance of cooperation and teamwork. They also learned the value of varying perspectives. They learned that we learn things from failure, since very few students if any completed this challenge successfully the first time, and that problem solving can be fun.
HW: Bring in a 2 pocket folder for next class. Students are designing and creating their own CO2 car, which they will race at the end of the trimester.
Students created their own customized CO2 car wheels that will be printed and put on their own CO2 car.
Today, students were assigned a take home project where they have to create a chain reaction of events. The project description and rubric are located below. Students can choose to work by themselves or with one other person. If you are working by yourself you need to use at least 3 different simple machines and the chain reaction has to have at least 5 separate steps. If you are working with a partner, the pair needs to use at least 5 different simple machines and the chain reaction has to have at least 8 separate steps. Each project should be submitted as a video (on flash drive or emailed to Mrs. LaRosa) and a labeled picture of the Rube Goldberg with written description of simple machines used and steps. Students set up a series of demonstrations in class to see how each different simple machine works. Then each student records what they observe and answers some questions about what they learned.
Students were assigned a write up to do on their whirligig. The write up should include a written procedure, safety rules followed, a self evaluation, and a picture. A complete list of what is needed an points associated with each part is located in document below. The day has come! Today we started creating our whirligigs! Students began to trace his/her templates on pieces of wood, drill holes through the body of the whirligig where the wings will attach, and cut out the outline of the whirligig. The last class day to work on whirligigs will be Friday 4/29.
