Experimental techniques
Today students used the timers, photogates, cars, weights and ramps to determine and modify the variables in a self designed experiment. Students varied the slope of their ramps, added weights to their cars, varied the distance between photogates, and practiced different release techniques. The class then established degree of slope as their independent variable, and made all other variables constant.

Time Flies Like an Arrow
...and fruit flies like a banana (OK, it's an old joke, but I'm a geezer).
Today we learned to use the CPO digital timers and photo gates. Students learned how to operate a single photogate and tandem photogates. The students discovered that an object must be large enough to completely sever the photobeam in order to start or stop the interval clock.

Physical Science Blog
Duncan High School is re-vamping its physical science classes in order to incorporate more hands-on activities and experiments. As the facilitator, I have decided to try blogging certain aspects of the class: activites, self/team evaluations, still pictures, and videos of class work.
All students must have signed internet agreement forms on file with Duncan High School.
All students must have signed media release forms on file also.
Students will be referred to by initials or team designations. Comments should be kept to the topic, and not be personal. If a team member is not performing at an acceptable level, see me after class and we will resolve the problem.
Questions to be answered on the self/team evaluation forms include:
1. What is one interesting observation you made during the investigation, or one thing that surprised you?
2. What is one thing you learned?
3. Why is the information you learned important to your studies, your life, or to others?
4. What question do you have after completing this investigation? What would you like to know about?
5. How would you explain this investigation to someone else through writing, a conversation, or with a drawing?
