Bruce Palmquist Central Washington University 2012 WA AAPT Workshop

 What’s PhET  Work on E Field relationship activityactivity  Briefly review V, E, and r relationships activityactivity  How to create your own investigative assignment  Briefly review H atom activityactivity  Start planning your own investigation  (If time: share your idea)  Today’s presentation at http://goo.gl/GmEHh

 Two main goals of PhET simulations ◦ Increase student interest ◦ Improve student learning  The animated, interactive and game-like environments help students learn through exploration  Can be used as an interactive demonstration, homework, confirmation lab activity, hypothesis testing activity

 Open the Charges and Fields SimSim  Do the initial exploration (first 2 bullet points)  Complete hypothesis 1 and 3 (note If, then, because format)  Gather the data for hypothesis 1 and 3

1. Point charge  -2  -1.8  -2 2. Line of charges  -1.14  -1  -1.2 3. Beside a “narrow” dipole  -3  -2.9 4. Above a “narrow” dipole  -3  -2.9

 Similar activity for electric potential using the same simactivitysim  Key to developing an effective activity: use student or peer feedbackpeer

 First look to see what has already been developed at the bottom of the pagepage  Play with the activity and determine which parameters can be manipulated  Of those, determine which have a measurable response  If the sim is complex, have a short exploration task before asking students to hypothesize  Make sure students develop a hypothesis before doing the experiment  Students should formulate their own conclusion and relate it back to the hypothesis

 Developing a model of the H atomatom  Students make a prediction, run a simple “experiment”, and compare  Then, they develop a model of the H atom and compare to 6 standard models  Used to teach the science process in a non-science honors class

 Find a PhET simulation that fits in your curriculum  Play with the activity and determine which parameters can be manipulated  Determine which have a measurable response  Develop a short exploration, if needed  Insert the hypothesis-making step in the appropriate place  Optional: Submit your wonderful new activity to PhET and get a gold starstar
