MidTerm Quiz

1. Prepare an index card for each activity; these cards must have lab activities, computer simulation and science talk activty
2. On each card, please summarize the data that you collected and a one sentence statement of the scientific meaning of the data an index card; you may want to crate several duplicates of each card
3. On a different index card, copy the statements from question 1 of the mid-term exam
4. Create a matrix/grid of the index card with test prompts on side and data from each activity next to the appropriate statement (see below).

TEST PROMPT DATA from activity DATA from activity DATA from activity
A molecule is simply two or more…. Electrolysis Lab; we learned that the decomposition of water occurred when current were placed in the tubes; Gas bubbles formed in the tube were likely from hydrogen gas  released because the gas popped when a flame was applied; colors changed for the pH indicator; the other tube was supposed to relase a gas (likely oxygen since water is composed of hydrogen and oxygen).     
One puzzle had to do with spectral readings of the wavelengths of hydrogen… Spectral Tubes and Science Talks: In our science talk, we discussed how there was no medium ground for energy levels, like a ladder; only one wavelength or another; this expalained the gaps in the spectral tubes…. Light Tour: We also observed these color gaps during the light tour of Milledgeville…. PHET Simulation: The simulation in Dr. Richards' lab we began to see when the e;ectron jumped; we brought this up in the Science Talk…
