Students continued to work with the marshmallows to model acid and base dissociation. What is the molecule at the bottom left called? What is its charge? First right answer = one bonus point.
Students began work on an activity that develops the idea that acids provide H+ ions and bases provide OH- (hydroxide) ions. Which one below is the acid? the base? What is dissociation? First to answer gets a bonus point.
Return of graded work (including pH activity and motion test). How did your results compare to the chart below? If students want to retake the test they must 1) make test corrections 2) complete the review problems on the Google … Continue reading
Assessment on Motion. Exam covered distance-time graphs, velocity-time graphs, linear motion, and simple projectile motion. Liked this for acids and bases! What word is misspelled? First to answer gets a bonus point! Will be updating entries for 2/16 and 2/21 … Continue reading
Students wrapped up pH lab and handed it in. A shared Google doc has sample problems and graphs (like the one below) to help prepare for tomorrow’s assessment on motion.
Students used indicator paper to find the pH of common substances. The paper was sensitive to pH from 0.0 to 13.0 in o.5 increments.
Intro to Ch 5 activity where students listed common household items as either acids or bases. The list was reconsidered when the characteristics of acids and bases were given. Click on chart below for a larger image.
Return of graded work. Student who wish to clean up the Projectile Motion lab should resubmit by 2-24-12. Two new Study Island modules were assigned and worked on.
