Today in class students got their first crack at taking the periodic table quiz. Everyone of the 12 students that attempted the quiz earned over a 100% (with the extra credit elements). What a great start!!!
After the quiz we discussed what information could be determined by looking at an element on the periodic table. By the end of the period, students had to know the atomic number, atomic mass and the number of protons, neutrons and electrons for any element on the periodic table. Students practiced this on page 3-14. We then discussed the existance of isotopes and watched a http://www.brainpop.com/ video on the topic. We ended the class by completing worksheet 3-15.
No homework was assigned.
Remember that the test is a week from tomorrow, on Thursday, December 10th.
