Daily Science: Students where given simple chemical equations to balance.
We spent the rest of the hour working on balancing chemical equations of a handout. Students worked on their own, and several equations were also presented on the board. Students should complete handout for homework. Students are to show their work (attached on loose leaf) Due Friday. Test on Essential Elements is scheduled for this Thursday. Students will be able to use their essential elements chart during the test. The test will cover the following: Chapter 3 lesson 1: Students should know The difference between an element and a compound and be able to include and example of each. The important groups of organic compounds, what elements they are made off and where they are found in a cell. Parts of the atom (protons, neutrons electrons; where they are found and their charges). Basic use of the periodic table. What information can we get from the periodic table for each element? ( What is the atomic number and what is it equal to? what is the atomic mass, and what is it equal to? How can we calculate the number of neutrons?) Balancing of simple chemical equations. The students should also know the % of the most important elements. E.g. which one is the most abundant element, second most abundant, third etc (see the pie chart we drew in class).
