On January 6th and 7th students will take unit 4 test on the make of matter. The building block of matter is an atom and an atom is the smallest part of an element. Two or more elements chemically combined are called compounds. When element and compounds (or a variety of theses) are physically combined they form mixtures. Unit 4 test is on elements, compounds and mixtures.
November 30 will be an odd day.
We are studying phases, or states of matter. There are four phases of matter (solid, liquid, gas and plasma). This is a physical change that requires heat energy.
December 1 and 2 students will have Unit 3 Test on chemical and physical properties, acids and bases, and phases of matter. Students have a student guide for unit 2 and unit 3 they should study.
Test 3 is postponed unit December 3 and 4th. More review is/was needed.
