Y 9 Chemistry
Homework 8 April • Select short report on a chemical problem issue • Select 3 words and make a glossary of terms • Write 3 Comprehension questions • Gmail : Drhillteach@gmail.com
Example
Review of rules • Ionic make ions of Nobel gases – ionic crystal • Covalent share by overlap – shaped molecule, macro molecule
Mass conservation – R&V • Mass conserved because atoms don’t disappear or are appear • Validity – fair and correct procedure that measures what you think • Reliability – quality of answer, how repeatable • Need to know dependant and independent.
