Year 9 chemistry

Today‘s topics Overview of the school year and testing General lab rules Rules for practical work Hazard symbols Getting to know some lab equipment

School year and testing This year‘s topics Substances, mixtures, separation processes Chemical reactions Atoms, molecules and ions The periodic table Ionic compounds, metals, covalent compounds Units and calculations Testing One oral grade (UB) per term One Term Test per term One graded lab report in term 2 or 3

General lab rules Lab rules Safety features No drinking or eating inside the lab Closed shoes Being down in the lab on time Safety features Emergency buttons Faucets and eye shower Fire extinguishers and fire alarm

Let‘s get started!

Rules for practical work On your own: Work through worksheet 1 At your table: Compare and discuss your drawings and explanations Let’s present some of your work!

Hazard symbols 1. Substances and reactions Complete the hazard symbol worksheet with your neighbor Let’s compare your results! Put the following lines into your workbooks: 1. Substances and reactions 1.1 Lab safety -> Worksheet 1 Hazard symbols Stick the correct combinations into your workbook Small homework: Looks for substances at home that carry hazard symbols!

Getting to know some lab equipment Work through the back of worksheet 1 with the rest of your table Let’s present your results!
