How do we work in this laboratory?

1. Start and End of class: Lining up, put our bags away, find a seat, do fun experiment, when bell rings wait till your teacher releases you.
2. Equipment tray: equipment list and what they are used for.                                                                                                                                                                                                      1.Test tube - This is used  for experiments using liquids.They have a bung that can be placed in the top. Test tubes sit in a test tube rack.

                                                                                            2. Conical Flask - This is used for experiments with liquid up to 150 ml. The flask has a rubber bung for the top and the glass is heat proof.

                                                                                                     3. Glass Stirring rod - This is a 20cm glass rod used to stir and mix any liquids together.

                                                                                                4. Test tube tongs - These are used to hold hot equipment we have used after an experiment.

                                                                                                   5. Spatula - This is for holding small amounts of chemical powders.

                                                                                                6. Funnel - used to channel liquids into a smaller container.

7. Measuring Cylinder - This is used to measure liquids for experiments. The liquid we use will be poured into a beaker or test tube once measured out.
