Year 8 AEP Week 1 Safe, accurate and ethical laboratory skills and techniques
Task 1 Past Science class experiences
- In about half a page describe one of the most interesting science lessons that you have participated in. Explain why you found it interesting.
- In about half a page describe one of the most boring science lessons that you have participated in. Explain why you found it boring.
Students at tables in rows 1 and 3 turn around and join the students at tables in rows 2 and 4. In your new cluster take turns to introduce yourselves to each other and read your answers.
From each cluster choose one of either the most interesting or most boring to read to the class.
Task 2 Mapping the laboratory, locating apparatus and scientific drawings
Before working in the laboratory students must be familiar with the whereabouts of the science apparatus and safety procedures.
- Measure the perimeter of the laboratory.
- On graph paper provided, draw a scale diagram of you science laboratory, noting the position of side work benches, windows, doors, sinks, gas taps, shelving of apparatus, cupboards of apparatus and drawers of apparatus.
- Record the position of the safety buttons for the gas and electricity. Note also the position of the fire extinguisher, fire blanket and safety glasses
- You can draw in the 16 student writing tables and the front teacher demonstration bench.
- Record as a label and an icon where the science apparatus is kept.

Task 4 Meet the elements
Watch this short video http://www.youtube.com/watch?v=d0zION8xjbM
- Write the date of viewing and the title of the video.
- Summarise, or draw diagrams to describe three of your favourite elements from.
- Write at least two questions that arise from the ideas discussed in the video.
- If you have time, research the answers to your questions and bring them to class for discussion.
Task 5 A physical property - DENSITY
Students will find the mass of objects using the triple beam balance. They will find the volume by displacement of water in a measuring cylinder. From this the density may be calculated.
Density = mass / volume
Density = mass / volume
