• Lab safety - Occupational Health and Safety issues
• Equipment - know how it works, model technical skills, know when to call for technical help
• time constraints - specific tasks need to get done at a certain time, being productive during gaps
• students may want to leave early, plan and organise to finish in a timely manner
• need to deal with unexpected results
• as there is assessment of labs, need to cover all topics and material
• divide up tasks but ensure that all students develop all skills

• start from beginning, find out why the unexpected results occurred
• go back over the process, how did the unexpected results occur - operator error, problems with equipment
• if lab carried out properly and still unexpected results - further research
• repeat critical steps
• involve whole group
• report the unexpected results to someone

• Demonstrate practical skills
• Equipment
• Safety in labs
• Occupational Health and Safety
• Different rates of finishing lab
• Different experiments - know material - understand them
• Experiments don't always work
• Longer time - enthusiastic for the whole time
• Signing off work while keeping everyone occupied -> management
• Preparation

• Finish experiment in fixed time
• Occupational Health and Safety issues
• Awareness
• Repititious
• Equipment
• Different tasks
• Follow on problems - if early errors
• Practical - developing procedures

• Safety issues
• Autonomy - organising, being independent
• not as much freedom to plan lesson
• multitasking
• hands-on equipment
• larger numbers, increased noise, increased activity
• more diverse activity
• keeping track of all students
• key questions
• getting students to prepare for the lab sessions e.g. using quizzes
• show by example - be prepared
