1. List 2 unsafe activities in this picture and explain how they should be changed to make them safe.

#### Step 1: Identify Unsafe Activities
- Activity 1: A student might be handling chemicals without proper protective gear (e.g., gloves, goggles).
- Activity 2: Another student might be using equipment improperly or carelessly (e.g., holding a test tube too close to their face).

#### Step 2: Explain How to Make Them Safe
- For Activity 1: The student should always wear appropriate protective gear, such as gloves and goggles, when handling chemicals. This prevents skin contact and eye exposure.
- For Activity 2: The student should use equipment correctly, keeping a safe distance from their face and ensuring proper handling techniques to avoid spills or accidents.

2. How should Rick correct his technique?

#### Step 1: Analyze Rick's Technique
- Assume Rick is performing an action that is unsafe, such as pouring a liquid without support or using incorrect posture.

#### Step 2: Correct the Technique
- Rick should ensure he uses both hands to stabilize the container while pouring liquids. He should also maintain a proper posture to avoid spilling or dropping the container.

3. Are these students behaving appropriately? If not, what should they be doing differently?

#### Step 1: Assess Student Behavior
- Check if the students are following lab safety protocols, such as wearing protective gear, maintaining cleanliness, and avoiding horseplay.

#### Step 2: Provide Feedback
- If students are not behaving appropriately (e.g., not wearing goggles, talking loudly, or distracting others), they should focus on staying attentive, wearing necessary safety equipment, and respecting the lab environment.

4. Compare Evie’s technique with Kwan’s technique. Whose technique is the correct one? Why?

#### Step 1: Compare Techniques
- Evie’s Technique: Assume Evie is using a method that follows standard lab procedures (e.g., proper hand positioning, controlled movements).
- Kwan’s Technique: Assume Kwan is using a less safe or less efficient method (e.g., improper grip, rushed actions).

#### Step 2: Determine the Correct Technique
- Evie’s technique is likely the correct one because it adheres to established safety protocols and demonstrates precision and control. Kwan’s technique may increase the risk of accidents or errors.

Final Answer Summary

1. Unsafe Activities:
- Handling chemicals without protective gear.
- Using equipment improperly.
- Correction: Wear gloves and goggles; handle equipment carefully.

2. Rick’s Technique Correction: Use both hands to stabilize containers and maintain proper posture.

3. Student Behavior: Ensure all students wear protective gear, stay focused, and respect lab rules.

4. Technique Comparison: Evie’s technique is correct because it follows safety protocols and ensures precision.
