Step 1: Identify Lab Safety Rules

The task asks you to read each statement and color the bubble green if it is a lab safety rule, or blue if it is not. Here are the statements:

1. Don't talk to strangers.
- Not a lab safety rule. This is more of a general safety tip and not specific to laboratory settings.
- Color: Blue

2. Repeat any spills right away.
- Lab safety rule. Spills can be hazardous (e.g., chemicals, glass shards), so cleaning them up promptly is crucial.
- Color: Green

3. Wear safety goggles during all experiments and activities.
- Lab safety rule. Safety goggles protect your eyes from chemical splashes, flying debris, and other hazards.
- Color: Green

4. Eat three meals a day.
- Not a lab safety rule. While eating regularly is important for health, it is not directly related to lab safety.
- Color: Blue

5. Do not eat or drink anything in the science lab.
- Lab safety rule. Eating or drinking in a lab can lead to contamination or accidental ingestion of harmful substances.
- Color: Green

6. Wear shoes that cover the toes.
- Lab safety rule. Closed-toe shoes protect your feet from spills, broken glass, and other potential hazards.
- Color: Green

7. Wear gloves during experiments.
- Lab safety rule. Gloves protect your hands from chemicals, sharp objects, and other dangerous materials.
- Color: Green

Step 2: Explain Why Three Lab Safety Rules Are Important

Choose three lab safety rules from the list above and explain why each is important. Here are three examples:

1. Repeat any spills right away.
- Importance: Spills can create slippery surfaces, leading to slips and falls. They may also contain hazardous chemicals that could cause burns, poisoning, or fires if left unattended. Prompt cleanup minimizes risks and ensures a safe working environment.

2. Wear safety goggles during all experiments and activities.
- Importance: Eyes are highly sensitive organs, and exposure to chemicals, fumes, or flying particles can cause severe injuries or blindness. Safety goggles provide a barrier against these hazards, ensuring eye protection.

3. Do not eat or drink anything in the science lab.
- Importance: Labs often contain chemicals, dust, or other contaminants that can be harmful if ingested. Eating or drinking in the lab increases the risk of accidentally consuming these substances, which could lead to illness or poisoning.

Step 3: Analyze Professor Bob’s Actions

The image shows Professor Bob performing an experiment. Circle or color each example of lab safety shown by Professor Bob. Here are the observations:

1. Professor Bob is wearing a lab coat.
- Safety Rule: Wearing a lab coat protects clothing from spills, chemicals, and other hazards.
- Action: Circled or colored as a lab safety practice.

2. Professor Bob is holding a test tube with one hand while writing with the other.
- Safety Rule: Proper handling of equipment reduces the risk of dropping or breaking glassware, which could cause injury.
- Action: Circled or colored as a lab safety practice.

3. Professor Bob is wearing safety goggles.
- Safety Rule: Safety goggles protect the eyes from chemical splashes, fumes, and other hazards.
- Action: Circled or colored as a lab safety practice.

4. Professor Bob is using a notebook to record data.
- Safety Rule: Keeping accurate records helps ensure proper procedures are followed and reduces the risk of errors.
- Action: Circled or colored as a lab safety practice.
