• Safety Goggles and Aprons

• Shorts and a Tee Shirt

• Open-toed Shoes

• Sunglasses

Answer explanation

When working with chemicals or fire, wearing Safety Goggles and Aprons is essential for protection. They safeguard your eyes and body from harmful substances and heat, unlike the other options which do not provide adequate safety.

When completing a science experiment, all students should...

• Every answer included in this question

• Know where the fire blanket is

• Be careful when dealing with flames

• Read through the procedure before completing the activity

Answer explanation

Reading through the procedure before completing the activity is crucial for understanding the steps and ensuring safety. While knowing the fire blanket's location and being careful with flames are important, the procedure is the first step.

When an experiment includes the use of fire, students must...

• Tie long hair back

• Wear a fire helmet

• Wear a wig

• Hold a match upside down

Answer explanation

When using fire in experiments, tying long hair back is crucial to prevent it from catching fire. This safety measure helps protect students from potential burns or accidents.

If you get a burn or cut while conducting an experiment, you should...

• Tell the teacher immediately

• Wait to see if something happens

• Don't tell anyone

• Ignore it

Answer explanation

If you get a burn or cut during an experiment, it's crucial to tell the teacher immediately. They can provide the necessary first aid and ensure your safety, while waiting or ignoring the injury could lead to further complications.

When conducting a science experiment, it is a good idea to...

• Add only the chemicals listed and the correct amounts

• Try things on your own without reading the directions

• Add as much chemicals as possible

• Listen to your friends' directions instead of the teachers

Answer explanation

Adding only the chemicals listed and in the correct amounts ensures safety and accuracy in experiments. This approach follows scientific protocols, preventing dangerous reactions and ensuring reliable results.

If a spill occurs during an experiment, you should...

• Report the spill to the teachers

• Clean it up right away

• Walk away silently

• Spill more

Answer explanation

If a spill occurs, it's crucial to report it to the teachers for safety and proper handling. Cleaning it up without guidance may lead to further issues, while walking away or spilling more is irresponsible.

When heating a test tube using a bunsen burner, you should...

• Keep the test tube away from yourself and others

• Hold the test tube with your hands

• Look directly into the test tube

• Hold the test tube so that whatever comes out goes straight on your hand

Answer explanation

Keeping the test tube away from yourself and others is crucial for safety. This prevents accidents from splashes or breakage, ensuring that you and those around you remain unharmed during the heating process.

Which of the following is not a requirement for burning?

• Wood

• Fuel

• Oxygen

• Energy

Answer explanation

Wood is not a requirement for burning; it is a common fuel source. The essential requirements for combustion are fuel, oxygen, and energy (heat) to initiate the reaction.

Which of the following is not an open question?

• Did the flame stay lit?

• Why is oxygen a requirement for fire?

• How does a match provide heat energy?

• Why does more oxygen increase flame height?

Answer explanation

The question 'Did the flame stay lit?' is a closed question, as it can be answered with a simple 'yes' or 'no'. The other options require more elaborate explanations, making them open questions.

Which of the following is a closed question?

• How much time did it take for the candle to burn out?

• How can we put out the flame on the candle?

• Why did the flame last longer using a candle rather than a cotton ball?

• How can we make a flame stay lit longer?

Answer explanation

The correct choice, 'How much time did it take for the candle to burn out?', is a closed question as it seeks a specific answer (a duration), unlike the other options which invite broader discussion or explanation.
