Step-by-step solution for: King Corn Questions.docx - King Corn Video Questions 1. Why is our ...
Let’s go through each question one by one. I’ll explain the answers clearly so you can understand why they’re correct.
---
1. Why is hot glassware likely to be mistaken for cold?
Hot glassware looks exactly like cold glassware — it doesn’t change color or shape when heated (unless it breaks). So if you see a piece of glass that’s been sitting on a lab bench, you might think it’s safe to touch… but it could still be very hot from recent use. That’s dangerous! Always assume glassware might be hot unless you know for sure it’s cooled down.
✔ Answer: Because hot and cold glass look identical — there’s no visual clue to tell them apart.

2. What should you do if you spill acid on your skin?
Acids can burn your skin quickly. The first thing to do is rinse the area with lots of water — at least 15 minutes — to wash away the acid and stop the damage. Then tell your teacher right away so they can help you get medical care if needed.
✔ Answer: Immediately flush the area with plenty of water for at least 15 minutes, then notify your instructor.

3. Where does all waste go in this chemistry lab?
In most school labs, chemical waste goes into special containers labeled for disposal — not down the sink or in regular trash. This keeps everyone safe and protects the environment. Your teacher will show you where these bins are.
✔ Answer: All chemical waste goes into designated waste containers provided by the lab — never down the drain or in regular trash.
---
4. Why must you wait until the end of class before cleaning up?
You need to make sure you’ve finished all steps safely and correctly before cleaning. If you clean too early, you might throw something away that you still need, or miss an important observation. Also, your teacher needs to check your work before you pack up.
✔ Answer: To ensure you’ve completed all procedures safely and your teacher has checked your results before you clean.
---
5. Can you eat or drink in the lab? Why or why not?
No way! Food and drinks can accidentally get contaminated with chemicals. Even if you don’t see anything spilled, tiny bits of harmful substances could be on surfaces or in the air. Eating or drinking in the lab puts you at risk of swallowing something dangerous.
✔ Answer: No — because food and drinks can become contaminated with hazardous chemicals, which could make you sick.
---
6. How many times should you read instructions before starting a lab?
At least twice! First, read them all the way through to understand what you’re doing. Then read them again while setting up, so you don’t skip any steps. Safety depends on following directions carefully.
✔ Answer: At least two times — once to understand the whole procedure, and again as you begin working.
---
7. What happens if you break a rule in the lab?
Breaking rules can lead to accidents — like spills, fires, or injuries. It also means you might have to leave the lab early, redo the experiment, or face consequences from your teacher. Labs are strict about safety for good reason.
✔ Answer: You risk causing an accident, hurting yourself or others, and may face disciplinary action or lose lab privileges.
---
8. Is it okay to taste chemicals in the lab?
Absolutely NOT. Never taste anything in the lab — even if it smells sweet or looks harmless. Many chemicals are poisonous, corrosive, or toxic in tiny amounts. Tasting = extreme danger.
✔ Answer: No — tasting chemicals is extremely dangerous and strictly forbidden. Many are poisonous or corrosive.
---
9. What should you do if you’re unsure how to use equipment?
Ask your teacher! Don’t guess or try to figure it out alone. Using equipment wrong can break it or hurt you. Teachers are there to help — asking shows you’re being responsible.
✔ Answer: Stop and ask your teacher for help — never guess or proceed without understanding how to use equipment safely.
---
10. Why shouldn’t you wear open-toed shoes in the lab?
Open-toed shoes leave your feet exposed. If you drop something heavy, spill a chemical, or break glass, your toes could get cut, burned, or poisoned. Closed-toe shoes protect your feet from all those dangers.
✔ Answer: Open-toed shoes don’t protect your feet from spills, broken glass, or falling objects — closed-toe shoes are required for safety.
---
Final Answer:
1. Hot and cold glass look identical — no visual difference.
2. Flush with water for 15+ minutes, then tell your teacher.
3. Into designated chemical waste containers — not sinks or trash.
4. To finish safely and let your teacher verify your work.
5. No — food/drink can get contaminated with harmful chemicals.
6. At least two times — once to understand, once while working.
7. Risk of accidents, injury, or losing lab privileges.
8. Never — many chemicals are poisonous or corrosive.
9. Ask your teacher — don’t guess or proceed unsupervised.
10. Open-toed shoes expose feet to spills, glass, and falling items.
