• Sweep up the glass.
• Pick up the glass with your hands.
• Ignore it; the teacher will clean it up when she sees it later.

What is important to remember when working with hot plates and burners?

• It's ok to walk away.

• Hot plates and burners are not dangerous.

• Hot plates and burners should not be left unattended.

Keeping your work area neat and clean is important because:

• I won't lose my supplies in the clutter.
• It keeps the room from looking messy.
• It helps prevent accidents.

I can perform my own experiments with lab materials ___.

• I am sure it is safe to do so.
• Whenever I want to.
• When all of my group is ready.
• Never.
