Chemistry Safety Lab
Materials:
• Graduated cylinder
• 2 marbles
• Liquids to test such as water, corn syrup, canola oil, motor oil
• Masking tape
• 1 cm ruler
• Stopwatch that is accurate to 0.1 or 0.01 seconds
SAFETY NOTE: See Texas Science Safety Manual for lab and investigation guidelines: http://www.tenet.edu/teks/science/safety/safety_manual.html Engagement: Place a wooden ramp on a stack of books. Challenge students to predict which of three liquids (syrup, water, and motor oil) will reach the bottom of the ramp first. Use one drop of each liquid. Have students write their predictions and observations in their science journals. Ask student to identify which property of matter is best represented by this demonstration. Explore:
