Matter
What is matter?
Anything that has mass AND takes up space.
What is the first step of the scientific method?
Observation
Why is Ozone important?
What is Protects us from UV rays.
True or false: You are allowed to eat and drink in the science lab
What is False
What makes ground-level ozone have negative effects on humans?
What is ground-level ozone is a respiratory irritant, causing coughing and difficulty breathing.
What are the three most common states of matter?
Define "hypothesis."
A tentative, testable, and falsifiable explanation for an observation. Typically presented as if-then statements.
What are the two types of ozone?
What is Stratospheric ozone and ground-level ozone.
When testing for odors you should...
What is use the wafting method. Hold the chemical at arm's length and then wave your hand over it.
How does increasing ground-level ozone create a postive feedback loop?
What is it damages plants and reduces visibility, which decreases oxygen in the environment for humans. This adds to the respiratory irritation, which causes a positive feedback loop.
Give four examples in class of matter AND non-matter
Matter: desk, air, chair, whiteboard, etc.
Non-matter: thoughts, faith, light, emotions, etc.
What step in the scientific method do you test your hypothesis?
What is Experiment
How is "good" ozone formed?
What is the UV rays react with oxygen molecules. This reaction breaks the oxygen bond. The highly reactive oxygen ATOM bonds to intact oxygen molecules.
True or False: Contact lenses may be worn in place of safety goggles
What is False
What is the common name for ground-level ozone?
What is the difference between a proton and a neutron?
Proton is positively charged, while a neutron is neutrally charged.
List all 6 steps in the scientific method.
What is Observation, Hypothesis, Experiment, Observe and Record, Analyze Results, Share Results.
What does VOC stand for and which type of ozone does it effect?
What is Volatile organic compounds that affect ground-level ozone.
If you get acid in your eyes you should...
What is use the eye wash station and rinsing the eyes from the inner corner to the outside for 15 minutes.
What is the difference between carbon and ecological footprints
What is Carbon footprint measures carbon dioxide generated by activities, while natural resources used.
What form of matter are humans impacting with climate change? (Hint. We talked about this in class.)
Ozone!
What is the difference between qualitative and quantitative data?
Qualitative data: uses non-numerical data (ex., carbon footprint interviews).
Quantitative data: uses numerical data and statistics to measure variables (ex., results from carbon footprint calculator)
What type of reaction creates ground-level ozone?
What is Photochemical reaction. (could also say a light reaction and get the points.)
If there in a spill in the lab you should...
What is tell the teacher, and then clean up the spill.
What are the two types of natural resources? Give one example of each.
What is renewable (e.g., water) and non-renewable resources (e.g., fossil fuels).
