1 Vocabulary Vocabulary and Math Vocabulary Vocabulary and Math Define chemistry Answer: the study of the composition of matter and changes that matter undergoes Vocabulary Vocabulary and Math Vocabulary Vocabulary and Math What is the difference between pure and applied chemistry? Answer: Applied chemistry has can objective outside of just furthering knowledge, pure chemistry does not.
2 Vocabulary Vocabulary and Math Vocabulary Vocabulary and Math If a swimmer swims 85.4 yards in five minutes, how many feet will they swim in 70.0 seconds? Answer: 59.8 feet Vocabulary Vocabulary and Math Vocabulary Vocabulary and Math Determine the number of years in 8,350,000 minutes. Answer: 15.9 years
3 Branches of Chemistry Branches of Chemistry What branch of chemistry studies the rate of reactions and the mechanisms involved in bonding? Answer: Physical Chemistry Branches Math Problems of Chemistry Branches Math Problems of Chemistry What branch of chemistry studies compounds that contain carbon? Answer: Organic
4 Branches Math Problems of Chemistry Branches Math Problems of Chemistry If a chemist is studying the molecules inside a living cell what branch of chemistry are they working in? Answer: Biochemistry Branches Math Problems of Chemistry Branches Math Problems of Chemistry If a scientist is trying to determine what elements or compounds a rock is made up what branch of chemistry are they in? Answer: analytical
5 Branches Math Problems of Chemistry Branches Math Problems of Chemistry If a chemist is studying how water catalyzes a reaction that does not contain carbon what branch of chemistry are they working in? Answer: inorganic Why Study Chemistry Why is it important to study chemistry? Why Glassware Study Chemistry Lab Answer: Understanding the natural world, preparing for a career, being an informed citizen
6 Why Glassware Study Chemistry Lab Why Glassware Study Chemistry Lab Give an example of how chemistry is used in the natural world? Answer: will vary Why Glassware Study Chemistry Lab Why Glassware Study Chemistry Lab Give an example of a job that requires chemical knowledge. Answer: will vary
7 Why Glassware Study Chemistry Lab Why Glassware Study Chemistry Lab Why is it important to understand chemistry when making a decision? Answer: To make informed decisions when voting, etc Why Glassware Study Chemistry Lab Based on the graph below, do you think that the amount of plastics packaging in US waste will increase or decrease in the next 10 years? Explain. Waste produced (thousands of tons) Year Why Glassware Study Chemistry Lab Answer: Yes, the pattern that the data shows leads to the prediction that more waste will be produced
8 Chemistry and Society Chemistry and Society Define technology Answer: the means by which a society provides its members with those things needed or desired Chemistry and Society What does technology allow humans to do? Chemistry and Society Answer: things more quickly, or things that would otherwise be impossible.
9 Chemistry and Society Chemistry and Society How has chemistry affected the environment? Answer: by developing materials that could be biodegradable, etc Chemistry and Society Chemistry and Society How has chemistry affected the way we use and conserve energy? Answer: chemistry helps conserve by making more efficient light bulbs, and helps produce it by making solar panels.
10 Chemistry and Society Chemistry and Society How has chemistry helped the field of medicine? Answer: producing drugs to help treat diseases. Scientific Method How does a scientist usually begin to identify a problem they might need to solve? Scientific Method Answer: By making an observation
11 Scientific Method What is a hypothesis? Scientific Method Answer: Possible explanation for a set of observations or possible answer to a scientific question. Scientific Method Scientific Method What must you do before forming a hypothesis? Answer: research
12 Daily Double Scientific Method What is the difference between the independent and dependent variables? Scientific Method Scientific Method Answer: The independent variable is what the scientist controls, or what is being tested, and the dependent variable is the change observed based on the independent variable. What is the difference between a scientific theory and a scientific law?
13 Scientific Method Answer: a theory is a well-tested explanation for a broad set of observations and a law is a concise statement that summarizes the results of many observations and experiments. A law doesn t try to explain the relationship is describes. That explanation requires a theory. Glassware Lab What was the hypothesis of the Glassware Lab addressing? Glassware Lab Glassware Lab Answer: the accuracy of the pieces of glassware What was the control in the Glassware Lab
14 Glassware Lab Answer: balance, the amount of water measured in each piece of glassware (50mL) Glassware Lab What was the independent and dependent variables. Glassware Lab Answer: manipulated: piece of glassware! responding:! accuracy of that piece of glassware Glassware Lab Given the following data, what conclusion could be drawn? Piece of Glassware Volumetric Flask Erlenmeyer Flask Graduated Cylinder Beaker Average Weight of Water 50.3 grams 43.6 grams 51.2 grams 38.0 grams
15 Glassware Lab Daily Answer: will vary Double Glassware Lab Glassware Lab How could you modify the Glassware lab to measure which piece of glassware is the most accurate at dispensing the correct volume of water? Answer: measure the water in the piece of glassware and then pour it into a beaker and measure the weight of the water dispensed
