7. Do Now Mon 9.15.14 Krusty Krabs Breath Mints
Mr. Krabs created a secret ingredient for a breath mint that he thinks will “cure” the bad breath people get from eating crabby patties at the Krusty Krab. He asked 100 customers with a history of bad breath to try his new breath mint. He had fifty customers (Group A) eat a breath mint after they finished eating a crabby patty. The other fifty (Group B) also received a breath mint after they finished the sandwich, however, it was just a regular breath mint and did not have the secret ingredient. Both groups were told that they were getting the breath mint that would cure their bad breath. Two hours after eating the crabby patties, thirty customers in Group A and ten customers in Group B reported having better breath than they normally had after eating crabby patties.
1.Which people are in the control group?
2. What is the independent variable? 3. What is the dependent variable? 4. What should Mr. Krabs’ conclusion be? 5. Why do you think 10 people in group B reported fresher breath?

9. Ms. Z wants to purchase new pens for School of the Future
Ms. Z wants to purchase new pens for School of the Future. She needs to know which type of pens lasts the longest. She asks the teachers if there is a type that they like the best. Ms. Baum loves ball-point pens, Ms. Glatzer prefers gel pens, and Mr. Lynch likes felt-tip pens. Ms. Baum thinks if she buys gel pens, then they will last the longest. She purchases the three types, and she gives each type to a group of 20 students to use and see how long they last. She writes down how many words each pen can write before it dies. The group with ball-point pens can write an average of 10,000 words before the pen dies; the gel pens write 5,000 words; and the felt-tip pens last for 11,000 words. LWBAT identify the stages of this scientific method.

10. Step 1: State problem/ask question
Ms. Baum wants to know which pens last the longest
Step 2: Gather info
Ms. Baum asks the other teachers which pens they like
Step 3: Form hypothesis
Ms. Baum says, “If I use gel pens, then they will last the longest.”
Step 4: Perform experiment
She purchases the 3 types of pens, gives them to students, and records the average number of words they can write
Step 5: Analyze data
Ball-point=10,000 words, gel pens=5,000 words, felt-tip=11,000 words
Step 6: Draw conclusion
Ms. Z determines that the felt tip pens last the longest and her hypothesis is NOT supported. She rejects it.

12. EXIT TICKET
Identify the following as one of the steps from this scientific method (write E for experiment, P for problem, H for hypothesis, C for conclusion, D for analyze data, and GI for gather information)

2._____ Mr. Friedman took measurements of the mold for a month and tried to make sense of the numbers.
3._____ Ms. Meagan wondered why mold always grew in only one corner of her classroom. She decided to investigate this.
4._____ Mr. Spring’s students looked at the data and decided the mold was growing in dark places. They decided to make a graph of the data.
5._____ Ms. McCleary suggested that the lack of light in the corner might be causing the mold to grow.

15. A Scientific Method Review
Your science teacher gives groups of students 4 sets of cards/tiles. He wants to check if his students can demonstrate developing knowledge of the objectives he has taught so far by demonstrating their knowledge and ability in a group setting & to communicate results of investigations using multiple representations. Take a moment to look over the cards/tiles and determine in your group a procedure that you would use to apply to this activity. After writing the procedure in your science notebook, do it.

When they submitted their work, the teacher said that the temperature they recorded was not accurate. What should the students have done to make their data more accurate?
A. They should have conducted multiple trials to verify their first result.
B. They should have used two thermometers to measure the temperature.
C. They should have asked other groups what temperatures they recorded.

31. The study of biology requires an understanding of many technical terms
The study of biology requires an understanding of many technical terms. Sometimes you can find the meaning of an unfamiliar term by looking at its parts. In this activity you will analyze such parts to help you understand many of the terms you will encounter in biology. Many words have prefixes and suffixes that provide clues to their meanings. The following table contains a list of prefixes and suffixes that are often part of biological terms. Look at the table and study it carefully.
Use the prefixes and suffixes to form 5 biology terms.
Example Chloro - green and phyll – leaf = green leaf (substance found in)

32. DO NOW 9/22/14
Distinguish between the scientific terms: inference, hypothesis, fact, law, observation, principle and theory.

33. Distinguish between the scientific terms: inference, hypothesis, fact, law, observation, principle and theory.
An inference is like saying: All A's = B. and all B's = C. Therefore all A's = C.
A hypothesis is just an idea that is testable and can be supported or rejected by experimental evidence.
A fact is a hypothesis that has been so thoroughly tested and accepted that it is assumed to be true.
A scientific law is a statement that shows relationship between things. Ex: Gravity

34. An observation consists of receiving knowledge of the outside world through our senses, or recording information using scientific tools and instruments. Any data recorded during an experiment can be called an observation.
A scientific principle is a statement that explain the 'why' and 'how' of various phenomena.
A theory is constructed from observational data to explain that data, and to be able to predict future outcomes.
