How can the farmers use selective breeding to increase milk production? • A) By increasing the age the cows that are bred • B) By choosing cows that are high milk producers • C) By limiting the number of offspring per cow • D) By choosing cows that can produce milk after eating the most food • What was the name of the game we played yesterday (with the notecards)? • Stand Up, Pair Up, Share

15. Warm Up • A balance and a graduated cylinder are used to determine the density of a mineral sample. The sample has a mass of 14.7 g and a volume of 2.2 cm3. What is the density of the mineral sample? • 0.15 g/cm3 • 32g/cm3 • 13 g/cm3 • 6.7 g/cm3 Use your phone as a calculator Density = mass/volume

16. Using Emergency Safety Equipment • Fire Extinguisher • Remember the acronym PASS - PULL, AIM, SQUEEZE, and SWEEP. • Step 1- PULL the pin on the handle. This will allow the handle to work. Stand 8’ to 10’ from the fire. • Step 2- AIM the nozzle at the base of the fire. Hit the fuel. It will not do any good to aim at the flame tops because the chemical from the extinguisher will pass right through them. • Step 3- SQUEEZE the top lever or handle. This will allow you to release the contents of the extinguisher. • Step 4- SWEEP the nozzle from side to side

18. Using Emergency Safety Equipment • Fire Blanket • Step 1- Remove fire blanket from its container. • Step 2- Shield your face, arms and hands with the blanket by wrapping the outside of the blanket around your arms. • Step 3- PLACE, do not throw, the fire blanket on the burning material. No air should be getting to the flames. • Step 4- If it is safe, turn off the heat source causing the fire. • Step 5- Leave the blanket on the burning material at least 30 minutes. Do not remove the blanket until it is cool. • Note: If you are smothering a clothing fire you should tightly wrap the blanket around the person whose clothes are burning and roll that person on the floor in the blanket.

19. Using Emergency Safety Equipment • Face/Eyewash • Step 1- Guide injured student to the eyewash station. Because the first few seconds after exposure to a chemical are critical, eyewash/face wash must be within 10 or fewer seconds of anywhere in the room. • Step 2- Use your hands to hold the eyes open while using the eyewash to be sure water reaches the eyes. • Step 3- Flush skin or eyes with tepid water (60- 90 F) for at least 15 minutes. • DONOT RUB! • Step 4- Get medical assistance immediately.

20. Are everyday substances and chemicals dangerous? • United Streaming video link of Oil and Water in a stove

21. Science Safety • Draw this thinking map on the back of your handouts • PARAPHASE how to operate the equipment in the blue blanks Fire Blanket Eye Wash Emergency Safety Equipment Fire Extinguisher

22. Science Safety • Think about the Lab rule • What are some lab rules? • With your table group you will act out a lab rule or procedure that is either safe or unsafe. • Group Roles • Reader- reads the scenario • Actor- acts out the scenario being read • Props- Provides objects the actor can use to portray the objects being read in the scenario • Actor/Props- Does which ever role is needed • The class will then take a vote to decide what is rule is and if it is safe or unsafe. • If it is unsafe the class will explain what they should do in the unsafe situation and how to have made the scenario safe in the first place

23. Vote • Safe Unsafe

24. Homework • On a piece of computer paper make a cartoon giving an example of how to act safely in a science classroom and how to act unsafely in a science classroom. • -the cartoon must have a minimum of four colors • -there must be at least one sentence describing the scenario on each box • -label the science safety equipment • -drawings must show effort

25. Warm Up The pickup truck has a changing velocity because the pickup truck — A can accelerate faster than the other two vehicles B is traveling in the opposite direction from the other two vehicles C is traveling on a curve in the road D needs a large amount of force to move Velocity = Speed + Direction Force = Mass X Accleration

26. White Board • With your table group write the correct answer on the white board

Second, light alcohol burner with match. Third, remove test tube from rack and hold test tube with test tube clamp. Finally, when heating test tube, hold with clamp, place bottom of test tube over flame, and point the opening away from your face.

41. Triple Beam Balance

42. Can you figure out how to make the balance even? If 2 diamonds = 1 circle and 2 squares = 3 circles, what do you need to balance out 1 square?

43. Can you figure out how to make the balance even? If 2 diamonds = 1 circle and 2 squares = 3 circles, what do you need to balance out 1 square?

44. Why is measurement important? • Use it in daily life • Cooking • Construction • Decorating a room • Driving • Communication • Need to be able to communicate measurements and distances to other people

45. Measurement & Physics • Physicists try to find relationships between the quantities they measure  use units of measurement to do this • Measure the very largest and smallest things in the universe • Smallest: mass of an electron • Largest: light years (distances between stars and galaxies)

46. How to use a ruler • Determine if you are measuring in centimeters or inches and find that unit’s side of the ruler. • Place the “0” mark at one end of the object you are measuring. • Each dash after a whole inch is 1/16 of an inch • Each dash after a whole centimeter is 1/10 of an inch
