2. Vocabulary Observation: to use the senses to gather information Inference: to make a conclusion based on observations, and previous knowledge Instrument: a device used to help make observations

3. Vocabulary Classification: to group items with similar characteristics Length:distance between two points Mass: amount of matter in the object Time: the duration of an event Volume: the amount of space that an object occupies

4. Vocabulary Density:ratio of the mass of an object to its volume Cyclic change: a change in the environment that repeats itself with a reference to time and space Prediction:an inference about the future Dynamic Equilibrium: a balancing between two opposite forces

5. Vocabulary Interface:a boundary between regions with different properties Percent deviation: aka Percent error, how much a measurement is from a standard Rate of change: How much something changes over time

19. Dimensional quantities and Comparisons a.Density b. Pressure c.Volume

20. Dimensional quantities and Comparisons a.Density: mass volume Measurement using mass and volume

21. Density Pyramid DV M

22. Density of the Rubik’s Cube What happens to the density of the Rubik’s cube when it’s broken into smaller pieces?

23. Density of the Rubik’s Cube mass Has it’s mass changed? NO volume Has it’s volume changed? NO density Therefore, has it’s density changed? NO!

24. Dimensional quantities and Comparisons b. Pressure: Force on an object compared to surface area.

25. Dimensional quantities and Comparisons c.Volume: Amount of space occupied Expressed in cm 3 or ml V = l x w x h

26. ERROR NOT ALL MEASUREMENTS ARE NOT EXACT!

27. Graphing Rules to succeed

28. Axis Each axis is labeled X or Y Y X The Y axis is vertical The X axis is horizontal

29. Axis Each axis is labeled with a title Y X title

30. Reading Graphs Y X Age Years When reading a graph you say the X axis title first and the Y axis second

31. Reading Graphs When reading this you say.. Y X As X goes up Y goes up

32. Reading Graphs Relationship types Y X This is called a direct relationship Monkey see Monkey do

33. Reading Graphs When reading this graph you say… Y X When X goes up Y goes down

34. Reading Graphs Relationship types Y X This pattern is called an inverse or indirect relationship

35. Reading Graphs Relationship types Y X One goes up the other goes down “opposites”
