Learning Intentions
You can graph mass and volume data for three substances to explore density further and analyze how the slope of the line relates to the density of the objects.
You can use the graphs created to determine unknown mass and volumes.
You can use significant figures rules to solve problems and the correct answers will lead you through a paper maze.
Content Standards being covered:
Student can apply data
appropriately in calculations.
26. In determining significant figures of a number, a figure (number) is always
significant if it is a unit other than zero
27. A zero is always significant if it is sandwiched between non-zero digits
28. A zero is significant if it is at the end of a number and on the right side
of a decimal point
29. When adding and subtracting, count the number of significant figures only on
the right side of the decimal to determine proper number to include in answer.
30. When multiplying and dividing, count the total number of significant figures
in each number to determine proper significant figures to include in answer.
Students can identify and evaluate types and phases of matter, physical and chemical properties of matter, various changes in matter and how those changes occur.
34. Density measure the amount of matter found in a certain amount of space and is measured in g/mL
Habits of Mind/Life skills being covered:
Applying past knowledge to new situations.
Remaining Open to Continuous Learning
Journal Entry:
Does it matter how much of a substance you use to determine density of that substance? Why?
