25 questions!!

Chapter 1

Convert the following measurements to the new unit!

a)10L = ______mL

b)_____km = 35,000 cm

c)1.56 dg = ______mg

Please put the units to these units. The units should be SI and not American standards

Mass = _________

Length=________

Time = _________

Volume =________

Identify these key steps of the scientific method ( 5 in all )

•Does consumption of ice cream increase height?•There is no relationship between consumption and bone growth•20 kids were given ice cream every night for 5 years, 20 other children were given sherbert

The group with ice cream had an average growth advantage of 0.30 in above the control group

•There is a correlation between ice cream and bone growth•Although the sample size was small, there seems to be a correlation

between ice cream and bone growth. Limitation of the study would be based on etc, etc, etc……

� Fill in the blank with the missing variable or unit that matches.

� a) Time = ________� b)______ = Liters� c)______ = meter� d) Area = _________

� Draw the 4 main graph types we learned I our excel activity !

linear parabolichyperbolic

Root curve

Key to quiz 1. 4 sig figs because an area is base times height. Since the answer

has 4 sig figs, both base and height must have been 4 sigs each (rule of multiplication/ division).

2. 10,000mL, 0.3km , 156 mg3. Kg m s L

4. 2 sig figs (other zeroes are place holders)5. Problem-Hypothesis-Experiment –Accept/Reject Hypothesis-

Conclusion6. a) seconds b) Volume c) distance d) meters2
