MAP TAP 2002-20032 Qualitative Observations Describe an object’s qualities. Use the five senses: –Sight –Hearing –Touch –Smell –Taste Are based on facts. Describe what the object is like.

3
MAP TAP 2002-20033 You Try It! Pretend you are in this picture. Describe it using qualitative observations.

4
MAP TAP 2002-20034 You Try It! Did you remember to describe: What you would see? What you would hear? What it would feel like? How it would taste? How it would smell ?

5
MAP TAP 2002-20035 Quantitative Observations Describe quantities. Use numbers as measurements or to count. Scientists prefer quantitative observations.

6
MAP TAP 2002-2003 Quantitative and Qualitative Observations6 The Metric System Scientists use the metric system when measuring. The metric system is based on the number 10, so converting in the metric system is easy – just move the decimal point!

7
MAP TAP 2002-2003 Quantitative and Qualitative Observations7 Basic Units in the Metric System Meter –(m) – measure distance Liter – (l) – measures volume Gram – (g) – measures mass (weight)

8
MAP TAP 2002-2003 Quantitative and Qualitative Observations8 Prefixes in the Metric System Kilo (k) - base times 1000 Hecto (h) – base times 100 Deca (dk) – base times 10 BASE (meter, liter, or gram) Deci (d) – base divided by 10 Centi (c) – base divided by 100 Milli (m) – base divided by 1000 King Henry Died ByBy Drinking Chocolate Milk

MAP TAP 2002-20039 To Convert In the Metric System: Put an “X” on the amount you know. _____ ______ _____ ___X__ _____ ______ _____ K H D B D C M 36.54 m = ______ cm

10
MAP TAP 2002-200310 To Convert In the Metric System: Put an “X” on the amount you know. Put a “?” on the amount you are trying to find. _____ ______ _____ ___X__ _____ __?___ _____ K H D B D C M 36.54 m = ______ cm

11
MAP TAP 2002-200311 To Convert In the Metric System: Put an “X” on the amount you know. Put a “?” on the amount you are trying to find. Count from the “X” to the “?”. _____ ______ _____ ___X__ _____ __?___ _____ K H D B D C M 36.54 m = ______ cm 2

12
MAP TAP 2002-200312 To Convert In the Metric System: Put an “X” on the amount you know. Put a “?” on the amount you are trying to find. Count from the “X” to the “?”. Move the decimal point the same number of places in the same direction. _____ ______ _____ ___X__ _____ __?___ _____ K H D B D C M 36.54 m = _3654._ cm 2

13
MAP TAP 2002-2003 Quantitative and Qualitative Observations13 To Convert In the Metric System: Put an “X” on the amount you know. Put a “?” on the amount you are trying to find. Count from the “X” to the “?”. Move the decimal point the same number of places in the same direction. Add zeroes if necessary to be able to move the decimal point.

14
MAP TAP 2002-2003 Quantitative and Qualitative Observations14 To Convert In the Metric System: Put an “X” on the amount you know. Put a “?” on the amount you are trying to find. Count from the “X” to the “?”. Move the decimal point the same number of places in the same direction. Add zeroes if necessary to be able to move the decimal point. If the number doesn’t have a decimal point, put it at the end of the number.
