What is Science?
What is the first step of the scientific inquiry process?
Observation
Unit we use for distance in science
Meter
Centi- meaning
1/100; one one hundredth
Turn into Scientific Notation:
34,000
3.4X104
Turn into scientific notation:
8679
8.679X103
What is science? Both things!
1. Facts about the natural world
2. Step by step study of the natural world
Unit we use for time in science
Seconds
Kilo- meaning
1000
Turn into Scientific Notation:
0.000067
6.7X10-5
Turn into a normal number:
1.2X10-3
0.0012
Is is a waste of time when a hypothesis is unsupported? Why?
No: you still learn something
Unit we use for volume in science
Liters
How many millimeters in a centimeter?
10
Turn into the "normal" number
6.02X108
602,000,000 (6 zeros following the 2)
Turn into a normal number:
6.022X1023
(number of atoms in a mol, which is a chemistry thing)
602,200,000,000,000,000,000,000 (20 zeroes after the final 2)
What is a hypothesis? Must have at least two important aspects of what a hypothesis is, and not use the word guess!
(Extra throw for all three attributes)
1. What you think the answer is
2. Testable
3. Based on Evidence
How many centimeters in a meter?
100
How many years are in a century?
100- centi means 1/100
Turn into a normal number:
5.7X10-6
0.0000057 (5 zeros between the decimal and the 5)
When we say For the "X105" part of 6.5X105, what are we doing 5 times?
Multiplying by ten
What is a scientific theory? How is it related to a hypothesis?
Theory: explains the natural world
Related: hundreds of hypothesis form and support a theory
"Its just a theory..." - not a thing in science!
10
How many years do you think are in a Millenium?
1000- milli means 1/1000
What is 100?
1
When we say For the "X10-5" part of 6.5X105, what are we doing 5 times?
Dividing by 10 (Multiplying by 1/10)
