**Can you list the steps to the scientific method?**It will be on your first test State the problem 2. Gather Information 3. Form a hypothesis 4. Test the hypothesis 5. Analyze data 6. Draw conclusion**What is missing ?**What do you think of when you hear 32 degrees 32◦ ___ (SCALE) Fahrenheit, Celsius, Kelvin United States Scientist & majority other countries Measures VERY high Or VERY low temps. 32◦ Fahrenheit 32◦ Celsius = 89◦ Fahrenheit 273◦Kelvin**A. Standard- exact quantity that people agree to use for**comparison B. Measurements must have a number and a unit .**1. SI – (International system of standards) an improved**version of the metric system used and understood by scientists worldwide. 2. SI system is based on multiples of 10 and uses prefixes to indicate a specific multiple.**Lengthis measured using a unit appropriate for the distance**between two points. SI unit – meter (m) • Volumethe amount of space an object occupies. SI unit – liter (L)**Mass - measured of matter in an object. SI unit = kilogram**(kg) What’s the difference between mass and weight? Mass = measure of matter (amount of “stuff” you are made up of)… your mass stays the same whether you are on Earth or the moon or Neptune Weight = mass + gravity pulling on that object …so you would weigh less on the moon since there is less gravity http://www.exploratorium.edu/ronh/weight/ Mass =Triple beam balance Weight Scale**What do you have to do with Italian salad dressing before**using it? 1. Density - mass per unit volume of a material. 2. A unit obtained by combining different SI units is called a derived unit. Example: g/cm3 less dense**Time is the interval between two events;**The SI unit for time is seconds (s) G. Temperature is measured using a thermometer. The SI unit of temperature is Kelvin (k)**1**2 3 MetersLitersGrams How do you use the “ladder” method? 1st – Determine your starting point. 2nd – Count the “jumps” to your ending point. 3rd – Move the decimal the same number of jumps in the same direction.
