1. Mass ~What is the difference between mass and weight? -Mass:the amount of matter in something -Weight:depends on gravity or the force of attraction between two objects Example: If we went into outer space, would we still have mass? Answer:Yes, because we are still made up of molecules What would we weigh? Answer: Nothing, because there is no gravity ~What do scientists use to measure mass? Answer: A balance ~What is the base unit in the metric system used to measure mass? Answer: grams

2. Length ~Base unit:meter Look at a ruler: The lines with numbers are centimeters. The smaller unnumbered lines are millimeters. (10 between each cm) ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 0 1 2 3 4 5 6 7 8 9 The length of the block is _____ cm. The length of the block is _____ mm. 3.6 36 NOTE: Always measure from the ________ mark, which is not necessarily the end of the ruler!!!! zero

3. Area ~Area of a rectangle =Length x Width L W 3 cm Area =____________________3cm x 3cm =9cm 2 (square cm) 5m 3m Area =_________________________5m x 3m =15m2m2

4. Temperature ~Temperature-Measures the average kinetic energy in a substance ~Scientists measure temperature with a______________________thermometer ~A thermometer is based on two points:the __________________ and __________________ points of water. freezing boiling ~Freezing point in -Fahrenheit =________________ o F -Celsius =__________________ o C ~Boiling point in -Fahrenheit =________________ o F -Celsius =___________________ o C 32 0 212 100 There are __________ o between freezing and boiling points of water in Fahrenheit and __________ o in Celsius. 180 100

5. Another system of measuring temperature is the __________ system. This is also in the _____________ System. 0 o K is the theoretical temperature at which all motion stops. This is called _______________ _______________. It is equal to __________ o C. Therefore the freezing point of water in Kelvin is _______K and the boiling point of water is _____K. Kelvin Metric absolute zero -273 273 373
