SUMMARY What did you learn about in our length lab
Was measuring in METRIC (meters) better than using USA (inches),
WHY DO WE NEED TO HAVE EXACT MEASUREMENT (remember How many thumbs)
11.
Objective: I will review length and complete my lab and practice another measurement called volume
WARMUP #9
FILL IN THE BLANKS
METER LENGTH METRIC ENGLISH
In science class, we use the ______________ system. __________ is the distance from one point to another. The metric unit for length is _________.
2 The best unit to use if we were measuring the length of a battery is km m cm mm
6 cm 3 cm 3 cm V = L X W X H L W H V = 6 cm x 3 cm x 3 cm = 54 cm 3

NOTES TWO TYPES OF VOLUME L H W Regular Irregular V=Ending-Starting V=L x W x H
22.
Irregular Object 20 ml What is the starting volume 28 ml What is ending volume Displaced volume = 28 ml- 20 ml = 8 ml Volume of rock = 8 cm 3 STARTING ENDING What is the volume of the rock

WARMUP #13 a) What is the total mass? b) Where should the riders be? OBJECTIVE I will find mass (stuff) of an object using a triple beam balance and review in metrics packet 45

What is the total mass? Where should the riders be? 172 g http:// www.ohaus.com/products/education/weblab/TBBread.html
Table 1: Practice with the KNOWN mass 50, 20, 10, 5, and 1 grams. BE COMFORTABLE!
Table 2: Measure the mass of the 5 objects. Once Mrs. DuBose checks and you have the right answer, your group will get approval and may choose 2 items each to find the mass of
Guess the mass and then actually weight it

Problem How does the starting temperature of water affect how quickly its temperature will change when 3 ice cubes are added? Controlled Hot or Cold Water Responding Temperature Change Manipulated
3 ice cubes
100 ml of water
same time period
45.
Hypothesis If ___________________________, then _________________________
Procedure:
Place 100 mL of water into the 250ml beaker.
Place the thermometer in the beaker and take the STARTING temperature of the water record in the data table at 0 minutes.
Use the tongs and place 3 ice cubes in the water and STIR.
Record the temperature every 30 seconds for 5 minutes.
Once done repeat with HOT WATER gotten from Mrs. DuBose. BE CAREFUL
