Presentation transcript:

On page 10 of your notebook, predict how the layers will form. Which one will go at the bottom? Which one will go on top?

DENSITY is the amount of MASS contained in a given VOLUME of some material.

The following boxes are the same volume. Assume all the balls have Equal mass. Which box is more dense?

The following boxes are the same volume. Assume all the balls have Equal mass. The box on the LEFT has GREATER DENSITY than the box on the right because is has MORE MASS IN THE SAME VOLUME

DENSITY is the ratio of an object’s MASS to its VOLUME.

Calculating density with known mass and volume: determine the density of a material that has a mass of 36g and volume of 2.5 cm 3.

Calculating volume with known mass and density: find the volume of 50g of olive oil if the density of olive oil is 0.80g/mL.

Measurement Activity Reading Lab Equipment

Measuring Volume We will be using graduated cylinders to find the volume of liquids and other objects. Read the measurement based on the bottom of the meniscus or curve. When using a real cylinder, make sure you are eye- level with the level of the water. What is the volume of water in the cylinder? 43 mL

Measuring Solid Volume 10 cm 9 cm 8 cm We can measure the volume of regular object using the formula length x width x height. 9cm X 10 cm X 8cm = 720cm 3 We can measure the volume of irregular object using water displacement. Amount of H 2 O with object = 200mL About of H 2 O without object = 260mL Difference = Volume = 60mL

Units of temperature: Kelvin (K) Degrees Celsius (°C) Degrees Farenheit (°F) Measuring Temperature Measurement of the average KINETIC ENERGY of the particles of an object What is the temperature? Thermometer A: ___4°C____ Thermometer B: _____48°F_____

Measuring Length What is the length of the line in centimeters? 3.3cm

Measuring Mass We will be using triple-beam balances to find the mass of various objects. The objects are placed on the scale and then you move the weights on the beams until you get the lines on the right-side of the scale to match up. Once you have balanced the scale, you add up the amounts on each beam to find the total mass. What would be the mass of the object measured in the picture? 300 g + 30g + 5.3g = 335.3g
