› Warm up- what do you think the periodic table trend or pattern for density is? – It is ok if you do not know! Just make a guess!

› What is the unit or formula for measuring density?

Activity 8: Measuring Volume

Density and the Periodic Table

Formula for Density

› Mineral oil is less dense than water.

› Mercury, a liquid metal, is denser than water.

› If mineral oil, mercury, and water were mix together, what would the substance look like?

Density Extension

› Please make a new page in your notebook called “Notebook Score.” Not doing so automatically means losing points!

› I will be grading them this weekend.

Activity 7 Analysis Questions

› Physical properties- things that can be measured/observed without changing the chemical composition.– Ex: size, color, density, mass

› Density can be estimated by comparing between substances (ex: water and Lego)

› The formula for density is Density=mass/volume

› A substance that is more dense than water will sink, but a less dense object will float.

› You cannot identify the metal solids YET. Coming in Activity 10!

In Case You Missed It…

› Metric unit used to measure length:

› Metric unit used to measure liquids/capacity:

› Metric unit used to measure mass:

Metric Reminders!

› Milli-– How many milliliters are in a liter?

› Centi-– How many centimeters are in a meter?

› Deca-– How many meters are in a decameter?

› Kilo-– How many grams are in a kilogram?

Metric Reminders: Prefixes

› Please open your books to page A32

Activity 8: Measuring Volume

› How would you arrange these objects from least volume to greatest volume?

› Record your answer on Activity 8.1a Student Sheet.

Volume: How can you measure it?

› Density is mass/volume.

› How do you define volume?

Density vs Volume

› The cube below has a mass of 9 grams. Will it float or sink in water? Explain and use evidence.

Group Question

› There are 2:–Measurement and calculation

› Only for regular shaped objects–Water displacement

› For irregular shaped objects

Ways to Measure Volume

› What formula do you use to measure volume?

Measurement and Calculation

Object Cube Cylinder Bar Irregular object

Formula

Water Displacement

› Each pair should determine the volume of:– one bar– one cylinder– one cube– Then exchange objects with the other pair at their table.

› Groups of 3 work together.

› Record data on Student Sheet 8.1b
