Observations is a statement of FACT. You must use one of the five senses.

An inference is an OPINION based upon prior knowledge.

Page 2: Observations is a statement of FACT. You must use one of the five senses. An inference is an OPINION based upon prior knowledge.

Inference or Observation?!

1. The hawk has brown feathers2. This pebble is round because it was

rolled down a mountain3. This plant has thorns down the stem4. The girl is sad because she is crying5. Tomorrow it is going to rain because it

will be cloudy.

DENSITY OF OBJECTS DO NOT CHANGE!If you have a piece of wood with a mass of 20g and a

volume of 10cm3

Density of this object is 2 g/cm3

What if the wood is cut in half? (m = 10g volume = 5cm3)Density STILL equals 2g/cm3

Page 4: Observations is a statement of FACT. You must use one of the five senses. An inference is an OPINION based upon prior knowledge.

Which one is more dense?

Demonstration: People in a square

How about this: Which square is more dense?

Page 5: Observations is a statement of FACT. You must use one of the five senses. An inference is an OPINION based upon prior knowledge.

What is density?

Density = mass OR mass ÷ volume.

volume

Units for density: g .

cm3

Why are these the units for density?

ALWAYS REMEMBER

UNITS!

Let’s try a density problem together

Frank has a paper clip. It has a mass of 27g and a volume of 9cm3. What is its density?

Frank also has an eraser. It has a density of 5g/cm3 and a volume of 1cm3. What is its mass?

Page 7: Observations is a statement of FACT. You must use one of the five senses. An inference is an OPINION based upon prior knowledge.

Work on these problems with your neighbor.

Jack has a rock. The rock has a mass of 64g and a volume of 2cm3. What is the density of the rock?

Jill takes the rock from Jack and drops it. The rock is now in two pieces. What is the density of each piece of rock?

Liquid Layers

Which layer has the highest density?

Which layer has the lowest density?

Imagine that the liquids have the following densities: 10g/cm3. 3g/cm3.6g/cm3. 5g/cm3.

Which number would go with which layer?

Page 9: Observations is a statement of FACT. You must use one of the five senses. An inference is an OPINION based upon prior knowledge.

Liquid Layers – Try with your neighbor

Which liquid has the highest density?

Which liquid has the lowest density?

Which liquid has the middle density?
