Density is a measure of the amount of matter in an object
What is density?

Weight is a measure of gravitational force in an object.
What is weight?
100
Observation, question, hypothesis, experiment, analyze results, and draw conclusions.
What are the steps of the scientific method?
200
Mass is the amount of matter in an object
What is Mass?
200
length x width x height
What is the formula for volume?
200
Density is measured in g/cm3 for solids and g/ml3 for liquids.
How is density measured?
200
Weight is measured in newtons.
What is the measurement of weight?
200
You need to redo the experiment and change some variables to match the results with your hypothesis.
What do you do if the results did not match your hypothesis?
300
Matter is the amount of mass in an object.
What is matter?
300
By dividing the mass and density of an object.
How do you find the volume of an object, knowing it's density and mass
300
The formula to calculate and find density is mass/volume= density.
What is the formula for density?
300
There are many devices such as spring scale, bathroom scale, and etc.
What are all the measurement devices used to find weight?
300
The mass is less than the volume, the object will float. The mass is greater than the volume, the object will sink.
What is the relationship between mass and volume whether it will sink or float?
400
Everything is matter except for light and sound.
What objects have matter?
400
Graduated Cylinders are used to measure liquid volume when accuracy is important.
Which lab equipment is used to measure liquid volume when accuracy is important?
400
A tomato is more dense. Tomato and pile of feathers has same mass but tomato has less volume than the pile of feathers and so it is more dense.
Which is more dense, tomato or pile of feathers? Explain.
400
Yes, because on the earth there is more gravitational force than on the moon.
Would objects weigh less on the moon than on earth? Explain.
400
All the floating object's density is less than 1 which makes the object float. All the sinking object's density is more than 1 which makes the object sink.
What do you notice about the floating and sinking objects?
500
By using triple beam balance, the mass of an object can be determined.
How do you determine the mass of an object?
500
By water displacement.
How can you determine the volume of irregular shaped objects?
500
No objects containing the same amount of mass can take up different amounts of space.
Do objects of same mass have same volume?
500
1 newton is 1/4 pound.
How many pounds is 1 newton?
500
The object will have neutral buoyancy.
What happens if the object's density is the same as water's density, which is 1?
