What is a balance scale
Anything about an object that can be observed or measured is called a ______________ _____________. ( 2 word answer)
What is physical property.
What is matter that has a definite volume but no definite shape
Liquid
The conservation of mass/matter says that...
mass/matter can never be created nor destroyed
The amount of matter in an object.
What is mass
What tool is used to measure volume?
What is a graduated cylinder.
What physical property can be measured by using a balance scale?
What is mass
Particals move the fastest in this state of matter.
What is gas.
If the mass of a lemon is 200 grams and we cut it into 4 identical pieces, what is the mass of each piece?
50 grams
What happens when an object is less dense than water.
What is float
How do you measure the volume of an object?
(write it as a subtraction problem)
_____ - _____ =
Volume of water with the object - volume of water without the object
What physical property can be measured by using a graduated cylinder?
volume
Ice is an example of this state of matter.
What is a solid.
If we cut a lemon with a mass of 100 grams into 4 pieces that are not identical, how can we find the mass of each piece?
We would have to mass them on a balance. They aren't identical, so we can't just divide 100 by 4 pieces.
When an object sinks or floats.
What is density
A toy car has a mass of 35g
A pencil has a mass of 22g
A text book has a mass of 96g
Put the objects in order according to their mass from LEAST to GREATEST.
What is pencil, toy car, text book.
Objects that sink are said to be this.
What is more dense than water
This state of matter has no shape and has no volume.
What is gas
If we do a chemical reaction, can the total mass that we started with be more or less after the reaction happens?
NO
The amount of space that matter takes up.
What is volume.
The volume of the water is 40ml without an object.
A rock is added. The volume increases to 55ml. What is the volume of the rock?
What is 15ml
A rock sinks. A beach ball floats. Therefore we can determine the rock has more or less mass than the beach ball?
The rock has more mass than the beach ball.
These states of matter take the shape of their container and have no definite shape.
What is gas and liquid.
An ice cube has a mass of 20 grams. We melt the ice cube and its volume decreases. What is the mass of the water from the melted ice cube?
20 grams
To sort objects based on their physical properties.
What is classify
