Matter
What is matter
anything that has mass and takes up space
Define Mixture
a physical combination of two or more substances that are blended together without forming a new substance.
Define Solution
Define Conservation of Matter
states that matter is neither created nor destroyed during a change
What physical properties do iron fillings have? What physical properties do sand have?
Iron fillings: magnetic, solid, black
Sand: not magnetic, solid, orange
Define physical change
involves a change of matter in size, shape, or state that does not change the type of matter
Give an example of a mixture
Trail mix, salad, skittles
Give an example of a solution we studied
sugar water or salt water or koolade water or hot chocolate
What are the states of matter
What is a particle
Any tiny piece or amount of matter. Particles are extremly small and cannot be seen.
No, it is not empty. It is filled with matter, which is gas, it is either helium or oxygen.
What tools could you use to separate a mixture?
Spoon, tweezers, filter, sieve, etc.
How can you separate solution? Describe the tool used and the procedure.
To separate salt water you use a burner and bowl the solution. The water will evaporate and turn to gas, the salt will remain and be a solid again.
Ms. Weeks mixes 1 tablespoon of sugar into her coffee, what physical changes happen to the coffee.
The sugar dissolves into the coffee, mixing in, and becoming a liquid. The sugar is still sugar, same mass, and same volume just different state of matter.
If a balloon is full of helium, a gas.... is it completely full or partially full?
Completely full
Does a mixture form a new substance
NO
Describe the physical properties of salt and water before and after being combined.
Before combining salt is a solid and water is a liquid. After combining the solution is a liquid because the salt dissolves.
If I mix 200 grams of sugar into 900 grams of coffee, according to conservation of mass, how many grams is my total drink? Explain.
Your total drink is 1100 grams because nothing can be created or destroyed in a change. So the coffee and water mass (grams) does not change. We add up the numbers to get the total.
When mixing a pink powder Koolaide in water, what physical changes happen to the water?
The water slowly takes on the pink color of the Koolaide mix because it dissolves.
What is a model and give an example of a matter model
A model is a representation or example of something in science. The particles of matter represent particles in solid, liquid, gas that are too small to see.
When sand and water are combined in a cup, what physical properties remain the same? What rule states this?
State of matter remains the same because the sand does not dissolve. Volume and mass also remain the same according to conservation of matter.
