Physical Properties (TEKS 4.6A)
The three primary physical states of matter.
What are solids, liquids, and gases?
A combination of two or more substances where each keeps its own physical properties.
What is a mixture?
This scientific principle states that the total mass of matter stays exactly the same before and after it is mixed.
What is the conservation of matter (or conservation of mass)?
A classic example of energy transfer through touch, where knocking down one standing tile tips over the next
What is the domino effect?
An uninterrupted, complete path that lets electrical energy flow seamlessly through it.
What is a closed circuit?
This is a test to find out whether an object has a higher or lower density compared to water.
What is relative density (sinking and floating)?
A special kind of mixture where one substance dissolves entirely into another substance.
What is a solution?
One of the two primary non-dissolving mixtures in your investigations to easily demonstrate that mass does not vanish when combined.
What is oil and water (or soil and water)?
This form of energy is produced by quick back-and-forth vibrations traveling through matter.
What is sound energy?
DOUBLE POINTS!
Copper wiring is commonly used in circuits because it behaves as an excellent electrical ____________.
What is a conductor?
The metric unit used when using a triple-beam balance to measure the total amount of matter in a baseball.
What are grams?
True or False: Solutions and mixtures can be physically separated back into their original components.
What is True?
If you combine 15 grams of salt with 100 grams of water, the final mass of the solution will be this amount.
What is 115 grams?
When energy transfers through water particles, they bounce up and down to form these visible patterns.
What are waves?
Plastic or rubber coatings are wrapped around metal cords for safety because they are classified as this.
What is an insulator?
The tool used to measure the average kinetic energy of particles inside a liquid or its temperature.
What is a thermometer?
This physical property explains why sugar seems to disappear when stirred into warm water, though its physical properties remain.
What is dissolving (or solubility)?
DOUBLE POINTS!
If you mix 50 grams of dry soil with 50 grams of water to make mud, this will be the total weight shown on your balance.
What is 100 grams?
Unlike sound energy, this form of radiant wave energy does not require matter to travel through.
What is light energy?
Flipping a light switch to turn the lights off creates this kind of path, stopping the electricity.
What is an open circuit?
A physical property observed when certain metal items like iron nails are pulled toward an object.
What is magnetism?
Mixing lemon juice into water is an example of this specific type of solution combination.
What is a liquid-in-liquid solution?
When salt dissolves in water and can no longer be seen, the mass remains unchanged because matter is never ____________.
What is destroyed (or lost)?
The baseline scientific definition of energy studied in grade 4.
What is the ability to do work (or make things happen)?
A wooden spoon doesn't get hot quickly when left in boiling water because wood is an insulator of this specific energy form.
What is thermal energy (or heat)?
