Foundations of Science
A way of understanding the world around us.
What is Science.
Anything that has weight and takes up space.
What is Matter.
Characteristics that describe how a substance looks, feels, acts and interacts with other substances.
These tiny pieces of matter are 10,000 times smaller than a grain of sand and make up all matter around us.
What are Particles.
This is a combination of two or more substances, but they don't change into a new substance.
What is a Mixture.
1. Observation and Question
2. Do Research
3. Make a Hypothesis
4. Conduct the Experiment
5. Analyze the Results
6. Draw a Conclusion
What is the Scientific Method.
The three states of matter are:
What is Solid, Liquid and Gas.
Color, Texture, Hardness, and Reflectivity are all...
How to particles behave in solids?
They are packed closely together and can only slightly move or vibrate.
This is a type of mixture that where one substance dissolves in another substance.
What is a Solution.
What is Lab.
The law that says "Weight is conserved, or stays the same, when matter changes states or forms."
Hint: When matter changes states it weight is conserved because no particles are destroyed or added.
What is the Law of Conservation of Matter.
The property of matter that describes wether a substance can conduct electricity is known as...
What is Electrical Conductivity.
How do particles behave in liquids like water?
They are still close together, but they are able to move around and flow past each other.
Mixtures(including solutions) DO or DO NOT form new substances.
What is DO NOT form new substances
What is the Scientific Process
This type of change is usually reversible and does not create a new substance.
What is a Physical Change.
This property of matter describes whether a substance allows heat to pass through it...
What is Thermal Conductivity.
How do particles behave when they are the air inside a basketball.
These particles would be a gas. Particles in gasses spread out and move around very quickly.
All solutions are mixtures but not all mixtures are....
What are Solutions.
In a Lab, the substance a solute is dissolved in is called the...
What is Solvent.
This type of change is not reversible and creates a new substance.
What is a Chemical Change.
This Property describes whether a substance can dissolve in a solvent, such as water.
What is Solubility.
Can you see individual particles with just our eyes.
NO, they are way too small.
Signs this has occurred are: a change in color, formation of gas, temperature change, release of light or sound.
What is a Chemical Reaction.
