What is matter?
The material or “stuff” everything is made of.
What are you doing if you are observing matter?
Observing matter means to carefully explore all of its properties.
Look around the room and identify some matter.
What are some physical properties matter can have?
Color, texture, odor, shape…
What are two properties that all matter share?
All matter has mass and takes up space.
What did we just use to observe properties of matter?
Sight - Looks
Touch - Feels
Hearing – Sounds
Odor – Smells
Quantitative ObservationsWhatdo we use to help us observe?
Choose an Object to Observe
Choose an Observation Type
List as many properties as you can about that object.
What do you observe about that object quantitatively?
What are all the things you observe directly about….?
Describe how this object looks, feels,
sounds, and/or smells.
Drop of Water
(solid, liquid or gas)
Equipment Needed: lab sheet, container of water, flashlight, magnet, circuit (lightbulb & wires & battery in a holder connected)
Procedures: Read the test below and predict which properties apply to your group’s six objects. Then conduct the following tests using materials provided in order to identify which properties apply to your group’s six objects. Record results on chart. Compare predictions to results.
Bonus: Try to think of a new way to classify your group of objects based on the test results.
Investigation Two Make predictions, test and then record test results on lab sheet chart. Compare. Last add an opposite for each property.
(solid, liquid or gas)
Conductor of electricity
Ability to sink or float in water
Ability to Dissolve in a liquid or solubility
What do we call characteristics that can be observed, measured, or changed without changing the object itself?
They are the things that do not change about an object unless you change the material.
Try out the questions below:
4. Decide on what would be a good material.
and their properties.
