Senses
Quantitative observations include ____________ and/or ____________
Numbers and/ or measurements
Determine if this Observations is Qualitative or Qualitative.
"The Ice cream sundae is in a blue bowl, the Ice cream sundae is cold"
Qualitative
Explain how the molecules inside of a gas would look like and act.
Molecules inside of a gas are far part which allows them to move freely.
Boiling water is an example of a physical change, true or false? Explain what is being changed.
True, the state of the water is changing from a liquid to a gas
The state of a matter is a physical property, true or false?
True
During my experiment I saw that there was a color change, what type of observation would I take for this experiment
Qualitative
What is something both physical and chemicals changes have in common.
Both are changes in matter
Both can involves bubbles
Both involve energy changes
The molecules inside of this state of matter are in a fixed position meaning that they can not be moved meaning it has a _________ shape.
Definite
How can I tell a chemicals change has happened.
They can cause color change
Not Easily reversible
New products are formed
Formation of light, heat, sound, bubbles, or a precipitate
What is the definition of a physical property
any property of matter that can be observed without changing the identity of the matter
During my experiment I wanted to see which car was the fastest, which type of observations would I need to determine which had the fastest time.
Quantitative
True or False, boiling water is an example of a Chemical change
False boiling water is an example of physical change
Which type of change is also associated with a change of state? Physical or Chemical?
Physical Change
During the experiment on Friday Mr. Laster mixed Hydrogen Peroxide and Yeast causing a chemical change I knew this because ______________, ________________, and ________________
a new product was formed
The change was no reversible
Heat was produced
What do chemical properties tell me about the matter.
Indicates how a substance reacts with something else
During my experiment on Friday and Monday most of the observation done was qualitative. Give me an example of a qualitative observation from the experiment.
I could see bubbles being formed during the alka- seltzers and water. I could feel there was a temperature change during the hydrogen peroxide. I saw the explosion from the Coke and Mentos experiment
