Introduction to the particulate nature of matter. After introducing the concepts through videos and a ChemThink interactive, students must apply what they've learned to answer a couple of questions.
What is matter made of?
Which two particles make up the nucleus of an atom?
protons and electrons
protons and neutrons
molecules and compounds
neutrons and electrons
What is the role of an electron in an atom?
Electrons can be found inside the nucleus and carry a neutral charge
Electrons circle the nucleus and have a negative charge
Electrons circle the nucleus and have a positive charge
Electrons can be found inside the nucleus and carry a negative charge
Which of the following determines the type of element that an atom makes?
the size of the nucleus
the number of protons
how much the atom weighs
the number of neutrons
What is in between the nucleus and the electrons in an atom?
A jello-like goo
Protons and neutrons
A mushy substance similar to pudding
As you proceed through the interactive below, think about how the different particles that make up an atom behave. https://www.pbslearningmedia.org/resource/lsps07.sci.phys.matter.theatom/the-atom/#.Wyetm6dKjIU
The picture below shows a solid. In the blank box below it draw how particles are arranged in solids
The picture below shows a liquid. In the blank box below it draw how particles are arranged in liquids
The picture below shows a gas. In the blank box below it draw how particles are arranged in gases.
The flowchart below describes four different substances. Study the flowchart and answer the questions that follow.
Which of the substances X, Y or Z are made up of tiny particles?
Only X and Y
Only X and Z
Only X and Z
X, Y and Z
Refering back to the flowchart, which letter can be used to represent water?
Refering back to the flowchart, which letter can be used to represent sound?
Refering back to the flowchart, which letter can be used to represent glass?
Is Z a solid, a liquid or a gas?
Laura filled three syringes, A, B and C, with 40 cm3 of matter each. She then tried to push the plungers in. She recorded the markings the plungers were at before and after the experiment. The table below shows her findings.
Based on her findings, Laura drew two conclusions:
Conclusion 1: Syringes A and C must contain solids.
Conclusion 2: Syringe B must contain a gas.
Which of her conclusions are correct/incorrect?
Think about which states of matter have a definite volume.
Both of her conclusions are correct.
Conclusion 1 is correct, but conclusion 2 is incorrect
Concusion 2 is correct, but conclusion 1 is incorrect
Both of her conclusions are incorrect.
Explain your answer to the previous question.
