What is Matter?
Subatomic Particles
Answer What fundamental forces are present in the atom? What do the forces do?
Forces behind the Sun
Answer What are the three particles that make up everything we can see?
Revisit According to your “Big Bang Theory Timeline” on your What is Time booklet, at what
time were quarks, electrons and other particles spread across the universe?
When did helium nuclei form? Draw a picture to represent this era. State what subatomic
particles are contained in the nuclei?
Science 421A
When did atoms form (nuclei and electrons)? Draw a picture to represent this era and label each
subatomic particle with its correct charge.
When did light begin to shine?
State What is Einstein’s most famous equation? What is the application of the equation? How
is it important to you?
State How are heavier elements created?
Watch and Draw View the “What is Matter?” video on the website. Draw a picture of a dying
star that shows the layers of elements it creates before it implodes.

Matter by Numbers
Answer What is the simplest chemical element?
Answer What is used to define the elements on the periodic table?
Answer with Textbook Brian Cox mentions two important elements that have played a role in
our history because of physical characteristics, these were Copper and Iron. Physical
characteristics are also known as physical properties. What are physical properties and list some
examples.
Explain What physical properties would make Copper and Iron so important that they are
linked to the raise of civilization?
Explain What do you do to turn one element into another? How is this shown on the Periodic
Table?

Draw Use the Periodic Table to create the Bohr model for Oxygen and Fluorine? Place the number of
protons and neutrons in the nucleus (like the diagrams in the app).
Figure 2: Bohr Model for Oxygen
Figure 3: Bohr Model for Fluorine
The Most Powerful Explosion on Earth
Read, Watch Reflect, Write Read about the most destructive weapon on Earth. Write about
how the applications of science and technology can raise ethical dilemmas. If you need an
example of a dilemma to discuss, watch “Frankenstein’s Monsters” which discusses a few.

Structure of the Sun’s Atmosphere
State What are the four states of matter?
Watch, Draw and Calculate “How the Universe works – Stars” from 16:55 to 19:17
http://www.youtube.com/watch?v=PrTiaOeM_Eg Draw a picture of single photon’s
journey from the Sun’s core to the Sun’s surface. Calculate the distance the photon
travelled using the “givens” in the video
Figure 4: A single photon’s journey from the Sun’s core to the Sun’s surface
Sample calculation for the distance the photon travelled. (GRASS Method needed).
Draw and Calculate Draw a picture of single photon’s journey from the Sun’s surface to
our eyes on Earth. Calculate the displacement the photon travelled.

The Periodic Table
State Who “tamed the ever-expanding list of the basic constituents of matter?” What did he
create?
Color and Label Using your blank Periodic Table, label and color (or shade) all sections of the
Periodic Table listed at the top of the page. Note: You may have to use page 184-185 in your
textbook.
Complete Using your knowledge complete the chart on the back of the sheet.
Universal Chemistry Set
State Mendeleev’s table predicted elements before their discovery. He left blanks on the table
for these undiscovered elements. Because the elements were arranged according to chemical
properties, he could predict how these undiscovered elements would behave before they were
found. How is Mendeleev’s table like a scientific model?
