Science – Grade 8
Week of April 27, 2020
Student Weekly Learning Targets
I CAN describe the structure of atoms including the masses, electrical charges and locations of protons and neutrons in
the nucleus and electrons in the electron cloud. Ⓡ SCI.8.5A
I CAN identify that protons determine an element’s identity, and valence electrons determine its chemical properties
including reactivity. Ⓡ SCI.8.5B
I CAN interpret the arrangement of the Periodic Table including groups and periods, to explain how properties are used
to classify elements. Ⓡ SCI.8.5C
I CAN recognize that chemical formulas are used to identify substances and determine the number of atoms of each
element in chemical formulas containing subscripts. Ⓡ SCI.8.5D

Structure of Atoms Foldable
The main goal of the foldable is to describe what you have learned about the parts of an atom.
Must Haves:
• Name all three subatomic particles of an atom
• Include the masses, electrical charges, and location (either nucleus or electron cloud) of each particle
• Use academic vocabulary
• Include an illustration of an atom with all three particles correctly labeled

HISD Secondary Science created using Microsoft Word Table
Materials Needed:
• Paper
• Pen or pencil
• Markers or colored pencils
Research the parts of an atom on credible websites (You may use your interactive science notebook if you have it with
you.) Use your computer or cell phone to access the following websites:
• https://www.khanacademy.org/science/biology/chemistry--of-life
View any of the Elements and Atoms videos from the set to assist with understanding the parts of an atom.
• http://www.chem4kids.com/files/atom_structure.html
Read the Atoms are Building Blocks sections for information to assist you.
Use a sheet of paper and fold into three sections (sample below).
Proton Neutron Electron
Label each of the three sections with one of the subatomic particles of an atom.
Inside each section, include your Must Haves – the name of the particle, its mass, charge, location in an atom, and an
illustration of the part labeled in the atom.

Atom Model
Create a model of an atom using materials from home. Choose an element on the Periodic Table to make a model of
one of its atoms.
Guiding Questions:
• How are atoms structured?
• How do protons, neutrons, and electrons differ in their masses, charges, and locations within an atom?
• What determines an element’s identity?
Must Haves (see Rubric for Quality Student Work at the end of this day) :
• Name of the atom’s element
• Correct number of protons, neutrons, and electrons
• Labeled parts, including nucleus, electron shells, and valence electrons
• Correct locations of each part of the atom
Materials Needed:
• Paper plate (can also use cut out piece of cardboard, paper, etc.)
• Three different household materials for the protons, neutrons, and electrons. Examples include: cereal, beads,
playdoh, cotton, etc. Be creative!
• Markers
• Glue (or tape)
• Periodic Table
Use the foldable created and websites recommended from previous activity to help you construct your model. After
choosing the element, determine the number of protons, neutrons, and electrons needed for your atom. Remember to
determine the number of neutrons by subtracting the atomic number from the atomic mass!
Using your selected materials from home, arrange them on the paper plate in their correct locations (including correct
number of electrons on each level). Use the center of the plate as the nucleus. Glue (or tape) each particle onto the
plate. Be sure and label each part of the atom (see your Must Haves!)
When you have finished, explain your model to someone in your home. Describe the parts that make up the atom and
what element it represents.
Wednesday
Find the Element Game
Access the following website from your computer or cell phone:
https://phet.colorado.edu/en/simulation/legacy/build-an-atom
Download the “Build an Atom” simulation. Click on the “Game” tab on the top of the simulation.
Choose Level 1. You will use the clues (number of protons, neutrons, and electrons) for a given element and will locate
the element on the given Periodic Table. Click “Check” when you think you have the right answer. There will be five
total problems for Level 1. Try other levels when you have finished.

Organization of the Periodic Table
On a sheet of paper, create a T-chart as shown in the example below. Label one side “Periods” and the other side
“Groups.”
Periods Groups
Guiding Question: How are properties used to classify elements on the Periodic Table?
In the column labeled “Periods,” write the following prompts and complete each sentence or question:
• What are periods on the Periodic Table? Periods are ______________________.
• What similar properties do elements in the same period have? Elements in the same periods have
_________________ in common.
• Name three elements from the Periodic Table that are in the same period. ______, _______, and _____ are
elements in the same period.
In the column labeled “Groups,” write the following prompts and complete each sentence or question:
• What are groups on the Periodic Table? Groups are ___________________.
• What similar properties do elements in the same group have? Elements in the same group have
_________________ in common.
• Name three elements from the Periodic Table that are in the same group. ______, ______, and _____ are
elements in the same group.
Interactive Periodic Table
Access the following website from your computer or cell phone:
https://houstonpbs.pbslearningmedia.org/resource/phy03.sci.phys.matter.ptable/periodic-table-of-the-elements/
Click on “Launch” in the center of the Periodic Table.
Click on the “Mystery Elements” button. You will use the clues given for each of the 12 mystery elements. Drag each
“?” card onto its correct place on the Periodic Table to reveal the name of the element.
