Students will understand that atoms are the smallest full unit of matter.
Students will understand that atoms are made up of mostly empty space.
Students will understand that protons are positively charged, electrons are negatively charged, and neutrons have no charge.
Students will be introduced to the concept that each proton and each neutron contains 3 quarks.
Students will be able to use the Periodic Table of the Elements to find atomic number.
KEY IDEAS
DAY 1: INTRODUCTION TO ATOMS TIME NEEDED: 1 class period of 45-60 minutes ADVANCED PREPARATION: 15-30 minutes
MATERIALS NECESSARY:• Computers with Internet connections• Interactive White Board• Atom Activity and Vocabulary Sheets from Brain Pop –1 per
student• Atomic Models Activity and Vocabulary Sheets –1 per
student• Build a Carbon Atom—Modified Activity Handout from Brain
Pop—1 per student or pair Experiment Materials:• Black Olives—6 per pair or group• Green Olives—6 per pair or group• Tapioca Balls—6 per pair or group• Sheet of Plastic Wrap—1 per pair or group• Skewers –6 per group (4 long and 2 short)
Brain Pop, a popular subscription site available to many schools. This site contains related reading/writing extensions and activities and experiments.
Open Source Digital Resources students can explore.
Common Core State Standards now focus largely on nonfiction in language arts, and sources that address the reading/writing activities are necessary.
Introducing Atoms Via Digital Sources
LESSON PLAN
Learning Targets: Students will learn that atoms are the smallest full unit of matter.
Students will watch the two segments on Atoms and the Atomic Model from Brain Pop. After each video clip, discussion and graphic organizer. After the two videos, display the Periodic Table of Elements, review how it is set up. Discuss the atomic number and how it relates to protons.
Distribute the Brain Pop Activity (modified): Build Your Own Carbon Atom. Students will build their own carbon atom using olives, plastic wrap, tapioca balls, clay and skewers. End the introduction to atoms with a short podcast, Amazing Atoms from NOVA Science Now. This brief clip puts atoms into another perspective.
Each group of 3-4 students gets the following to create their atom:For the NUCLEUS: 6 black olives (protons), 6 green olives (neutrons), 1 piece of cling wrap to form the nucleus
For the ELECTRONS and SHELLS: 6 tapioca balls (electrons) 2 short skewers (for inner electron shell) 4 long skewers (for outer electron shell) small piece of clay (to attach tapioca balls to skewers)
The big ideas are to see the parts of the atom, the shells of the electrons, and to be able to visualize that the majority of the atom is made up of empty space.
Students Create Model of a Carbon Atom
After students watch some short
videos about atoms, they are
exposed to a diagram, which
they then sketch and color code in
their Science Notebooks.
(Caution: Many think there are 4 protons and 5 neutrons, so point
out there are six of each; some are hidden)
LEARNING ABOUT ATOMS
Big ideas: Protons, neutrons,
and electrons make up the atom. Atom is mostly
empty space. Electrons have different shells.

DAY 2: COOKIES, QUARKS, AND ORDERS OF MAGNITUDE
Introducing Quarks
Diagram from: https://community.emc.com/people/ble/blog/2011/11
Inside the Atom from NOVA via Teachers Domain:http://www.teachersdomain.org/asset/phy03_vid_quark/
Each Proton/Neutron has 3 Quarks
http://www.sr.bham.ac.uk/xmm/atom1.html
Proton=2 up quarks
and 1 down quark
Neutron=2 down quarks
and 1 up quark
Up Quarks have a positive charge of +2/3
Down Quarks have a negative charge of -1/3
Math and Science
Proton Charge: +2/3 + 2/3 – 1/3 = 1 (positive charge)
Neutron Charge: -1/3 -1/3 + 2/3 = 0 (no charge; neutral)
This is a great interactive to demonstrate exponential notation with negative and positive number. Helpful with studies from atoms to the universe. http://htwins.net/scale2/?bordercolor=whiteScreencasted version of Scales of the Universe http://screencast.com/t/SnwplSVU5A

made up of smaller particles which are in turn made up of smaller particles leading into the current study of matter in the universe.
Our understanding of atoms and matter is continually being revised. Materials: Teacher computer with projector/Smartboard Student computers with Java (headphones) Mystery Boxes Rutherford simulation board, marbles, meter sticks, graph paper Student copies of any worksheets you choose to use Materials for model building (clay, cardboard, flashlights, mirrors) Materials for SPM extension activity (landscape boxes, probes,

The Lux Detector
VIDEO ANIMATION http://luxdarkmatter.org/home.html
Overview- from Berkley LUX website-The Large Underground Xenon (LUX) Experiment began with the construction and deployment of a 350 kg two-phase liquid/gas xenon dark matter detector and water shield, installed in May, 2012 in the Davis Cavern at the Sanford Underground Research Facility (formerly the Homestake Mine) in Lead, South Dakota.
A large detector is required to not only set such a sensitivity limit, but also to accumulate WIMP statistics in a reasonable time frame if a signal is detected. The LUX program will also help develop the technologies required for 1–10 ton dark matter detectors.
Liquid Xenon both scintillates and becomes ionized when hit by particles (i.e. photons, neutrons and potentially dark matter). The ratio of scintillation over ionization energy caused by the collision provides a way of identifying the interacting particle. The leading theoretical dark matter candidate, the Weakly Interacting Massive Particle (WIMP), could be identified in this way.
Day 5: Sanford Lab Learning
The project is named after Ettore Majorana, an Italian physicist who first speculated that a neutrino might be identical to its antiparticle. Understanding the electrically neutral, subatomic neutrino particle, and how rarely it interacts with other matter, has become one of the most intensive physics research projects ever attempted.
The Majorana Collaboration is assembling an array of HPGe detectors to search for neutrinoless double-beta decay in76Ge. Initially, Majorana aims to construct a prototype module to demonstrate the potential of a future 1-tonne experiment. The design and potential reach of this prototype Demonstrator module are presented.
The Majorana Demonstrator
SANFORD LAB TOUR
-Product based assessments: (Have choices for various learning modalities) Examples:
*Design a blueprint of your own detector. *Make an model of one of the proposed
atomic structures we studied. Credit the scientist who proposed the idea and write a description of how they came up with this idea.
*Make a PowerPoint on a present topic that is on the cutting edge of particle physics.
