KEY IDEAS

Page 9: Physics of Atomic Nuclei  for Middle and E lementary Classrooms

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)

Page 10: Physics of Atomic Nuclei  for Middle and E lementary Classrooms

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

Page 11: Physics of Atomic Nuclei  for Middle and E lementary Classrooms

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.

Page 12: Physics of Atomic Nuclei  for Middle and E lementary Classrooms

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

Page 13: Physics of Atomic Nuclei  for Middle and E lementary Classrooms

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

Page 14: Physics of Atomic Nuclei  for Middle and E lementary Classrooms

Big ideas: Protons, neutrons,

and electrons make up the atom. Atom is mostly

empty space. Electrons have different shells.

Page 18: Physics of Atomic Nuclei  for Middle and E lementary Classrooms

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

Page 19: Physics of Atomic Nuclei  for Middle and E lementary Classrooms

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)

Indirect Evidence can be used to learn about things that we cannot see. The atom is the smallest particle you can have a substance but is itself

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

Page 48: Physics of Atomic Nuclei  for Middle and E lementary Classrooms

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.
