BELL RINGER 8-19-15 WRITE THE QUESTION AND THE ANSWER 1. What was the temperature on the first day of March? A. 30 B. 75 C. 35 D. 40 2. If you compared the temperature on the first day of October with the first day of January, you would find the temperature A. went down. B. stayed the same.

C. rose slightly. D. rose a lot. BELL RINGER 8-19-15 A shopping mall wanted to determine whether the more expensive Tough Stuff floor wax was better then the cheaper Steel Seal floor wax at protecting its floor tiles against scratches. One liter of each brand of floor wax was applied to each of 5 test sections of the main hall of the mall. The test sections were all the same size and were covered with

the same kind of tiles. Five (5) other test sections received no wax. After 3 weeks, the number of scratches in each of the test sections was counted. 1- What is the Problem? WHERE CAN WE FIND ATOMS?- OPENING Take a look at your neighbor. Look very closely. Can you see any atoms? No? Look closer! If you had super x-ray abilities you

would be able to see that a bunch of things that look something like this. WHAT ARE ATOMS? Atoms are very tiny particles that form the building blocks for all matter CAN WE SEE ATOMS?? A very good question. The answer is Yes. And No. The reason for No is that it is actually

impossible for anybody to "see" an individual atom, since all atoms are thousands of times smaller than the smallest light waves we can see using our eyes. The reason for Yes is that, even though they cannot be seen directly with our eyes there is so much evidence for atoms, and we know so much about them, that it is impossible to say they do not exist.

foldable. Fold in half lengthwise (hamburger fold) Open and fold each side to center fold. Now fold it in half twice so that you have four lines going across your foldable. LABEL THE FLAPS THE FOLLOWING Atom

Electron Atomic Structure Atomic Number Atomic Mass Proton Neutron Periodic Table

WORK SESSION GRAPHIC ORGANIZER You will have 10 minutes and 10 minutes only to work with your group to make a poster depicting parts of the atoms. Your poster must include the following information: 12345- A title A description/definition (

A visual representation (thats a picture) Why it is important 2 interesting facts WORK SESSION You will have 20 minutes to quietly travel to each poster and fill in your graphic organizer. It MUST INCLUDE the FOLLOWING INFORMTION 1- Description/ definition 2- Picture 3- 2 interesting facts

You will start at your poster and then move on to the next poster. ( I will not use a timer to tell you when to move on- you go at your own pace- but when 20 is done it is over) This is an individual activity and YOU CANNOT TALK TO ANYONE!!! Click icon to add picture O P P

G N I N S I O A CL R B ATOMS

Atoms are basic building blocks of matter. They are made up of three basic particles, protons, neutrons, and electrons. ATOMIC STRUCTURE Atoms are broken up into two distinctive areas: the

nucleus which has the protons and neutrons and the electron cloud which has ELECTRONS. Clou d PROTONS

Small positively charged particle in the nucleus of an atom. NEUTRONS Particles with NO CHARGE, they are neutral. o

o Tiny, NEGATIVELY charged, high energy particle that moves in the space outside the nucleus of an atom called the electron cloud. Electron -e

-e -e Nucleu s -e -e ATOMIC NUMBER

The number of protons in the nucleus of an atom. The number of PROTONS determines what the element is. (remember this from the video?) In a stable atom (no charge), there must + be an + equal numbers of+protons

ATOMIC MASS (WEIGHT) The average mass of one atom of an element ( number of Protons and Neutrons). # of Protons + # of Neutrons = Atomic Mass NP P N NP

Elements and the Periodic The periodic table Elements Tableare chemically the simplest substances and they cannot be broken down using chemical methods

They have all the same atoms. organizes elements on a big grid based on an elements properties. Each element is placed in a specific location because of its atomic structure. The periodic table brings

order to information about the chemical
