3. 1) Record your homework. 2) See Mrs. Grgurina to get last night’s homework checked. 3) Read QUIETLY at your desk or complete other work

4. 1) Record your homework. 2) Keep last night’s homework on your desk and I will come around to check.

5. We know that atoms make up ALL ___________. We know atoms have a ______________ and _____________.

6.  Green and Yellow Groups will stay at their desk and learn about atoms and elements  Blue and Red Groups will go to the back tables to work on their Element Superhero or Element Cube choice activity (this is due Friday!)

7. Atoms are the SMALLEST unit of matter, but what actually makes up the atom???

9.  If an atom was the size of a football field  The nucleus would be the size of a nickel.

13. Electron Nucleus Neutron Electron Cloud Proton + - 0

14. Atoms also make up ELEMENTS. What do you already know about elements?

15. Element :  a pure substance made from ONE type of atom.  building blocks for all the matter in the world.  Examples : iron, oxygen, hydrogen, gold, and helium. (Record at least two!)

16.  The element gold is made up of gold atoms. All gold atoms are similar to other gold atoms because they have the same properties.  The element iron is made of iron atoms. Iron found on Earth is the same as iron found on Mars because they are both made of iron atoms!

17. Do you think iron atoms are the same as gold atoms? Both are atoms, but iron are different from gold atoms, because they are made of iron atoms.

18.  There are over 100 different elements that make up all living and nonliving things!

20.  The number of protons determines the atomic number in the periodic table of elements.  Example Hydrogen has a 1, so it has 1 proton.

21.  The number below the symbol is the atomic mass. That is the mass of the protons and neutrons.

23. How are these two elements different??? What do you notice?

24. They have a different number of protons AND a different atomic mass! # of protons Atomic mass

25. 1) Log onto a Chromebook jsmith1234@cms.gaggle.net YYMMDD 2)Go to our class website: mrsgrgurina.weebly.com 3) Find the tab titled Periodic Table Work 4) Read and follow all directions!

26. 1) Record your homework 2) Share your homework with Mrs. Grgurina 3) Read at your desk or work on another assignment until we begin class.

27. 1) Record your homework 2) Keep your homework on your desk so Mrs. Grgurina can check it!

28.  Red, green, and yellow groups will play a choice game today to prepare for tomorrow’s quiz.  Blue group will continue their playlist (element superhero or cube). If you choose to do a cube and finish folding it, you may choose another element OR join a group’s game.

29.  Choice games:  BOOM! OR Snakes and Ladders  For each game, you will find the directions on the back counter.  Work respectfully with your group.  Please take care of all materials and when you are finished, return them exactly as you found them  Finished? Grab a study guide from the front counter and read the directions carefully!!! You may work PIG (partner, independently, group)

30.  What is an atom?  Explain what makes the atoms of the element carbon different from the atoms of the element oxygen. Write complete sentences.  Explain what makes the atoms of the element carbon similar to the atoms of the element oxygen. Write complete sentences.  Define the terms mass and volume. Identify two objects with a different mass but similar volume. 

31.  What is the relationship between atoms and elements?  One of these statements is false. Circle the false statement. Then, write at least once complete sentence explaining why it is false.  Most matter is made of atoms, but some matter is not.  All carbon atoms are the same.  Atoms are the smallest building blocks of matter.  All matter has mass and volume.  How many elements make up living and nonliving things?  Using the following words, record all examples of matter (hint: 5):  Mr. SudimackairHappychicken  desk  prettyAtomyellow
