  3. MYP Unit Question: How can such a small thing impact our environment in such a big way? Area Of Interaction: Environment Learner Profile: Inquirers Essential Question:What makes an atom different from a molecule? Standard: S8P1. Students will examine the scientific view of the nature of matter. Distinguish between atoms and molecules. Learning Target: Today I am learning how tell the difference between atoms and molecules. This is important so that I understand the materials that make up my world . MYP Unit

  4. Agenda • Opening • Molecule Video • Work Session • Notes and Match Book Foldable • Closing • Chalk Talk

  5. Atoms: What do you recall about atoms? Atoms are the building blocks of molecules, and molecules are the building blocks of matter. Molecules are extremely small. In one spoonful of sugar there are approximately 300 billion, billion molecules of sugar! Molecules can be made up of atoms of the same element, or molecules can be made up of a combination of atoms of different elements.

  6. Work Session IAN pg. Title: Molecules Today we will take Cornell Notes and create a flip chart on Molecules. Turn to page in your IAN Notebook, title the page as Molecules.

  7. What is an Element? • An element is a pure substance that is made entirely from one type of atom that cannot be broken down into any simpler substance. • Elements are determined by the number of protons.

  8. Define: Periodic Table The periodic table is a tabular display of the elements, organized on the basis of their atomic numbers, electron configurations, and chemical properties.

  9. A one or two-letter set of characters used to identify an element. Al is aluminum C is carbon H is hydrogen O is oxygen Symbol

  10. Chemical Bond • A force that holds two atoms together

  11. Molecule • Two or more atoms that are bonded together. • O2 – two like atoms bonded • H2O – three atoms, not all alike

  12. Formula • A combination of symbols that shows the ratio of elements in a compound. • Ex. H2O

  13. Molecule foldable Book (IAN pg. ) • Take a sheet of copy paper, after TITLE: write Molecules. • Take the scissors and cut each flap from the bottom to the title box (do not cut it all the way up to the top!!). • Label each tab as follows: TITLE:

  14. TOXIC! Laughing Gas Common Formulas H2O – water NaCl - salt CO2 – Carbon Dioxide O2 - Oxygen N2 - Nitrogen HCl – Hydrochloric Acid O 3 – Ozone H2O2 – Hydrogen peroxide NO2 - Nitrogen dioxide N20 - Dinitrogenmonoxide

  15. Molecular Compounds HI hydrogen iodide NF3 nitrogen trifluoride SO2 sulfur dioxide N2Cl4 dinitrogen tetrachloride NO2 nitrogen dioxide N2O dinitrogenmonoxide 2.7

  16. Molecule foldable Book (IAN #16) • Take the glue and place a thin line on the back of the paper where it says title (do not place it on the front). • Glue it into your Ian notebook. TITLE:

  17. Atoms Building Chart - Hydrogen (H) - Carbon (C) - Oxygen (O) - Nitrogen (N) - Sodium (Na) - Chlorine (Cl)

  18. Water - H2O O H H

  19. Salt - NaCl Na Cl

  20. Carbon dioxide – CO2 C O O

  21. Oxygen – O2 O O

  22. Nitrogen – N2 N N

  23. Hydrochloric Acid - HCl H Cl

  24. Ozone – O3 O O O

  25. Hydrogen peroxide – H2O2 H O O H

  26. Make the following molecules on your own. Raise your hand when you completed creating your models. NO2 - Nitrogen dioxide N20 - Dinitrogenmonoxide

  27. Closing - Chalk Talk Using the chalk provided answer the following on your table. How can such a small thing make a big impact on our environment? Compare the formula for water and hydrogen peroxide. How does the addition of one more little oxygen atom change everything?
