Performance Standards/ Disciplinary Core Ideas / Science & Engineering Practices:
MS-PS1-1 Develop models to describe the atomic composition of simple molecules and extended structures
MS-EtS1-1 Define the criteria constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
SEP: Developing and using Models: develop a model to predict and / or describe phenomena.
SEP: Asking Questions and Defining Problems
CCC: Scale, Proportion and Quantity
CCC: Influence of Science Engineering and Technology on Society and the Natural
Today in Class:
1. Students reviewed and completed their Golf Ball Floating and Sinking Lab…. you should have applied the above Benchmarks and Standards to your lab work. You were also asked / and you answered multiple review questions.
Phenomena: Periodic Table Explore!! (paper copy14-15 & interactive online):
Name 5 elements and their uses! GO!
2. Diagram / Sketch Notes: Types of Matter: What is an Atom? Molecule? Element? Compound?
3. “Diagram / Sketch Notes” examples: we use this kind of notes – sketching and diagramming to help us to remember and understand the concepts. Look at these examples of Diagram / Sketch Notes: (NO, do not just copy these!)
Students worked with a partner. You just started this in each class.
Goals: a. Define & describe atoms, molecules, elements, compounds.
a. Draw at least 2 diagrams or sketches for each concept
b. You may refer to your reading strategy (last night- Atoms & Elements); pages 8-11, Chem. text for definitions and descriptions; p. 30 (copy of 2nd Chem text) video diagram for proposed models of atoms: https://youtu.be/_lNF3_30lUE?t=264
Homework —- Take-Away Tasks: Study Chemistry notes (metric measure., C & P Properties, esp. density, solubility)… quiz tomorrow.
