Teachers in Training

Today students played teacher and taught each other about ionic and covalent bonds. We also learned more about why certain elements bond better with each other= valence electrons! The valence electrons of atoms that bond should add up to 8. Here is a chart showing how elements in the same column have the same number of valence electrons, or electrons on the very edge of the atom that are involved in chemical bonds:
For Example: Lithium (1 valence e-) bonds with Fluorine (7 valence e-) because they add up to 8 to make the bond noble.

Isotopes and Ions Continued plus the Atomic Bomb

What is an isotope? It is an atom that has the correct number of protons, but the number of neutrons has changed. Carbon-14 is an example of an isotope that has 2 extra neutrons in its nucleus. Carbon-14 is used to determine how long ago different dead organisms existed.

What is an ion? It is an atom that has lost or gained electrons. Ions are charged atoms. Why don't neutrons affect the charge of an atom? Think about the charge that a neutron has.

Remember a summary is in your own words and only includes the main points.

Smelly Particles

Today in class we experienced how quickly the scent of popcorn can travel across the room. How does the scent get from the popcorn to your nose? What is the scent made out of?

Homework: What do particles have to do with smell? (2-3 sentences)

Models

The word model has many meanings in the English Language. Models which are replicas of the real thing are useful in Science. They will be very useful when we are talking about atoms in our next unit on Chemistry. Today in class we learned that there are good models and bad models. What makes something a good model? Let's looks at these two models of a car:

Homework: Look through Chapter four (pp 170-210) in your textbook. List on a separate piece of binder paper any examples of models that you see.

Buoyancy!

Today in class we will be adding to our reasons of why things float in fluids (gases and liquids). The buoyant force (bf-our best friend) allows objects to float in fluids. The bf is an upward force that goes in the opposite direction of Weight.


This diagram shows how an object has less weight when put in water. The amount of weight that it loses (the buoyant force) is equal to the weight of the water displaced by the object (Archimede's Priniciple).




Homework: Using the term buoyant force, explain how a boat floats (4-5 sentences).

Regular Solids-Catch up Block Day

Today in class we will finish the Regular Solids Density lab and the second part of class will be a catch up day to finish work for the end of the semester.
