Monday, 5/17/17- A Day- Welcome Back from Spring Vacation!

Core Ideas:

  • Each atom has a charged sub-structure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.
  • The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states.

Learning Activities:

  1. Do Now– Get out your science notebook and add to the Table of Contents- “Protons, Neutrons, Electrons p.70” (Left Side); Head page 70 properly with “Protons, Neutrons, & Electrons-Simulation & Demonstration-4/17/17.”
  2. SimulationBalloons & Static Electricity PhET- Visualize what happens to electrons when a charged balloon is brought to a wall with the simulation. Set up page 70 with title. Cut & tape diagram to page 70. Write captions beneath each diagram explaining what happened between the balloon and the wall in the simulation.
  3. DemonstrationBalloon and Stream of Water video- On page 70, record your observations of what happened when the charged balloon was held near a stream of water and explain why it happens.

Monday, 3/6/17- B Day

Core Ideas:

  • Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms.
  • Each pure substance has characteristic physical properties (for any bulk quantity under given conditions) that can be used to identify it.

Learning Activities:

  1. Do Now- Get out your science notebook and add to your Table of Contents- “Sinking & Floating Liquids p.65” (Right Side). Head page 65 properly with “Sinking & Floating Liquids-Demonstration-3/6/17.”
  2. Demonstration (Period 4)Why does a heavier candle float and a lighter piece of candle sink? Record your demonstration observations on page 63.
  3. Model (Periods 2, 6, & 7)Answer Question 4 about density of water, wax, & a candle on the molecular level. Trim and tape the handout to page 62.
  4. Demonstration- Do all liquids have the same density? Record your demonstration observations of the candles floating on two different liquids and the density column on page 65. Tape Questions 3 & 5 to page 65.
  5. Model- Answer Question 6 about water alcohol and oil on the molecular level. trim and tape the handout to page 64.

Homework:

Period 3- Take It Further Questions 7-10 handout

Friday, 2/24/17- B Day- Wear Red for American Heart Association!

Core Ideas:

  • Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms.
  • Each pure substance has characteristic physical properties (for any bulk quantity under given conditions) that can be used to identify it.

Learning Activities:

  1. Do Now- Get out your science notebook and open to page 61. Solve the following density problem:”What is the density of the 12 g cube at the right?”
  2. Science Friday- The Bouba-Kiki Effect
  3. Demonstration– Set up page 61. There are two identical containers. One is half filled with water and one is filled with only 1 cup. By lifting the containers, which bucket has the most mass of water? Which do you think has water with the most density? Answer questions on page 61 (Think-Pair-Share).
