Wednesday Homework: 

Periods 1 and 4  - What's Hazardous at Home?  Read, follow procedures, HAVE PARENT OR GUARDIAN SIGN (OR GET A ZERO), then fill out the Hazardous Materials Table on the back side.
Periods 2, 6, & 7  -  w/s 4-1 What Are Three Types of Matter?  Read and answer questions. 

And, for anyone wondering, the "Challenge" is optional, or Extra Credit.  

Challenge question steps: 
1. Set up a T-Chart as shown at the top of the homework paper. 
2. Look at the substances provided by your teacher, shown below: 
3. Compare each of these substances on the Periodic Table of Elements shown on pg. 143 of your Agenda, or off of another book or  on the Internet: 
4.  If the substance for the challenge appears in the Periodic Table of Elements, then the substance is an Element and should be shown as such on your T-Chart. If not, write the substance on the Non-Element side of your T-Chart. 
5. Here are the substances: 
 Aluminum 
Cotton
Copper
Iron 
 Oxygen
Parafin wax
Stainless Steel 
 Sulf\ur





Recent Notes for students who may have missed them: 

Dec. 20, 2016 GC: Globalization & Sustainability

topic: Types of Hazards IBPC: Risk takers

Obj: TSW: ATL: Critical Thinking skills - Draw reasonable conclusions.

• learn about types of US DOT hazards
• Students learn about Department of Transportation hazard categories as they classify classroom chemicals.

Challenge: What types of hazards do certain substances pose?

Vocab: (write vocab words in notes, words + definitions in vocab section)

Corrosive - a substance that reacts with a solid material. Ex: sulfuric acid and other acids corrode metals like iron.

Flammable - a substance that catches on fire when exposed to spark, flame, or heat.

Toxic - Poisonous if inhaled, ingested or absorbed through skin. "Ingested" means swallowed. "Absorbed" means soaked up.

Topic: Handling Hazardous Materials ATL: Communication skills - take

Objective: TSW:                    effective notes in class. IBPC: Principled

1.Explain precautions taken by team in handling unknown materials;

2. Use evidence to identify type of substance.

Vocabulary (Write the words in your science notebook; write the words & definitions in your vocabulary section):

• Evidence - facts or information gathered by observation which can be used to form an idea or reach a conclusion.
• Hazardous - something that can cause harm.

• Hazardous Materials - substances that can harm living things, including humans and the environment if not handled with caution.
• Materials - substances that people use to make products; each material has unique properties. Example: gold has a shiny metallic color.

Take Away: Unidentified materials should be handled as if they are Hazardous Materials, because we don't know what they are. If you find unidentified materials, walk away and tell a parent or First Responder or another adult.
Precautions in handling unknown materials include:

• wear protective gear (goggles, gloves; Hazmat teams wear suits, boots, gloves, air supply);

• HazMat teams gather evidence to identify substance types and hazards (ex: test for flammability, pH (acid or base), radiation, etc.).

• approach and test unknown materials with caution -Assume materials are Hazardous, until materials are known.
