Evidence, Observations, & Theory

With your lab partner from yesterday, describe and explain the terms

• Observations

• Evidence

• Theory

Write on a sheet of paper to be collected. One paper per group. Write both names on the back of paper.

Activity: Creating a Learning Tool

Rubric (1 point each)

• Simple, memorable notes (not textbook talk).

• A diagram that aids memory and understanding.

• Examples of the topic.

• Two multiple choice questions about the topic.

We’ll do a gallery walk prior to our quiz tomorrow!

• Elements and Compounds

• Three states of matter.

• Metals & Nonmetals

I’ll assign your group one of the topics above.

Be sure to …

Include a diagram where appropriate.

List properties of each item.

Give examples from the real world.

Memory …

Elements

Commit these elements to memory:

H – HydrogenHe – HeliumLi – LithiumBe – BerylliumB – BoronC – CarbonN – NitrogenO – OxygenF - Fluorine

One key to memory …

Need to “rehearse” several different times for it to stick.

Short Term Long Term Memory

Example: http://www.youtube.com/watch?v=TwagFXAqE1U&feature=relatedOrhttp://www.youtube.com/watch?v=fpXfl0GTZ8U&feature=related (German)

The Periodic Table

Create a table to organize what we know about metals, nonmetals, and metalloids.

You should have three things listed for each.

Draw yourself as a scientist.

How do you envision yourself as a scientist?

You will not be judged on artistic talent!

- What are you doing? - What are you wearing? - With what tools?

Add five adjectives about the type of scientist you would be.

Draw a Scientist -- Discussion

What prevents many people from seeing themselves as scientists or someone interested in science?

What should we do?

Why?
