Chemical and Physical Properties Examples of Physical Properties: color, size, weight, mass, texture

Finley has a cool camera thingy, and he's using it to show us what is up on the table in the front of the room.

What are some of the properties those objects have?

1) Magnet Properties

• Attract or repel other magnets
• Opposite poles of magnets attract each other
• Magnets attract some types of metals
• Above are chemical properties

2) Wood in Water Properties

• Wood will have same density no matter how big or small it is

3) Boiling Water Properties

• We can predict when water will boil. Water will boil in 100°. That is called its boiling point. Everything has its own boiling point. Not everything boils at the same temperature.

Challenge Task!
In small groups, we devised a plan on how to separate the following frozen mixture of sawdust, iron filings, sand, and sugar.

Task: Separate the frozen mixture

EXTRA CREDIT Task: determine the mass of every component of the mixture

Before we begin, we planned out all of the procedures and came up with a list of materials that we will need. We made sure to include a short paragraph that explains a justification of our procedure.

Questions: (1) What am I learning in terms of science and problem solving skills? (2) Why is it important?
