Napomena autora:

This is a lesson on modeling molecules and classifying matter.

1

This is a model of glucose (a type of sugar). Count the number of each type of atom and respond to the questions below.

carbon atoms = black

oxygen atoms = red

hydrogen atoms = white

Part 2: Classifying Matter

Add the following notes into your science journal. When you are finished please check the box.

As a group, read the following article in your breakout room to better understand mixtures in everyday life.

Criteria for Success:

  • Everyone on task during the break out time

  • Reading is an agreed, shared responsibility

  • Ask each other questions as you are working.

  • Quiet time for writing questions is provided.

  • Time is monitored well.

The video is important to watch too.

As a group, sort the examples in the article into the correct category after reading the article.

  • perfectly stirred chocolate milk

  • steel

  • salad

  • unopened soda

  • air

  • vinegar

  • dishwashing detergent

  • toy box filled with toys

  • salt and sand

  • atmosphere

  • homogenous mixtures

  • heterogeneous mixtures

Build

Use materials at home and your white board to build a model of the four classifications of matter.

For example, here are my models using push pins. You only have to make one example for each. I did two.

Build a model of a homogeneous mixture. Take a photo. Label the items.

For example, here is my model using push pins. You only have to make one example for each. I did two.

Actually my example isn't totally correct - the molecules need to be evenly mixed - the one on the right shows more green together which it shouldn't. I bet yours can be stronger!!!
