This is a lesson on modeling molecules and classifying matter.
Question 1
1.

Part 1: Molecules

Circle the elements (building blocks) that made up the molecules on our paper from class today.

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
Question 2
2.

How many carbon atoms make up this molecule?

Question 3
3.

How many oxygen atoms make up this molecule?

Question 4
4.

How many hydrogen atoms make up this molecule?

Question 5
5.

Glucose's molecular formula is

Watch the first 1:20 minutes ONLY of this film.


You are welcome to watch more, but that is all that is required.
Question 7
7.

Grab an item in your pantry. Take of photo of the label HERE. Circle if it contains fats, carbohydrates or proteins.

Question 8
8.

Select which complex food molecules are in your pantry item.

Question 9
9.

Which of the following statements is true about the molecules that make up our food.

Question 10
10.

Part 2: Classifying Matter

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


Question 11
11.

  • perfectly stirred chocolate milk
  • steel

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.





Question 12
12.

Build a model of an element. 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.

Question 13
13.

The best definition of an element is:

Question 14
14.

Build a model of a compound. 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.

Question 15
15.

The best definition of a compound is:

Question 16
16.

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!!!

Question 17
17.

The best definition of a homogeneous mixture is:

Question 18
18.

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

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

Question 19
19.

The best definition of a heterogeneous mixture is:

Question 20
20.

Looking back on question 7 and 8 is your pantry item a pure substance or a mixture?

Question 21
21.

Optional Extension

Watch the following film and share one thing you learned from watching it.

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.
salad
unopened soda
air
vinegar
dishwashing detergent
toy box filled with toys
salt and sand
atmosphere
homogenous mixtures
heterogeneous mixtures
