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.

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.





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.
