Quest 2: Marshmallow Molecules

Q2P1: Element, Molecule, Mixture Introduction

Read the following to learn the difference between an element, molecule/compound, and mixture:

Element:

Pure elements are made up of all 1 kind of atom.
Elements can be found on the Periodic Table
Every atom will have the same number of protons.
The atoms in an element are NOT bonded to one another.
Notice the 2nd picture, there are a bunch of identical atoms just sitting

next to each other (but not bonded).

Elements have atoms that are chemically the same.

Molecule/Compound:

More than one atom bonded together
At this point in your science knowledge, molecule and compound

can be used interchangeably. But, one thing you will start to notice is that

while compounds have to be made of more than one DIFFERENT element

molecules could be made of more than one of the same element or of

different elements.

Sometimes molecules are drawn by showing where
their outer electron layers are overlapping. (the first
picture of oxygen)
Sometimes molecules are shown by drawing them as
balls stuck together. (the second picture of oxygen
and)
Sometimes molecules are shown by drawing them as
balls connected by sticks. The balls are the molecules
and the sticks are the bonds holding them together.
Notice how in both examples, there is more than one
atom that is connected in some way. This is different
than the element that did not have the atoms
connected.

Mixture:

A mix of compounds and molecules that can be separated by physical

means (ex. By sifting/straining, magnets, dissolving, evaporating, etc)

Mixtures have multiple molecules that are mixed together, but not
bonded together.
Notice in the picture of salt water to the right that there are salt
molecules and water molecules but they are not connected together.
Example Solutions: kool aid, salt water, air, brass, 14 carat gold, pop
Solute - the “thing” that gets dissolved
Solvent - the "thing" that does the dissolving

Q2P2: Marshmallow Molecule Poster

1. This project should be done in a group of 2 or 3 (not 4 and not 1). Read the directions linked here VERY carefully. The key to success in this activity is to be very detail oriented in reading the directions. Follow these directions to make your Marshmallow Molecule Poster.

When you are finished, show Mrs. Roehm your poster and get the Marshmallow Lab Questions Document (It is an actual paper.).

Q2P3: Marshmallow Molecule Q's

1. Get the Marshmallow Molecule Lab Questions document from Mrs. Roehm. It is a physical piece of paper, it is not in Google Classroom. This paper will ask you to answer questions about your poster. Here is a notes page that will help you.

Show Mrs. Roehm finished poster and questions. She will sign for Q2P3 and Q2P4 at the same time.

Q2P4: Shape Vocabulary

1. You will complete Shape Vocabulary for the words Element, Molecule, Compound, and Mixture. Remember, the actual letters of the word need to be in the shape of the definition! So, while you may have a "picture" along with your vocab word, the actual letters in the word must be written in the shape of the meaning of the vocab word.

You may want to review the definitions of these words using this text.

You have done shape vocabulary in the past. If you need a reminder how to do it - Watch this video to learn how to do Shape Vocabulary. If you remember how to do it, you don't have to watch the video.

Show Mrs. Roehm your Shape Vocabulary.
