What is matter?

We are going to take some time to explore matter.  We will break into groups of 2-4 people and each person will research one of the following realms.  We will group back together and then each group will share out what they discovered.  Each group will produce a poster that will help describe matter. 

  1. Matter/Atoms
  2. Changes in Matter
  3. Describing Matter

 

What is MATTER?

How can you describe changes in matter?  What is the difference between physical change and chemical change?

Physical Change

Chemical Change

 

What are atoms?

 

How can you describe something?  What is the difference between physical properties and chemical properties?

  • To be able to know how dilution affects the pH level of the given substances
Investigating the pH level of the 11 different basic substances

If you finish the lab, you can start watching the NOVA video below.  Color the periodic table with the similar family types.

Elements that make up our world: Hunting the Elements

We’re talking about acids and bases, but lets back up a bit and look at the atoms that are the building blocks of the molecules that then make up everything around us.

Agenda for Friday, 19 May 2017:

Measuring pH changes when acid is introduced in cheese making.

Acidic Milk Lab

Measuring pH changes when acid is introduced in cheese making.

Key Terms:

independent variable: A variable is any factor, trait, or condition that can exist in differing amounts or types.  The independent variable is the one that is changed by the scientist.

acid: Any chemical compound that will raise the amount of hydrogen ions (H+) above the amount of hydrogen ions found in water

base: a solution that has an excess of OH- ions above the amount of hydroxide ions found in water.  Another word for base is alkali.

Hydrogen ion: A hydrogen atom that has no electrons, and therefore has a positive charge.  It is highly reactive.

pH: A scale that measures how acidic or basic a solution is. The scale measures from 0 to 14, with water a neutral substance with a pH of 7.

BIG QUESTIONS:

Instead of predicting an exact value, for this experiment we will be predicting a relationship. In other words, what is going to be the trend of the data that we are about to collect?

For this experiment, what do you think will happen to the amount of cheese as we increase the amount of acid used? Will it increase or decrease? Make a hypothesis stating whether you think the amount of cheese will increase or decrease as we use more acid to make our cheese. Make sure your hypothesis includes an explanation of why you think this will occur.

Hypothesis (may look like this)

I think the amount of cheese will __________________________ (increase or decrease) as we use more acid to make our cheese, because_______________________________________________________________.

DATA

Acid Used    /   Amount of Cheese Created
