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.
Changes in Matter
What is MATTER?
How can you describe changes in matter? What is the difference between physical change and chemical change?
What are atoms?
How can you describe something? What is the difference between physical properties and chemical properties?
Berries and Bacteria Lab: Gather the Data
Agenda for Tuesday, 6 June 2017:
Berries and Bacteria: Lab Finish Write Up
Start writing procedure for Diet vs Regular Soda Experiment
Agenda for Wednesday, 7 June 2017:
Finish Procedure for the Diet vs Regular Soda Experiment
If you finish the procedure, watch the following video on sugar, take notes. Is sugar bad? Why or Why not? Is this an easy question to answer?
The Truth about Sugar
Agenda for Thursday/Friday, 8/9 June 2017:
The Diet vs Regular Soda Experiment
WEEK ELEVEN: June 12-16
Agenda for Monday, 12 June 2017:
Finish Lab Reports/Missing Assignments
Flint Water Crisis: How Chemists are Involved?
C-Notes: Take notes on the film
EQ: What are ways chemists are involved in the Flint water crisis? How is chemistry involved?
Guiding Questions: What is the crisis? Who is impacted? How does it work? What can chemists do?
Agenda for Tuesday, 13 June 2017:
Finish any missing assignments, labs, or late work
What’s the Next Big Thing?
Watch the video and take C-Notes
EQ: What are ways that science and technology are changing our future?
What are developments in progress?
Anything we should be concerned with?
Measuring pH changes when acid is introduced in cheese making.
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.
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_______________________________________________________________.
Working independently today, you should complete the following material and place in your folder. The lab we will be completing on Thursday will be exploring a change between solid and liquid. To be prepared, understanding the following background material will be helpful.
