Mini Project #2 (Due 10/9 and 10/11)
Choice A: Find 10 recipes, 5 that are examples of mixtures and 5 that are examples of solutions. For each example, explain and describe the characteristics that make it a mixture or a solution. If the example contains traits from both mixture and solution, please indicate in your explanation.
Choice B: For each of the following: sea water, the air in the troposphere, blood, magma/lava, sedimentary rock, explains whether it is a mixture or a solution. Be detailed, be creative. Include in your explanation whether the mixture or solution contains colloids or suspensions. If it does, identify them.
Rubric for this Assignment: 20 pts
20: Assignment is complete and provides direct, clear answers to all or almost of the questions being asked. Writing is neat and reflects strong effort in doing some independent research.
15: Assignment is mostly complete and provides answers to most of the questions being asked. Writing is neat and reflects effort in doing independent research.
10: Assignment is half complete and neglects to answer some of the questions being asked. Writing is somewhat legible and reflects a minimal effort in doing independent research.
5: Assignment is incomplete and neglects to answer most of or all of the questions being asked. Writing is illegible and reflects little to no effort in doing independent research.
0: No attempt made to complete the assignment.Late work is an automatic 5 point deduction from total score. Work not turned in by 10/13 becomes and stays a 0 unless you were absent on the due date.

Week-In Review
To recap what we accomplished this week:
- We learned about three types of scientific investigation:
* Observation, using the senses to gather information about what you are studying over a period of time.
* Research, looking at information that has been recorded by other sources to gather background or current information about a topic .
* Experimenting: Testing something by changing one or more (Preferably just one) variables and observing and recording the effects.
- We wrapped up scientific method and investigations with "Articles in Science", the twenty-point activity where we read a choice article and looked for evidence that helped us identify which of the three investigation types it was.
-Our first time in the Gizmo's computer lab was a success, although we did have to work through some technical difficulties with logins. We will be fixing this so that we may continue to successfully use Gizmos as an on and off campus learning resource.
Now for what is in store this upcoming week:
- Our first lab will take place throughout this week and will focus on taking accurate measurements and the formation of solid crystals from chemical and physical changes. It is unofficially titled:"What is the effect of sugar grains on the amount of crystallization?" There will be a mini-demonstration with provided background information and a chance to look at the different shapes of various crystals (sand, table salt, epson salt, rock salt, etc.) Following this, the actual lab will give us a chance to make our own rock candy.
-The wish list for this lab still stands: Sugar, Mason Jars (to ensure that each group of students in each class has a chance to participate), wooden spoons (at least 10), unopened twine or better yet, single strand string. Thanks to those who have provided supplies from this list. They will definitely help to ensure we have enough supplies to go around for this lab.
- Our first test will be given on 9/22 and 9/23. The first mini-project will be due that week as well.

More updates/ Week-In Review
Hope everyone is ready to return to the wonderful of learning tomorrow. Here's what we learned last week in a nutshell:
- We reviewed the scientific method and its use in experimentation.
- We learned about the importance of controlled experiments: they are experiments where a researcher or scientist directly changes one thing (independent variable) to cause something else to change or be affected (dependent variable) while leaving everything else the same (control variables).
- Controlled experiments have two groups: the control group, which represents normal or unchanged conditions and the experimental group, the group that you do change or experiment on.
- We discussed why it is important to limit the number of independent and dependent variables in a controlled experiment (usually to one of each) to gain more accurate results. We also discussed that control groups and experimental groups are always needed to be able to compare results.
- Finally, we discussed that experiments are not the only scientific investigations and also are not the only investigations to include independent and dependent variables.
Now as we enter the third week, here's what you can look forward to:
- Again, the labs will start to kick in. These will focus on what we talked about with the scientific method and controlled experiments so be prepared to identify some variables.
- Math integration: We will be starting to learn about the different quantities of measurement and how to make conversions with those quantities. Also I want to educate you in the art of ....tada...graphing your measurements.
- More writing integration: We will be learning more about writing successful science research papers, reviews, and lab write-ups.
Update to the lab wish-list: Waxed paper, wooden spoons, and fresh (unopened) string or twine for the upcoming surprise lab.
For the future labs (labs we will be having over the next couple of weeks): Nestle milk (any flavor, preferably whole), tin cans with lids (such as cookie or small to medium sized popcorn tins), gallon and quart sized plastic storage bags, rock salt, spoons, Styrofoam cups, unopened drinking water.
More updates will come as we continue to venture into the new school year.

Upcoming events/ wish list update
Now for what we'll be doing.
Gizmos in the computer lab this week(I think).
The first lab of the year will be this week or next. Don't want to spoil the surprise but I will say that this lab requires glass Mason jars, preferably two-quart or bigger, granular sugar, and fresh twine. If you can donate these items, I'd greatly appreciate it.
Science Fair: Be thinking about your topic, I am asking for you to submit a topic to research and experiment on by September 18. This is to keep you from waiting until the last minute and to get the necessary paperwork filled out and turned in. You will need to begin researching your topic following that time and should be ready to start experimentation by the beginning of October. A scientific journal must be kept by all students and I will go over this in depth in class.
That is all for now. I will post more items as they approach. Enjoy your nice long weekend for now.

Hi there! I hope everyone's enjoying a nice long weekend.
Well, we are now entering into our third week of the the quarter and the school year. So far everyone's worked hard. A few things for this post:
First- Here is a list of the graded assignments that have been given so far
1) The concept map containing the following words form the Word Den: scientific method, hypothesis, controlled experiment, control group, experimental group, independent variable, dependent variable. In completing this concept map, you must make sure that you not only include all of these terms, but explain how they are related to one another.
This assignment has already been graded at 10 points. If you were absentwhen it was given, please see me to receive it.
2) The variable grid. This was a ten point assignment where you were given several pretend experiments and asked to identify the independent, dependent, and control variable for each one. This was first assigned last Monday and Tuesday
3) The Challenge Questions. These were:
Part One- Pretend you are observing the effects of fertilizer runoff on the St. John's River. Identify the independent and dependent variables in this observation. Remember that even though you are just an observer and not actually doing an experiment, both of these variables are still present.
Part Two- This time, you (pretend) are designing and writing a controlled experiment based on the observations you made in Part One. For this, you must clearly identify the following items in detail:
- What problem are you trying to solve?
- What is your hypothesis?
- Experimental Procedure-Needs to be written as a step by step process. Be sure to include your control and experimental groups. Also include your independent (what you change), dependent (what happens because of what you change), and your control (anything you let stay the same).
Those are the assignments that have been given so far.
