Assignment #9 (due 10.19)

Please finish the NOVA campus map you began working on in class today.  Remember that your map should be created from the "bird's eye view", as detailed as possible, and in color.  Do your best!

Assignment #8 (due 10.18)

Please compose a conclusion for your barnacle investigation.  Use the 5 questions discussed today as a guide for what to include (you can use the conclusion handout you received in class for help).  Each of the five components of your conclusion will be worth 2 points; this assignment is worth 10 points total and will be collected.  Do your best!  :)

1.	Purpose restated	2 pts
2.	Hypothesis restated (supported, partially-supported, or not supported?)	2 pts
3.	Major findings stated (refers to the data collected)	2 pts
4.	Suggestions to improve the lab procedure	2 pts
5.	Suggestions for lab extensions	2 pts

You may write or type your conclusion.  Due on Tuesday, October 18th.

No assignment, but...

Please bring your completed data table from today's barnacle investigation back to class tomorrow.  Be sure you have (1) entered correct headings for each column, (2) calculated your means for each barnacle group tested, and (3) recorded your qualitative observations.  We will use this information in class to work on writing a good conclusion and reflect on the experience of working with the barnacles.

Assignment #7 (due 10.12)

Please suggest and write an appropriate procedure (list of instructions) for your barnacle feeding rate investigation tomorrow.  Think about the activity we did in class today that focused on the importance of writing good instructions that others can follow.  Consider the steps that should be taken by your group to prepare and carry out your experiment, as well as the materials that will be needed to do so.  Think about the number of trials you will perform and how you will collect your data. A strong experimental procedure is detailed, well-ordered, and describes quantities. It should be simple and easy to follow.  Do your best!  You will have time to share, combine, and modify your procedure with your group tomorrow in class.

The manipulated variables and materials for groups in each section are listed below.

Section 3:
Sean, Graham, Eliana: Type of food (Materials: 2 types of fish food, barnacles, Puget Sound water, glass containers)

Charlie, Gabriel, Nirja: Water temperature (Materials: Puget Sound water, ice bath, hot plate, thermometer, barnacles)

Sarah, Molly, Harvest: pH level (Materials: pH buffers, pH strips, barnacles, glass containers Puget Sound water)

Edith, Nina, Willa, Sophie: Amount of light (Materials: 3 full-spectrum bulbs, 3 lamps, barnacles, Puget Sound water, glass containers)

Kiri, Nathan, Eleanor: Noise pollution level (Materials: barnacles, Puget Sound water, glass containers, laptop, YouTube video of a running boat engine, speakers)



Section 4:
Jonah, Ella, Gabby: Amount of food (Materials: 1 type of fish food, barnacles, glass containers, measuring spoons, Puget Sound water)

Leila, Alayna, Serenne: Amount of light (Materials: glass containers, barnacles, Puget Sound water, light, something to provide shade)

Finn, Addie, Matt, Nick: Concentration of silt (Materials: glass containers, barnacles, silt, Puget Sound water, pencil, paper)

Poppy, Kassie, Alex: pH level (Materials: pH buffers, pH strips, barnacles, glass containers Puget Sound water)

Francis, Julien, Quinn: Barnacle density (Materials: rocks with different barnacle densities, glass containers, Puget Sound water)

No assignment, but...

Please arrive to next Tuesday's class on time and be ready to go with your barnacle group--we will need the entire period to work!  I will have all of the materials you requested, as well as copies of the instructions your group created today in class.

Have a wonderful weekend!  Will I see any of you at the Arts Walk???

Assignment #6 (due 10.7)

Please complete the Practicing Experimental Design handout for tomorrow.  Do your best to answer the questions using the information provided.  If you aren't sure or feel as though you don't have enough info to provide a good answer, simply say so on the handout!  We will discuss tomorrow in class!

Also, be sure your barnacle group has the Independent Barnacle Investigation handout for continued work in class tomorrow.

No assignment, but...

...please rest from today's quiz AND remind your group "Paper Keeper" to bring the copy of the Independent Barnacle Investigation handout back to class tomorrow.

Quiz tomorrow, October 5th!

Continue preparing for tomorrow's quiz (October 5th) on microscopes, hypotheses, and variables. We will spend the first part of class reviewing; the quiz itself will take approximately 20 minutes to complete. Check out the review guide here!
