Quiz next Wednesday, October 5th!

Please begin preparing for the quiz on October 5th covering microscopes, hypotheses, and variables.  Check out the review guide here!  

Also, remember to bring your Let's Practice Organizing Data handouts from today back to class on 10.4.

No assignment tonight, but...

...be sure to bring your How to Construct a Data Table handout back to class tomorrow!

Assignment #5 (due 9.28)

Please complete the Quantitative or Qualitative? handout for tomorrow.  Reminder: Instructions are provided on the first page.  Remember to use your data notes from today for help!

No assignment tonight, but...

...please remember to bring your barnacle questions and hypotheses to class on 9.27.  Have an awesome weekend!

Assignment #4 (due 9.23)

Please record your 3 barnacle feeding questions from last night in the bottom of the table on your What is Hypothesis? (Part I) handout.  Then, convert each question into a hypothesis using the "If....then" format.  Finally, identify and underline the manipulated and responding variables for each hypothesis.

Give it your best shot...bring your work tomorrow...we'll discuss!!

Assignment #3 (due 9.22)

First, check out these 3 cool videos of barnacles feeding (click on the highlighted text). The first 2 are from last week; the last one is new:
This video shows barnacles feeding on bioluminescent (glow-in-the-dark) plankton.
This video shows a giant barnacle feeding up close.
This video shows barnacles feeding in breaking waves.

After watching the videos, create a list of at least 3 questions that come to mind about the environmental conditions which may affect the rate of barnacle feeding.  Think about where barnacles live and how they feed.  Consider when barnacles might need food and when they might not.  When you are finished with your list of questions, convert each question into a statement which begins with "I wonder how...".

Example:
Question: How does water temperature affect the rate of barnacle feeding? 
Statement: I wonder how water temperature might affect the rate of barnacle feeding.

Reminder: Bring your What is a Hypothesis? (Part 1) handouts to class tomorrow...

No assignment tonight, but...

...remember to bring your Microscopy 101 Diagram and Barnacle Lab Instructions to class tomorrow.

Also, please note that you should all have a 3-ring binder (or accordion folder) for science by now.  Please see T-Mac if you have any questions.

Assignment #2 (due 9.20)

Explain the difference between "magnification" and "resolution" when using a microscope.  You may find the information on this EXPLORING WITH MICROSCOPES webpage helpful as part of your research.  Also, be sure to bring your Microscopy 101 Diagram back to class on 9.20.

If you have time, check out these cool videos of barnacles feeding (click on the highlighted text):
This video shows barnacles feeding on bioluminescent (glow-in-the-dark) plankton.
This video shows a giant barnacle feeding up close.

Assignment #1 (due 9.14)

Find and record 5 cool, scientific facts about barnacles.  Remember to bring your Barnacle Lab Instructions to class tomorrow.  Explore this blog--bring your questions about how it works and suggestions for improvements to class tomorrow.
