WEEKEND HOMEWORK

Hi everyone,

In class today we reviewed cell parts. If you missed it I will be uploading those review sheets but they're super important because we will be taking a test on that material. We also took a test today so if you've been absent you should ask Jesse about that.

The homework this (long) weekend is to annotate a new reading that was assigned today and to study for the test coming up.

Have a great weekend everyone.

September 17

Hey everyone,

today we were given work time to complete a checklist with various tasks including:

• Completing/writing a reflection on experiments
• Creating flash cards with vocab from science content 
• Annotating "Cell Reading" and writing PD

If you missed today you can get started on the above tasks but make sure to get the checklist from Jesse because you will have to turn it in. We also had meetings that will be crucial to your project so make sure you can get that squared away. 

September 12th

Today in class most of us completed our experiments. We also wrote paragraphs about our scientific phenomena. While I am taking notes for biology, there is a lot of overlap between the biology and engineering assignments. Major goals for the Engineering Biology Project include:

• figuring out what your museum exhibit will look like
• understanding the related science
• creating a rough sketch of your exhibit 
• updating your website to include your most recent experiment

September 10th

Today in class we worked on revising and updating our protocols. If you sent your protocol to Jesse or Mackenzie they will have left you notes on how to improve it.

Some important things to remember when planning scientific experiments:

• Science usually prefers quantitative data (numbers) over qualitative data (words)
• Always create a control (a test group not subject to the variable being tested) to ensure accuracy

I haven't had a scanner but now that I do, here is the Molecules of Life worksheet. 

Weekend Materials

Hey Everyone,

I just wanted to remind you that you will need the materials  for your lab on monday.

September 6th 2012

Today in class we reviewed the types of inquiry as seen in museum exhibits. We also wrote journal entries about the exhibits we enjoyed.

After this warm up we broke up into groups and discussed our scientific experiments. Every individual had to create their own google doc protocall describing their experiment. Post it and share it with Jesse and Mackenzie. This experiment is not the same as your exhibit. Mine looked like this:


Question: What type of plant material produces the most electricity?

1. Remove surface skin from melon. Attach zinc wire and copper wire to voltmeter using 2 alligator clips. attach copper and zinc wire ends to melon and begin timer.

2. Record electric output every 30 seconds (starting at 0) until output stops. Record total time producing electricity.

3. Repeat  step 1 and 2 with sweet potato.

4. Repeat  step 1 and 2  with pineapple

5. Repeat  step 1 and 2  with apple.

6. Repeat  step 1 and 2  with lemon.

7. Repeat  step 1 and 2  with grapefruits

8. Repeat  step 1 and 2  with kiwi

9. Repeat  step 1 and 2 with oranges

10. Repeat  step 1 and 2 with  tangerines

11. Solve for total electricity produced for different plants.

Materials

• Melon
• Sweet potato
• Pineapple
• Apple
• Lemon
• Grapefruit
• Kiwi
• Oranges
• Tangerines
• Zinc wire
• Copper wire
• Alligator clips
• Voltmeter

Hey everyone!

Today in class we began by finishing up our 2 journal entries from last week.

Each entry included

• 1 explanation of a biological phenomena 
• a cited source 
• a clear plan for an experiment
• 2 definitions of key terms

We also did a grouping exercise (if you missed it you need to talk to Mackenzie). 

Deadlines:

Tomorrow is a field trip so pack a lunch and $5. Also, begin reading and annotating your cell reading, this will be due on monday (up to page 18).

Thursday August 30th

Today in class we warmed up with a review of macro "big" molecules.

Here are some key notes from today and yesterday.

The 4 main types of macro molecules are:

1. Lipids
2. Carbohydrates
3. Proteins
4. Nucleic Acid

Poly means many

Mono means one

• Mono means one
• Poly means many
• Monomers are small molecules that bond to create polymers 
• They bond through a dehydration reaction (think removal of H20) 

Sucrose is a polymer made from the 2 monomers glucose, and fructose. A starch is a polymer made up of 3 or more glucose monomers.

Next is a list of the monomer types for each of the for macro-molecule types:

Lipids--Glycerol and Fatty Acids

Carbohydrates--Sacharides

Nucleic Acid--Nucleotides

Protein--Amino Acids

A peptide bond is the form of bond used to create a protein. 

HW: Update DP, Read/Annotate Biology 101 Reading, write PD
