Coastal Cleanup Data Indicates Cigarette Butts and Plastic Pieces are the Most Common Items

“This year, more than 7,000 volunteers removed nearly 10,500 pounds of debris from coastal areas, capturing it before it could pollute the ocean. More alarming than the unusual items, says cleanup organizers, is that volunteers removed nearly 207,800 pieces of trash including more than 75,000 cigarette butts, 23,500 plastic pieces and 17,500 bits of plastic foam (the top three items removed).” – excerpt from press release by Surfrider Foundation’s San Diego County Chapter.

  • Describe the mission of the New England Aquarium and how it is conveyed throughout the exhibits

NEAQ4

  • Share experiences from the touch tank and the giant ocean tank

NEAQ3

Normal criteria for a blog post apply:

  • 150 words
  • pictures (if they are not yours, provide a citation!)
  • links to additional information (at a minimum, provide a link to the New England Aquarium, but other links could take readers to additional information on particular animals, such as penguins)
  • provide appropriate keywords on your post
  • publish and share the link

 

Pizza-Bread-2Below you will see labels for several products commonly used in daily life. In groups of two, using only a periodic table, locate fifteen compounds in the given products of which you can determine the chemical formula. Write what product(s) it is found in (if found in multiple products list all), and the chemical name in the ingredients list on the package. Determine the chemical formula and whether it is an ionic or covalent compound. Some compounds will be written in an improper chemical way, please correct the name if needed. You must find at least one acid and covalent compound.

Scoring: 1 point for every correct formula and classification; +1 for every corrected name

Plate Tectonics and the Seafloor

The people who first mapped the seafloor were aboard military vessels during World War II, using echo sounders  to search for submarines. The results produced a map of seafloor depths. Depth sounding continued after the war. Scientists used this information to produce bathymetric maps of the seafloor. During WWII and in the decade or so later, echo sounders had only one beam, so they just returned a line showing the depth beneath the ship. Later echo sounders sent out multiple beams and could create a bathymetric map of the seafloor below. Using the resources provided, answer the following questions, in complete sentences, on your blog. You may copy and paste these questions and resources, to get you started.

How We Blog

A blog isn’t about being a blog, rather it is a means for communicating ideas, much as a magazine does. A blog “post”, or article, may be:

  • Responding to and commenting on curriculum topics as we study them
  • Creating written projects/ media projects and commenting on each other’s work
  • Reflecting on coursework and individual learning
  • Reviewing and sharing study strategies before tests and quizzes
  • Practicing taking varied points of view on a topic
  • Discussing current events
  • Making classroom suggestions
  • Creating FAQ pages on curriculum topics

That being said, here are some practical suggestions:

Headings are useful. Things like:

  • Objective
  • Introduction
  • Experimental Results 
  • Conclusion and Analysis
  1. Don’t number things that don’t need to be numbered. Write the procedure as a paragraph. List materials with bullets. Answer questions as stand-alone text.

Use pictures. Cite them. Remember that they must be uploaded – do not copy and paste.

Eyes

Don’t tire me out.

Use white space. One long paragraph in Times New Roman can tire the eyes. Make logical breaks.

Mollusk Analysis

Molluscs, Mollusks, Mollusca

Make your learning a conversation with others!  You have watched the video on mollusks. You have taken notes from the lecture. And you have dissected both a clam and a squid.  Now you must take the information and your studies of the mollusks and write an analysis, a conversation of what you learned. This analysis must be posted on your marine biology blog.

Write your analysis as a discussion or a story. Please do NOT write your analysis as a list of answered questions, even though you have been given a list of questions. The questions below are meant as a GUIDE for your discussion. Insert the answers into a story of your investigation into the world of mollusks.

You will be assessed on 1) knowledge of the subject material; 2) describing the material in your own words and in an interesting manner; and 3) personal contribution to the topic. And please provide illustrations, with citations.

Adaptation and Variation in Mollusks

  • What is the morphological feature of molluscs after which the phylum is named?
  • What are the biological troubles that molluscs face due to their soft body?
  • Into which classes are mollusc divided? What are some representing beings of each class?
  • Is there any body symmetry in the animals you dissected? Describe it.
  • Describe your notes about any textures, shapes and other observable qualities in the animals you dissected.
  • What is the function of the clam’s mantle?
  • How does the locomotion of the squid and clam compare?
  • Why do you think the squid and the octopus have camouflage, whereas the bivalves and gastropods do not?
  • Compare the feeding methods of bivalves and gastropods. Of bivalves and cephalopods.
  • What organs are present in both human and mollusc bodies?
  • Describe the special adaptation that mussels have for surviving strong wave action along the shore.
  • Why is the octopus considered to be so intelligent?
  • What are examples of the ecological and economic importance of molluscs?

Be thorough and complete.

Gas Law Analysis

The purpose of the labs was to determine how pressure, temperature, and volume were related in a gas.

Make your learning a conversation with others!  You have watched demonstrations, read txt, practiced gas law equations, and done some labs. Now you must take all this learning and write an analysis, a conversation of what you learned. This analysis must be posted on your chemistry blog.

Write your analysis as a discussion or a story. Please do NOT write your analysis as a list of answered questions, even though you have been given a list of questions.  You will be assessed on 1) knowledge of the subject material; 2) describing the material in your own words and in an interesting manner; and 3) personal contribution to the topic.

Labs you have done related to the gas laws are:

Hot Balloon:  An Erlenmyer flask with approximately 50 mL of water in it and a balloon secured on top is heated, and the circumference of the balloon is measured before and after heating the water.

Cartesian Diver: A 2-liter soda bottle is filled with water and a medicine dropper placed inside. After being capped, the bottle is squeezed.

Soda Can Crush:  A soda can with a small amount of water in the bottom was heated on a hot plate, and then flipped with tongs into ice water.

Pressurized Balloon:  A 2-liter soda bottle that has a balloon inside was pressurized.

Pressure and a Bag:  Two large jars with plastic bags taped over the mouths, one inside and the other outside.

Demonstrations you have seen related to the gas laws include the Bell jar vacuum. Individually, the following were exposed to a vacuum under the bell jar:  glass of water, balloon, marshmallow, shaving cream, empty water bottle.  You also saw the press of air against an evacuated metal sphere with handles.
