Science

Welcome to 7th Grade Science!

We’ll be learning about the basics of chemistry and understanding chemistry in the environment. We will focus on critical analysis of information and present results from experiments that are carefully designed.

You’ll be expected to ask questions, think critically, collaborate with peers, and evaluate the validity of data.


What’s Happening in 7th Grade Science and Tech

In Science class, 7th graders have been busy creating profiles of their chosen energy source.  On March 8, we will have our Energy Source Speed Dating event where students explain their source of energy, including diagrams of energy conversion, fun facts, and pros and cons.  Their profile posters will have the following information:

  • Where does your Energy Source come from?
  • What is it made of/from?
  • How is the source gathered and refined for human use?
  • How is your Energy Source used? In power plants, cars, fireplaces, etc?
  • How is your Energy Source turned into power for humans to use?
  • What waste products are produced after using your energy source? If so, what are they and how harmful are they?
  • How expensive is the Energy Source?
  • Are there any harmful environmental impacts of your Energy Source? If so, what are they and how harmful are they?

In Tech class, we are starting to design our own web pages!  Students will be designing their pages to display their Pay It Forward content.  Here are the guidelines for the design:

Your final Pay It Forward website should have a minimum of the seven distinct pages detailed below.  Think of each of these pages as sections of a report.

  • Main page that summarizes your PIF issue
  • Background Information – Root causes, Impacts, and Solutions
  • Interview (transcript, notes, and/or main takeaways)
  • Stakeholder analysis
  • Poem
  • Action (lesson plan, essay with survey, or public service announcement)
  • Bibliography (using proper MLA formatting and hyperlinks)

The following elements should be on each of your web pages:

  • Title and your name (first names only!) that is styled to look the same across all pages
  • Navigation bar hyperlinked to all pages
  • At least one cited image on each page (other than Bibliography).  Note:  your images should be your own or be licensed for Creative Commons use
  • At least one hyperlink that is not part of the Navigation bar
  • At least one ordered list and one unordered list on your website (not on all pages)

Your CSS style page should have the following elements:

  • Consistent layout across your pages
  • Various font sizes across the headings and paragraphs
  • Borders (text and/or images)
  • Rules for one styling class

Energy Source Research Links

Below are many links to resources that should help you research your given Energy Source.  If, in your own research, you find additional links, please email these to me so that I can add them to this list!

Testing for Dissolved Oxygen

Currently in Science, we are testing the levels of dissolved oxygen in water from different sources, at different temperatures, and of different salinity.  We are learning about the Winkler Titration technique and its impact on aquatic life in Washington.IMG_7284 IMG_7283 IMG_7282 IMG_7281 IMG_7280 IMG_7279 IMG_7277 IMG_7276 IMG_7275 IMG_7274 IMG_7273 IMG_7271 IMG_7270
