Week of February 27 to March 3, 2017

This week we will be working with “Mendel’s Magic Ratio” by looking at our smiley faces and the fruit flies. We will wrap up genetics and heredity with a look at pedigrees.

Biography

BIG IDEAS FOR THE WEEK:

  • When two heterozygous parents are crossed, the resulting offspring show the dominant trait three times more than the recessive trait.
  • What traits are advantageous to the continuation of a species? We will investigate.

Week of February 20, 2017

During this four day week, we will continue to investigate heredity and genetics with some in class activities. We are also eagerly awaiting the arrival of the F2 generation of Drosophila Melanogaster.

Video Recap

Our big ideas for the week are:

  • Focusing on using the vocabulary for genetics and heredity
  • Monohybrid genetic crosses (P1 through F2)
  • Seeing the importance of the genetic variation that is a result of meiosis and fertilization (sexual reproduction)

 

Week of February 13, 2017

This week we start to exploring Unit 6-Reproduction, Genetics, and Heredity

Reproduction-Asexual vs. Sexual

Genetics-the study of heredity and the variation of inherited characteristics

BIG IDEAS OF THE WEEK

  • The purpose of reproduction is to continue a species.
  • Asexual reproduction results in exact copies of the parents.
  • Sexual reproduction introduces variation into a species.
  • The variations are called traits and they are expressed on your chromosomes as your genotype.
  • The traits are expressed as your phenotype.
  • Gregor Mendel was an Austrian monk that studied the variation of pea plants.
  • A Punnet Square is useful in determining genotype and later phenotype.

Quiz and Summative Prep

Geologic Time vocabulary quiz is on Thursday-go to Quizlet to prepare.

What should you study for the Geologic Time summative on Monday?

Text Book Pages-110 to 116, 117 to 121, 123 to 125, 127 to 129 and 138-141.

All activities and posted answer keys (when applicable):

  • Geologic Time webquest
  • Geologic Ticker Tape Timeline
  • PETM Activity
  • Relative Time Activity and Practice
  • Absolute and Radiometric Dating Activity

Next Wednesday will be our summative over Earth Science vocabulary. You will have BINGO cards to work on all week and you can use Quizlet or your vocabulary cards to prepare.

This week we will do an activity using leaf fossils to look back in time at climate change. Click on the video below for the introduction to the ideas we will be studying.

Relative Dating

Big ideas for the week:

  • The geologic processes that have shaped our planet in the past are still at work today.
  • Rocks are organized in layers, much like layers of dirty clothes in a clothes hamper.
  • Relative dating of rocks tells us which rocks are older and which are younger.

Week of January 16th, 2017

Quarter 3-Week 3

Geologic Time

Big, bright ideas for the week:

  • The earth has been around for a long time!
  • For a lot of that time, the earth was forming into a planet that could sustain life.
  • Early life forms were single-celled.
  • There have been a few mass extinctions that have wiped out large numbers of living things.
  • We know about life before us by looking at fossils and the record left in rocks.
  • Humans have been around for a short period of Earth’s history, but we use the clues left behind to see how the earth has changed and how we fit.

Week of January 9, 2017

Welcome to the 2nd week of the 3rd quarter!

We will continue our study of erosion and deposition. See the weekly agenda in Google Classroom for daily activities and assignments.

Check out the Google Calendar in the menu bar for posts about upcoming assessments.

Big Ideas for the week:

  • You should be able to discuss how erosion and deposition in moving water work together to change the features of the earth.
  • You should be able to identify erosion, deposition, a point bar, a cut bank, a meander, and a delta within the stream tables.

We will have an assessment on Thursday and move on to our final unit of Earth Science-Geologic Time, later in the week.

Week of January 2nd, 2017

Image result for happy new year

Welcome back to a new year and a new semester.

We are changing how posts are done on the website.

From this point forward a general post with the main ideas of the week will post on Monday mornings. The specifics of each day, including copies of notes, keys, and assessments will be posted in Google Classroom.

The website will still have all reference material and any sites that we use attached, but a streamlining of procedures was necessary for time management purposes.

The Big Ideas in science this week:

  • Erosion is the movement of weathered sediments and particles.
  • Deposition is the putting down of the eroded materials in a new location

Without erosion, there is no deposition.

  • How did the variables of volume or slope influence the size of the delta that was created in the stream table?
  • We will be using an app called LAPSE IT to do some time-lapse videotaping of our stream table investigation. During the investigation you will relate the size of the delta from day 1 to the size of the delta on day 2, after changing either the slope of the stream table or the volume of water in your “stream.”
  • You will work to make observations, gather data, and draw conclusions.

Week of December 12-16, 2016
