Math AIR tests are periods 1-4 on Monday and Tuesday. If you are missing science class, please watch the following videos by class time on Wednesday 4/26 and complete the 3-2-1 video guide.
Welcome back from break!
We begin the week with a look at types of energy and an activity on Elastic Potential Energy. We will be on the floor on Wednesday, dress appropriately!
The Law of Conservation of Energy:
Elastic Potential Energy…fun stuff!
On to magnetism…a favorite!
We have so much going on this week…hold onto your hats…
- Monday-ELA testing, day #2
- Tuesday-All free body practice diagrams due AYE
- Wednesday-Motion and Forces Summative; gravity
- Thursday-Concept Reviews due AYE; gravity
- Friday-gravity; enjoy spring break, see you on april 18th
So what is gravity?
How about a ride in the Vomit Comet?
What? How can they hit the ground at the same time?
Astronauts tested out the ideas about gravity on the Moon.
We can do this on Earth, if we create a vacuum.

So we all know that gravity acts vertically, did you know it also acts horizontally, between objects?
Let’s check out this PHet simulation.
How do mass and weight differ? What would your “mass” weigh on other celestial objects?
Let’s try this out and see. Exploratorium
A last look at gravity from two perspectives:
This week, we move onto forces and free body diagrams.
Free–body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation.
Continue to check the weekly agenda. Between field trips and testing dates, there are lots of things to keep track of.
Notice: First physics assessment is on Wednesday, April 5th.
We have switched our focus to physics, our final unit of the year.
You should be working to learn the 36 new vocabulary words. There are no assignments related to the words, but we will have quizzes and the words will be used in class. The more familiar you become with them, the better. (See class resources in the menu bar for the Quizlet link)
We are wrapping up 3rd quarter and our study of life science. We will turn our attention to the final unit of the year, physics.
With snow days on Tuesday and Wednesday, there have to be some adjustments to the schedule.
- Life Science test in on Thursday.
- Grades are due by noon on Friday so the 3rd quarter notebook check will not make it onto 3rd quarter grades. Therefore, we will hold off and do the notebook check on Monday.
- Friday-Meet in the Betty Patton Room
We won’t have time to watch this Cosmos episode, but if the mood strikes you…it is good!
You have been given many options for vocabulary study this year. For the final 36 vocabulary terms, choose a way to work and study with the terms that is best for you.
BREAKING NEWS-due to the unexpected day off, our schedule for the week will be pushed one day. Rock Pocket Mouse should be done and ready to discuss on Friday. Bring devices for KAHOOT. Test will be Tuesday and notebook check on Wednesday.
This week’s focus is on Darwin and the ideas of Natural Selection.
We have a busy week with a vocab/notecard check, vocabulary quiz, Rock Pocket Mouse activity, and a Life Science Summative.
Try this Modes of Selection simulation. This is a flash type file and seems to work inconsistently on devices.
Here is another link that gives some more background.
This is the last week of the quarter and the notebook table of contents will go out mid-week for a check next Tuesday.

Watch for big ideas here…
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.
Up next-Darwin and his ideas
BIG IDEAS FOR THE WEEK:
- When two heterozygous parents are crossed, the resulting offspring’s phenotypes show the dominant trait three times more than the recessive trait.
- What traits are advantageous to the continuation of a species? We will investigate.
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.
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)
This week we start to exploring Unit 6-Reproduction, Genetics, and Heredity
Reproduction-Asexual vs. Sexual
Click here for a good summary of mitosis vs. meiosis
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.
This week we transition from Earth Science to Life Science.
Monday-Geologic Time Summative
Tuesday-Vocabulary BINGO cards needed for review
Wednesday-Post-test for Earth Science Vocabulary
Thursday-Introduction to Drosophila Melanogaster
Friday-Life Science Introduction and vocabulary
Snow Day-round 2-the Weekly agenda has been updated in Google classroom
Vocabulary quiz will be Thursday of this week, the Geologic Time summative will be next Monday, and the summative over Earth Science vocabulary will be the next Wednesday.
Absolute Dating/Radiometric Dating
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’s Topics
Fossil Evidence for Climate Change
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.
Now an introduction to the activity…click on the image.
Follow up video:
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.
Quarter 3-Week 3
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.
