Begin Unit 8: Natural Selection (All Quick Checks This Week!)
This week we will dive into the world of natural selection and talk about how organisms will change over time due to the environment that they live in. We will watch videos, play a GimKit, create a one pager on a whiteboard, as well as simulate how animals would hunt and cause natural selection to take place. Words to think about this week:
adaptations inherited traits selective breeding genotype and phenotype genetic variations survival probability of survival |
Finish Unit 7: Classification and Start Unit 8: Natural Selection
We only have one more unit to go after this! On Monday, we will use time in class to work on our Sample Work. There are three parts to this assignment. Begin the assignment by comparing two animals with similar physical characteristics. For example, a wolf and a dog are similar but are put into different species groups because of their characteristics. Second, we will sort and classify our favorite snacks and practice dichotomous keys. And last, we will research an animal and label all the levels of taxonomy of that animal! Once you finish the sample work, you are ready for the test!
Utah SEED Content Standard 8.3.3
Ask questions to obtain, evaluate, and communicate information about how changes to an ecosystem affect the stability of cycling matter and the flow of energy among living and nonliving parts of an ecosystem. Emphasize describing the cycling of matter and flow of energy through the carbon cycle. (LS2.B, LS2.C)

Unit 7: Classification Introduction Week (Quick Checks)
This week we are studying our Classification Unit. Scientists classify organisms in an organized manner. They sort things by physical characteristics. Dichotomous keys are used as a two question process used to help classify an organism. We are going to practice how to make dichotomous keys, how we compare and contrast organisms, and also how to sort and classify non living things.
Here is a website to check out to practice using dichotomous keys:

Unit 6: Cell Work Sample Work and Cell Work Test (Due April 25th)
This week we will finish up Unit 6: Cell Work. On Monday, we will work on our Cell Work Sample Work. You will need to draw a diagram of a chloroplast and mitochondria. If you use this website, it gives a lot of information on comparing the two important parts of a cell:
Also, here is a copy of the Cell Sample Work instructions needed for the project:
Utah Seed Standards: Standard 8.3.1 Plan and conduct an investigation and use the evidence to construct an explanation of how photosynthetic organisms use energy to transform matter. Emphasize molecular and energy transformations during photosynthesis. (PS3.D, LS1.C)
Standard 8.3.2 Develop a model to describe how food is changed through chemical reactions to form new molecules that support growth and/or release energy as matter cycles through an organism. Emphasis is on describing that during cellular respiration molecules are broken apart and rearranged into new molecules, and that this process releases energy. (PS3.D, LS1.C)

April 15-19 Mrs. Barrow Out For Testing!
I will be out for testing this week so I am asking for you to listen to the instructions below and participate in the Near Pod Sessions. THERE WILL NOT BE LIVE LESSONS THIS WEEK. On Monday, I would like for you to finish the Photosynthesis Portfolio we worked on in Live Lesson on Wednesday 4/10. Don't forget the three parts to the assignment: diagram, lab report, and summary. On Wednesday, after completing the Near Pod, please start working on the Cell Work Sample Work. This assignment involves three diagrams that are discussed in the Lesson Intro Page. THERE WILL BE NO IN AND OUT THIS WEEK! I will be available for webmail and voice mails if needed and feel free to book me for the following week, if needed.
Unit 6: Cell Work (Portfolio Due April 12th)
There are three parts to the portfolio for this unit. The first part (8 points), you need to be able to diagram and explain to me the whole process of photosynthesis and how plants exchange gases (visually). The second part is the beginning of a lab report. You need to come up with an experiment to PROVE that plants release oxygen. You need to write down a lab report explaining the whole process. Here is a link to a gizmo you can use:
When you are done experimenting, you need to write your results (10 points). After showing the results, you need to write a summary in three to five sentences explaining how plants are able to exchange gases and what you learned from this unit (10 points). Be sure to include what variables (what is being tested) we need to perform an experiment and prove that plants give us oxygen!

Unit 5: The Design World (Sample Work and Test due April 4th)
This week we will work on our Design World Sample Work and finish off Unit 4 by taking The Design World Unit Test. On April 3rd, we will play a review game that will review content for the upcoming test to see if you are ready or if you need that review to do well on the test. Remember to use the engineering process when thinking of how you would design a building, an electrical circuit, or even a chemical experiment. You always repeat the experiment using the scientific process.
When working on your sample work, I would love to see a list of materials with high conductivity, good insulation, strong enough to withstand gravity, strong enough to repel water and withstand oxidation (rusting), and many other materials that scientists and builders use in the real world. Take a look at the slideshow below to see what I am looking for:

Introduction to Design Unit (Sample Work Due April 1st)
During Live Lesson, we talked about the engineering process and how we use it daily with problem solving skills. Even something as simple as a phone not charging, we have to use our brains to design a plan to fix that problem. During this unit we will investigate electricity, gravity, heat and chemicals and how they are important to the design process.
Here is a PHET Simulation to work on if you want to review how an electrical circuit works:
https://phet.colorado.edu/en/simulations/circuit-construction-kit-dc
We discussed how sometimes the design process will not go as planned and you have to keep repeating the engineering process. Take a look at this experiment where You Tuber Mark Rober tries to drop an egg from space. How does this experiment involve the engineering process?

We also went over how a battery works along with a car engine. Here is a video of how a car engine works:
Efficiency and Machines (Sample Work Due March 12th)
Things to Remember:
1. Work Output / Work Input x 100 = Percent Efficiency
2. Efficiency= the ratio of the useful work performed by a machine.
3. In order to pass the SAMPLE WORK: You will need the mind map (see example to the left) AND a simple machine drawing with an explanation of how it makes work easier.
4. In order to complete an essay question on tests or assignments, you want to make a CLAIM, then give your REASON, and then provide EVIDENCE.

Force and Work (Simple Machines)
Unit 4.1, 4.2, 4.3, and 4.4 Lessons Due By March 6th
This week we are discussing what defines " work" in science. Work has to have a FORCE and DIRECTION of the force.
Force x Direction = Work (Joules)
Force x Direction = Work (Joules)
Simple machines help to make WORK easier. There are six main types of simple machines. We are going to focus on: levers, pulleys, and inclined planes.
