Science Assessment

04.03.2020 - Friday - (Email me a typed response or scan your hand-written responses. Due 04.10.2020 - Friday - )

Complete the following outline on the four (4) cycles we’ve studied.  The first one (THE ROCK CYCLE) is done for you. Write a brief description of;

1. The major steps in the cycle.
2. How the cycle is important for life.
3. How the cycle interacts with ONE other cycle.

1. ROCK CYCLE:
1. The rock cycle begins when lava or magma cools to for igneous rock.  Igneous rock can me broken down to make sedimentary rock, or it can be put under heat and pressure to form metamorphic rock. Sedimentary rock can become metamorphic as well.  Both sedimentary and metamorphic rock eventually get pushed down into the mantle on Earth to begin the cycle again.
2. Life depends on the rock cycle for land, for recycling minerals and chemicals necessary for life, and for releasing gasses and material into our atmosphere that life depends on.
3. Part of the rock cycle depends upon the water cycle because rain, ice, and snow help break down hard rock into smaller sediments.

04.03.2020 - Science Notes and Assignment for Friday -

04.03.2020 - Friday - Science Notes (left side)

(Remember to - as always - define CAPITALIZED terms.)

1. Current Events:  CNN 10 - 
1. One note on what is NOT down about this corona virus.
2. One note on the Arabian Desert. (This is a perfect tie in when we study the rain forest! There’s an interesting connection between the rain forest and the desert.)

II.  Seed plants and flowers:  Chances are that today’ll you’ll enjoy several items of food brought to you by SEED PLANTS.

A.  There are more than 300,000 plant SPECIES!

B.  All plants are made of EUKARYOTIC cells.

C.  The building you are in, right now, is likely being held up by plants! Well, kind of. Think about wood. Wood is made from trees and it has its characteristic hardness from CELLULOSE … the cell walls left over after the plant cells are no longer living.

III.  We’ve spent some time talking about that incredible CHEMICAL REACTION, PHOTOSYNTHESIS - the chemical reaction that takes water and carbon dioxide and makes sugar while releasing oxygen in a form animals can breath. The PHOTOSYNTHESIS takes place in an ORGANELLE called CHLOROPLASTS.  

IV.  Most plants SPROUT from a SEED. 

A.  A SEED (the subject of our next observation / drawing) is, basically, and undeveloped plant in a hard shell that protects it from drying out and , often, provides food for the SEEDLING.  

B. SEED PLANTS are responsible for the FRUIT and vegetables that you’re eating today.

V.  Remember the video and notes on celery stalks? All seen plants are VASCULAR, they have specialized structures to carry food and water.

VI.  ROOTS absorb the water and nutrients and bring it to the STEM.  

A.  XYLEM: Carries water, sap, and minerals through a plant.

B.. PHLOEM:  Carries food (sugar, AMINO ACIDS ,and nutrients.

V. Plants are characterized by how they reproduce.

A.  ANGIOSPERMS:  The seeds are located inside a FLOWER  

1.  Product fruit after the seeds are POLLINATED.

2.  Most plants in land are angiosperms. There are two classes of angiosperms.

i.) MONOCOTS (One seed leaf.)

II.) DICOTS (Two seed leaves.)

B. GYMNOSPERMS:  

1.  Produce no fruit.

2.  Usually have CONES to reproduce. (Remember our walk around campus when we observed conifers and saw the pollen collecting on surfaces?)

V.  Assignment for the right side of today’s notes. Define the CAPITALIZED terms and write their definitions - along with a quick sketch (if possible.)

0403.2020 - Daily Note - Friday - 

1. Good Morning - There’s a class code for STEM added below and the science reflection/quiz is going up to the blog and Google Classroom. 
1. There will be no online lessons posted by teachers on the Spring Break week.

II.  The link for attendance: 

A.   https://docs.google.com/forms/d/e/1FAIpQLSd2s0AMvXbAXE6xWIZKc8KuCFL6NkeIZbTxub5lnN4FjZ5B-Q/viewform

III.  The science reflection / quiz will focus on the interplay between the four cycles we’ve studied. 

A.  The science assignment is based on yesterday’s notes; with defining the CAPITALIZED terms and drawing a flower. We’ll identify the parts of a flower and review how traits are mixed and passed along.

B.  CNN 10 link for current events ….   https://www.cnn.com/cnn10

IV.  Google classroom links.

A. The Google Classroom links:

    1.  Math.      o5jdv6r

    2.  Science.     xxhaswm

    3.  STEM:  yox77qa

V.  Kahn Academy log in code:

A.  The Kahn Academy class code for math:  77R2HNBX   

VI.  Have a great weekend and look for the flower update in the science notes as well as one more Kahn Academy update for math.

04.02.2020 – Thursday – Science Notes

(Left side of notebook – remember to look up, and write, the definitions of any CAPITALIZED words.)

I.  Current Events:  Two (2) please from today’s CNN 10 on the virus and/or masks.

         A…

         B…

II.  Tomorrow’s email assessment:  You are asked to write about the four cycles we’ve studied and how they interact and provide an environment for life here on Earth. The questions will be posted by 9:00 am Friday, 4/3.

III.  Reproduction on land:  When PHOTOSYNTHESIZING organisms adapted to life on land, obtaining water was not the only challenge they had to overcome. Reproduction strategies changed as well. Reproduction can happen in two ways.

         A.  Sexual reproduction.

                  1.  Involves GAMETES.

                  2.  MEIOSIS

                           i) FERTILIZATION

         B.  Asexual reproduction

                  1.  There’s no fusion (joining) of GAMETES.

                  2.  Usually, in asexual reproduction, the plant makes an exact copy of itself. Basically, a clone. Sometimes, however, there may be a MUTATION.

         C.  Current events tie-in:  When MUTATIONS occur in a corona virus, the virus might gain the ability to infect people, or other animals, more efficiently – as COVID 19 apparently has.

IV.  FLOWERING PLANTS – These are the DOMINANT plant form on land.

         A.  FLOWERS:  Produce male and female GAMETES.

         B.  POLLINATION: Occurs when the GAMETES combine.

V.  When organisms were surrounded by water – before life adapted to land – gametes could easily combine in liquid water without concern for drying out and traveling from place to place.  Now that there are land plants … I want you to think about at least two (2) ways GAMETES can “meet” on land. 

         A….

04.02.2020 – Thursday –

     Good morning. In math some more Kahn Academy has been assigned along with the unit 6 work. Yesterday’s science notes were posted on the blog and in Google classroom, focusing on the Nitrogen Cycle. Students were asked to sketch the cycle themselves for the right side of the notes and tomorrow’s assessment will be about the four cycles we’ve talked about. (Nitrogen, Carbon, Water, and Rock.) I’ll post a sketch for the right side of yesterday’s notes as well.

     My goal today is to work on week-long packets and move beyond the day-to-day assignments.

     I hope everyone is doing well. I received some wonderful tree sketches and rock cycle descriptions. I’ll try to improve the quality of those wonderful YouTube videos J …. OK, there’s, probably, no chance I’ll make a living as a “YouTuber;” but I do hope the video clips help[ with a quick review of where we’ve been and where we’re going in science. – Thanks

(left side of today's science notes. For the right side, sketch the Nitrogen Cycle! I'll put up my sketch of it later but I would like you to challenge yourself to draw the cycle, using arrows to show how Nitrogen travels through our ECOSYSTEM.)

Nitrogen Cycle notes – Remember to define CAPITALIZED words J

I.    Current events and the nitrogen cycle.

a.     The current pandemic is caused by a virus. All viruses are strands of DNA or RNA (genetic code) surrounded by a protein “coat.” (capsid.)

b.    Nitrogen plays and important role in both the structure of PROTEIN and DNA and RNA.

II. When we take a breath at sea level only about 21 percent of that breath is oxygen.  More than three-fourths of that breath is nitrogen gas.

a.     Nitrogen gas, in our atmosphere, is generally INERT and we breathe it in and out but it can’t be absorbed by our lungs and used by our body in the form it is in while it’s in our atmosphere.

III.      Rain and snow bring nitrogen to the SOIL and certain kinds of bacteria that live in SYMBIOSIS with plant roots break apart the nitrogen MOLECULE and recombine it with hydrogen.

a.     Remember our analogy of atoms to “Legos?” Atoms (individual Lego) can be combined and recombined to make all kinds of COMPOUNDS. From two hydrogen, and one oxygen, atom combining to make a WATER MOLECULE, to Carbon, Hydrogen, Nitrogen, and Oxygen (along with some other types of atoms) linking in very long chains to make DNA and RNA or PROTEINS.

IV.         Plants use the nitrogen compounds and animals are able to get these nitrogen compounds into their bodies – in a form they can now use – by eating plants or other animals.

V.    When animals get rid of waste, or die and decompose, the nitrogen is returned to the soil where plants can use it again (thanks to bacteria) or it’s released to the atmosphere to complete the cycle.
