                        1.  Quiz on triangles. Acute, Obtuse, and Right.
                        2.  Check on the classwork / homework:  Students were building cubes and tetrahedrons in class and were asked to calculate the volume and surface area for each. The assessment checked to be sure the work in their books was completed.

            B. Computer work day – Students had tome to begin lesson 14 on using “nets” to find surface area.

09.25.2019 – Math / Science / STEAM

WEDNESDAY

I.  Math:  Polygons / Prisms / Angles
         A.  Warm up / class work:  Students worked o making their own ACUTE, OBTUSE, and RIGHT triangles along with parallelograms and triangles that have a specific area. (Goal: When students create their own questions and answers they gain a deeper understanding of the subject matter.)

         B.  Notes:  Polygons.
                  1.  The difference between edges and vertices.
                  2.  The difference between exterior and interior angles.
                  3.  Naming angles.
                           i.)  … with one letter, showing the vertex.
                           ii)  … with three letters - the vertex as the middle letter.

         C.  Video clip (4 min) Platonic Solids – Prisms
         D.  Homework:  Complete the glossary on page 115 (Definitions) Attempt pages 112 – 114 – We’ll be reviewing those as a class tomorrow.

II.  Science:  Cells / Consumers / Producers
         A.  “The Martian”  - Mark Watney grows potatoes in Martian dirt; turning it into soil by adding bacteria. Plants will not grow in dirt. Soil contains fungi, protests, and bacteria – ALL essential for plants.
         B.  Plants are PRODUCERS. They do this amazing thing called PHOTOSYNTHESIS – Taking sunlight, carbon dioxide, and water and recombining the atoms to produce sugar. They cast off oxygen in the process; which is great for us animals for that whole “breathing” thing.
         C.  CONSUMERS (Animals) Eat producers or eat something that eats producers. Think about cows. They have the ability to digest plant grass directly (something we can’t do because we lack the necessary enzymes to break it down. Don’t worry – we’ll learn about enzymes in four weeks. Our focus is CONSUMERS, PRODUCERS, PLANT CELLS, and ANIMAL CELLS.

III.  STEAM
         A.  Flight Web Search #2:  We were going to fly our airplanes outside again today but it was 91 degrees Fahrenheit and completing our web search seemed good for today along with completing the last five minutes of the brief “Mythbusters” Episode on Helium Footballs.

         B.  The “Mythbusters” did an excellent job of illustrating VARIABLES in an experiment.

09.24.2019 - recap -

09.24.2019 – Tuesday –
Recap

I.  Math:  Polygons, Area, Surface Area.
            A.  Warm – up / class work:  Students worked on area questions where the area could be found by either decomposing the figure or using the area formula.  The sheet was composed of questions from a quiz we had last week and we wanted to check progress on understanding area.

            B.  Notes: We took the notes on an open page in our text.  The notes were on the edges and vertices of polygons. (See below.)

              C.  We went through the edges and vertices from the last homework. Tonight our goal is through 109 in our text.
           
II.  Science: Cell Organelles – Structure and function –
           
            A.  Current Events: Two notes on coal: 
                        1.  Coal is still the primary source of electricity in the world.
                        2.  Coal is a fossil fuel; meaning it comes from the remains of one-living things. By burning coal we add carbon to our atmosphere and increase the temperature of our biosphere. Coal and methane emissions drive global climate change.

            B.  Cell parts and function:
                        1.  Students had two “cut and pastes” for their notebooks.  We’ll return to “The Martian” in a bit. While students learn what the various parts of a cell do we are trying to build some context for the definitions – otherwise it is just rote memorization. For example – Proteins and vacuoles – Beyond color-in sheets students need to have an idea of the importance of these organelles. Otherwise it’s just remembering things to pass a test.  Our next test is an open note assessment this Friday.

III.  STEAM – Aeronautical Engineering –

            A. Today we flew our paper airplanes for distance, outside the classroom, and then returned to the class for a brief lesson on variables in an experiment.

I.      Math:  A brief quiz on area of triangles and parallelograms.
a. In-class assignments on finding the third interior angle of a triangle when the measure of the other two angles in known.

II.    Math Notes

a.     In all triangles the interior angles sum to 180 degrees.
b.     If a triangle has one angle in 90 degrees it is called a RIGHT triangle.
c.     If a triangle has all three angles less than 90 degrees in is an ACUTE triangle.
d.     If a triangle has an interior angle that is GREATER than 90 degrees it is a, OBTUSE triangle.

   III.  Math homework – Pages 98, 99, and 100.
            a.  Important – Students were given a multi-page math packet that is for class work. The focus is on perimeter and area. It’s not assigned as homework. It’s meant as supplemental classroom practice. Thanks.

   IV. Science: Open note test followed by seed observation and inquiry.

a.     Students were asked to speculate on and draw the seeds we grew in class.
b.     A brief clip of “The Martian” to highlight the difference between dirt and soil. Soil is composed of some non-living and some living material.
