**Science: Mrs.Gnojewski**

*Learning Target: Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons.*

Students have been working on deepening their understanding of the causes of seasonal and daily cycles. Click here for a link to a great animation showing Earth's position during different seasons. We analyzed this video in class in order to better understand the role the angle of sunlight plays in variations in seasonal temperature and hours of daylight. On Tuesday, September 9th students will be demonstrating their understanding of seasonal and night/day cycles on a summative assessment.

**Humanities: Mrs. Axtman**

__Learning Target__: Explain the rise of human civilization, trace how natural resources and technological advances have shaped human civilization, build an understanding of the cultural and social development of human civilization, and identify the role of religion in the development of human civilization as it relates to Ancient Greece and Rome.

Students have been working on various learning stations to learn the history of Ancient Greece-these stations include topics such as "The Persian Wars", "Geography of Ancient Greece", "Myths", "Theater", and "Architecture" among others. This musical group also wowed me and each other with their excitement over putting on a musical parody based on one of the Ancient Greek myths,

*Theseus and the Minotaur*. I am still working on details for a performance, but for now mark your calendars for the evening of September 25th!

Students first notebook check is this weekend, and on Tuesday (after our Olympic Day on Monday) we will dive into Ancient Rome!

**Rational Numbers**

As we start the year students were taking a look at what are rational numbers. Students will continue adding, subtracting, multiplying, and dividing positive and negative numbers when solving a real world situation using models and creating equations to solve. They will also continue to make the comparison between rational and irrational numbers. Students began to express equations by combining and reducing like terms with integer exponents using exponent properties. Students looked at using negative exponent properties to simplify equations. They will also be able to use the square and cube root operation to solve simple equations. Scientific notation will be understood and used to notate very large and very small quantities. Students will then perform operations on numbers expressed in scientific notation.

__Students applied the distributive property of multiplication over addition to allow them to solve equations with parentheses. They also practiced using scientific notation. Scientific notation is a representation of very small or very large numbers. An example would be the distance between the Earth and the Sun is about 150,000,000 km and the mass of a dust particle is about 0.000000000763 kg. Instead of writing those numbers with many trailing or leading zeros, students can write: 1.5 x 102 or 7.63 x 10-10. A great tutorial if you have questions:__

__Students were able to use symbols to represent numbers. Algebra can be considered an extension of arithmetic. Students used exponential notation and variables to notate their equations created from real-world situations. Students then replaced each variable with its value to find the actual value of an algebraic expression.

**Period 2:**__Students practiced using the order of operations on integers to evaluate equations. Students were able to differentiate between like terms and unlike terms. When they did this they were simplifying equations. Students also practiced adding, subtracting, multiplying, and dividing rational numbers.

**Period 3:****Design with Ms. Newstadt**

Artists have been working with various Elements of Design including line, shape, form, space, texture, and value in class. After experimenting with various shading techniques including hatching, cross-hatching, stippling,and blending, students drew and shaded 2D circles (shapes) as 3D spheres (forms) concentrating on their blending technique. They first used a compass to draw circles, creating an interesting design using only one shape (filling the entire page with circles of various sizes, often overlapping and/or running off the edge of the paper). After choosing a light source, students shaded the circles with pencil and stomps using graded value, going from light to dark away from the light to make the circles look 3D before mounting the final piece of artwork on large black paper.

**Health and Fitness with Mrs. Stelzner**

This week The students were working on their summative assessment for the first unit, The Health Triangle. The summative assessment consisted of a vocabulary section and an practical application portion, connecting the triangle with the IB Learner Traits. The Tuesday/Thursday class was able to work on some fitness on Thursday's second half of class. We went over the technique and physiology of a squat, followed by wind sprints to help flush out the lactic acid produced by our squats.

**Exploratory: Visual Arts with Ms. Newstadt**

Artists have been experimenting with drawing techniques, focusing on contour lines and observation of shapes, textures, sizes, relationships in visual objects. We have completed practice drawings and projects in drawing paper sacks (focusing on lines, texture, value, and emphasis); perspective drawing (horizon lines, vanishing points, block letters, ruler use); oil pastel landscapes on cut paper inspired by the artwork of Georgia O'Keeffe and Idaho landscapes (shape, color, line, texture, scale, composition); and tree/nature drawings with colored pencils (observation, appreciation, line, shape, color, texture, balance).

After an introduction to self portraits via viewing and discussing the work of master painters including Van Gogh, Cezanne, Goya, Munch, Velasquez, Gauguin, Modigliani, and Picasso, students were taught about proportion guidelines of the human face on Thursday afternoon. They partnered up as artist and model with other art students to draw the shapes and lines of the face. Beginning on Monday of next week, students will study their own faces and use contour lines to draw a self portrait before completing a mosaic-type collage on top using magazine cut outs.

**PLEASE COLLECT AND BRING MAGAZINES TO ART CLASS FOR THE PURPOSE OF CUTTING THEM UP FOR MONDAY. Thank you!!**
