Middle School Disco Dance!https://photos.app.goo.gl/lYzAE8taYSgOiWCW2A big shout our to our 7/8 Student Council for organizing a successful dance! They hosted 152 middle schoolers for a night of fun! 7th Grade Social StudiesBig Idea: Synergy Essential Question: How and why do structures unite? After discovering the "ingredients" leading many European countries to synergize and expand their empires, students had fun creating "Recipes for Imperialism." (pictures below) Students gained empathy for the plight of those who lost their jobs, incomes, and life savings after the Great Crash of 1929 as they participated in a simulation of the Worldwide Great Depression. (pictures below)Guiding Question: Can synergy exist in, or result from, war? Students were guided by this question as they reflected on their learning of WWI. They created black-out poetry as an expression of their interpretation of the synergy, or lack of it, in the war. Then they wrote personal reflections of their learning experience. (pictures below) 7th Grade English Language Arts ELA and SCIENCE Integration7th Grade Science In Science, we have been learning how SYNERGY between DNA, genes, and chromosomes contributes to the characteristics of all living things. We have had a lot fun exploring our own traits and learning how dominant and recessive traits are passed down from parents to offspring. While learning about DNA, we were able to extract this important molecule from strawberries. The students were able to extract a large amount of DNA and were fascinated by the stringy nature of this vital molecule of life. We also began an experiment to study the effect of the environment on the expression of genes. Each student planted a corn seed from parents that carried a recessive trait for albinism (no pigment). We are growing some of the plants in the light and some in darkness. We are learning that a recessive gene as well as lack of light could cause plants to grow without pigment. Finally, students have been considering the potential uses of some genetic technology, such as cloning. In ELA and Science, students have had an opportunity to explore the process of cloning and consider the advantages and disadvantages. Through in depth article analysis in ELA, and scientific exploration of the process in Science, students are developing a deeper understanding of the potential benefits and dangers of this emerging scientific technology. Within the past few weeks,Algebra 1 - Mrs. Cooler Algebra students worked on creations of their own design and then used linear binomials polynomials to calculate perimeter and area of the designs they came up with. Their hardworking was documented and can be seen in the photos above.Most recently, they finished their study on factoring the polynomials they learned to create in the previous chapter. This is a very big skill which can be used in finance: a common polynomial equation that comes up is the calculation of present value. This is used in accounting when the present value of assets must be determined. It is used in asset (stock) valuation. It can further be used in bond trading and mortgage calculations. The polynomial is of high order, for example, with an interest term with exponent 360 for a 30-year mortgage. This is not a formula that can be factored. Instead, if the interest needs to be calculated, it is solved for by computer or calculator. 7th Grade Math- Mrs. KolbOur math students Second period students discover the Triangle Inequality Theorem by using different lengths of construction paper to build (or not) triangles. They discovered that if the 2 smaller sides added together were larger than the largest side, a triangle could be made. Third period students are classifying triangles based on their sides and angles. Some decisions were hard to make while others were a little easier. Third and fourth period students used Play Doh and 3-D shapes to determine cross sections. With the model as their guide, students formed a shape (cube, cone, cylinder, square pyramid, triangular pyramid, hexagonal prism, etc) and then used dental floss to make either a vertical, horizontal or diagonal cut through the play doh in order to see the shape that was made. |
