OpenSciEd Middle School science program addresses all middle school NGSS standards. This comprehensive science curriculum empowers students to question, design, investigate, and solve the world around them.
In this unit, students are introduced to ratios, rates, proportional reasoning, similarity and congruence. Students explore ratio as a comparison of two quantities. They discover that if the ratio between the corresponding side lengths and angle measures of two figures is 1:1 (i.e., the measures are identical), then the geometric figures are congruent. They learn that for two figures to be similar, their corresponding side lengths must be in proportion and their corresponding angles must be congruent. Students also explore the relationship between congruence and similarity, learning that al
The tide never rolls in quite the same way twice. Each swelling of the waves takes with it a little bit of the earth and leaves a little bit behind on the shore. In the same way, none of us arrives in quite the same world—and none of us leaves it unchanged. In Autobiographies and Memoirs, we will explore the unique ways in which each of us experiences the world. How do we each transform it into a place that is a little bit different—and completely our own?
The Student Literature Workbook
In one day, four lives weave together in unexpected ways. Virgil Salinas is shy and kindhearted and feels out of place in his crazy-about-sports family. Valencia Somerset, who is deaf, is smart, brave, and secretly lonely, and she loves everything about nature. Kaori Tanaka is a self-proclaimed psychic, whose little sister, Gen, is always following her around. And Chet Bullens wishes the weird kids would just stop being so different so that he can concentrate on basketball. They aren't friends, at least not unt
