Science

When you want to move somewhere, you probably stand up and use those muscular legs to transport yourself!  But what if you were a rock?  How exactly would you get to a new location?  After studying how large rocks break into smaller rocks for a couple weeks, your scientists have moved on to asking how these smaller rocks then move from one place to another.  With the use of a stream table model, 5th graders investigated the movement of sand and silt under a normal rain condition.  We noticed a couple of things!  First, we noticed that the lighter material, silt, was picked up first by the water and moved farther than the sand.  Then, we noticed that the water created valleys, canyons, and alluvial fans in our earth material.  Next week we will look at how earth materials move during a flood situation!

Math

Your fifth grade mathematicians continue to work like middle schoolers as they expand their use of algebraic expressions.  Now that they have a strong understanding of what an algebraic expression is, they applied this knowledge to real world situations in the form of rules and formulas.  One formula we used was a way to predict when Old Faithful Geyser would erupt.  After using the formula to calculate certain values, your bright students graphed these values on a two-coordinate grid.  Creating a line graph allowed them to make predictions for a variety of scenarios.  We practiced this skill over and over again using different formulas and graphing our results.  Ask your child what they find interesting about algebra!
