## Reflection: Complex Tasks Using Scientific Formulas - Section 4: Evaluate

This math in this lesson is relatively easy because the students are plugging numbers into a formula. The science is far more difficult. The student learning goal in this lesson is to calculate the amount of power using a series of scientific formulas. I ask them to describe how mathematical equations make the job of the scientist easier.

An added benefit of this lesson is the introduction of complex science vocabulary.  The learning goal is not an understanding of the science concepts velocity, acceleration, force, work, newtons, and watts. I introduce the concepts as a way to understand the formula. I tie one of my previous lessons to the formulas.  My students have had my Kilowatt lesson so we review from their notebooks the definition of a watt.

In 7th grade my students were assessed on the concepts of velocity and acceleration. I review the concepts to build upon the formulas they will use in my class.

I then introduce the other vocabulary words. To introduce the concept of a newton, I have a meter stick and a kg weight. I challenge the students to push the weight with just enough force to make it stop at the end. My intention is to give the students a fun way to think about the concept.

After experience the force it takes to push the weight, I ask students to push one another with the force of one newton. We measure the distance and I explain the term "work".

These demonstrations build experience in the vocabulary and in understanding the relationship between math and science.
