Description:

This is a multi-day instructional unit for middle school science on kinetic and potential energy. Through investigations of waterwheels, roller coasters, bouncing balls, and a pendulum, students get a feel for energy transformation in a mechanical interaction and build accurate concepts about the Law of Conservation of Energy. The unit also introduces static and kinetic friction, drag, elastic/inelastic collision, and students learn to calculate frictional force. Lessons are all aligned to AAAS Benchmarks, and may be conducted separately or in concert. Editor's Note: Understanding mechanical energy is at the root of many engineering applications in our world. This set of lessons provides inquiry-based exploration, while also introducing simple calculations in the context of real-life situations. It is developmentally appropriate for middle school, but will definitely challenge students. TeachEngineering is a Pathway project of the National Science Digital Library. It provides a large collection of teacher-tested, research-based content for K-12 teachers to connect real-world experiences with curricular content.

Recognize and represent proportional relationships between quantities.

CCSS.Math.Content.7.RP.A.2a: Common Core State Standards for Mathematics

Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.

CCSS.Math.Content.6.EE.A: Common Core State Standards for Mathematics

Apply and extend previous understandings of arithmetic to algebraic expressions.

CCSS.Math.Content.6.EE.A.2: Common Core State Standards for Mathematics

CCSS.Math.Content.6.EE.A.2c: Common Core State Standards for Mathematics

Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).

CCSS.Math.Content.6.EE.B: Common Core State Standards for Mathematics

Reason about and solve one-variable equations and inequalities.

CCSS.Math.Content.6.EE.B.6: Common Core State Standards for Mathematics

Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.

CCSS.Math.Content.7.EE.B: Common Core State Standards for Mathematics

Solve real-life and mathematical problems using numerical and algebraic expressions and equations.

CCSS.Math.Content.7.EE.B.4: Common Core State Standards for Mathematics
