STANDARDS/ |
Science Standards: 1.2 analyze and apply Newton’s three laws of motion. 1.3 relate gravitational force to mass. SPI choose the illustration or scenario that relates the effect of gravitational force on falling bodies or satellites. TPI demonstrate the effect of gravity on objects. SPI solve application problems related to velocity, acceleration, force, work, and power using appropriate units of measurement, given the equations. SPI solve application problems related to velocity, acceleration, force, work, and power using appropriate units of measurement, given the equations. TPI gather and analyze data to solve problems related to velocity, acceleration, force, work, and power, given the equations v=d/t, a=∆v/t, F=ma, W=Fd, and P=W/t. SPI distinguish among the concepts inherent in Newton’s three laws of motion, given a scenario. TPI evaluate scenarios that illustrate Newton’s three laws of motion
Math Standards: 1.10 select and apply an appropriate method (i.e., mental arithmetic, paper and pencil, or technology) for computing with real numbers, and evaluate the reasonableness of results. 2.6 apply the concept of variable in simplifying algebraic expressions, solving equations, and solving inequalities. 4.5 demonstrate an understanding of rates and other derived and indirect measurements (e.g., velocity, miles per hr, rpm, and cost per unit). |

SUMMARY OF PERFORMANCE ASSESSMENT |
Students will be expected to explain gravity and its effects. They will understand how gravity affects different objects, and why. Students will be able to use their knowledge to solve problems involving gravitational force, and they will be able to explain how to determine the force of gravity using experimentation.
Students will be able to take experimental data and use that data to solve algebraic problems and formulas. |
