This curriculum uses this D.L. Jamerson design process to establish and define the IDEAL environment. The resulting curriculum relies on energy, mass, and momentum conservation principles to merge a Florida Standards base elementary school education with an engineering focus to emphasis the interdisciplinary symbiotic dependence engineering has with mathematics, science, the language and performing arts, physical education, and history

Jamerson pre-preschool July 18, Engineer s Toolbox Professional Development is Critical for Program Success Mathematics The mathematics building block as utilized by an engineer is the ability to manipulate NUMBERS, SCALERS, and VECTORS. A tangible, valuable, and useful gift from you to your students is a continuous development of mathematics as an integral part of their education in all subjects.

Scalar examples are fun!!!! 1 dozen donuts+ 1 baker s dozen donuts =? 25 donuts 5 kilograms grams =? 5.1 kilograms 1 million dollars + 50 cents =? $1,000, But vectors always point the way. A vector is a mathematical element that has a scalar component and a direction component. Vectors are used to describe and manipulate many important concepts related to our life and world.

Vector mathematics You can add, subtract, multiply and divide vectors. However, these operations for vectors have a specific set of mathematical rules. These rules are easy to learn. They are similar to the rules for numbers and scalars. They should be introduced to and practiced by students as soon as possible. Integrating Engineering into Elementary Education D.L.

27 Engineer s Toolbox Professional Development is Critical for Program Success Conservation of Linear Momentum The moving ball slows down as much as the stationary ball speeds up. These ideas may lead to trouble in River City but they are very useful for teachers to think about molecular motion in the gas state. (wind, pressure, volume, temperature, etc.).

28 Engineer s Toolbox Professional Development is Critical for Program Success Conservation of Linear Momentum An object s momentum, p, depends on its mass, m, and its velocity, v. This can be written as a mathematical model. momentum = mass x velocity p = m x v If the 2 billiard balls on the previous slide are a closed system, then the sum of their momentums before the collision is equal to the sum of their momentums after the collision.

31 Take Home Message(s) Don t get involved until you are really ready to be involved. Count on the teachers to know how to get the concepts across to their grade level. Count on the teachers not to know which concepts are needed to get across to their grade level. Get your persistence prescription refilled.
