Lesson Objectives

As a result of activities in grades 5-8, all students should develop:

• |
Understanding about scientific inquiry. |

• |
Abilities necessary to do scientific inquiry: identify questions, design an investigation, collect and interpret data, use evidence, think critically, analyze and predict, communicate, and use mathematics. |

• |
The learner will recognize examples of motion and force in the physical world. |

• |
The learner will demonstrate that an object in motion will stay in motion or an object at rest will stay at rest unless acted upon by an outside force. (Newton’s First Law) |

• |
The learner will determine that acceleration is produced when a force acts on a mass. The greater the mass, the greater the amount of force necessary to accelerate the mass. (Newton’s Second Law) |

• |
The learner will conclude every action is followed by a reaction equal in magnitude and opposite in direction. (Newton’s Third Law) |

• |
The learner will understand that fluid mechanics is the study of gases and liquids at rest (fluid statics) and gases and liquids in motion (fluid mechanics). |

• |
The learner will understand that any material that flows is a fluid, which has no fixed shape, and changes its shape continuously when acted on by an external stress. |

• |
The learner will identify a fluid as a liquid or gas. |

• |
The learner will determine there are a number of characteristic properties of fluids such as density, viscosity, surface tension, and compressibility and that they are responsible for phenomena such as pressure, buoyancy, and aerodynamic lift. |

• |
The learner will conclude there are more than 100 known elements that combine in a multitude of ways to produce compounds, which account for all living and non-living substances. |

• |
The learner will demonstrate that atoms combine to form molecules and molecules formed from different atoms combine to form compounds. |

• |
The learner will identify a fluid as a liquid or gas. |

• |
The learner will recognize a substance has characteristics, such as density, viscosity, boiling point, and solubility, all of which are independent of the amount of the sample. |

• |
The learner will understand that energy transfers in many ways, such as heat, light, electricity, mechanical motion, sound, and the nature of a chemical. |

• |
The learner will conclude a change in the state of matter of a substance is the result of a change in kinetic energy. |

• |
The learner will differentiate between a physical change in which matter changes state or form and a chemical change in which one or more new substances are formed. |

• |
The learner will understand all energy can be classified as potential energy (such as chemical, mechanical, nuclear, and gravitational energy) or kinetic energy (such as radiant, thermal, motion, sound, and electrical energy). |

• |
The learner will investigate current and/or emerging technological innovations. |

• |
The learner will identify current and/or potential real-world applications of technological innovations. |

• |
The learner will employ current and emerging technologies to solve a simulated or real-world problem. |

• |
The learner will use multiple processes and diverse perspectives to explore alternative solutions. |

• |
The learner will recognize the engineering design process is a method of problem solving used to create a system, a product, or a process that meets an identified need. |

• |
The learner will apply the steps of the Engineering Design Process to solve a simulated or real-world problem. |

• |
The learner will construct a 3-D scale model based on geometric relationships using engineering design software and computer technology. |

• |
The learner will use engineering design software to demonstrate basic CAD operation and skills in the areas of: - sketching (2-D geometry creation and modifications) - geometric and dimensional constraints (applying appropriate constraints) - modeling (3-D modeling skills and modifications) - assemblies (understanding and creating simple assemblies) |

• |
The learner will relate geometric relationships and mathematical applications to parameters of CAD. |

• |
The learner will apply basic computer skills such as mouse dexterity, keyboarding, data entry, and folder navigation. |

• |
The learner will solve problems using fractions, decimals, and percents. |

• |
The learner will apply appropriate standard units and tools to measure length. |

• |
The learner will apply appropriate standard units and tools to measure liquid volume. |

• |
The learner will apply appropriate standard units and tools to measure mass. |

• |
The learner will recognize geometric properties and relationships and apply them to other disciplines and to simulated or real-world problems. |

• |
The learner will collect data using observations and experiments. |

• |
The learner will represent data using tables and graphs. |

• |
The learner will collect and analyze data to identify solutions and/or make informed decisions. |

• |
The learner will develop an awareness that scientists, technicians, engineers and mathematicians work on military facilities. |

• |
The learner will correlate their academic endeavors in STEM areas to real-world applications in career fields. |
