MS-+UBD+Stage1

Simple Machines Unit Stage 1 Science, Standard D: Physical Science Performance Standards - Grade 4 D.4.7 Observe and describe physical events involving objects and develop record-keeping systems to follow these events by measuring and describing changes in their properties, including: · position relative to another object · motion over time · position due to forces Science, Standard G: Science Applications Performance Standards - Grade 4 G.4.4 Identify* the combinations of simple machines in a device used in the home, the workplace, or elsewhere in the community, to make or repair things, or to move goods or people G.4.5 Ask questions to find answers about how devices and machines were invented and produced
 * Established Goals:**

Students will understand: · How certain tools work, the properties of work, and how they are made to perform specific jobs. · How simple machines make work easier, and how they are applied and combined in familiar tools and machines. · The functions of each of the 6 simple machines. · That Elijah McCoy was instrumental in the invention of a machine to reduce friction. · Why is it important to understand the purposes of different uses of machines? · How can the proper use of simple machines or complex machines benefit us?
 * Understandings:**
 * Essential Questions:**

Students will know: · Characteristics of each of the 6 simple machines. · How simple machines are used to make work easier. · What friction is and how it can be reduced. · Elijah McCoy’s relevance to the invention of simple machines.
 * Knowledge and Skill:**

Students will be able to: · Name different types of machines and how they work. · The student will explain that when work is done, if the effort increases, the distance decreases, and vice versa. · Identify the six basic simple machines. · Explain that simple machines can be combined together to make a complex machine. · Identify Elijah McCoy and how he contributed to the technological world today. **Performance Tasks:** “Simple Machine Fair” Project and Presentation **Other Evidence:**
