Measurement,+Calculations+&+Error+Analysis

__** Content and Technology Standards for Lesson #1 **__
 * 1) High School (Physical Science Standard #2): Matter has definite structure that determines characteristic physical and chemical properties.
 * 2) NETS for Students #3 (Research and Information Fluency): Students apply digital tools to gather, evaluate and use information. (a) Students will plan strategies to guide inquiry (d) Students will process data and report results.

__** Objectives of Lesson #1 **__ Students will know that: Students will know how to: Students will be able to apply what they learned to:
 * 1) density is a physical characteristic of matter.
 * 2) density is a ratio between the mass and volume of an object.
 * 3) density is a quantifiable measurement that can be used to describe matter.
 * 4) the density of an object changes with temperature.
 * 1) measure the volume and mass of an object.
 * 2) calculate the density of an object.
 * 3) compare the relative densities of various objects.
 * 4) increase or decrease the density of an object using energy inputs.
 * 1) the movement of air
 * 2) the movement of water
 * 3) the movement of the plates

__ ** Materials Required ** __ For this activity, you will need to print out the 2 (two) forms listed below under the "Graphic Organizer" section; you will need to access to the internet to use the Density pHet simulation (also linked below) and lastly, you will need to review the density lectures that have been covered in previous classes and those listed under multimedia materials.

__** Instructional strategies to meet the needs of at least one other diverse learning group **__ This activity is designed to be self-regulated and allows for students to work at their own pace. The use of the multi-media tools allows students to access review materials ranging from a basic understanding of the science content standards through to advanced content dealing with the density of gases and voice patterns. Students who enter this activity with an understanding of the properties of density will be able to add to their content knowledge and improve on the technology standards or add to the depth and complexity of their understanding. Students who begin this unit with less of an understanding about density will be able to meet the content standards for both science and technology. The use of this wiki allows for self guided learning and the assessment choices listed below allow students to gauge their knowledge relative to the expected outcomes.

__** Graphic organizer **__ The "Things That Float" Form The "KWL" Form

__** Multimedia Tools **__ Lecture #1 Lecture #2 Review Game media type="custom" key="23533510" Density of gases can do some funny things!

__ ** Problem-solving applications ** __ Density Simulation Application (pHet) Movement of Air Masses Movement of Surface Waters Movement of Plates (apps for smart phones) __** Assessment Options **__ Students have three (3) choices in relation to the demonstration of desired outcomes for this activity. Those choices are listed under "Objectives": Students will be able to apply what they learned to:
 * 1) the movement of air
 * 2) the movement of water
 * 3) the movement of the plates

In order to be successful, students will extrapolate the importance of density as it relates to one of the three basic Earth Science principles listed above. The format of the assessment is a 3-5 minute presentation. Students will have the flexibility to select an application of their choice if they prefer to use technology (wiki, prezi, keynote/powerpoint as examples) or a non-technological presentation (poster, diagrams/drawings, interpretive dance as examples). Please refer to this Lesson #1 Rubric for specific information about the assessment.
