4/28/2008 Math 2a
1. HOMEWORK Due today: Draw a cylinder, a cone and a sphere.
2. Discuss information regarding cylinders, cones and spheres.

Find the volume of a Cone, Sphere or Cylinder:

	Enter the *radius* : Enter the height :	The *height* dimension is not used on a SPHERE. The formulas used are: Cone - V= ¹ / ₃ πr ² h Sphere - V= ⁴ / ₃ πr ³ Cylinder - V=πr ² h

2. Data Collection for Average student displays

OBJECTIVE: 1.1.4 Understand the concept of direct proportion. 1.2.5 Use formulas to determine measurements related to circles, triangles, and rectangular prisms.4.1.2 Extract numerical, measurement, geometric, probability, statistical, and/or algebraic information from multiple sources. ACTIVITIES/ASSESSMENT: Data Collection for Average student displays. Will collect height in cm, weight in kg and calculate the surface area and volume of each student and the class average. (Spreadsheet information) This information will then be collated to create a standard length (height), an average surface area (model) and average volume for the class. Will also apply box and whisker plots. NOTES: HOMEWORK: Handout-Tag Sale B

2. Continue Body Measures

Surface Area Information

A very good first approximation for body volume is to simply find the average human mass (easy enough to weigh) and divide by 0.001 kg/cm^3.

2. Complete data of surface Area and Volume
3. Establish teams for solar system model planets and distances

OBJECTIVE: 1.1.4 Understand the concept of direct proportion. 1.2.5 Use formulas to determine measurements related to circles, triangles, and rectangular prisms.4.1.2 Extract numerical, measurement, geometric, probability, statistical, and/or algebraic information from multiple sources. ACTIVITIES/ASSESSMENT: Complete data of surface Area and Volume. Establish teams for solar system model planets and distances. From the data sheet, students will determine a scale for a set of model planets and a scale for distances in our solar system (from the sun) They will discus and prepare a report of a solar system model based on Pluto (the smallest object)[probably a hole-punch piece] NOTES: Review metric measures and conversions; also proportion.

2. Form Teams - assign model makers, calculators, etc.(both systems)

OBJECTIVE: 1.1.4 Understand the concept of direct proportion. 1.2.5 Use formulas to determine measurements related to circles, triangles, and rectangular prisms.4.1.2 Extract numerical, measurement, geometric, probability, statistical, and/or algebraic information from multiple sources. ACTIVITIES/ASSESSMENT: Divide students into performance teams to construct the outcomes of these 5 exercises. •box and whisker plots for ht, surface area and Volume (3 feet long); •average height, average surface area (actual size)(colored paper); •average volume (actual size)(cardboard); •Planet Models (partial sun) to scale; •Solar system distance (to scale)Object markers at a distance.
