Maximum Score - 12 points


1. Data Table
2 points total
Standard: The student will determine the actual volume of soil and water and record it correctly for the data table. The student will also calculate and record the difference between the total and the actual values.

Criteria:

A. correct recording of the actual volume of air and soil mixture. Allowable variation +/- 10% of teacher's determination. 1 point

B. correct recording of the difference between the student's total and actual values. 1 point

 
Comment 1: Students should be given points based on their data even if it was incorrect for actual volume.

2. Percentage of Air
2 points total

Standard: The student will calculate the percentage of air in the soil based on their data.

Criteria:

A. Substitution of values correct. 1 point

B. Calculations correct based on the values substituted. 1 point


3. Why Soil with Pore Space is Good
2 points total

Standard: The student will write a logical statement that relates pore space to water storage and availability for plant usage.

Criteria:

  • A logical and reasonable explanation using complete sentences. 2 points
  • Logical and reasonable answer, but not in complete sentences. 1 point

4. Experimental Plan
6 points total

  • a statement or question for a problem
  • formulated hypothesis
  • list of materials
  • a specific procedure to collect data
  • identify variables
  • a way to present, analyze, and report data
