Welcome to AP Environmental Science. Look here for assignments and other updates throughout the year. Check the APES Docs Button for class handouts.
11/16 Finish soil chapter questions. Soils test will be Thurday 11/18. Tues in class we will test soil percolation, porosity and pH. We will aslo set up Berlese funnels and determine the % organics in your sample (the soil samples I cooked). Please read ahead to see what you will be expected to do. You will have to divide the labor to get throught the lab in one period. Per 2 we will introduce desertifiction and view a film.
11/17 Complete Soil Lab questions. Early on we determined our soil types both qualitatively and quantitatively. As you look a the rest of your results, ask yourself whether you think they are consistent with the soil type you think you have. Question 5 in part 2 requires you to consider percolation data in your answer. Question 7 in this section asks you to tell what you know about how soils are formed. Essentially – why are there different particle sizes? Calcs in part three should be clear - show work - but I am open to your thoughts in question 3 of part 3. Part 6 requires calculation. Note that percolation is a rate so time must be included int the answer. The units are
ml water /cm2 (surface area)/second. You should have all the info to calculate this for sand and your sample.. In part three convince me that your results make sense. Part 7 - done in class. Part 8- You can't really answer question 2. Given that the forest where we got our soil is in pretty good shape, you should be able to predict the best soil pH for the plants there. Review which particle sizes represent sand , silt, clay then Look at the columns provided and figure out the soil types.
Finally – complete the lab summary questions.
The handout with notes summary may help you in your write up.
