2) Describe the difference between the 2 processes
3) Create a t-chart that lists examples of both processes
Station 4: Acid Test for Rocks
1) We have said that the Huasteca and Monterrey are mostly limestone. Read about limestone on geology.com
2) How could you use the materials provided to test to determine which of the rocks are limestone?
3) Record your procedure for how you will test this
4) Record your observations for what happens when you test each rock
5) Make and record an inference (or claim) about the following question - which rock is limestone? Explain what evidence makes you think so.
Station 5: Observing rusty rocks
1) Examine the rock. Why would I call it "rusty"?
2) Record observations about the rock
3) Make and record an inference that answers this question: How did the rock get rusty?
4) Draw and color a diagram of the rusty rock
Station 6: Online activities and card sort
1) Complete the following 2 online activities in your group
- Shape It Up: An Earth Changing Erosion Game
- Web Rangers Activity: Rock Around the Park
2) When done, complete the card sort by sorting the scenarios into 3 piles - one for weathering, one for erosion, and one for deposition

Closure:
1) Turn to p. 59 - record the date and title it Lab Summary
2) Answer today's goal question on this page
3) Write 3 sentences explaining what you learned today during the lab
Week 12, Day 3
PTT:
1) Observe the sediment samples in the 3 jars as they are passed around
2) Finish yesterday's lab as needed
Task 1: Percolation Rate Demo 1) Title p. 60 - Demo: Comparing Soil Samples 2) Record the essential question and the date Goal Question: How are different types of soils/sediments affected by water? 3) Watch the demo to compare how water flows through different types of soil 4) Fill in the chart below using the class data from the demo and then the internet to find grain sizes for different soil types (this goes on the top half of p. 60)
Soil Type
Grain Size
Percolation Rate
Absorption Capacity
Gravel
Sand
Silt
Clay
NOTE: You can find the grain sizes in the chart below:
Wentworth Scale.gif
Task 2: 1) Read the information below Background Information:
The particles in the soil have settled out into layers, with the heaviest particles settling first, at the bottom.Gravel sized particles will settle almost immediately and form the bottom layer. Sand particles will settle next and form a layer on top of the gravel.Silt particles will settle next and form a layer on the sand. Clay may take over a day to settle on top of the silt and sand. Humus (fertile soil) may act as silt or clay sized particles, or it may be partly decomposed material that will float. Different types of soil will settle out differently. The amount of open space between particles has a lot to do with how easily water moves through a soil and how much water the soil will hold.
NOTE: The longer it takes for the water to appear, the greater the absorption capacity of the soil.
2) Below the chart, define in your own words the terms: pore space water percolation rate absorption capacity
3) Review: watch this video that summarizes what we learned from the demo
4) On the bottom of p. 60, record this question with the correct answer: 1. If soil has lots of pore spaces, then its percolation rate will be........ and its absorption capacity will be.....A. high, high B. high, low C. low, high D. low, low E. None of these are correct.
Task 3: 1) Title page 61: Comparing Water Percolation through Soil 2) Copy the chart/table AND make a bar graph using the information below:
In an experiment to measure the soil’s ability to hold water, particle size and the amount of humus the soil contained were tested. The data table below shows the results. Use the data to construct a bar graph that represents the relationship between the amount of water retained and the size of the soil particles.
