Investigation 2 elearning
The students were placed in groups of four. Some groups of four were then working in pairs. The students moved in around the room in stations. The teacher acted as a facilitator in this lesson as well and provided help to the groups as needed. Students were on task on the video and recorded their information in their journals.
Investigation 2.2 Electronic Field Trip
Pima Point:
Why do some areas of the Grand Canyon have plants growing and other areas do not? Relevant question because it deals with the type of soil and rock formation that would allow plant growth and where the flood line of the Colorado River use to be prior to Glenn Canyon Dam.
Where is the best location to camp in the Grand Canyon? Not relevant because it does not tell us anything about the history of the Earth.
Lines in the cliff walls? Relevant because it has to do with layers of the Earth, what was in the area millions of years ago(covered by water), how the Earth formed over time, and how the river eroded through the rock layers.
Photo Exhibit:
Colors of rock and plant material. Relevant due to formation or Earth and conditions to allow plant growth.
Rock climbers. Relevant that it has to do with the type of rocks formed but not relevant if all we are interested in is the rock climbers.
Picnic. Not relevant (unless you are hungry)
Grand Canyon Rock Samples:
Pretty. Not relevant to formation of the rock
Gray and smooth. Relevant to effects of erosion and classifying rocks.

Investigation 2 Part 1
RIVER SONG
Powell Expedition
Realized the relationship between the Grand Canyon walls and the river: smoother walls=quieter water; rougher walls=rougher water.
Found the ruins of a house which was abandoned 700 years ago.
His expedition provided the basis for current knowledge of the canyon.
Grand Canyon
Glenn Canyon Dam created a new environment and controls the flow of the water.
There are “river waves” which look spectacular.
The walls were pushed above sea level 1 ¼ billion years ago.

Food Taken on Trip
Flour, sugar, coffee, beans, bacon and other food. 10 months worth of rations. Hope to add fresh meat and fish along the way.
Equipment Taken on Trip
Axe, hammer, saw, auger, other tools, ammunition, traps, nails, screws, sextants, chronometers, barometers, thermometers, compasses, other instruments.
Supplies I Would Take
Soap, food, fishing gear, cell phone, compass, flashlight, mirror, tent, sleeping bag.
Type of person Powell was
John Wesley Powell was a man who had a strong and determined personality. He set his goals and would not stop without achieving them. This is shown in his determination to explore the Colorado River. He climbed rock walls that were a challenge for any man. He also had a gentle side that he did not expose to people. This is demonstrated in his writings of the Grand Canyon.
CD ROM
How did the contributions of John Wesley Powell expand the field of scientific knowledge? How did these past scientific contributions influence current scientific understanding?
I don’t believe the slide show addresses these two questions. I then read it in the Teacher’s Guide and still could not find the answer. What I interpret as the correct response is as follows. Powell’s identified rock layers that would not make normally form in that area unless it was submerged under the sea. Also, the distinct layering of rock shows the millions of years it took to form the land. The process of erosion exposed these to scientists rather than keeping it buried in the Earth.

Investigation 2 Parts 3-4
I teach 6 classes so I took a general survey of my classes. The general categories were animals, plants, erosion, and rock layers.
Relevant question: Why are there layers in the walls? What kinds of rocks are there? How did the rocks get there?
Not relevant question: Do bears live in the canyon?I had to redirect their focus because some started asking questions about the animals in the canyon and became more interested in that than the rock formations and cliff wall layers. I continually asked questions similar to Why would sea fossils be found in the canyon walls were a fresh water river runs? Why are there different rock layers? Why are hard rock layers between soft rock layers? How does this affect erosion?

Envelope Critical Review
I reveiewed the envelope #2 that Errrin viewed. I would agree with her observations and inferences. I would add an additional inference though. Itcould be sent from someone in the military because it is sent from Michigan but has USA was included in the address. That person may be currently stationed overseas but their mail is postmarked through Michigan. I could not read the return address for other information.
Discussion Board
It was easier for many students to make observations about the envelopes rather than inferences. After discussing inferences again, and giving an example, they were able to understand the concept better. Some took it to an extreme, they were making inferences without any observation to back it up. For example, one student said the envelope fell in the mud when there were no dirt marks on it. When asked about this inference, he said it could have happened but didn't notice anything to give him that clue. Most of the students did a good job making at least 1-2 inference. Some needed more prompting. The students who seemed to have more experiences in their own lives were better able to make inferences. I really helped the students when showed them the sample list of observation/inferences on the overhead. Next year, I think I might show this first with a class and see if they give more in depth responses than the other classes.
After Mid-Summative Test
The student had a partial understanding of the lessons objectives. They were able to identify the difference between an observation and an inference; however, they had difficulty explaining why something was an inference. Specifically, only about 50% could cite the observation they used to determine if it was an inference. Excluding letter 'g' "student pleased with experiment." My students were able to identify the smile on the face as an observation for this inference. Letters 'b' and 'e' confused them. Some stated that "plants planted same day" was an inference because the observation was that they were different sizes. I had to go back and explain to the students to read the sides of the containers and use that as part of their observations. It seemed half the students overlooked this the first time.
