The big question addressed in lab, and a description of what you did. How do we know that the Goldfinch is in danger in Iowa? whats happening in Iowa average temp increacted by 0.2F over last 30 years Iowa is getting wetter more rainfall April, may, and june 4-6 inches per rainfall path forward agriculture is a big part of solution removing air pollution through land protection carbon sequestration - help maintain praries and stop interupting nautral cycle of carbon preventing pollution of air and water conservation can help absorb greenhouse gases protect land long-term by helping plains and the soil providing habitat for wildlife protexting wildlife homes so they can freely live is important river corridors or large tracts building resilient communities protect native ecosysyemsd by keeping praries clear so they can absorb water and help it flow to rivers and streams The second part of class my g...

science 2 week 12

The big question addressed in lab, and a description of what you did. REVIEW: Different types of sand: water (ocean)- polished, smooth, similar in size glaciers - polished, smooth, irregular wind (dune) - opaque, fine grained, frosted, pitted characteristics of water eriosion - (1) headwaters, most gravity, moving faster, can carry mroe sediment - (2) TRANSFER ZONE, starts slowing down (3) depositional zone, U shaped river basin when glaciers move acorss land, make U shaped valleys, not moving super fast Transitioned into Climate Science Measuring & Mapping, Precipitation in Iowa How do we know if the goldfinch is in danger in Iowa? I think they are starting to become endarged due to the evidence, but slowly. There has been an increase in rainfall which makes it harder for birds to survive. A description of what you learned in Thursday's lecture. We took an exam during lecture. Answer questions abou...

week 11 science 2

The big question addressed in lab, and a description of what you did. We started lab having small and whole group discussion about formative assessments and teaching students based off of their questions. Next, we did an activity to determine 'who came first' which translates to how we are currently learning about things in earths history that occured first. We did an invesigation to determine what came fist in the principle of superposition. - rocks form layers that become buried under more layers over time, the deeper we dig, the farther back in time we see. Fossils found deeper and deeper mean it gets older and older. We also looked at the layers of earth. 1. sandstone 2. mudstone 3. limestone 4. volcanic ash 5. granite (shifts up, lead to fault line) sand created through water is polished, smooth, similar in size glaciers, polished, smooth, irregualr in size wind A description of what you learned in Thursda...

week 10 science 2

The big question addressed in lab, and a description of what you did. In lab we discussed how we decide if something is a rock. - coal, hardended lava, limestone, gravestone, iron ore, marble statue, and granite. we also discussed the importance of how to asses our students as well as how to create activities that are relavent to their questions and prior knowledge we also discussed the layers of the earth - core (heat), mantle, crust (tectonic plates) when tectonic plates collide they can create mountains, if land and water plate tectonic occur one goes on top of the other igneous rocks- when magma cools sedimentary - compaction and cementation (squished together) metamorphic - heat and pressure A description of what you learned in Thursday's lecture. Earthquakes Plate tectonics Continental Ticker, stick up above the water Averages 20-30 miles thick Oceanic In the ocean basin 10 miles thick ...

week 9 science 2

The big question addressed in lab, and a description of what you did. We talked about when things appeared/were created on earth. our table groups timeline: 4000 mya oldest rock on earth 3400 mya 1st life on earth 2400 mya great oxygenation event 470 mya first land plants 200/300 mya pangea formed A description of what you learned in Thursday's lecture. we took an exam during lecutre. Answer questions about the weekly textbook reading What did you learn? For the text book reading, I completed the practice quiz for our exam. I learned about the history of the earth by looking at it represented on a clock. It was a different perspective and showed how spread out everythig really is. Humans were not on Earth until close to midnight on the clock example while rocks formed on earth occured so long ago (billions of years) What was most helpful? The graphics were extremely helpful and descriptive when looking at ear...

week 8 science 2

The big question addressed in lab, and a description of what you did. We presented our presentations today, here are some notes from each presentation origin of the universe big bang theory' the universe is exapnding and has no center stars formed 200 million years after Life cycle of Stars stars are not the same size, giant, dwarf, super giant stars are constantly moving stars are all diferent colors ( misconceptions is stars are only yellow) 7 stages giant-gas clod protostar T-tauri phase main phase red giant - temp cools down elemental fusion supernova/white dwarf Origin of the Earth evidence that earth was formed before the Big Bang formed slowly through many collisons earths surface has changed over time Black Holes light was dedected in black holes vary in sizes depedning on mass radiation escapes black holes so dense gravity lays below ...
