Matter
The junk materials lab was a really cool was to help us think about matter and classification. I liked this activity because something that sounded so easy became hard. The first classification of composure was easy to do but then when it came toe the usage classification it was hard because some of the materials were thing that are not commonly used or didn't exactly fit into the groups.I also liked the part with the baking soda because in the beginning we knew exactly what the materials were but after adding water to the baking soda it was hard to classify what type of matter it was even though we know the definitions of what each type of matter is. This made me think about how hard a concept like this would be for elementary children. When looking up the definitions for children some of the definitions were so complex that some adults might not understand.
Science Teaching Strategies
For the science article assignment I decided to read about a strategy used to help students learn science. This sparked my interest in other strategies. So I found a couple that I thought would be useful for an elementary classroom. One of the strategies was the five E’s . The first step of the five E strategy is to engage the children. Next invite the children to explore a little. Then have the children explain what they have learned and elaborate on it . The final step is to evaluate student work . this strategy seems to be the most commonly used in the classroom. Another strategy is to have students make plays of what they learned . This strategy is great because it gives the children a chance to teach what they have learned to others and this is one of the best ways children learn. Another strategy is the POE Strategy. The P in the strategy stands for Prediction in this step students predict what is going to happen. Next the children Observe what happens . The final step is to explain children explain if their prediction was correct , what they observed and why they think the outcome happened.
Some other ideas for helping to teach science are by doing case studies, role playing, making board games, web quests , virtual field trips, cyber guides , concept maps , Vee diagrams and multimedia presentations.
All of these strategies and ideas seem like they would be great to impliment in the class room .

The Ice Build Up
Through out the winter the ice has been building up in my drive way . I live in an apartment building and its very hard to get the drive way cleaned good because there are many cars that get packed in a tiny space . So from all of the cars driving over the snow it had become a thick sheet of ice . Since the temperature was nice for a few days we decided to finally try to break it down some. Little did we know the ice was about four inches thick . I could not believe ho thick the ice got. The drive way has no drain and there are many dips so when the snow melted any it just kept building puddles under the snow which in return built up more ice.

Frost
Today as I was driving to School I passed a lake that is turning into a swamp. The trees and plants that are growing in and around the water were covered in frost . The way the sun shined on them was beautiful. The sun made the ice reflect and shimmer . The sight was amazing. It made me wonder how exactly and why this happens in this area but not others. It was interesting to learn a little about why this happens.
Frost is the solid deposition of water vapor from saturated air. It is formed when solid surfaces are cooled to below the dew point of the adjacent air as well as below the freezing point of water.[1] Frost crystals' size differ depending on time and water vapour available. Frost is also usually translucent in appearance. There are many types of frost, such as radiation and window frost. Frost causes economic damage when it destroys plants or hanging fruits

Scientific Self
One thing that sparked my scientific self was that I was woken up by birds this morning!!! This reminded me of elementary school and being taught that all birds fly south during the winter. I always thought of the birds flying to warmer weather places like Florida . It helped me to realize that what is south for some birds is not the same south for all birds . It also made me reflect on what the birds could be eating , since most of the plants are dead or covered in snow . I was thinking of how cold it is and how small the birds are . It made me wonder how they stay warm in this weather because if humans are out in the cold our body temperature decreases and causes many problems. Those poor little birds!!!!!!
