Water Retention - No Problem With The Key (Vertebrates&Invertebrates) Investigation part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Students will search for land and aquatic life near a water retention pond on our school property. Students will begin to realize the importance of one organism on another. The students will go out and collect vertebrates and invertebrates at the site and identify them with a key. The students will record data by using a science notebook and a digital camera. They will later use their data and identification to be able to place each form in the appropriate vertebrates or invertebrates group.
How high is BIG? - using an astrolabe part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Students will search for and measure "how big" poles, equipment, or buildings are at our school by using an astrolabe and the objects' shadows on the first day of school in each month throughout the school year. Students will begin to realize how measuring very carefully is important as the shadows length will change but the height of a fixed object should not. The students will begin to recognize patterns according to the seasonal changes of the Earth. The students will be collecting photographs and data for their objects they found on the school site. The students will collect and record their data by using an astrolabe, digital camera, and their science notebook. They will be able to use their data and documentation to place each labeled object with it's shadow in ascending order by month on a SMARTBoard Notebook page that will be presented to the class.
Investigating Plastic Polymers: Building a Model and Relating to Real Life Connections part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Students will use their prior knowledge about changes of matter including physical and chemical changes from the Houghton Mifflin science curriculum. Students will create a hypothesis to test the physical properties of materials such as plastic (polymers) and how its chemical properties allow it to have unique physical properties. Students will also be examining and categorizing various types of plastics (polymers) to identify where they are found in everyday life.
Where in the world can I find Plastic Polymers. Why are they used? part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Students will need to have basic prior knowledge about physical and chemical changes in matter. Our students will be using the prior knowledge they gained after completing the (2007) Houghton Mifflin science curriculum Chapter: Matter Changes pages E2-E29. Students will create a T-Chart as to where they think they will find plastic polymers vs. where they actually found plastic polymers in daily life, along with possible reasons for why they found certain plastic polymers in a certain place. Students will perform tests to determine the physical properties of some of the plastic polymers they found and hypothesize how its chemical properties allow it to have unique physical properties. Students will also be categorizing various types of plastic polymers from their T-charts into groups to identify where they are typically found in everyday life. The students will then complete an online website activity and enrichment activity, followed by an online test to determine student understanding.
