Standards emphasized: 5. Chemical reactions are processes in which atoms are rearranged into different combinations of molecules. As a basis for understanding this concept, students know: c. chemical reactions usually liberate heat or absorb heat. 7. The organization of the Periodic Table is based on the properties of the elements and reflects the structure of atoms. As a basis for understanding this concept, students know: c. substances can be classified by their properties, including melting temperature, density, hardness, specific heat, and electrical conductivity. 4. The structure and composition of the universe can be learned from the study of stars and galaxies, and their evolution. As a basis for understanding this concept, students know: b. the sun is one of many stars in our own Milky Way galaxy. Stars may differ in size, temperature, and color. 9. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept, and to address the content the other three strands, students should develop their own questions and perform investigations. Students will: d. recognize the slope of the linear graph as the constant in the relationship y=kx and apply this to interpret graphs constructed from data. e. construct appropriate graphs from data and develop quantitative statements about the relationships between variables. f. apply simple mathematical relationships to determine one quantity given the other two (including speed = distance/time, density = mass/volume, force = pressure x area, volume=area x height). g. distinguish between linear and non-linear relationships on a graph of data. |

CLASS MEETING AGENDA/ ACTIVITY |
|
MEETING 1 |
[1] Grade/Collect/Pass out new PS SKW [2] Finish the "Amount of Energy vs. Intensity of Energy" scientific investigation. |
MEETING 2 |
[1] Science Festival Project: Problem, Literature Review, & Hypothesis [2] Introduce Temperature Scales and Conversions (PS SkW) [3] Introduction to Phase/State Changes in words and graphs. [4] Pass in POW, "Bobo and the Soda Vendors". |
HOME SESSION AGENDA/ ACTIVITY |
|
SESSION 1 |
[1] Make sure PS SkW and /or PS POW are begun or finished. |
SESSION 2 |
[1] Write a "Here I Stand" in your ISSN for what you learned during the last 3 class meetings. [2] Text Reading, re-read page 173-178 |
SESSION 3 |
[1] Work on identifying a problem that you7 would like to base your Science Festival Project on. Then start finding some information about the main topic of your problem so that you can develop a hypothesis to test. Have a ISSN copy and a copy to hand in. DUE before the Thanksgiving Break |
