Weekly Homework |
December 1 - 5 |
| Monday |
Botany science project due today. This has been an on going project assigned in September.
• On December 1st each team will bring the completed project to the science classroom. This will include a three fold display of the project that states the question and hypothesis with a description of the steps taken to test your predictions. You may include actual samples of the experiment or photos of your work. Each team will also be required to include on their display the analysis of the data they collected. You will show these results using tables and graphs. Make sure you include the names of each team member.
• Between December 1st and 4th each team will be required to make a 15 minute oral presentation to the class about their project. At the time of this presentation the team will also submit a paper that explains how each step of the scientific method was followed during the completion of project. (Please format the paper so each of the 9 steps of the Scientific Method are described on separate pages making a minimum 9 page paper. It is understood that not every step will require a full page.)
