Warmup: • Find your notebook. • Take out a ½ sheet of paper. Put your name on it. On one side, number 1-19. On the back, write numbers 20 and 21. For the first 19, the answer is only one letter, so you won’t need much space. • If you made notecards, take them out now and place them on the table in front of you.
Learning target: • I will demonstrate my knowledge of current class vocabulary on the first vocabulary assessment of the year. • I will learn from my mistakes during the paper platform lab and record that learning next to the error in my notebook.
Announcements: • You have 9 days to do your science video review – 2 hours worth of viewing – and write up the form as is written in notebook. • Graffiti master – do your job. If you miss something, your table might have to clean! • Today’s quiz is 75% of your current grade. That will lessen. • Extra credit EFFORT grades TBA. There is no extra credit for MASTERY grades.
During quiz: • No talking. • Make sure to write BEAVERs or DUCKs next to your name. • Letters only – no words in your answer except 20-21. • Leave them turned over to the back when you are done – I will collect at end. • Do the letter challenge if you need something to do. On the back. • 26 L in the A = 26 letters in the alphabet • 1) 100 Y in a C • 2) 3 F in a Y • 3) 7 D in a W • 4) 365 D in a Y • 5) 3 BM. SHTR.
Today the more you write… • The more your neurons will grow. • The more you learn. • Your mistakes are golden. • LEARN! • You can get there if you try – but it requires brain involvement.
Science fair check list: • Watch October Sky • Demonstrate mastery of the scientific method at your table group. • Demonstrate mastery of the scientific method on your own. • Research a topic – turn it into a question and submit T form. • All before Thanksgiving
How you can self check: • Take a highlighter and highlight the parts of your rubric as he demonstrates. • Read what excellent sections should have. If you are missing something, write it down. (different colored ink) • Look at the examples of different parts and see how you can improve yours.
Explaining problem: • Lifting a dictionary 10cm off the table with just a sheet of paper and tape is challenging but doable – here’s why. The paper has a small mass compared to the dictionary and also does not have a lot of structural strength to withstand a lot of compression force. Still, there is reason for hope. When we played with the materials and made a single cylinder out of paper, we were able to almost meet the engineering goal within ten minutes. We also read that different shapes can provide increased strength. With time, we should be able to make progress. • Using the background information, the problem is explained in detail.
Describe and evaluate possible solutions • 4 or more possible solutions to the problem are identified and evaluated based on the criteria (rules) • Are the proposed structures clear? • Did you propose four of them? • Did you write a list of strengths and weaknesses for each one?
Select a solution and explain why • One solution is selected as the best option and the reasoning behind the choice is explained. • We believe that the three columns will hold more mass than the two or one column structure. First of all, three columns will be much more able to balance the large book when it is lifted off the table. We already tried to balance it on a single structure and we failed. Secondly, three columns will better distribute the mass of the book over a larger section. Thus, even though there is less paper in each column, the advantages will more than offset the disadvantages. • Did you compare your solution to the others – are the others mentioned? Do you look at both sides?
Diagram • Did you remember the structures: • A) Dimensions (all of them) • B) Placement of tape • C) Exact placement of more than one structure • D) Could someone from another state rebuild your structure EXACTLY the way you made it? If not, then explain why.
Graph of results • Did you remember: • Graph Title • Label the Y axis including the units • Label the X axis including the units • Use even intervals with your numbers • Choose good numbers so your bars fill up a good chunk of your graph • Is it neat? Is it easy to read?
Problems and solutions • 6 problems collecting the data or in the design and possible improvements proposed. • Are the problems you identified relate to fairness or the integrity of the test? • Did you find a realistic way to solve each one? • Examples: Different size of text books, books not stacked straight, columns not made completely equal (different tape, amount of paper, height), table being bumped, placing books down with different force, etc.
