1 Part I.Review Game: Jeopardy
The Magic World of Biology and Chemistry Part I.Review Game: Jeopardy Day 2: Mrs. Dorcas Green and Ms. Arielle Darden Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

2 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Housekeeping Put time and effort into your responses (Write Neatly) Be sure to complete your data tables Be sure to put your units on your measurements. Ex vs grams Percent Change in Mass: Final Mass - Initial Mass x = _________ Initial Mass Example. The initial mass of a gummy bear is 5 grams. You put it in freshwater and check its final mass. You find that it is 8 grams. What is the percent change in mass? 8g-5g x 100= g x 100= 60% 5g g Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

3 Gummy Bear Exploration
Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

4 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Solute vs. Solvent A solution is composed of two parts: a solute and a solvent. Solute- substance that is dissolved within a solution. (being dissolved) Ex. Salt, Sugar Solvent- a substance that dissolves the solute (the dissolver) Ex. Water is the universal solvent. Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

5 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Examples Kool-Aid- What is/are the solute(s)? Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

6 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Solutes and Solvents Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

7 Gummy Bear Lab Exploration
Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

8 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Reflection: What did you learn from Day 1? Movement of Molecules, Osmosis, Diffusion, Equilibrium, Quantitative and Qualitative Data, Inertia, Raw Vs. Boiled Eggs, gummy bears, Solutions. Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

9 Day 2: Mrs. Dorcas Green and Ms. Arielle Darden
The Magic World of Biology and Chemistry Mentos Exploration Day 2: Mrs. Dorcas Green and Ms. Arielle Darden Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

What is a Geyser? A geyser is a hot spring that intermittently sends up fountain-like jets of water and steam into the air Source : Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

12 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Geysers and Mentos? Just as we modeled the process of Osmosis with gummy bears and potato cores, we are going to model the process that occurs with geysers. Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

13 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Mentos Investigation Experiment will be conducted in two parts: Part I: Which color of Mentos will produce the tallest geyser? Part II: Does changing the surface area of the Mentos affect the height of the geyser? Why might the experiment be done in two parts? Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

14 What is the surface area?
Definition of Surface area: The sum of all the areas of the shapes found within an object. In general, surface area is the outside part or uppermost layer of something. According to mathematicians, the surface area is the sum of all the areas of all the shapes that cover the surface of the object. Shapes include a square, cube, ‎rectangular prism, and ‎sphere or any polygon Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

15 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Uses for Surface Area Not only is surface area relevant to Math, it is also useful in the bodies of living organisms. For each slide, determine the advantage of increased surface area for the organism. Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

16 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Surface Area Example # 1 Why is it important that the small intestine has a large surface area? Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

17 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Surface Area Example # 2 How is increased surface area in the lungs important for survival? Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

18 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Surface Area Example # 3 Why do clam gills have increased surface area? Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

19 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Surface Area Example # 4 Why is increased surface area in plant roots and leaves important? Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

20 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Which leaf would produce the greatest amount of carbon dioxide in 60 seconds? Explain Leaf A Leaf B Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

21 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Question How can we increase the surface area of our Mentos? Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

22 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Mentos Investigation Generate your hypotheses to the following questions: Part I: Which color of Mentos will produce the tallest geyser? Part II: Does changing the surface area of the Mentos affect the height of the geyser? Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

23 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Look at your handouts…. There is a small portion of the procedure that you will utilize to get started. You will be working to design your own experiments today!!!!! Get Excited!!! We will be testing our hypotheses outside! Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS

24 Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
Lets Go! Dorcas Green, Instructional Coach and district 2 Co-director for NCSAS
