1. Hints on PowerPoint 1. Do not use fancy transitions such as flying in or letters dancing. 2. Do not use fancy backgrounds- keep it as plain as possible. 3. Use the same background for all slides in the presentation. Note: Simple background slides 2&3 are samples. Students should have a slide to coincide with each slide displayed except first three slides and they can use one picture of several

2. Presentation skills 1. Students - dress casual, nothing glittering or flashy 2. Introduce yourself and tell the name of your school 3. Tell why you chose your project ( example, my mother had a tooth pulled and the doctor asked her to place a teabag in her mouth to help stop the bleeding) 4. Good eye contract – talk from slides – do not read and keep procedure short on slide, expound as you talk it out - you have only 10 minutes to present.

3. Which Brand Of Teabags Helps Stop The Bleeding After Getting A Tooth Pulled? by Student Name Rochelle Middle School Slide # 1

4. In this investigation, different types of tea were used as a medium for blood clotting. The purpose of this research was to determine which type of tea will clot blood the best. Three different mediums were used to clot blood. My results show that Lipton tea is more effective in helping clot blood Abstract Sample of plain background

5. Hypothesis If Luzianne teabags, Tetley and Lipton teabags are tested for their ability to clot blood, then Tetley and will work better Lipton teabags.. Sample of plain background

6. Abstract In this investigation, different types of tea were used as a medium for blood clotting. The purpose of this research was to determine which type of tea will clot blood the best. Three different mediums were used to clot blood. My results show that Lipton tea is more effective in helping clot blood. Slide # 2

7. Hypothesis If Luzianne teabags, Tetley and Lipton teabags are tested for their ability to clot blood, then Tetley and will work better Lipton teabags..

8. Control The blood placed in plain water served as the control.

9. Variables The independent variable is the brand of tea. The dependent variable is the amount of clotting that occurred.

10. Materials 1) Condiment cups 2) Artificial Blood 3) Teabags 4) Syringe 5) Water

12. Procedure –three condiment cups, add 4ml –Measure artificial blood in each cup. –Obtain three brands of tea –Wet each of bag of tea with cold water. –Place the tea bag in petri dish –Wait for ten minutes to get results. –Repeat the procedure four times

13. Measuring the spread of blood

15. Date Manipulation Finding the mean for each trial Mean = Σfx n Control =Σ (8 +5+ 9 + 9) 4 Mean = 7.75

16. Date Manipulation Finding the mean for each trial Mean = Σfx= (sum of frequency of x n Average (same as mean) Average = Trial 1 + trial2 + trial3+ trial 4 4 Student can use either equation for the average Mean is the same as the average; however, when competing you want to use bigger terms if possible

18. Comparing ability of tea to clot blood

19. Blood Clotting Graph

20. Conclusion My results show that Lipton tea is more effective in helping clot blood. Luzianne was the second most effective. The trends show that when tea was added to the blood, the blood spread across the petri dish in a narrow band about 1.5- 2 cm wide. Based on the measurements it can be determined that Lipton clots blood the best. The appearance of the blood was grainy in the Lipton and Luzianne as compared to the control and Tetley tea. My hypothesis was correct Lipton tea worked best.

21. Application This project will help people stop the bleeding in their mouth when they get their teeth pulled. It will also be much cheaper than buying medicine at the store.
