  1. Science Fair Project Type your project title here Your name Your teacher’s name Your school

  2. Statement of the Problem We were trying to extract our own DNA.

  3. Project Overview

  4. Research Summarize your research here in three to five bullet points: • 1st bullet point • 2nd bullet point • 3rd bullet point • 4th bullet point • Note: Soap breaks down the cell membranes, releasing the DNA.

  5. Variables • Controlled variables: These are the things that are kept the same throughout your experiments. • Independent variable: The one variable that you purposely change and test. • Dependent variable: The measure of change observed because of the independent variable. It is important to decide how you are going to measure the change.

  6. Hypothesis Based on the research you have done, you will be writing an answer or solution – your best educated guess – to your question. Make sure you write down your hypothesis before you begin your experiment.

  7. Materials • bottled water,1liter • clear dish soap, • Blue food coloring, 6 drops • table salt, 1 tablespoon • 70% isopropyl alcohol,100ml, • Beaker • Water bottle • cup • Stir stick • Measuring spoon

  8. Procedure • Step 1: We mixed 1000 ml drinking water with 1 tbsp salt • Step 2: We Stirred until salt is dissolved. Then transfer 3 tbsp of salt water into a clear cup. • Step 3: Gargle the salt water for 1 minute. • Step 4: Spit the water back into the cup. Now our cheek cells are suspended in the salt water. • Step 5: Gently stir the salt water with one drop of soap. (Avoid bubbles as much as possible). • Step 6: In a separate cup, mix 100 ml isopropyl alcohol and 6 drops of food coloring. • Step 7: Tilt the salt water cup and gently pour the alcohol so that it forms a layer on top (about 2 cm thick). • Step 8: Wait about 2.5 minutes. we should see white clumps and strings forming.

  9. Data/Observations • I was able to see my DNA • I was n

  10. Conclusion Type a brief summary here of what you discovered based on the results of your experiments. You need to indicate whether or not the data supports the hypothesis and explain why or why not.

  11. Works Cited Be sure to include print and electronic sources and put them in alphabetical order.
