DR PATRICIA BATH Dr. Patricia Bath was an American ophthalmologist (eye surgeon) and humanitarian. She was the inventor of laser cataract surgery. Her invention was called Laserphaco Probe. Her device, the Laserphaco Probe, Patricia Bath was created a less painful and more precise the first African treatment of cataracts. Before her American to invention, surgery was very risky, time consuming, and also was very expensive. complete a residency in While at Columbia University, she ophthalmology discovered that African Americans were twice as likely to suffer from blindness and the first than other races, and eight times more African likely to develop glaucoma.

Secret codes are similar to science investigations. They contain both direct and indirect evidence to help you draw conclusions and solve the code! When you analyze the data from an investigation, you need to look at all the evidence. Sometimes the evidence is very clear and direct or observable and measurable. This is called direct evidence. Evidence that is not as clear and measurable is called indirect evidence. This type of evidence you have to infer from what your data tells you or what you can see but can not actually measure. Both types of evidence are used to draw conclusions and determine whether you have answered your question or proved your hypothesis or solved your code. www.littlebinsforlittlehands.com DR PATRICIA BATH Use your decoder ring to reveal a quote by Dr Patricia Bath. ** Turn your coder so the letter A lines up with 6. 25 13 10 6 7 14 17 14 25 4 25 20 23 10 24 25 20 23 10 24 14 12 13 25 1424 25 13 10 26 17 25 14 18 6 25 10 . 23 10 2 6 23 9 www.littlebinsforlittlehands.com E | TOP SE OD CR C E T T E S R C C I E E S N | T I T S S T I | T S N E E C I R C S E T T E C O R D C E E | S P T O DR PATRICIA BATH Try to find all the words listed in the list below.
