1. Bioengineering The development of technology in the fields of biology and medicine. Bioengineers have helped create new technology such as CT scanning Machine MRI scanner

2. Bioengineered products also help doctors treat diseases--ex. diabetes

3. Adaptive devices-- Aid the disabled and actually changes the user. Assistive devices-- Helps the disabled with their daily lives.

4. Lets take a closer look at the difference in these technologies! Assistive technology Adaptive technology crutches Contact lenses Hearing aid Cochlear implants Lasik Eye Surgery

5. Farmers always want to grow the best/most successful crops! Examples: 1. Crops that are resistant to disease. Engineers use bacteria to carry useful genes into plants. Helps to change a plant’s genetic make-up to protect them from diseases, frost and herbicides. What is an herbicide? Substance used to kill weeds! Gene – Tiny part of a cell that gives a living thing a certain trait.

6. 2. Plants are altered to stay fresh longer. Bioengineers found a way to make tomatoes ripen more quickly on the vine and lengthen their shelf life. 3. Plants may grow by using less water. 4. Crops that taste better, stay fresh longer, or are more nutritious. Can bioengineering plants be too successful? Resistance to herbicides—good and bad? Too much of a engineered plant—everyone suffers!

7. Gasoline for most cars and vehicles contain ethanol. A form of alcohol!

8. Ethanol is a biofuel—a fuel made of recently living things—not fossil fuels!

9. 1. Bioengineered bacteria help make ethanol from corn plants. Ethanol can be made in two ways: 2. Ethanol can also be made from plants with large amounts of vegetable oil -- soybeans.

10. 1.-- 2.-- 3.-- 4.-- 5.-- Name of device Assistive or Adaptive As each picture appears write the name of the device in the first column and whether it is assistive or adaptive in the second column.
