VDA#9 Potential

1) Consider the potential of these 3-D machines, what object would you print that could help the world? Why?

I would print coal lots of coal then we can change that coal into oil and we won't have to worry about gas prices going up or losing gas. We also wont worry about fuel and can give to other countries.


2) From a selfish standpoint, what one item would you print for yourself?  Why?


I would print a submrine/airplane/boat/car with a food maker and a robot that drives. It will also have a swimming pool/ jacusi and best of all it runs on oxygen and carbon dixode so you never run out of gas. and so it dosen't get dented its material is rubber.

1. Scientists predict that prune fingers may serve a purpose.  What purpose do they suggest prune fingers serve?

Scientists predict that prune fingers may serve a purpose for gripping wet objects.


2. Do you think that the study performed in England was a valid study?  Why or why not?

Yes I think that the study in England was valid because it proved that they grasped the wet objects faster.

3. How would you design an experiment to gather more data to support the suggestion that prune fingers serve a purpose?   (Be sure to include the number of people sampled, the independent and dependent variables and the duration or amount of time for your experiment.)

I could have 30 people and have 15 let them soak their hands in water for 15 minutes then let the other 15 people soak their hands in water for 5 minutes and see which grasps the objects faster. My independent variable is the peoples hands. and the dependent variable is the people, the water, and the objects

4. While scientists are attempting to determine the biological purpose for prune fingers, the article does not discuss why prune fingers happen in the first place.  What biological process allows for the skin on our hands and feet to turn wrinkly when submerged in water for long periods of time?   

The biological standpoint is called osmosis

vda #8

The economy in developed countries has an impact on CO2 emissions because the higher the economy the
more people are going to build factories and start businesses. Factories and manufacturing businesses will give CO2 in the smoke they give off. When the economy drops most businesses shut down decreasing the amount of CO2 in the air. Other than factory emissions cars, motorcycles, and trucks give off CO2 emissions. Yet in China and India coal the dirtiest and most carbon-intensive fossil fuel, has been found, and is growing fastest, with coal-related emissions.
