Ask an Expert Topic Forum: Careers in Science

Career in science - what advice would you share? Career in science - what advice would you share? This might sound a bit weird but I am genuinely interested in the following. Background information (the reason why I ask) I will be giving a ~ten minute presentation to just-have-finished PhD students in Germany about career options. The students want to know about possible career options. Most of these students will be in natural sciences. So I am interested in your opinion even though you… Read more

When exposed to carbonic acid in rainwater, limestone can deteriorate and weaken. What affect does this process have on the landforms of Texas hill country? Answer Choices: -leads to contamination of groundwater -strong Texas clay sits under limestone, so the weakened limestone does not affect landforms -leads to the formation of underground caves -leads to increased… Read more

Dice Rolling Probability

Ask an Expert Topic Forum: Grades 9-12: Physical Science

Dice Rolling Probability Dice Rolling Probability I am doing a science fair project on dice rolling probability. I have a D-6 (six sided dice) and a D-12 (twelve sided dice). I rolled the D-6 100 times with my left hand, my right hand, and then cupped in both. I did the same with the D-12. After recording the numbers and then adding up the sums of all the added rolls, I repeated the process but with rolling both die at the same time. I am trying to record the probability of rolling a 6 with… Read more

What do I name these units? What do I name these units? I am having an issue understanding how to convert my results from the electrolyte challenge to the information needed in the project. The information I have is inconsistent with the data others got, but I think I know why. Some of my solutions were expired products. I have discussed it with the teacher. She said to keep the data but explain why I feel the results may be incorrect. At any rate, these were my findings. Can you tell me… Read more

How can you expect me to believe when you have no evidence?

Ask an Expert Topic Forum: Grades 6-8: Physical Science

How can you expect me to believe when you have no evidence? How can you expect me to believe when you have no evidence? The law of conservation of angular momentum cannot be confirmed in variable radii system. We have been told that "it spins faster", but that is not good enough. It does not "spin faster" enough. A ball on a string does not accelerate like a Ferrari engine. How can it be conserved if we cannot confirm it? Re: How can you expect me to believe when you have no… Read more
