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? 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?

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

Understanding my accelerometer readings

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

Understanding my accelerometer readings Understanding my accelerometer readings Hi, I need some help with a project I was given at work. I am hoping someone here can be of assistance! I'm testing my accelerometer and the readings aren't really making sense. In my head, because it's the same weight every time I drop it and I drop from the same height each time, I thought I would get the same acceleration each time. The data I've gotten from it so far has shown otherwise. Sometimes the… Read more

Germ Invasion Hypothesis, and questions about how to identify which bacteria. Germ Invasion Hypothesis, and questions about how to identify which bacteria. Greetings, I am helping my son with his science fair project which begins this school year and finishes next school year. He picked the “germ invasion” project and we are having trouble figuring out a valid hypothesis. We understand the “If...Then” but we are having an issue of pinpointing what it should be. We are only using three… Read more
