Question : I' am a student of class 8th.I have got the topic 'Hydroelectricity' for my school exhibition.Can anyone please give me some ideas about making a hydroelectricity working model. Please Help. Thank you.

Answer : you can make a fan sort of thing which has a rod and copper wire on the rod in the form of a coil. the two ends of the coil can be attached to aluminium foil on the rod. make the fan move horizontally by pouring water from the top.if 2 wires are made to touch the aluuminium foil on the rod when the fan moves electricity is produced. to check for electricity, the wires touching the alluminum foil can be attached to a bulb.

Question : The state testing for 8th grade/history section: How i did: Math - perfect Language arts - about 95% Science - 86% History - 46% How much is the State testing for 8th grade History going to effect me?

Answer : In my state, 8th grade TCAP's (the state test) aren't very important, because we usually don't get the results back until first semester freshman year, when we're already about 1/4 of the way done with our classes. Instead, our SEVENTH grade TCAP scores make up 1/3 of the decision as to whether we take Honors, CP (average), or Fundamentals/Foundations in high school (Explore test and 8th grade teacher recommendations making up the other 2/3). But since you've already gotten back your state test results, maybe these will have some impact on what classes you'll be taking in high school. If you have done really well in your social studies classes this year (and in 6th and 7th grade), I wouldn't worry so much about one test... your teacher recommendations will likely have more impact than how you did on one test, because your teacher knows how hard you've been working all year and not just in one sitting.
