Abstract The purpose of this lab was to see if radiation has an effect on the cultivated radish seeds that we used. From the observed data that we collected‚ we were able to conclude that when seeds are exposed to radiation‚ it affects how they grow‚ if there is any growth at all. Introduction Radiation is an important environmental abiotic factor for plants‚ and one small section of the electromagnetic radiation spectrum‚ is called the Photosynthetically Active Radiation (PAR)‚ provides

STATISTICS PROJECT: Hypothesis Testing See my comments in red. Scoring last page. INTRODUCTION My topic is the average tuition cost of a 4-yr. public college. Since I will soon be transferring to a 4-yr. college‚ I thought this topic would be perfect. "The College Board" says that the average tuition cost of college is $5836 per year. I will be researching online the costs of different public colleges to test this claim. I will be using the T-test for a mean‚ since my sample is going to be less

long enough (thanks to a sideways clipped bang extension) to take a decent photo of my finished hat (above) so that I could complete the post. I’m not entirely sure what you would call this style of hat exactly. I know that it resembles a “halo hat”‚ but a true halo hat has a band almost like a huge beret‚ so that’s not it. I’m going to go with “1940’s large brim hat”. I became inspired to try this out when I was at the thrift store a couple of weeks ago and saw a hat partially sticking out from under

Animal testing has been around since Aristotle’s time. Since then animal testing really took off for medical uses in the early 19th century. Since then laws have been put on animal testing when congress passed the Food‚ Drug‚ and Cosmetic Act in 1938. It is estimated that 26 million animals are abused in animal testing annually. Some of the causes include animal testing cannot stop or we would have no way of knowing if something is safe or not‚ assuming that animals and humans have the same DNA‚

The Flaws With Animal Testing Every product we own‚ from makeup to medicine‚ has to be tested on something or someone before it can be placed on the market to be sold. Most testing for products is done on animals because it is seen as more humane than testing on humans. Animals are viewed as below us‚ and because of that‚ their lives do not matter. That is a lie we tell ourselves to make it seem like what is being done to innocent animals is just. In reality‚ testing on animals does much more harm

The Side Effects of Standardized Testing You would not give your kids unneeded pills that had side effects of limited creativity‚ stress‚ or anxiety‚ so why give them unneeded tests that do the same? In a peer-reviewed journal‚ 2015 Schooling In America Survey‚ it is stated that 60% of Americans believe negative thoughts about K-12 education‚ that it has gotten off the wrong track (DiPerna). A large number of parents‚ students‚ and teachers all believe that education is not on the right track. Why

Is it the discovery of which perfume smells appealing or which brand of shampoo is the cheapest? Or does the consumer consider whether animals suffered during testing to ensure that the purchased shampoo or perfume was safe for human use? My guess is probably not. Little does our society recognize that many drugs‚ cosmetic items‚ and household chemicals have been rigorously

Have you ever wondered what is the story behind products and cosmetics? Well‚ today you are going to find out what happens. Animals testing is a very favored way to test to see if a product or cosmetic works how it is supposed to on humans. Over 100 million animals die each year because of animal testing alone‚ the animals are burned‚ crippled‚ poisoned‚ and abused. This sounds like a cruel thing that should not be legal‚ but it totally is. In only 50 experiments‚ about 12‚000 animals have to
