Luis Berrios 3/7/12 Physics Honors B Block Egg Drop Project For this project‚ I made a capsule for an egg that is to be dropped from about twenty feet. This capsule that I made was not what I was thinking at first but when I started to build it‚ I saw that this capsule would hold better than the one that I was thinking which was a triangular capsule with the egg in the middle but I saw later one that the egg would break if it hit one of the flat sides. The capsule is a cube that is made out

Effects of Cell Phone Advertising for the last 20 years This paper sets out to explore the correlation between cell phone advertising and the effects it has had on our society. I will provide evidence that advertising has transformed our social norms in regards to cell phone usage. First topic of discussion will be on the history of the cell phone‚ discussing the advances they have made in the last 20 years. Next will be the discussion of advertising as a separate entity‚ and then confer advertising

CELL THEORY – STEM CELLS Stem cells are a large focus of study in today’s biomedical world. “They are cells that exist in an undifferentiated state‚ and transform into differing tissue types depending on what the cells surrounding them are‚“ (National Institute of Health‚ 2012). Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition‚ they also serve as an internal repair mechanism inside many tissues‚ dividing without

Aim: To investigate how effect of Detergent Concentration (cont.) has on Membrane permeability of Beetroot cells. Hypothesis: I predict that as detergent concentration increases‚ the solution will become less clear‚ plus mass increases. The increases in mass will indicate that the water potential of the Beetroot cell is lower than that of the surrounding sucrose solution. The Beetroot discs will become flaccid and decrease in mass if the water potential of the surrounding solution is lower than

bullying About a week ago I was assigned a film project on bullying and peer pressure. What my group did was a recreation of the breakfast club. Although I’ve never seen the movie I was very excited to start. The project really did help me learn the harmful effects of bullying and peer pressure. One part that showed me about bullying is when one of the main characters‚ Sophia‚ confesses to the group that she told everyone about a girl’s crush through Instagram. That scene made

1 mark) 2. Which hypothesis can be tested using the t-test? A. The difference in variation between two samples is not significant. B. The difference between observed values and expected values is not significant. C. The change in one variable is not correlated with a change in another variable. D. The difference between the means in two samples is not significant. (Total 1 mark) 3. The lengths of a sample of tiger canines were measured. 68% of the lengths fell within a range between 15 mm and

Stem cells -are biological cells found in all multi cellularorganisms‚ that can divide (throughmitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells. In mammals‚ there are two broad types of stem cells: embryonic stem cells‚ which are isolated from the inner cell mass of blastocysts‚ and adult stem cells‚ which are found in various tissues. In adult organisms‚ stem cells and progenitor cells act as a repair system for the body‚ replenishing

Experiment with a Shell-Less Egg After Three days of Testing Methods with Water and Corn Syrup Lisa July 1‚ 2013 Purpose To use the properties of diffusion and osmosis to see the effects of either corn syrup or water on a shell-less raw egg over a three day period. While looking to see the effects of these liquids on the raw egg‚ one can also apply the properties of hypotonic‚ hypertonic‚ and isotonic solutions. Introduction Cells have an outer covering called the cell membrane. The membrane is selectively

“In what way can a drop an egg off of a building without it cracking?” when I first asked this question a believed that it would be an easy task. I however‚ was very wrong. As I came up with ideas Mr.Billy kept on turning them down saying “that isn’t allowed.”‚ but in my defence most of the things that were not allowed were not written in the rules. In the end our design was very successful in safely delivering the egg to the ground. With changes it probably could have been improved‚ I was happy
