Yeast makes heat rise, too
Independant variable: Amount of yeast on plant
Dependant variable: Heat produced
This was an experimant conducted by Spanish researchers and it was to find out if yeast helped to keep a plant warm. The scientists hypothesized that the yeast would create heat in the plant as it breaks down the sugars in the nectar. This is also true in producing things like bread with yeast. The experiment was conducted with a plant that was able to be regularly pollinated by a bee with yeast adhered to their body. There was also a plant that was protected from the invading bumblebees so as to see a difference in surrounding and internal air temperature for the plant. It turns out that the plant that was pollinated with yeast was recorded having a much higher and constant temperature than the plant with no yeast pollination.
I think the experiment could have been improved by using different types of plants, maybe fruits and vegetables. Fruits and vegetables used in the experiment could have determined a way of keeping them warm during cold snaps. For example, when Florida expiriences a cold snap and loses its stock of oranges, they could use yeast to pollinate the buds of the plant or other parts so death to the oranges may be prevented!

Independent Variable: the pigeons
Dependent Variable: the paintings
Scientists tested if pigeons could actually determine if the painting is good or bad art. They held various paintings up to the birds and they would peck at the painting if it was good. They would be awarded with food. Some were trained to peck at watercolor paintings and some were trained to peck at pastel paintings.

Pigeons Show Superior Self-Recognition Abilities to Three Year Old Humens
Independent variable: Species
Dependent variable: Time (sec.) it takes to recognize self
Scientists at Keio University have run some tests and now have data that a pigeon can recognize it-self in a video with a delay between 5-7 seconds. That is good considering that an average three year old human takes 2 seconds to recognize his/her self. Not bad for a bird brain.
I think that this was a ffun experiment, but it isn't getting us anywhere unless the bird can talk politics. This experiment could be improved by seeing how long it takes to recognize something besides it-self. That might be useful.

The Effect of Type of Music on Plant Growth
independent variable: type of music
dependent variable: plant growth
In the 1970s a well-known study performed by Dorothy Retallack at the Colorado Woman's College in Denver using the college's three Biotronic Control Chambers. There was one chamber where music would play daily for three hours, and for another it was played for eight hours a day. In the three hour chamber, the plants grew twice as large as the chamber with no music, but in the chamber where music was played for eight hours a day, the plants died within two weeks.
The types of music used were rock music and soothing music. Rock music made the plant made the plants small and unhealthy while the soothing music made them grow large and healthy. They actually grew towards the radio almost like it was the sun.
This was a good experiment because it gave both the chamber the exact same whereas some would have gotten more sunlight in others. The experiment could be improved by using more types of music like country. The could be many follow-ups to this experiment. For example, put plants in different conditions.
- the same plant types across the different conditions
- a variety of species, also across the different conditions
- strict controls on all other external factors, e.g. light, warmth, etc
- consistency of human interaction across the different conditions
- music vo,ume would need to be maintained at a consistent level

The Big Bang Experiment
In this experiment scientists are taking 2 proton beams and steering them in opposite direction. The beams will be traveling at the speed of light, if not close. They will be going more than 11,00 laps each second. Soon enough the two beams will collide along the track combining the protons. Scientists hope that the "Big Bang" with create a new subatomic particle.
IV:direction of proton particles
DV:speed of beams
C:a beams, number of protons
I think this experiment could be improved by adding more trails. This would help to get an more accurate conclusion.

Simple Test May Help Judge Concussion in Athletes
Research has shown that even a couple days after symptoms are gone from a concussion that reaction time is slower. The tests used to show this use computers and special software. So Eckner and his colleagues created an inexpensive way to test this. It consisted of an string with a weight attached to it. The person would do a test at the beginning of the season and then do the test after they have had a concussion. If the time was slower after the test at the beginning of the season then they are not ready to play. IV: Way concussion is tested DV: Results of test. I think this was an good experiment. This could be improved by doing more trials.

New study possibly links cognitive and motor delays with "flat head syndrome" in young babies
This experiment was about how "flat head syndrome", or postional plagiocephaly, affects the development of cognitive and motor skills in babies. The babies, ranging from 4 months to 12 months, were tested with minor tasks, such as finding hiddeen objects and rolling over. They were rated using the Bayley Scales of Infant Development III.
IV: babies diagnosed with flat head syndrome(1/2 of the group)
DV: lower scores in major muscle function tests and higher in other tests
The results of the experiment show that having flat head syndrome may effect a baby's development, but there is not a certainty of it.
This is experiment could have gone wrong n many ways. There is a chance that the babies said to have flat head syndrome may not actually have it. Also, the BSIDIII may not be completely reliable. A good way to improve this experiment would be to recheck the babies to make sure they have flat head syndrome. A follow-up experiment that would be suitable would be an experiment that tests the babies over the course of a few months, to see how much thaty have developed.

Hermit Crab Experiment
Independent Variable: desensitization from boat noises
Dependent Variable: how hermit crabs react to actual danger
Constants: boat noise, crabs
It shows that desensitization from boat noises does effect how quickly hermit crabs react to danger by reacting late.This experiment could be improved by adding different noises to see if the crabs have a sensitivity to the pitch of the noise or not.

The Effect of Music on Plants: www.wikianswers.com
IV:Music
DV:Growth of the Plants
Constants:Plant, Pot, Surrounding, Ext.
In this experiment you change to the music to see how it effects the growth of the plants around it. I think experiment is fine the way it is. I do not think it needs any changes. The conclusion is that it does effect the growth. If both plants in different rooms have the same amount of water and sunshine then it has to be the music or conversations around the plants. I think a good follow up experiment would be what type of music effects the plants the most.

chocolate lovers can reduce there risk of stroke
The experiment that I found was about the consuption of chcolate. Scientist researched that if you eat choclate every day then it can prevent you from dieing of a stroke. The Iv was the amount of chocolate comsumed. The DV was how many people died of a stroke. I feel that this experimen was not good because it is telling people to eat chocolate to stay alive. This may make people think that they can eat all they want and still be healthy and in many cases that will not work. Some changes can be made to this experiment by telling the people how much chcolate to consume. A follow up to this experiment would be the results of the experiment.

CELL PHONE DISTRACTION WHILE DRIVING IS A TWO WAY STREET
2/16/2010. Science News.
Scientists research shows that trying to tell a story while driving, despite safety issues, may be pointless anyway because you get it wrong. In this experiment, drivers and passengers were placed into a driving simulator, then each person heard a story through headphones, and finally told to retell each story to each other. The IV was that the story remained the same through each trail. The DV was that the location of the car. The first location was in an unmoving car. The second location was in a car on a straightaway. The third location was in a car that was going through intersections. Nearly 70% of the story elements were told correctly in an unmoving car. On Straightaways, 60% of the story elements were told correctly, and 50% on intersections. I thought this experiment was a good one because it shows that there is no point at risking your concentration when you will most likely get it wrong. I can't think of any way the experiment could be improved without danger. As far as follow-up experiments, I would do another experiment that changed the complexity of the story.

Sleepiness increases a risk for car accidents in teenagers. Feb 15, 2010. Science Daily.
A recent study shows that teenagers between the age of 18 and 21, who get a lack of sleep, double their risk of getting into a car accident. Researchers took 339 teenagers with a drivers license to conduct their study. They determined if the students got a lack of sleep by simple questions. The questions were about sleep habits, sleep disorders, any feeling of daytime sleepiness and more. Of the 339 students, 80 of them had been in accidents previous to the questioning. Of the 80, 56 percent of them admitted to being sleepy while driving. Only 35 percent of the remaining students, that had not been in an accident, admitted to being sleepy. The independent variable in this experiment would be the amount of sleep the student had before driving. The dependent variable would be if the student got in a car accident. I think this was a good experiment because it shows that if you are tired you are more likely to get into an accident. It also backs up what people think about drivers who don't give the road their full attention to the road, and what happens. This experiment could be improved by doing more detailed questioning on the people who got in the accident, by asking them for more a specific answer to their question. I think a good follow-up experiment would be the probability of getting into an accident if you are a teenager on the cell phone.

Study: Genetic Variation Programs Some People to Age Faster
The IV is Genetic Variation. The DV is the age of the peoples bodies. The title would be The Effect of Genetic Variation on the Age of People. In the study 3,000 people about 38% inherited the gene variation and were biologically 3 to 4 years older than those who didnt inherite the variation. This shows that some people are genetically programed to age faster than others. I thought this was a good experiment because it gives people a explination of why they age faster. To inprove this study they could have done it with younger peolpe because it would show more if they were older. The scientists concluded that people with the variation appeared 3 to 4 years older than those who didnt have the variation.
