INTRODUCTION
Plants can sense many factors around them such as temperature changes, harsh winds and even the human touch, but there are continuous debates among scientists about whether or not plants can hear or respond to sound stimuli.
Plants have no specialised structures like most living organisms, but many studies have found that plants can recognise the sound of predators through tiny vibrations in their leaves. It is similar to how the human immune system works; the first experience with insects or bacteria can help plants defend themselves better in future attacks by the same predator. So, a plant might not respond to a hungry caterpillar the first time it encounters one, but the next time it encounters one, the plant will increase

This sample would be the control of the experiment
Secondary Research
• Find information about how plants interpret sound on the internet and in books.
• Analyse data collected by other students or scientists.
THE EXPERIMENT
Hypothesis:
Playing classical music to plants everyday will increase their growth, thus showing that plants can actually respond to sound.
Variables
Controlled variables:
• The environment- both containers were kept in the same room. The plant that was not being grown to classical music was moved to a room with the same conditions when classical music had to be played.
• The amount of water- water was measured using a syringe.
• The size of the beans- the size of the beans was compared to each other to get six beans that were roughly the same size.
• The size of the containers- two similar glass jars were chosen.
Independent variable:
• The amount of music played to the beans.
Dependent variable:
• The reaction of the beans in the absence or presence of music.
Apparatus
• Dry beans x6
• Syringe
• Two containers that are equal in size
• Cotton wool
• Water
• Classical music (downloaded)
• Music source (blue tooth speaker connected to phone)
• Camera
Method
Identify the independent Variable Size of the tablet Identify the dependent Variable Reaction time List the controlled variables The solution (water), temperature, volume of water (200 mls) The amount of Alka- Seltzer How will the dependent variables be measured A stop watch will be started as the pieces of Alka-Seltzer are dropped into 200ml of room temperture water Describe the expected results if the hypothesis is true The 3 smaller pieces of Alka Seltzer will dissolve quicker than the ½ tablet .
The data observed and recorded in this lab shows that the concentration of miracle gro’ does affect the growth rate and germination speed of black eyed peas. The data is shown through two graphs and two data tables. The control group in this experiment is the seeds with a 0% concentration of miracle gro’, therefore the seeds with just water. The experimental groups are different concentrations of miracle gro’ including a 10%, 15%, 20%, 25%, and 30% concentration. The variable in this experiment is the amount/concentration of miracle gro’.
a biology class wants to perform an experiment to investigate the effect of different colors of light of green, yellow, red and clear cellophane and plant three seeds in each one. What part do the three seeds experiment? A,Confounding variables B.Independent variables C.Control variables D.Dependent variables 40. Iodine directly helps which of the following glands to function properly?
Brian Eno once said, “All music has political dimensions because it suggests a way of being.” Every song has a distinctive meaning to it. Political music can often affect the public policy process. The public policy process includes: recognition and definition, agenda setting, policy adoption, budgeting, implementation, evaluation, and adjustment or termination. The making of a public policy begins with a problem, which is similar to most songs.
Question 1: Evaluate other 's work: There are limitations/doubts about Mrs. Leonardos ' conclusion. In the data ,it shows two different densities which might mean she is using two different type of clay and it shows this is not a controlled experiment since in the background it states "... she begins to wonder if each differently sized piece has the same density. " So if she is trying to see if the "size" of a clay will affect the density so changing two factor results in a uncontrolled experiment.
For example, if rap music is played to a pea plant then the pea plant will grow exceptionally. Then, Sandy should have used identical pea plant seeds in the same soil, watered the same amount, and given the same amount of sunlight. The only varying factor in her experiment should have been the rap music being played
The mimosa is a prime subject for this testing as its reflex behavior is observably quick enough to document the reactions; upon contact, the fernlike leaves of the plant recoil from the touch. This behavior is likely used as a defense mechanism to scare off insects but in the study, it was used to measure the plants’ responses and help to conclude if they were adapting to the conditions. The experiment Gagliano conducted tested nearly five dozen mimosa plants’ reactions to being dropped a small distance every few seconds. Gagliano noted how the organisms initially reacted by folding up but after only a few drops, the leaves began to reopen. The ecologist took this as evidence that the mimosa plants recognized that there was no harm in this particular movement and “had concluded that the stimulus could be safely ignored” (Pollan).
VARIABLES: There are independent variables, dependent variables, and controls. the one that is being tested and the one that is the inconsistent variable in the Independent variable like the volume and surface area of the agar cubes. The variable that is kept consistent is the dependent variable such as the percentage of diffusion of pigment in the agar cubes. The constant variable is the features of the experiment that is kept the same throughout the entire experiment such as, the amount of time the agar cubes are left in the beaker and the amount of acid in the beaker.
Because of the numerous amount of trees near the tree line, there is a greater probability that the trees will cast a shadow over the wild flowers and prevent the flower from absorbing potential sunlight which would delay or prevent growth. Wild flowers that occupy the open area in the middle of the old field, however, do have shadows cast upon them and can therefore absorb more sunlight compare to the shaded flowers. Other experimentations performed show support of the hypothesis that was formed in this lab. It has been shown that the competition for light has a strong influence on the growth of plants (Coomes & Allen, 2007).
In this experiment, there are several factors that can affect
The dependent variable, which is the time taken for the empty muffin paper cup to touch the ground (immediately after it was dropped). This will be measured using a stopwatch, which will start when the paper cup is dropped, and stopped when the paper cup touches the ground. This will be done on table, preferably inside a science laboratory. (The table will be parallel to the muffin paper cup).
The very first classical concert that I went to was held on Wednesday, October 14, 2015 at 7:30 p.m. The performers were known as The Wind Ensemble from the San Jose State University School of Music and Dance Department. The Wind Ensemble is made of students who are experts in playing instruments such as brass, percussion, and woodwind. Some of the pieces performed at this concert were: Lift Off, Be Though My Vision, and Molly on the Shore. All of these pieces of classical music had different styles and sounds.
Music therapy interventions are effective as music stimulates parts of the brain occupied by creativity. It has stood the test of time to confirm that humans respond to music. This makes sense as music stimulates more parts of the brain than any other human function. Which is why music has so much potential in its ability to affect the brain and change the way people think. Musicians understand how different sounds play off each other and the effect that it has on the body at a deep level.
Last year, Novi High School decided to cut budgets from the Performing Art department, which includes various music programs such as the Jazz Band, Orchestra, Choir, and many more, to raise fundings for the athletic programs. Novi High School is not the only school that neglect music programs. However, the importance of music programs should be valued more because of their positive influences over students’ life. One important lesson students learn from music programs in school is the importance of collaborating with others. When students are playing or singing with other fellow musicians, they are working with fifty or so students to create a successful performance.
Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
