Section November 7‚ 2012 Abstract The effect of water and fertilizer on corn seedlings was examined. It was hypothesized before the experiment that enough water with sunlight and air should make the plants grow healthy. It has to do with photosynthesis. Fertilizer is also going to make the plants grow much faster; this is because of the nutrients in it. The experiment took about four to six weeks to complete; it took some days for the seed to germinate before planting. The corn was growing there were

Experiment Aim: To determine the acceleration of an object down an incline plane using various methods. Research Question: Is there a relationship between the angle θ of the incline and the acceleration down the plane? Equipment: * Ticker Timer (AC 50Hz ) * Incline (wood) * Meter ruler * Dynamic Trolley ( Mass: 380.55 ± 0.01g ) * Carbonated paper * Power Source (2W) * Data Logger * Motion Sensor * Tennis Ball Method for ticker tape experiment:

Purpose: To find the initial velocity of a marble leaving a ramp using time‚ range‚ and background information learned in class. Equipment: The equipment used in this experiment was a toy track and ramp‚ a small marble‚ multiple Physics textbooks‚ meter sticks‚ bright-colored cardstock‚ masking tape‚ sidewalk chalk‚ plastic bag and a cloth. Procedure: Our experimental values include the height that the marble would travel‚ y= 88.1 cm‚ and our ramp angle‚ θ= 44.0°. These independent variables

Purpose This experiment shows how different concentrations of acids and bases in a solution affect its pH level. When acids and bases are combined in a solution‚ they neutralize each other. This means that depending on the concentration of both acids and bases in a solution‚ the pH will vary. A neutral pH level is 7; anything below that level is known as an acidic solution‚ while anything above is known as a basic solution. To find out the pH‚ the solutions will be diluted and tested with different

Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

For my visual I did a stop motion animation explaining how Edmond Dantès evolves and changes throughout the story. Dantès started to evolve and change when he was sent to the Châtaeu D’If‚ so I started my video by describing what Dantès was like before he was sent to prison. For the video‚ I used both words and pictures to show how Dantès changes throughout the story. The beginning of the video started out with the quote‚ “He was a tall‚ slender young man‚ no more than twenty years old‚ with dark

Seth Dennison and Jenna Snyder John Bryan Psychology of Gender 104 10/31/2012 Psychological Gender Experiment For our psychological gender experiment we chose to focus on the topic of memory differences between genders. At first we wanted to figure out if one gender had a better memory than the other‚ but then we also wanted to observe whether or not their memory showed better results when the objects were related to their gender. Therefore‚ the hypothesis we constructed was: If

Parachute Experiment Aim: To investigate the effect of surface area on a performance (more the amount of a parachute better the performance) of a parachute. Hypothesis- More the amount of holes in a parachute‚ faster the rate of the fall. Variables: Dependent variable- The time it takes for the parachute to reach the ground. Control variables:Mass > Adding or subtracting mass from the load. > Clay can be molded around the load to increase mass. > Parts of the load can be cut off to decrease the

In 1687‚ Sir Isaac Newton published what are known today as Newton’s three laws of motion. If these laws didn’t exist‚ motion and life would not exist. His three laws are accurately relative to what "normal" speeds are on earth. Newton’s first law is most commonly referred to as the law of inertia. The law states that an object that is at rest will stay at rest unless an unbalanced force acts upon it‚ and vice-versa. If an object is moving and there is no force to move the object in a different
