PLANT GROWTH EXPERIMENT Numerous environmental variables influence plant growth. Three students each planted a seedling of the same genetic variety in the same type of container with equal amounts of soil from the same source. Their goal was to maximize their seedling’s growth by manipulating environmental conditions. Their data are shown below. Plant Seedling Mass (grams) Day 1 Day 30

Evaluation Evaluation Experiment one: This experiment was quite accurate‚ as when it is compared to the manufactures line which is on the same graph‚ we can see that this line is at most only 0.4? different form the manufactures line. This is a percentage difference of approximately 8%‚ using the formula: Difference ? original X 100 This shows that the results were good‚ as 8% is a very small margin of error. The error bars on the graph show that the most inaccurate result was the 60cm result

self-regulation is emerged. So‚ where does it all begin? Childhood. Pre-school is a great place to start teaching self-regulation. An experiment that I believe to be a useful demonstration of educating children on their self-regulation is group games that promote leadership skills. Materials Needed for Experiment: • Pilot’s hats Procedure To begin this experiment the marshmallow test must be administered to the kids and the results must be recorded. We then separate the kids into two different

Ballistic pendulum designed experiment Aim: to investigate how the mass of the projectile affects distance on the motion of a wooden block it strikes Hypothesis: the heavier the projectile the further the distance will be covered by the wooden block Variables: variables Identification Manipulation Independent Mass of projectile The four different masses will be used in different combinations Dependent distance Measured using tape measure Controlled 1. Height of retort stand 2. Release angle

Surface Tension Steven Brignol Dr. Payne September 15 Introduction: Water’s ability to stick to itself is surface tension. In this lab we were able to measure and detect surface tension by dropping water‚ drop by drop‚ onto a penny. The quantity of droplets that fit on the penny was impressive. Hypothesis: The detergent will thicken the water making a tighter surface tension. Prediction: If soap increased the surface tension‚ then expansion will happen. Materials: (1) Pipette (2) Water

I don’t think this experiment should be replicated today. The reason being is that the Generation we have today has a different mindset and that the experiment is unethical in my view. In 1961‚ Milgram was able to make the participants agree with the experiment. These results led to people trying out these trails because the participants knew the shock would be painful but not dangerous. With that being said‚ it shows you the mindset of the people during that time. People were laid back and were

High fructose corn syrup is a well-known food additive that is listed as a primary ingredient in most food products. It is very common is most of the population’s daily diet and it is ordinary to find it in our foods. People are constantly advised to minimize the consumption of it because of the variety of negative health effects it causes from in-taking too much of this factor. But what really is high fructose corn syrup? What foods is it found in? Is it really as unhealthy as it is claimed to be

the experiment‚ the observational study and the survey. An experiment is a scientific method in which data are collected to be tested to prove a hypothesis using either independent variables in a closed environment or dependent variables in an opened environment. There are two types of experiment‚ the laboratory experiment that is as its name suggests conducted in laboratory and the field experiment conducted in a natural environment. The advocates of positivism support the use of experiment due

ingredients in processed foods‚ and unfortunately one of the most popular ingredients‚ is high fructose corn syrup. High fructose corn syrup is produced from corn starch; it also includes predominately fructose and glucose. It has higher proportions of fructose than regular corn syrup‚ usually forty-two or fifty-five percent more‚ with the remaining sugars being glucose and other sugars. High fructose corn syrup is a sweetener that can be found in thousands of food and beverages throughout the United States

There were 3 main experiments that were conducted in the 19th century. The first experiment was conducted in 1928 by Frederick Griffiths. He was able to establish that there is a substance being transmitted from one generation to another. For this experiment Griffiths used two types of pneumococcus bacteria (the bacteria that is responsible for causing pneumonia). He used the smooth strain (S) which had an outer capsule that acts as a protective shield from the host’s immune system and rough strain
