Research Paper Marissa Chudy
Several students are doing Science Fair projects at Woodstock Middle School and I am one of the seventh grade students. The topic I shall be doing is on how bridge structure affects the weight bearing capacity. I chose this specific topic to guide bridge builders in the right direction on what bridge is safest for public use. The key topics I plan to research on include the following: Beam, Warren Truss, suspension, cable-stayed, and arch bridges. I shall use the scientific method to guide me through this process. Like every other science project, mine starts with a question. How does bridge structure affect the weight bearing capacity? is the question. If I change the bridge structure on the most popular bridges, then those specific bridges will be capable of holding longer and hold larger amounts of weight. is the hypothesis. The three types of variables used are independent, dependent, and control variables. These variables include the location of the bridge, the bucket, the amount of water, the supplies, and the climate I experiment in. There are multiple items and steps to fully complete the experiment. My materials include the following: Graph paper, 200 regular Popsicle sticks, wire cutters, wood glue, 100 cotton swabs, 72 medium and small binder clips, one-half inch width clear tape, masking tape, gram balance, loading block
Equipment- 250mL beaker, 125mL Erlenmeyer flask, cardboard square, chemical scoop, metric ruler, lab countertop, rubber stoppers, safety goggles, lab apron
The materials that were used/needed in this experiment were a penny, water, soap, rubbing alcohol, a pipet, and a beaker.
1) The materials: cup, gummy bear, triple beam balance, water, metric ruler, and pencil were utilized for the experiment.
The materials used during the experiment included three plastic cups, three gummy bears, masking tape, marker, balance, calculator, tray, one plastic spoon, a measurement tray, and a ruler. The three plastic cups were used to hold the tap water, salt water, and sugar water. The masking tape and marker were used to label each cup with the
Mrs. Collins addressed the 6th grade Science class with the most uplifting positive attitude that anyone could have. Every day she came to class she always had candy and snacks sitting on her desk for students to enjoy when they were on their best behavior or if students participated. Everyone insisted on behaving and participating just so they could get a treat. One day Mrs. Collins called on a young boy whose name is Mark, but everyone else addressed him by meanie mark. Mrs. Collins asked Mark if he would like to come to the front of the class and demonstrate the Mentos and coca cola project. Mark did not say anything the first time. The second time she asked he murmured something, no one could not hear what he said. He set in the far back left corner of the classroom by himself. No one wanted to sit next to Mark for he intimidated everyone that he came across. He always wore black and he never spoke to anyone no matter how nice they were and he always had his head down. Mark was a loner. Furthermore

BEFORE CONDUCTING THE EXPERIMENT - You should already have submitted to your teacher an EXCELLENT Investigation Design that included:
According to article, “In a high-quality program, there is a focus on developing healthy and strong human relationships (p. 40). The program takes place in Condor Elementary School. They used the cafeteria to give them a snack, and make Woven Baskets for children in Protective Services. They had plenty of space to do their project, there were many tables and benches for them to openly do their work, as well as move around. They had a 12-child/2-teacher ratio, which facilitates the supervision of the children. They provided all the material (had plenty of them). They also had board games, plenty of art supplies, and books. In addition, they were provided with outdoor physical activities.
The experimental procedures for Lab 2 were provided on Blackboard labelled as “Pre-Lab 2: Techniques & Measurement”.
I do science fair because I love to invent. From designing, to programming and troubleshooting, I enjoy making new things. When I fix a strenuous bug, I feel accomplished. The tougher the bug is, more the satisfaction I get when I resolve it.
If one were to do this lab with actual chemicals they would need magnesium (s), a Bunsen burner, a crucible, a scale, a thermometer, a pressure gauge, an Erlenmeyer flask, a gas syringe, copper (II) carbonate hydroxide hydrate (s), 2 beakers, HCl (l), zinc (s), NaOH (l), and NiCl2 (l). Procedure: Before
My investigative question is does microwaved water stunt plant growth? I was interested in learning more about this topic because I wanted to know if microwaves can put chemicals in your food causing you to not get all of the nutrients from the food. The purpose of my experiment is to see if water set to a boil on the stove, water set to a boil in the microwave, or water from both the microwave and stove will make plants grow more, also to see if the microwave puts bad chemicals into your food. My independent variable is the type of water used. My dependant variable is the height of the plant. My hypothesis is, if plants are grown with microwaved water then they will not grow as much as plants grown with water heated from the stove.
Safety Goggles, 50 mL granulated cylinder, 10 mL granulated cylinder, glass vial with stopper and pipet, thermometer, plastic shoe box (tub), catalase from chicken liver, pH paper 0.1M NaOH, 3% Hydrogen Peroxide, tweezers, filter paper disks.
The Materials that were used to measure the experiment where a pen and paper to record the reactions of the subjects being tested, and the subjects themselves.
The scientific question of the project was, Does the size of a tire affect the bike’s speed? The hypothesis was , If the smaller tires were used, then the bike would go faster. The important procedures were: Make sure all equipment is ready. Test the standard wheel of 1 rotation or pedal a second to ride to the finish line. Test smaller and bigger wheels. Record data and have at least 3 trials. Record the data on a piece of paper and compare results to your hypothesis. The Independent variable is the size of the wheel on the bike. The Dependent variable is the standard wheel or tire on the bike. The control group was the bike’s speed and the standard wheel or tire. The Experimental group is the other tires or wheels being tested on the bike. The control variables were the rate of pedaling , the same bike model was used, and the same distance for
