DESIGN PSOW Ajit Rajendran 13H To Determine the Time Taken for a muffin paper cup to reach the ground, while Changing the Height of each experiment Introduction: In this experiment the aim is to determine the time taken for an empty muffin paper cup to reach the ground, by changing the height the empty cup is dropped from. Both variable mentioned are going to measured (height and time taken), when conducting the experiment. In order to have a fair experiment, certain factors will be kept the same throughout the experiment: the same paper cup will be used, the dimensions of the paper cup will be constant (where external factors do not affect the shape), the method in which the paper cup will be dropped. There will be a trend of the time …show more content…
Record the readings for the time taken, for the particular height (the paper cup was dropped from). Repeat this process (using the same equipment), by varying the height of paper cup from the ground (with a specific difference in height, in each experiment). The independent variable, which is the height the empty muffin paper cup is dropped from, will start at 1 metre and the increase in height will be 0.5 m in each experiment. The use of the clamp stand is effective in this experiment because it will always control or keep constant, the height in which the paper cup is dropped from, unlike somebody dropping the paper cup using his/her hands. 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). Thus the measurements will repeat for each experiment, where the paper cup’s height from the ground varies in each
Our dependant variable in this experiment was the dissolved oxygen parts per million in each sample. We recorded this data on the white board back in our classroom, writing down the specific parts per million that we found in the water. The variables that were the same for all
The data from the laboratory experiment are shown in Table 1. Table 1: Time taken for the cat to escape from the puzzle box Attempt Time taken for the cat to escape from the puzzle box (seconds) 1. 63 2. 60 3. 45 4.
In almost every experiment, there’s an independent and dependent variable, a constant, and a control group. The independent variable in this lab was the coins. The dependent variable was the density. The constant was the amount of water. In this lab, there was no control group .
Repeat these steps three times, then solve and record the average height. After dropping ball 1 from 2 meters, use
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 .
I wanted to start a club about cups. Ever since I was 7 years old I wanted to start a club for cupstacking and teach others this wonderful skill. Cupstacking involved stacking cups in sequences while also trying to get the fastest time possible. It started in the summer of 2015 and I taught summer camp children cupstacking just for fun. Then I started thinking, “What if I started a cupstacking club in my old school?”
Maybe it is just a trend? Even if considered a trend, it’s not a good
The variable for each experiment will be the brand of toilet paper otherwise, for each experiment everything else will be
What is the Marshmallow Experiment and what does it explain? The marshmallow experiment is a simple procedure. The researcher brought the child to the room and told them about the experiment. The researcher would leave the room for about 15 minutes, but he wouldn’t tell the child.
Data Analysis Does the type of ball affect how far it rolls when rolled down a ramp? The hypothesis for this experiment was “If the different types of balls are rolled down a ramp, then the soccer ball will roll the farthest.” The independent variable, the variable that was intentionally changed, were the types of balls. The distance each ball rolled is the dependent variable. The experimental group includes the soccer ball, the basketball, the tennis ball, the golf ball, the marble, the baseball, and the ping pong ball.
8) Explain how each experiment type (question 7) differs from the
I will also watch how slow the cup went. I want the cup to go down the ramp fast, but not too fast. If the cup rolls down without a problem, then I know that it was a good ramp. If the ramp rolls down to fast, then I know it was too high. If the ramp rolls down to slow or not at all I know it was too
Place the the beaker onto a hot plate that is on a low heat setting (about setting 3). Every 5 minutes for 20 minutes, measure the circumference of the balloon and record it in Data Table A. You can measure the circumference of the balloon by looping a piece of string around it then using a ruler to measure the string’s length. Record the data in the data
In the experiment, a magician placed down and shuffled three cups on the table with one cup containing a ball. While the cups were being shuffled,
Samuel colt was one of the first to make a modernized handgun. It was a revolver which means it didnt need reloaded after every shot "How does a gun work"Chris bast. He went to india to get some help with his ideas and came back with 3 models and many prototypes. All were very complicated and he got a patent "How does a gun work" Chris bast. The colt python was considered to be the most well known handgun.
