During the bounce test, the ball may have been released from different points. Although it was supposed to be released from its bottom, human error may have compromised the precision of this measurement. To improve the design of the bounce test, the ball’s bottom point should be marked, and the ball should always be released from there. During the ramp test, the ball may also have been released from different points. Although the ball was supposed to be placed on the ramp so that it would be released from the front, human error may also have compromised the precision of this measurement. In addition, human error may have caused unintentional and unnecessary force applied to the ball. To solve these design issues, a door should be made that holds the ball at a certain position for a fixed amount of time before the experimenter released the ball. During the catapult test, the ball may have been held back for an excessive amount of time. To resolve this experimental design issue, a fixed time to hold the ball back should be
Tip: The boomerangs fly best when pinched by two fingers in the middle and flicked with the creased edge forward.
methods (as explained above), such as quickly rolling the ball around the edges, to be sure of no
8. When finished recording your numbers from the two trail experiments take the average of each trial and compare the final results.
The group then becomes the standard of comparison. .:6. Design a (hypothetical) experiment that adheres to the Scientific Method. Be sure to include all the necessary requirements at each step and give examples at all of the steps. Start with an observation, whether it’s real or made up, state the null hypothesis, and design an experiment (including an experimental and control group, random sampling, sample size, and reproducibility) that will allow the student to reject or fail to reject the hypothesis, and state the conclusion (20 points.)
Use the following three-point rubric to evaluate students ' work during this lesson. * Three points: Students were highly engaged in class and group discussions; enthusiastically participated in the scavenger hunt; followed the rules of the scavenger hunt without needing
At least 10 minutes was taken up of each class so we could do the experiment. One of us went to the front and explain why we are doing it and what they were doing, while the other person passed out the test. To keep this anonymous experiment we only had them put the date and hour, then they had to flip over so they couldn't see the test, Once everyone had their test flipped over and they were ready we did on the count of three to get them started on the test. Giving them a minute to the test. Then later in class we graded all the test. Once we got all the test for the three days we got each class averages and compare how they class did within the three days. Also compared all of the rap, all the classical and all the no music. Likewise, the best way to organized our data was by a bar
Lab 1 – Introduction to Science Exercise 1: The Scientific Method Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organisms require oxygen to survive, it is a necessary component of water systems such as streams, lakes, and rivers in order to support aquatic life.
5. Analyze results – Assume that your experiment produces results identical to those seen in Table 4, what type of graph would be appropriate for displaying the data and why?
INTRODUCTION: The “Med-Squad” lab group was approached by a local manufacturer to create a toy bouncy ball that is both nontoxic and eco-friendly using only polyvinyl alcohol, polyvinyl acetate, and sodium borate chemicals. The interactions between polyvinyl alcohol and sodium borate, and polyvinyl acetate and sodium borate make an ideal
To qualify students are required to make a cardboard boat out of 2 by 4 foot of cardboard. It is suggested that the card board is split into two 1 by 2 foot pieces. The student is allowed to use duct tape that is 48mmm by 14m long. No other material should be added. The 4 best boats will be determined by the quality of the construction,
It was time for the next round. We came up to the table. The operators looked over the table to make sure it was ready. We started, and it was working! But then, we drove up to a model, and it fell over. This was huge. A big part of our points came from this. Since this didn’t work, that ruined this round.
METHOD: An air hockey table was set up and a video camera on a tripod was placed over the air hockey table. The camera was positioned so it was directly above the air hockey table facing downwards. The air hockey table was turned on and two near identical pucks were placed on the table, one at one end of the table and one in the centre. The puck at the end of the table was launched by
Rate= Final diameter-Initial diameter Time After finishing the Methylene blue experiment, we followed the same procedure to Potassium Permanganate. Each group presented the result to the white board, so that we can compare the results. We kept a record of the results and have a short conversation with our group mates in interpreting the results of the conducted experiment.
