Reason for performing Part A this experiment is to measure and record the distance from the target and diameter of the shot. Reason for doing this Part B experiment is to measure the mass without fluids then measure the mass with fluids. Also, the results of the experiments are different throughout the experiment. The lab experiment was consisted of a target, a ruler, and a magnum balls. First, we performed the experiment alone then work in groups. The procedure is to drop the magnum balls three times and measure the distant with a ruler. After measuring the distant, we get into groups and performed the previous procedure.

Result and Discussion Part A experiment involves with using a target, a ruler, and a magnum ball. Reason to perform this method is to measure the distant from the bull’s eye and the location of the magnum ball lands. After measuring the distant, the individual must get a partner and perform the experiment again. After performing the experiment alone three times, the results for the distant from bull’s eye are: 2cm, 4cm, and 6cm. The lowest average distance enclosing the shots is 2 cm. The result wasn’t the expectation of the person performing the experiment. There’re some tedious and yet encounter while performing the experiment. For instance, using the digital beam balance the person must remember to press zero before placing the cylinder on the scale. Then, measuring the plastic tube was the difficult tactic because the millimeter on the plastic tube are smaller than the graduated cylinder. This method possess concentration and a sturdy hand to get on the 8mL mark.
to get an idea of how I would do my real experiment and what apparatus
The procedure of the lab on day one was to get a ring stand and clamp, then put the substance in the test tube. Then put the test tube in the clamp and then get a Bunsen burner. After that put the Bunsen burner underneath the test tube to heat it. The procedure of the lab for day two was almost exactly the same, except the substances that were used were different. The
The results of this experiment are shown in the compiled student data in Table 1 below.
Using the scopula, take a small amount of the substance and add it to the spot plate. Add deionized water to the section with the substance. Stir to see if the substance dissolves or not. Record your observations.
3. Add on of the following volumes of distilled water to the test tube, as assigned by your teacher: 10.0mL, 15.0mL, 20.0mL, 25.0mL, 30.0mL. (If you use a graduated cylinder, remember to read the volume from the bottom of the water meniscus. You can make more a more accurate volume measurement using either a pipette or a burette.)
Planning Firstly here is a list of equipment I used. Boiling tubes Weighing scales Knife Paper towels 100% solution 0% solution (distilled water) measuring beakers potato chips Cork borer. We planned to start our experiment by doing some preliminary work. We planned to set up our experiment in the following way.
I am going to carry out an experiment to measure the change in mass of
Start with the hot water and first measure the temperature. Record it. 8. Then pour 40 ml into the beaker. You can measure how much water was used by looking at the meniscus.
Measuring cylinder to measure small amounts of fluids. Pipette to gather small amounts of fluids. Test tube holder to hold test tubes. 2. Molar Salt solutions to submerge potato chips in.
To investigate the affect the material of a ball has on the bounce height of that ball where the drop height (gravitational potential energy), temperature, location, ball, and air pressure of the ball are kept constant.
Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. The first independent variable that will be tested.
There is also the potential of human error within this experiment for example finding the meniscus is important to get an accurate amount using the graduated pipettes and burettes. There is a possibility that at one point in the experiment a chemical was measured inaccurately affecting the results. To resolve this, the experiment should have been repeated three times.
Possible sources of error in this experiment include the inaccuracy of measurements, as correct measurements are vital for the experiment.
2. In the large beaker, put water and boil it completely. After that, remove the beaker from heat. 3. Sample tubes (A-D) should be labeled and capped tightly.
