The following is my scientific summary for my Project:

"For this experiment, I used a cube as my regularly-shaped object and a rock as my irregularly-shaped object. I filled a small beaker to approximately 60 mL. First, I measured the one of the cube’s sides and found it to be 1.5 cm, which means that all sides of the cube are 1.5 cm. This means that when I drop the cube in the water, it should displace about 3 to 4 mL of water. Once I had dropped the cube into the water, the water level rose to 63 mL meaning my hypothesis was correct. For the rock, I used the displacement method; using this method, I saw the water rise to around 65 mL. This means that the rock’s volume is roughly 5 cm3.

Through this investigation, I found that the 1st method of determining volume, using formulas, only works on regular objects because they have equal sides; for example, cubes & marbles. This method of determining volume is more accurate than the 2nd because the displacement method is used for pretty much any kind of object, whether regular or irregular. By measuring something like a cube, you’re likely to get a more accurate answer than by dropping it into water.

I also found that the 2nd method of determining volume, using the displacement method, works for both regular and irregular objects. The second method of displacement for determining volumes works on both regular and irregular objects because both kinds of objects are taking up space in the container, causing the water to be displaced. However, the displacement method can only be used for solid objects, like the cube or the rock. The displacement method would not work on a cork because its density causes it to float on top of the water, rather than displacing it. A sugar cube’s volume can be found using the displacement method, but only if the cube is placed in a liquid that won’t cause it to dissolve; putting the sugar in water only dissolves it."

Thanks for checking my summary & plz let me know what you think! I really need an A on this assignment! Just so u know, I'm in 8th grade (if that helps in any way)
Thanks again,
Natasha

ALSO,

this project is overdue so i need this answered ASAP so i can turn it in TODAY!

Great work.. did almost the same practical

Hi Natasha! Your scientific summary looks great! It is clear and provides all the necessary information about your experiment, observations, data, and conclusions. You have also answered the questions provided in the instructions. Well done!

To answer your questions:

1. The first method for determining volume works only for a regular-shaped object because regular objects have equal sides, such as cubes or marbles. Therefore, the volume can be calculated using the formula specific to that shape.

2. The second method for determining volume, which is the displacement method, works for both regular and irregular objects. It can be used for any object that can be submerged in a liquid, as it measures the amount of liquid displaced by the object.

3. Both methods of measurement have their own advantages and limitations. The first method using formulas is more accurate for regular-shaped objects because they have known formulas to calculate their volumes precisely. On the other hand, the second method of measurement using the displacement method works for both regular and irregular objects. However, it may introduce some errors depending on factors like the accuracy of measuring the displaced liquid.

4. The displacement method of measurement would work for a cube of sugar, as long as it is placed in a liquid that does not cause it to dissolve. However, it would not work for a cork because it is less dense than water and would float on top, rather than displacing the liquid.

5. From this investigation, you have found that the first method of determining volume using formulas is more accurate for regular objects, while the displacement method works for both regular and irregular objects. You have also learned that the displacement method may not work for objects that float or dissolve in liquids.

Overall, your summary is well-written and addresses all the necessary points. Great job on your project! I hope you get an A on your assignment. If you have any further questions, feel free to ask. Good luck!

Great job on your scientific summary, Natasha! It's clear that you have a good understanding of the concepts and methods used in your project. Now, let's address the questions that you need to answer in more detail:

1. Why does the first method for determining volume work only for a regular-shaped object?
The first method you mentioned is using formulas to calculate the volume of an object. This method works only for regular-shaped objects because they have equal sides and symmetrical dimensions. For example, cubes, spheres, and cylinders are considered regular-shaped objects. By knowing the measurements of just one side or dimension, you can easily calculate the volume using a specific formula. However, irregular-shaped objects do not have symmetrical dimensions, so you cannot use a simple formula to calculate their volume.

2. Will the second method for determining volume work for any object or just an odd-shaped one? Why?
The second method you mentioned is the displacement method, which involves measuring the increase in the volume of a liquid when an object is placed within it. This method works for both regular and irregular-shaped objects. It is not limited to odd-shaped objects only. The reason this method works for any object is that all objects, regardless of their shape, occupy a certain amount of space or volume. When an object is placed in a liquid, it displaces some of the liquid, and by measuring that displacement, you can determine the volume of the object.

3. Is one method of measurement more accurate than the other? Why or why not?
In general, the displacement method is considered more accurate than using formulas to calculate volume. This is because the displacement method directly measures the volume of the object by measuring the volume of liquid displaced. It does not rely on assumptions or idealized shapes. On the other hand, using formulas may introduce errors if the object's shape is not regular or if the measurements of the object are imprecise. However, it's important to note that accuracy also depends on the precision and care taken in the measurements.

4. Would the displacement method of measurement work for a cube of sugar? What about a cork? Why?
The displacement method would work for a cube of sugar because sugar cubes are solid and have a defined shape. When placed in a liquid, such as water, the sugar cube would displace an amount of liquid corresponding to its volume. However, it's important to use a liquid that won't cause the sugar cube to dissolve.

The displacement method would not work for a cork because cork is less dense than water and tends to float on top of it. It does not displace a significant amount of liquid, which makes it challenging to measure its volume accurately using the displacement method.

5. What did you find out from this investigation? Be thoughtful in your answer.
In your investigation, you discovered that the first method of using formulas to calculate volume works only for regular-shaped objects. This method is more accurate for regular-shaped objects because it relies on their symmetrical dimensions.

You also found that the second method, the displacement method, works for both regular and irregular-shaped objects. It measures the volume of an object by measuring the volume of liquid it displaces. However, it is not suitable for objects that float or dissolve in the liquid.

Overall, you've done an excellent job with your project, and your summary provides clear explanations and answers to the questions. Keep up the good work, and I hope you achieve that A on your assignment!
