this experiment throws a ball's with diffrent weight directly downwards to a box full of sand. As the weight of the ball increases, the size of the impact crater changes, assuming the ball is always dropped from the same height as measured from the top of the sand box to the bottom of the ball. The reason behind this experiment is to determine the relationship between the mass of the ball to size of the impact it made on the sand. The size of the impact is the dependent variable, the mass of the ball is the independent variable, and the control variable is the height at which the ball is dropped. Other controlled variables include the the surface of the sand.the experiment is limited to the depth of the sand box which is only 4 inches.
Materials used in the experiment:
* 5 Tennis ball
* Meter stick
* duck tape
* Balance
* Sand
* Box
* Knife
* Black marker
Method:
1. Take the tennis ball and weigh it by placing it on the scale
2. Grab the tennis ball and cut it it open by making a small circle on top
3. through the circle just made pour in some sand until the ball weighs .1 pounds confirm this by weighing the ball on the scale used in step one.
4. cover the whole by placing one layer of duck tape over it and ensuring that no sand comes outb of it.
5. repeat step 2, at step 3 add .2 pounds and proceed to step 4
6. repeat step 2, at step 3 add .3 pounds and proceed to step 4
7. repeat step 2, at step 3 add .4 pounds and proceed to step 4
8. repeat step 2, at step 3 add .5 pounds and proceed to step 4
9. at this point you should have 5 tennis balls each one with a diffrent weights of .1lbs, .2lbs, .3lbs, .4lbs,and .5lbs grab the black marker and lable each one respectivly from lowest weight being 1 to the heighst weight being 5...

8. Repeat from step 4 twice more so you end up with three results for
I started by weighing 4 bags on each side of the scale to see which side was lighter. Then from those results I thought to weigh the 4 bags that were on the lighter side by 2 and 2. After this you would find one side weighing less than another. Then you would take those results and weigh the 2 remaining bags and the lightest bag would be the bag that was taken from. However, the mathematician said it could be done in less than three steps. So throwing the answer I had just gotten to the side, I started new. This time I started with 3 bags on each side knowing that if two sides were equal than the bag with the missing gold would be one of the bags not weighed the first time. Then you would have to weigh the two remaining bags and whichever one was lighter than the other would be the bag with less gold. But, if the 3 bags from the beginning weighed different then you would weigh 2 bags of the 3 and if they are equal in weight than the 3rd bag is the one with less coins. If they weigh different the lighter bag would be the one with less coins.
If you choose to weight train 5 days per week, you will follow this cycle.
is the reason that the ball does not rebound off the block at the same
This forces the outside of the ball to push out and therefore bounce back up to 2. However, the ball will not bounce back to its original position. original height due to it losing energy as heat and sound energy when hitting the floor. Relevant Variables The independent variable in this investigation is the height of the ball is dropped from the sand.

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.
Step 1: EER = 354 – 207.3 + [1.45 X (9.361 X 59.02 + 726 X 1.651)].
The independent variables in this experiment are the height of the ramp, the length of the ramp, the surface of the ramp, the weight of the marble, the size of the marble, and the surface of the marble. The dependent variable is the distance the ball rolls. The controlled variables are the starting position of the ball, the angle of the ramp, and the surface of the floor. Units: The height of the ball from the ground, the height of the ramp, and the distance the ball rolls will be measured in centimeters (cm).
Investigating the Effect of Drop Height on the Depth of Sand Aim: To investigate the depth of the sand depending on the height at which the ball is dropped from. Variables: Independent variable chosen: The height at which the ball is dropped Dependent variable chosen: The depth of the sand after removing the fallen ball from it. Constant variables and how they will be controlled: Variable How we will keep it constant Amount of sand We leave the sand in the bucket and make sure that none spills over. Type of sand Use the same one for each trials Ball Use the same ball for each trial, with the same size, volume, material and brand.
