Impact Craters Experiment

Conclusion: The results of this lab were found through seemingly simple equations, basing all of your work off of data such as time and distance can become frustrating due to human inaccuracy, but the results show the height and initial velocity of the marble. The results are all reasonable compared with the beginning values that we collected during the lab, and even without calculations fit into the equation. The concept of projectile motion was the basis of this lab, focusing on using kinematic variables and equations to find the

The egg drop project is designed to use what we have learned in science and apply it to a more hands on project. The goal is to keep a raw egg from cracking or breaking after a 3 meter drop. There are quite a few constraints that go along with this project such as materials, time management, and deadlines. The only materials allowed to be used on this project are; 10 straws, 2 sheets of paper, 30 cm of tape, 5 Kleenexes, 1 sandwich sized plastic bag, 25 cotton balls, and 50 cm of string. The plastic bag must be used to contain the egg in case of breakage and the final product must fit into a 15 cm cube. All of the building work must be done in class.

Massive boulders rained from the sky; each breaking as it struck the ground. Debris scattered and

To determine whether the height at which a marble is dropped affect the size of the crater.

rate of fall of an object was determined by its weight held that matter was constructed out

Christopher and Kate noticed that after a rainstorm some of the rocks in their yard appear to shrink. They wondered how the mass of the rocks changed when dissolved in water. To

Snow globes are made of clear glass, a transparent sphere with a scenic view and a plastic toy inside the globe. The globe must be shaken to actuate the snow so the white particles can fall gradually to reach the base. When the marble (object used for this experiment) falls, it experiences two external forces which are; the gravitational force and the aerodynamic (fluid resistance) drag of the marble, which affects the rate of the marble. As the marble is falling, the speed is increased due to the gravitational force, which is pulling the marble downwards to the base of the beaker until it reaches the terminal velocity, where both external forces are equal. However, there are factors that can affect the marble’s terminal velocity, such as

5.Wearing gloves, remove each egg from the cup, rinse with water, dry off with paper towels, and measure each egg’s final mass

This is the final step of the experiment. The shell-less egg was now placed into a new cup, but very carefully, as the egg was more fragile than when it was soaked in vinegar. The egg in the new cup was then covered with water. The egg sat in the water for a 24 hour time period once again. During this 24 hour time period the eggs appearance and size were once again recorded. After the time period had completed, the egg was removed from the water and was very carefully patted dry. Since the egg was now swollen, extra care was needed when holding the egg. The swollen egg was placed on the scale on last time and its mass was recorded as M3.

Hypothesis: No the size of the crater and ejecta will change because it will have lighter and harder impacts on the surface.

Yes my hypothesis was that it would expand and it also stank from the vinger. Although I didn't think the structure would be rubbery or slimy after taking it out of the jar. Other than that my hypothesis was spot the on.

The origin of the second element on our periodic table still hasn’t fully been found, neither the many secrets that it holds. Helium is one of first know elements to every been discovered, and still is being examined and studied for any other hidden secrets that it might hold. While some people might believe that it’s a element that is hardly used, it would shock people to discover that as human beings, helium is a daily element that surrounds us not only just in the atmosphere, but is used for tons of different jobs and situations.

The content of this report is from the curiosity sparked by the experiment at Gravity Discovery Center. Dropping water balloon from the leaning tower, whereby the water balloons create craters as they crashed into the sand pit below. This experiment peaked the curious question “if a water balloon could have such an impact what was the damage done by the asteroids that ended the dinosaurs”.

4.14. The accuracy of the data is dependent on the correct controls being in place, Ensuring temperate stays the same throughout all solutions, making sure that the solutions are correct that the weight and size of the eggs are the measured correctly and that when the eggs are removed they are removed at the same time. Some of the eggs were not completely submerged in the solution this may cause some errors in the experiment and may have caused varying results. The eggs were of different sizes this also will cause the results to vary, Gathering eggs of exact size and weight would have ensured the results were correct. The eggs may not have been dried enough also causing results to vary; this can be fixed by ensuring that the eggs are thoroughly dried. The eggs were taken out at a time around about 24 hours, having an exact time to remove the eggs would have eliminated errors.
