Our group's manipulated variable was the density of the surface. Our group added two cups of sugar on top of flour. By adding sugar, marbles made less rays and smaller craters. I learned that sugar is denser than flour.

Our manipulated variable was the density of the surface by adding sugar. By adding the sugar, the marbles barely made any rays. The craters were really small, and the marbles were often above the surface. I learned that sugar is a lot more dense than flour and cocoa.

What I learned from the moon crater experiment is that if you change the mass of the marble then it will make a bigger hole but sometimes stay above the hole. And sometimes the marble will go in deeper and make a small hole. Some effects of the manipulated variable is that the bigger marble would sometimes make bigger and longer rays.

I learned that the diameter of any crater changes when the mass of the marble changes. When we increase the mass of the marble there were massive differences from the normal marble, such as the ray lengths were much longer when we changed the mass.

If we changed our manipulated variable than the marbles would produce wider craters, and bigger rays because the sand is so thick that it barely makes any rays.

Before we did this experiment, I didn't know what the rays were, and how they were created. From this experiment, I learned what they are, and how they are created. The effects from changing the variable was that when we dropped the marble, we didn't get many rays. Maybe 1 or 2. Also all of our marbles were above the surface.

During this lab I have learned many things. And this is the main things I learned. the density of moon is a big variable to the crater size, If we put a dense surface the crater will be smaller but the rays would be longer, and if the surface is less dense the crater would be bigger but the rays would be shorter.

When we changed the mass and the size of the marble, I learned that it makes a longer rays and crater diameter. Sometimes when we threw the marble, it would make a deeper hole though a smaller diameter.

Something that I learned from the moon crater experiment was if you drop something from the same height more than once, then it will most probably make similar sized crater and the rays will probably be similar lengths. Our manipulated variable was the shape of our marble. The effects of changing our manipulated variable was that crater and ray lengths became a little bit longer.

I learned how the craters are created on the moon. I didn't know what craters were before this experiment. The effect of changing the manipulated variable was that the surface of the moon got stronger. Therefore, it made the marble hard to get through the flour and sand. It also made the rays harder to spread.

My group's manipulated variable was the shape of the marble. Our group changed the marble to stone. When we change the stone, we find out that the stone's length is longer than the marble's length. The data had clearly show that the results were really different.

Our group added two cups of sugar so the surface became harder. The craters were smaller compared to when we didn't add sugar to the surface. I learned that when we increased the height from which we dropped the marbles, the crater got bigger.

Our manipulated variable was the marvel form ( we changed it to a rock) and what we saw and or learn was that when we throw the rock the crater will become wither.

From the moon experiment, I learned stuff like - cocoa smells really appetizing, marbles can make really long rays when dropped, craters created by marbles can be of big diameter, etc.
Our manipulated variable was the marble. Because we increased the size, the length of rays increased immensely as well as the crater size. Also, it was consistently BELOW the surface instead of a mix between below, above, and even.

I learned that when we changed the variable to a bigger marble the ray get bigger. Also the marble diameter gets bigger.

Our manipulated variable was the marble's mass ( bigger marble). I learned that with the bigger marbles it produced bigger craters, longer ray lengths and the crater depth was almost always below.

Our manipulated variable for the moon crater experiment was changing the marbles size and mass. What we noticed in our data was that the ray lengths were much longer, because the larger the mass the larger the impact it makes. Also the crater diameter increased from the smaller marble. We also noticed that sometimes the data was less consist with the larger marble than the smaller marbles.

What I learned during the experiment was that when we dropped the marbles on the flour, it had a a very low surface since it was very soft. About the sugar, it was acting like a gate for the marble when it dropped. So it had a high surface.

I learnt that the surface of the moon affects how the craters look. I learnt that because we changed the manipulated variable from flour to sugar and the craters were smaller because the sugar was harder.

Our manipulated variable was changing the form of the asteroid. I saw that the object always had different information because all the sides were not even and they all dropped at different angles which made different results.

One thing I learnt in this experiment was that a crater's outline in the moon after they've landed varies on its mass and size before and on the point of impact. We did this in our experiment by using a marble of a small and large mass respectively, and after dropping them at various heights we saw that the marble with the bigger mass had a much deeper depth in the makeshift moon surface and it's ray lengths were longer than the marble with the smaller mass.

I learned how craters were made, and about rays. For our manipulated variable, we changed the marble to a heavier rock. The manipulated variable's effects were not that different from the original. The rock did make a few deeper craters, but not necessarily longer rays. It also effected the info because the crater diameter was different, it increased and decreased.

I learned that when you changed the size of the object that you drop, it will increase (if the object is bigger) or decrease (when the object is smaller) the diameter/the ray's length. I think that this is helpful information because, it is basically impossible, that the size of the object that hits the moon, will be the exact same. I know that this is impossible because it is very hard to create an object with the exact shape/mass. We are able to do it because of simple machines that we can access.

Our manipulated variable was double the mass of the marble. I learned that, when a object is more dense or has more mass it creates a bigger impact; it also creates a bigger ray length.
