1st prd. Assignment - 9/10
At this point in our class, we have been using time as our independent (x-axis) variable - everything has been dependent on time (ex: the distance traveled depended on the time; as time went on, our distance increased). The graph below shows the results of an experiment conducted to see the relationship of 'dissolve time' and 'temperature' of salt in water. This graph now shows time on the y-axis, which indicates that it is our dependent variable. Is this possible? Explain.

The graph called Experiment: dissolving salt in water is possible/ correct because in this case the temperature is the independent variable. The reason is because the independent variable is what I change and in this case that is the temperature. The cause of the independent variable is the dependent variable. The temperature is what effects the time is dissolves or in other words how long the salt took to dissolve. So, the Temperature is on the x-axis and the Dissolving Time is on the y-axis. Most of the time, the time is on the x-axis, but here in the correct graph it is not. Also, it is not time in hours it is how long it took to take the salt to dissolve in the water. Grace Barden
ReplyDeleteYes, I think that it is possible to use the time as the dependent variable and put it on the y-axis because it is saying that as the temperature rises the time it takes for the salt water to dissolve becomes shortened. It still makes sense to use time on the y-axis.

The reason why it decreasing is because the salt is starting to dissolve in the water. Because the longer it stays it the water the salt dissolve. That why the salt is taking a while to dissolve in the water . The temperature matters if the salt dissolves faster or slower. If the temperature warmer it might dissolve faster. But if it is colder it might dissolve slower.

This graph may possibly be correct even if time is not put on the x-axis; the reason is because in this experiment the time is not the independent variable. In the experiment we are trying to find how fast salt dissolves according to the temperature. Time is depending on the temperature, if the temperature changes, so does the time. If the time changes it does not affect the temperature. Therefore this graph is possibly correct.
ReplyDeleteYes this can be done correctly meaning, the temperature is something I can change. The dependent is something always will be the same! So in this case it can be done. The cause of the independent variable is the dependent variable. In this case the temperature affects the time. On the y axis is the time it takes the salt to dissolve. On the x axis is the temperature the salt dissolves in. So yes this can be don’t simply and correctly.
ReplyDeleteThe experiment: dissolving salt in water actually is possible because for this experiment and all experiments have the independent variable on the x-axis. The independent variable is the part of the graph/experiment that I can change and I this case it would be the temperature. the temperature affects the time that it takes to dissolve because the cause of the independent variable is the dependent variable.so yes this graph is correct and the time goes on the x-axis and the temerature on the y-axis.
ReplyDeleteI think this is possible because we have been talking about time always being are indepentent variable, but in this case the time is depending on the temperture. To support my answer in science we did this experiment that had time on the y-axis like this graph. That is why I think it is possible to hav the time on the y-axis
ReplyDeleteThis is possible because the temperature is the independent varibul and in the experiment the salt depends on how hot the water is. Time doesn’t affect how fast the salt dissolves temperature does and time is normally the independent variable but because you put what the temperature does to the salt the whole scale changes. Dakota p smith
ReplyDeleteYes. This is possible because in this experiment the temperature is independent and the dissolve time is depending on the temperature. This is true because in this experiment all of the temperatures are set to different temperatures and the salt may dissolve better at different temperatures. For example if you put salt in cold water it won’t dissolve as good as if you put it in boiling water. So that’s what I think about the experiment.
ReplyDeleteIt is possible that time could go on the y-axis. Almost always time goes on the x-axis, but for this experiment the dissolve time has to depend on the heat of the water. It would not make sense to put time on the x-axis because temperature doesn’t depend on time.
ReplyDeleteYes, I think that in this case time can be the dependent variable. The length of time that the salt will dissolve in the water will depend on temperature of the water. The hotter the water climbs the faster the salt will dissolve. On the other hand if the water stays at room temperature then the salt will take a longer time to dissolve.
ReplyDeleteYes, It is possible that time can be the dependent variable on the y axis. This is possible because in class, we have been discussing how time always has to our independent variable but in this case, time has to be the dependent variable. The reason is that in this experiment, time depends on temperature because if the water that is used to dissolve the salt is a certain temperature, it can change the results of the experiment. That is why time can be an independent variable for the type of experiment that we were given.
ReplyDeleteYes, I think it is possible that time could be the dependent variable and on the y-axis. In this experiment, temperature is the independent variable and time is the dependent variable. On this graph we are changing the temperature and not the time, so it’s okay for the time to be on the y-axis as the dependent variable because the dissolve time is depending on the temperature of the water. The dissolving time is decreasing because we are changing the temperature, that’s why we put temperature as the independent variable and time as the dependent. Sydney McNabb
ReplyDeleteIts is possible that time be the dependent variable because its controlled. As for temperature its independent cause its not being controlled cause its just going on and on.
ReplyDeleteYes, I think its very possible that the dissolving time (dependent variable) can be the on the y-axis while the temperature (independent variable) is on the x-axis, because the time depends on the water temperature for the salt to dissolve in the water. This is because when the temperature rises the time for the substance to dissolve grows.
ReplyDeleteIt is possible because from the graph temperature (x axis) depends on the time (y axis). Over time the temperature decrease.
ReplyDeleteYes, it is possible for time to be the dependent variable on the y-axis and have temperature on the x-axis. This is possible because we are controlling the time in the experiment. Which allows us to place the time on the y-axis and temperature on the x-axis.
ReplyDeleteYes it is possible to put time on the y-axis. You usually put time on the x-axis though. The only reason you’re not putting time on the x-axis for this graph is because the time of when the capsule dissolves depends on the temperature of the water.

Yes, this is possible to put time on y-axis. Most of the time u put the time on the x-axis but in this case u dont. The reason you dont put the time on the x-axis is becuase when you change the temperture it changes the time. In this experiment you can controled the time. Thats why it is possible to put the time on the y-axis sometimes. Nathan DeGrado
ReplyDeleteYes,its possible to put time on the y axis because the dissolve time depends on the water temperture.so that makes it dependent.-faisal
