Lab Conclusion When comparing the average speed results from part two of the lab and the definition of acceleration‚ you find similarities between the two. First‚ average speed is distance divided by time‚ and we use it to describe the motion of an object moving at changing speeds. We can see this from our lab results from the average speed of the marble traveling down the ramp‚ because it picks up speed. When the marble is released at the top of the ramp‚ the ball doesn’t have the same momentum

Conclusion 1: In this first lab we attempted to discover which of the materials given to us were hydrates by heating them and then dissolving them in water. Our results showed that all of our substances were hydrates besides the sucrose‚ sucrose if the only one which did not both bring condensation when heated and dissolve in water‚ which agreed with our hypothesis because we also thought that sucrose was going to be the only one that wasn’t a hydrate. The only error that we may have encountered

Daphnia Heart Rate Background: In the world today‚ there are many chemicals that people use to fix or help with issues within their own bodies. Some of these chemicals may include things like caffeine‚ nicotine‚ and alcohol. These supplements can have substantial effects on other things within the body like the brain‚ liver‚ and especially the heart. For example‚ many chemicals like caffeine‚ nicotine‚ aspirin‚ and sleep aid all have effects on the body which can cause your heart rate to increase

Anjali Patel Riley Egan‚ Nick Morrison 10/2/13 Block 2 LAB REPORT OUTLINE FOR DIFFUSION/OSMOSIS LAB Introduction: Diffusion is the net movement of small or uncharged molecules or substances from areas of higher concentration to areas of lower concentration. There is simple diffusion‚ as explained‚ and facilitated diffusion. Facilitated diffusion‚ on the other hand‚ involves larger or charged molecules or substances that need a protein tunnel through the membrane to help the substance enter and

Conclusion to Motion Lab Kerreon Wright 3rd Period Ms. Gislason The purpose of this Motion Lab was to find the acceleration of a steel marble going down a straight track six different times to figure out how an object’s mass affects acceleration. It doesn’t due to Newton’s second law of motion. There were six different accelerations for each trial and they are: 7.88 m/s squared‚ 6.78 m/s squared‚ 6.07 m/s squared‚ 5.57 m/s squared‚ 4.32 m/s squared‚ and 5.11 m/s squared. It’s possible

Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they

In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an
