Introduction

Investigation into dissolving sugar BY JITESH PATEL 11C AIM: The aim of my investigation is how long sugar dissolves in cool and warm water (h20). PLAN: I'm going to use temperatures that vary from (30? -60?) for the water. I will use granulated sugar at room temperature. I'm going to dissolve the sugar in the water and take reading of the time it took to dissolve. To make this experiment a fair-test I will use a level spoonful of sugar. Then I'm going to take (50mls) of water each time. I will use a thermometer to measure the temperature. I will use temperatures of (20?/30?/40?/60?). After each experiment I will time it and record the data of my results on a chart. APPARATUS (EQUITMENT LIST): * Safety goggles (because of boiling water) ...read more.

29 SECONDS 24 SECONDS 25 SECONDS 31.1 SECONDS 60? 16 SECONDS 17 SECONDS 15 SECONDS 15 SECONDS VARIATION: In this experiment I could vary the types of sugar and the amount of sugar. I could also change the volume of water. I could also change the temperature. I could change different types of liquids. TABLE OF RESULTS: TIME TO DISSOLVE TO FIND OUT THE AVERAGE I ADD UP (1ST,2NDAND 3RD) AND DIVIDE BY 3 * Graph on the next page (LAYOUT OF THE EXPERIMENT) CONCLUSION: I have found out the higher the temperature the quicker it takes for the sugar to dissolve. I know from my I own knowledge that certain solids dissolve at certain temperatures. After drawing the graph, I found out I had to be more accurate with the experiment, but I'm still happy how my plots on the graph came out. ...read more.

Conclusion

Seventhly I wrote my variation this is just what other things I could change in the experiment. Eighthly I done my table of results in this I showed what I did in each experiment but on a graph and I drew out my layout of the experiment. Last of all I done my conclusion in this I wrote about the pattern of the graph and explaining the pattern using my science knowledge and evaluation this I have to talk about the plots on the graph, how could I improve the experiment and a summary of the whole investigation. I WAS JUST ABOUT HAPPY WITH MY GRAPH ON HOW IT LOOKED AND HOW THE POINTS CAME OUT. I COULD HAVE IMPROVED IT BY MAKING SURE IT WAS ACCURATE ENOUGH. BUT I TRULY TRIED MY BEST METHOD IN THIS GRAPH. I CAN IMPROVE MY METHOD BY PRACTISING AND LEARNING THROUGH INVESTIGATION. THE END THANK YOU FOR READING! ...read more.

    For the same amount of temperature we can use a thermometer. This is an easy factor to investigate and should give good results. 3. The temperature of the water. The temperature of the water is also an important factor because if the temperature of the water is higher then the water molecules will gain more Kinetic energy.
