Today I researched different fin designs.  Although I already have my rocket completed, the fins are a bit big and bulky.  So I found another design i can use, and luckily I will only have to make some minor adjustments to my rocket.  Other than that my rocket will be perfectly fine and I will be launching on friday.

Today I found the scale I need to measure the mass of my water.  I already have my measurements so finding the water in KG should be fairly easy.  Also I have my launcher and my rockets built so other than putting together my project board I should be finished by the end of the week.

Today I had to figure out how much water I needed to use for my rocket.  I already had the amount in water, but I had to convert it to volume.  To do this I had to use the equation for volume, which was:
Volume=Mass       .  I also changed the amount of water used in my second rocket from .99 kg to .66 kg
