Our volcano explosion is made of baking soda and vinegar. Our group worked well we got everything done. Everything went well. What didn’t go well was our planing for our explosion we decided on a couple of things then changed.

After the project was finished, we felt satisfied. Laying out the problem was much more challenging than previously expected. The model was hands down the hardest part, however; making a triangular model, this being a city, and finding how to apply it was very frustrating.
Our story problem is…
Jim and Sally wanted to go to library to go get some books. From Sally’s house to Library A is 9 miles away. They went to the library and couldn’t find the book they were looking for. They decided to go to Library B. Library B is 10 miles away from Library A. They went inside and found the book! They then went back to home. What is the distance (or hypotenuse) to Sally’s house? Round to the nearest tenth.
A^2 + B^2 = C^2
9^2 + 10^2 = C^2
81 + 100 = C^2
181 = C^2
181=C
13.5 = C
Boat

This is my boat, it is named s.s.s.o.s. My group was Elijah, Weston, and I. Our time was 7.60 seconds, the fastest 1st trial in the class. We made our boat put of styrofoam, hotglue, tape, wood dowel, tin foil, and pipe cleaners. There where many things that made it slow, we should have made a tunnel down the middle do it would have gone faster. What made it fast was the sail because it catches the wind and propels the air backwards. One thing that made it bad was Allie splashed water on the sail so then we had to redo the sail.
