Newton's Rockets

In this Project, we made a rocket using baking soda and vinegar. To do this, we used 3 straws, a empty water bottle, a cork, masking tape, vinegar, tissue, and baking soda. Our rocket was a failure both times we attempted because the straws weren't balanced. A principle of design that was used was movement. The reaction of the baking soda and vinegar made the bottle move. An element of art that was used was shape. We used straws to create a shape what made the bottle stand up. As a group, we watched a video and discussed how we would do this experiment. We got an empty water bottle and taped 3 straws to around the outside of the bottle to help stand it up. Then, we filled the bottle halfway with vinegar using a funnel. After, we found a cork that fit into the bottle. We then put baking soda into a square of thin tissue and made sure it was all contained. After we went outside, we put the baking soda inside of the bottle and put the cork in the bottle to secure everything inside the bottle. Then, we shook the bottle and placed it upside down so the bottle could stand up. The straws weren't level so the bottle fell over and the vinegar and baking soda mixture erupted from the bottle sideways and the bottle did not go up like it was supposed to.

Newton's Cradle

We created a cradle to show how energy and momentum transfers through objects. The materials used were popsicle sticks, twine, hot glue, tape, and marbles. We created a "box" using popsicle sticks and glued the twine to each of the marbles to make the cradle. Finally, we tested our cradle and it was successful! See below.
