Newton's Rocket 

We built this rocket by researching how to make a baking soda rocket. The first step we did was empty a water bottle and tape 3 straws to the sides so it could balance on its own. We made a small packet of baking soda and 2-ply toilet paper and filled the empty water bottle halfway with vinegar. Then we got a cork and put tape around it so that it could fit tightly onto the mouth of the water bottle. After we were done building we went outside and attempted the experiment, ultimately, it failed because our baking soda packet was too big to fit into the bottle. 

Balance, Movement,  and space - As I already stated the straws were used to balance the water bottle so that we did not have to get too close. We had to tape the straws to the bottle with some space where the bottle mouth was so that the baking soda could shoot out and hit the ground, causing the bottle's movement to fly in the air. 

Newton's 3rd Law: Every action has an equal and opposite reaction. 

•  This applies to the rocket because the causing action is putting the baking soda into the vinegar while the resulting action is the rocket exploding. 

Newton's Cradle 

We built this cradle by watching a video on all the steps, then we gathered all our materials and started. First, we got 8 popsicle sticks and glued them together to make 2 squares. Second, we took 7 evenly cut strings and hot glued the middle of each string to 7 marbles. Third, we hot glued 4 more popsicle sticks to one of the previously made squares so that it sat on top of the other in a cube. Fourth, we took the strings with the marbles and taped them in the cube so that the marbles hung down in the middle, with the strings taped around 2 opposite ends on the top of the cube. Fifth, we hot glued 2 more popsicle sticks to the top of the cube, covering the strings and tape. Finally, we glued more popsicle sticks to the bottom of the cube to make the bottom. 

Movement and color - Movement was used by the marbles. When you let go of the marble and it hits the other ones it causes them to move. Color was used in the marble design, with the green inside of the marble along with the clear parts. 

Newton's 3rd Law: Every action had an equal and opposite reaction. 

•  This applies to the cradle because the causing action is picking up one of the marbles on the end and letting go, while the resulting action is the other marbles moving because of the marble that was let go. 

Newton's 2nd Law: A net force acting on an object causes the object to accelerate in the direction of the net force. 

•  This applies to the cradle because of the movement of the marbles hitting against each other. The net force is the first marble when dropped, and the objects it's acting on are the other marbles, which then causes the other marble on the other side to accelerate in the direction the first marble set.
