Newton's rocket

Making The rocket

The first thing I did when making making the rocket was taping three straws to the sides. This helps keep the rocket stable before launch. Then we got a cork that fitted the bottle. The next thing I did was pour vinegar into the bottle until half way full. After we put some baking soda into a square of toilet paper and rolled it. Finally we went outside and launched the rockets. We did this by combining the rocket with the roll of toilet paper then we put the cork on.

Launching it

Because of miscommunication in my group, our rocket didn't launch. We put in the baking soda into the bottle but didn't put the cork on right so the pressure didn't build up enough to explode.

Newton's Cradle

Building the cradle

First glue the sticks together to make a structure for the marbles to hang off of. Next you cut string that are twice the length of a popsicle stick. After that you find the middle of the string and glue a marble onto it. Finally you tape the strings to each side of the structure and then you are down.

Testing it

Now that I assembled it I have to see if it actually transfers energy good. I pull back the marble and let go. The marble hits the other ones and one single marble comes out the other side and it repeats.

Density Gizmo

I practiced and learned about density using gizmo and this google doc.

I did an edpuzzle that helped me learn about specific heat.
