Motors Lab

Today Lena Kathryn and I did the motors Lab. We learned that when electricity flows through things, it creates a magnetic field. the particles are negatively charged (cause they have more electrons- hence electricity) When the wires are coiled tightly, there is a stronger magnetic field.
A magnet has a push side and a pull side. These are called poles. Since the electricity is moving through the wire, the needle moves when it is pushed/pulled through the magnetic field.

Heat Shield Lab

On tuesday, Amalia, Alice and I tried to make a shield for our
"rocket." It was a piece of wood with a bolt hot glued to the end. We tried to keep the glue from melting for as long as we could.

This is a picture of our Heat Shield.
We had to make sure that the heat was reflected and the hot air wasn't directly getting through to the glue, so we used tinfoil to reflect the hot air the tinfoil got really hot, so we made sure that the tinfoil only touched the mesh wire stuff in two places. (convection- hot air, conduction- when things touch.) Our bolt stayed on the wooden stick for 3 minutes and ten seconds.
