Sound
How loud a sound is, is called the
volume
When we make circuits, we need to make sure that ________________ is touching ________________ at all times.
metal
In science when things move we call that
work
We usually associate the word "thermal" with
Light waves generally travel in a
straight line
Volume is measured in
decibels
Copper is used as wires because copper is a good
conductor
When the roller coaster car is at the top of the hill, we say that the car has a lot of ______________ energy
potential
My pots and pans are made out of copper and steel because both of those are good
conductors
When light waves bounce back we call that
The words we use to describe pitch are
high and low
Wires are covered in plastic because plastic is a good
insulator
When the roller coaster is speeding down the hill, we say that's _________________ energy
kinetic
There is a plastic or rubber handle on my pots and pats because both of them are good
Insulators
When light waves bend we call that
The piccolo is very short compared to the flute, so it has a more ________________ pitched sound.
high
When we want to turn our circuit on an off, we can use a
switch

Length of the string
In our thermal experiment outside we found that in the sun, some substances...
were warmer than others
When I put a pole in the pool to clean it, the pole looks like it's bending. This is due to
We used different sized _________________________ to help us determine pitches in class.
tuning forks
In a ___________ circuit if one light goes out, they all do, but in a _________________ circuit only the light that's not working will turn off.
series, parallel
We only changed one things each time when we worked on the flippers. Why did we only change one thing each time.
to know which ones make a difference.
In our thermal energy experiment outside, when we moved to the shade we found in all substances...
the temperatures went down
Light reflecst best off of things that are
shiny and smooth
