Pendulum Lab online models. In case you are absent your assignment is to create a data table, pick a variable, change it and see how it affects the period of a pendulum.
The period of pendulum is the time it takes the pendulum to go back and forth....

We;re a bit behind the calendar y'all
Hi all,
We are a bit behind our own calendar. I've overbooked us for things to do... but the good news is we are catching up, getting organized. You have a large homework assignment for the break. Please finish that and check the printout at school for missing assignments.
Enjoy your break
Nina

Forks, Forks, Where did they go
Forks, forks, where did they go????
Our school has a problem. The forks dissapear. They just go away. We find them in the ceiling. We find them in the classrooms, but golly.... really... how silly is that. Now the reason we spend so much money buying metal forks is because plastic forks cause SO MUCH GARBAGE!!! The alternatives are biodegradable forks.
Our class wonders how do the biodegradable forks work?
