The weed essay is due today. Many are coming in, hope they all do! Today we did an experiment racing a marble down a ruler and bumping it into a cylinder. Students experimented with different ways to make the marble go faster or slower. Some timed it and found the actual speed and velocity of the object. We discussed Newton's laws, potential and kinetic energy, gravity and friction, all concepts we have been learning in class.
The final weed essay must be in on Monday as I will need to read them and have them turned in by Tuesday. I will have all corrected rough drafts ready to hand back tomorrow.
Ask Teacher: Homework, links and your comments
