This field extends infinitely <span class="highlight">in</span> all directions but gets weaker as you get farther from the source of the field. <span class="highlight">Magnetic</span> lines of force show the strength and direction of this field. The students will explore the lines of

What is the path that they take? • When scientists are <span class="highlight">using</span> remote sensing to explore areas <span class="highlight">in</span> space, they need to "fine tune" the use of echolocation to include speed, distance and elapsed time. The students will use the slinky to determine how the elapsed time <span class="highlight">in</span> which a <span class="highlight">wave</span> travels gives some information about the distance the <span class="highlight">wave</span> has

compressions meet rarefactions, then destructive interference will occur resulting in a reduction in the loudness of the sound at that location. One means of reducing the severity of destructive interference is by the design of walls, ceilings, and baffles that serve to absorb s...

So, not only is this the incredible shrinking planet, but that shrinkage was greater than we anticipated, and that shrinkage is going to be a very important constraint on when, and by how much the planet cooled, and how much of that internal heat, in the core, could have been converted into the kind of energy needed to sustain a magnetic field – and that, in
