Biography

This is an exciting opportunity and I would love to be considered.

I am a National Board Certified science teacher. I hold a BS in Environmental Science and a MEd in Curriculum and Instruction from the University of Vermont. I have taught science full time since 2003. In that time I have successfully instructed biology, environmental science, physics, chemistry, and earth science at all levels from basic to Advanced Placement. Additionally, I have tutored many students in science, math, study skills, and standardized test preparation (SAT, ACT, and MCAT).
I have first-hand experience with computers, web development, and STEM education.

SCIENTIFIC INQUIRY Herbivory (plant eating) has evolved
repeatedly in insects, typically from meat-eating or detritus-
feeding ancestors (detritus is dead organic matter). Moths and butterflies, for example, eat plants, whereas their sister group"
(the insect group to which they are most closely related), the
caddisflies, feed on animals, fungi, or detritus. As illustrated in the following phylogenetic tree, the combined moth /butterfly
and caddisfly group shares a common ancestor with flies and
fleas. Like caddisflies, flies and fleas are thought to have evolved
from ancestors that did not eat plants. There are $140,000$ species of moths and butterflies and $7,000$
species of caddisflies. State a hypothesis about the impact of
herbivory on adaptive radiations in insects. How could this
hypothesis be tested?

Physics

CE An object of mass $m$ is initially at rest. After a force of magnitude $F$ acts on it for a time $T$ , the object has a speed $v .$ Suppose the
mass of the object is doubled, and the magnitude of the force acting on it is quadrupled. In terms of $T,$ how much time does it take
for the object to accelerate from rest to a speed $v$ now?

On a planet far, far away, and astronaut picks up a rock. The rock
has a mass of $5.00 \mathrm{kg},$ and on this particular planet its weight is
40.0 $\mathrm{N} .$ If the astronaut exerts an upward force of 46.2 $\mathrm{N}$ on the rock, what is its acceleration?

In a grocery store, you push a 15.4 -kg shopping cart horizontally
with a force of 13.4 $\mathrm{N} .$ If the cart starts at rest, how far does it move
in 2.50 $\mathrm{s}$ ?

You are pulling your little sister on her sled across an icy (friction-
less surface. When you exert a constant horizontal force of 120 $\mathrm{N}$ ,
the sled has acceleration of 2.5 $\mathrm{m} / \mathrm{s}^{2} .$ If the sled has a mass of 7.4 $\mathrm{kg}$ ,
what is the mass of your little sister?

A 0.53 -kg billiard ball initially at rest is given a speed of 12 $\mathrm{m} / \mathrm{s}$
during a time interval of 4.0 $\mathrm{ms}$ . What average force acted on the
ball during this time?
