1. Molecular Model of Methane
Research was done to find out what the atoms were and how they bonded with one another. This led to the discovery of the symbol for methane as CH^4. It is a covalent bond due to the fact that carbon has four valence electrons and hydrogen has one. This means that the four empty spaces in carbon want hydrogen to hook up and attach there.

2. Comic Strip Aurora Borealis
The
format of this entertaining assignment was done using Pixton, a Google
app for making comic strips. The Aurora Borealis starts with the sun's
emission giving off a bunch of protons and electrons. Its called the
Coronal Mass Ejection (CME). When it passes through the magnetosphere,
the protons and electrons collide and react with different particles
such oxygen and nitrogen.

3. iMovie with the three M's
There
are five mnemonic devices to remember the three M's of meteor, -ite,
and -iod. One of the five mnemonic devices is "meteor, the bright
light." This tells that the meteor is referring to the light that is
being produced. A second device is "meteoroid, just the dust." This
explains that meteoroids is the stuff that burns up. The third device
is "meteorite, it made it through." These pieces actually make it to earth. Next, "meteorite, rocks on
earth are -ites." Finally, "in the sky they soar...meteoroids and
meteors." Using these devices, the three M's can't be forgotten.

4. Blog Post: Mars Pathfinder and Sojourner
The
Pathfinder landed on July 4th, 1997 and provided many pieces of
information for scientists to analyze. There were new ways to land the
Pathfinder and Sojourner that were attempted. Risks were taken and
discoveries were made.
