Emani: Energy transfers

Location: 42.278372,-71.630173

This is a piece of metal being heated up by a gas burner. The burning gas is transferring heat energy to the metal.

Location: 42.367066,-71.070224

This is a Tesla coil that was being fired off at the Museum of Science. It transfers electromagnetic energy to the air surrounding it, which then causes the air to heat up to a state of plasma, so causing these electrical arcs.

Emani: Venation patterns

Mango Tree

Mangifera indica

Location: 42.278372,-71.630173

The leaves of a mango tree have a pinnate venation pattern

Chives

Allium schoenoprasum

Location: 42.278372,-71.630173

Chives have a parallel venation pattern

Harris: Bilaterally Symmetrical Organism

Syringa vulgaris
42.234445, -71.624035

Acheta domestica
42.275915, -71.750575

Chiu: Homeostasis of an organism

By sweating, this human, Homo sapiens sapiens, is maintaining his internal body temperature.

Crowley: Introduced species

Burning Bush (Euonymus alatus)

42.25006, -71.63126

This species is an introduced species that is invasive, as it was originally from Asia and introduced to North America. Burning bushes have been prohibited in Massachusetts since 2006 because it is considered a noxious weed; birds that eat the berries of the burning bush deposit the berries elsewhere, and this burning bush growth wipes out native growth. Therefore, the species is considered invasive and no longer allowed in MA.

Emani: Secondary Succession

Location: 42.278372,-71.630173

These are two areas in my yard that have been weeded out and have had plants slowly grow out of the bare soil

Crowley: Axillary bud

Mountain Laurel (Kalmia latifolia)

42.25006, -71.63126

Common Lilac Tree (Syringa vulgaris)

42.25006, -71.63126

Emani: Plant using either wind or water for seed dispersal

Kentucky bluegrass

Poa pratensis

Location: 42.278372,-71.630173

The bluegrass seeds can be seen in the foreground attached to the stem. They will separate from the plant with a strong gust of wind and be carried to other areas to be replanted.

Sugar Maple Tree

Acer saccharum

Location: 42.278372,-71.630173

The seeds of the sugar maple tree can be seen clinging to the branches in clusters. The will eventually break off, whereupon they will rotate like helicopter blades and fall gently to the ground or be picked up by the wind and be carried to other areas.
