This space station has plants growing inside it, and astronauts who eat the fruits and vegetables from those plants. Because it is in space, the station is sealed so no material can get in or out.

The space station is in Earth’s shadow, so no light is getting into it. The sensors in the space station show that carbon dioxide in the air is increasing.

What is happening to the energy storage molecules in the plants and humans in the space station? Explain your answer as completely as possible.

Growing plants in space is tough -- low gravity means water distribution is difficult to manage, the roots are often starved of oxygen, and stagnant air reduces evaporation and increases the leaf temperature

Hal wonders about the properties of electromagnetic waves that make up the visible light spectrum. He conducts an experiment to see how sunlight behaves while moving through a prism. He is able to separate visible light into colors of the rainbow. He notices that each color has a unique wavelength and frequency.


Hal wonders which colors have the highest and lowest frequencies. Rearrange the colors into the correct order on the lines in the second column. Place the color with the highest frequency wave at the top, and the color with the lowest frequency wave at the bottom.

When looking at your pictures in order, describe the changes to the area. What changes happened first? Why do you think that is?

answer: There are changes in the climate which result in the environment changing. I think that in the picture before the eruption you can tell when this is because it shows the most "natural" of them all, with snow in the beginning and then it melts into picture number 2 which is the one right after the eruption. it shows climate changing resulting in the mountain snow to melt faster and develop into something similar but different.
5. Colonizing plants help prepare the soil for the growth of other species of plants Look at time lapse photographs of the Scorch, standing dead forest from 17 and 30 years after the blast on the site http://www.mshslc.org/return-to-life/changing-landscape/. Are these different plants than you saw in the photographs from Question 2?
answer: ???
