DATA:

-Daphnia: About 8 visible (1 large, the rest are very small)

The daphnia is more near the top of the water level than at the bottom where the pebbles are.

-Elodea: More of the tips are withering and ones is darkening into a dark brown color. It looks like the lighter one grew.

-3 roots (red strands) are growing from the top of the light colored Elodea. See Image 2

-Our four plants grew about 2 inches and they look healthy. The leaves on our plants also grew more! See Image 4

-The side of the bottle facing the window is very moist, which is evidence that condensation is occurring, but it has decreased from our last observation. See Image 4

-Water is clear with small pieces of plant residue floating.See Image 2

-Snails, one might be dead and the other snail looks healthy compared to our last observation and it lies an inch above the bottom where the pebbles are. See Image 7

-The soil has moved elevation, a result from the growth of the plant and its roots it is flatter than our last observation.                                           

-Two fallen seeds are covered in fungi which might be the moisture that caused it to grow. See Image 4

-There is a not much of a change in water level. See Image 6

-Wick fibers looks as if they are withering and coming apart.

Reflection: Other ways we could incorporate technology with this ecosystem project would be taking pictures every week and creating a flip book to see the process of how the ecosystem has changed. We could also incorporate technology by taking videos of the ecosystem, this would help with focusing on different angles of the ecosystem as well as zoom in. This would also allow for seeing any movement occurring in the ecosystem such as the daphnia. Also you could focus on different sections of the ecosystem such as zooming in. Students could also investigate and research about the things observed in their ecosystem, the causes for certain things that have occurred in their ecosystem, or things they may not understand or have no reasons of explanation for why they are occurring.  For example, students could research the reason: why the fungus has grown or how it has grown, what causes the seeds to germinate, why only four of the five seeds grew.
