Things to think about when using numbers, you can but the number, “4” unless it is in the beginning of a sentence spell it out “Four”
Research: Looking at Aristida stricta (Wiregrass) in different temperatures to measure the growth at a greenhouse
Introduction Information:
– start broad discussing climate change “climate change has resulted in a loss of biodiversity and address how that is a problem”
-discuss how astritida stricta is a native species
– use 3 of the following citations:
http://dx.doi.org/10.1098/rstb.2019.0104
https://doi.org/10.1046/j.1526-100X.2002.10107.x
https://www.jstor.org/stable/26613633-
-however it is not clear why .. there is little evidence showing..
Create a methods section for the following information using the research question:
Research: Looking at Aristida stricta (Wiregrass) in different temperatures to measure the growth at a greenhouse
-Spring weather, natural sunlight
-Psuedo replication happened as we were not able to replicate the temperature in multiple places due to it being a green house and one side of the green house receiving afternoon sun and the other side receiving morning sun.
-The wiregrass that survived dirt was rinsed off, put in a paper bag and then kept for a week after 40 C.
-present tense can be used if describing something still happening
-Seeds were not used: potted plants were purchased in a necessary and they were separated with individual clumps
-Statistical analyses: chi squared,
-Wiregrass was plotted on 2/8 and ended on 4/5
– Fertilizer was applied after one week and the fertilizer was a standard water soluble plant food (20:20:20, ENVY(R), National Liquid Fertilizer, Bedford Park, IL) that was applied at a concentration that was 25% of that recommended for indoor plants
-starting height of plants ranged from 9-15
Four treatments (when listing out treatments 2×2 factorial experiment with 2 water conditions (50 ml and 100ml ) that were watered twice a week.
Temp Water. Alive Dead
29 100 6 30
29 50b 7 29
24 100 13 23
24 50 5. 31
Temperature set at a minimum temperature was 17 C and maximum at 29 C,
Location: Greenhouse .. south side and north side of building …. Cool side (East) received a max of 24 C and the warm side max was 29 (West),
-minimum temperature on both sides was the same but the maximum was different
-plants were watered twice a week (Monday and Thursday) and watered with 50 mL
-plants were purchased at a native plant nursery, they were bought in half gallon plots, and separated into individual clumps
-give total sample size (144)
-plants were randomly assigned to positions in the green house (randomized in pairs) so that there was a high amount of water and lower amount of water was next to each other
-there is pseudo replication: not able to replicate the temperature in multiple places due to it being a green house and one side receiving afternoon sun and one side receiving morning sun
– a few things to remember for writing Methods: 1) the size of the pots (you can measure in greenhouse)
Results:
Temp Water. Alive Dead
29 100 6 30
29 50b 7 29
24 100 13 23
24 50 5. 31
-reporting biomass with bar graph and with standard deviations
-reporting survival
Write a Discussion with the following results: and suggestions with the following research question:
Research: Looking at Aristida stricta (Wiregrass) in different temperatures to measure the growth at a greenhouse
The hypothesis was: We hypothesize that Wiregrass growth will be affected by temperature, with optimum growth occurring at a specific temperature range.
-what did you find?
-biological explanations does the data agree or disagree with predictions or hypothesis? What do the trend or lack of thereof mean?
-relating results to what people has already
-how do the results compare to others?
-there was a trend towards higher survival
-consider alternative interpretations of the data
-wiregrass was not sensitive to the levels of water and temperature used in this expirements if we had more water or
-with huger survival, we might have been able to detect differences there could have been more dependable watering
-create an abstract!
-for discussion end by explaining why expirements like this are important
Other Notes:
A lot of evaporation in green house .. biological explanation “
Understand transpiration and plants are losing that water
Plants do worse at high temperatures and low water, cool
Create a hypothesis as well in introduction
