1 By Charlotte Bagnall Use a line transect and appropriate quadrats to collect quantitative and qualitative data to show how changing abiotic factors affect the distribution of organisms along the transect.

2 I predict that the further away that we are from the shaded area, the more plant species we will find because there will be more moisture in the ground which will give the plants more nutrients. Furthermore, there will be more sunlight to help the plant species to grow.

3 A quadrat 10m tape measure Area where there are a verity of different plant species Soil thermometer Light meter

4 Step one – Find an area of area outside where there are lots of plant species Step two – Line a 10m tape measure laid along the grass making a marking in the ground by digging a little chunks of soil out from the ground. Make sure it is large enough to see. Step three - Place the quadrat on the ground at each meter that is marked on the tape measure. Step four – Now that it is placed, count the number of all the different plant species that are there and plot down in your results table

5 Find the grass area Place down the tape measure Count the number of plant species Name the plants correctly

6 Measure the sunlight Measure the ground temperature Collect the soil

7 Risk assessment HazardRisk Safety Precaution How to prevent it Rating The quadrat Could get hit over the head by it Lay the quadrat on the ground when not in use. Got to matron for an ice pack 1/10 Allergies You could have allergies to the plant species Make sure to take you’re your mediation outside with you Get to matron for medical help 7/10 Wooden Logs Could trip us on large logs and break something Make you’re your just walking not running Go to matron for ice pack or if leg is cut, a plaster 6/10

15 In conclusion, my results show, that the plant species corresponded with the soil temperature which meant when the soil was cooler, the more plant species there were. I found this rather strange as it goes against phophotosynthesis. This is when the plants need more light. Therefore I feel that I would need to of retest this again.

16 We were able to gather our results in this investigation because there were a good verity of different plant species. What didn’t work so well was as it was our first time trying to identify the plant types, there is a risk that we may have got the plant identification wrong. If we were to do this experiment again, I would make try to find the plant species from a different area of the field to see if my results would be different. Also I would repeat this two or three more times. We didn’t have to make any amendments/ modifications throughout the experiment.
