Water Lab

Introduction:
 what has a stronger surface tension of cohesion bonds between water and alcohol

Step: 1 you want a pipette full of water
Step: 2 need a penny
Step: 3 you want to drop as much water droplets on the penny as much as possible
Step:4 you want to record the data of how many droplets of water you put on the water
Step:5 Try to put as much alcohol as you can on the penny without it falling off the penny
Step6: string stretch it as much as you can poor down water on it and see how much water can go into the cup by pouring the water on the string and see how much water the piece of string it carry alongside it




The graph below shows the amount of drops each penny was able to sustain and that it also shows that water has a better surface tension i have other data recored and it shows that water does have the better water tension than alcohol and the cohesion bonds in the water are greater 





Reflection: what i have learned is that water droplets on a penny does not cover as much as the alcohol droplets the penny is able to carry more alcohol droplets than water droplets 

Claim: i found out that alcohol will have more balance on the penny then the water will on the penny

corn lab

Questions does genetically modified corn grow better than non genetically modified corn when its infected with bugs ?


Procedure

I went to this site and grew some corn that was infested with bugs and grew some corn with few bugs and grew corn with no bugs

 Step 1: You want to pick the corn you first want to experiment with
 Step 2: You then decide if you want plain corn to grow or the corn to grow while being infested with a small amount of bugs or a large amount of bugs
 Step 3: Push the grow button and write and record what is happening is the corn growing fast with or without the infestation of bugs or is it the same ?
 Step4: Then record the data and put it into a graph data and see which corn grew the fastest and which did not and how was the corn affected by the bugs if affected at all ?





This is the data i have collected while during the corn lab each level of ECB infestation is High some of the data increases than slightly decreases but increases within time the corn was logically not affected by the bugs to have a positive effect on the corn anyways when it was infected with large amounts there was little corn and didn't weigh much but when put with little bugs or no bugs the corn will have a positive growth and be like regular corn

Evidence 
Research: In my research the good corn was the corn that had few bugs and the super corn had lots of bugs the bt123 had lots of bugs and the bt456 had few bugs and you can see that the corn grew just fine with small bugs but with a larger amount its growth decreased


Claim In the graph above, it shows that BT 456 is the one that weighed the most out good corn super corn and BT123

Reflection: My hypothesis for this lab was correct i knew that having few bugs on the corn while it grows would not effect the growth of the corn
