OPEN PLANT LAB EXPERIMENT
Hello classes please note the following about the lab.
There were no seeds left to compare the initial mass of the seeds to show a linear correlation to the end bio mass. Please still include this portion in your lab, however if you were unable to obtain the seeds mass no problem just graph the final biomass of your plants for number 11 in the lab. No marks will be deducted for those who do not habe the seed masses included.
if there are any questions please use the blog site to ask.
As for the presenttaions for GENETIC DISORDERS. YES...you may do it it in partners. I strongly encourage that!

Hi Mr. Smith
For the plant lab, for the graphs, do we leave it all in pencil after colouring (ex the labelling of our axis and title) or can we outline them in black marker?
thanks shannon
have a great weekend!!
P.S. i have already done the graph for the biomass with the seeds because when i came in there was still seeds yesterday...can i still include that graph in my lab?
Do we have to do these graphs by hand?
Yes please do the graphs by hand!
Yes if you have all ready done the graphs please include them. As for outlining them in black marker is fine if you wish.
hi mr. smith,
so for the biomass graph do we just graph our final biomass. so there will be only one point on the line, and it's still a linear correlation. thanks
mariam^_^
yes that is exactly perfect mariam!
what if we have already done all of the graphs by computer and the whole lab is finished, do we have to re-do them by hand?? will we loose marks if they are not done by hand? can we have on biomass grid with all of the seperate graphs indicated by different colours? Thank You!
Heyy mr smith,
after reading the posted comments i'm confused, are we supposed to just eliminate number 11 all together or just do part of it? People have posted comments about just graphing the final biomass...are we supposed to do that?
If you were able to mass the seeds then show all the data pertaining to question 11.
However if there were no seeds to weigh , yes I still want the data of the final biomass in a graph. No marks will be deducted for those who were unable to mesaure the seeds as the were taken or lost by another group of students.
so do we have to do the graphs by hand?
I'm confused on how we're suppose to do the graph. How many are we suppose to have and what should they be about?

Sorry. I didn't mean to put it so many times.
Hi mr smith, i have two questions, since we were unable to get the mass of th seed, should our biomass graph just be dots, or is there a way to make it linear? Secondly, in part 13, It says to record the data in a table and determine the average for each factor that you changed and to plot these averages on a bar graph. What does this mean find the average, what are we finding the average of? My partner and i used different types of water for our expeirment so how does this related to the the factors that we changed, i don't see the relationship between this and the amount of carbon dioxide, water and oxygen that were produced. If you could please explain this that would be awesome! Thanks
I don't really understand what data were suppose to record in a table, there is no reference to it in any of the other question, and i think that i missed something during the project, and that wouldn't be good..anyone that could help..please
I'm having trouble understanding independent vs. dependent variables for question 7- independent would be like time, light, carbon dioxide, water and then dependent would be...? the plant itself? if anyone knows the answer could they plz email me (jam_smiley@hotmail.com)
For question 11, what biomass from seeds or final, then how do we put that aganist time, it wouldnt change because we only measure it those two times, so how would we do that?
In question 9, it says to have tables, graphs, diagrams and picture, how many of each are we suppose to have. I know for pictures it's 1 per week, but how many for the others, and diagrams of what?>
if anyone can answer the 2 questions above that would be wonderful ( i dont think mr smith is going to :S)
Very very intresting to se how many of you do these very large projects just the night before it is due? I wonder about all the time that I offer in class, after school etc for help? I also can see from these comments that many of you do not read the entire project until the last minute. Very very, intresting. The concepts are rather simple. you just have to think for yourselves sometimes. That is part of it being your lab!
Graphs, pictures etc. does it state a number?, or is it simply asking you to have a variety of different formats to show your data to prove your experiment.
As for the biomass of the plant in a graph without the seeds. You can simply make it into a bar graph! It just takes a little bit of thinking on your own some times. Remeber this is your experiment and you must give appropriate data on what you have available.
I hope all goes well while burning the midnight oil, and just read abd think about hte things you would do in a normal lab, and what I HAVE STATED IN CLASSES.
ALL NITE PARTY!!, WHOSE WITH ME?!?!?!? YESSSSSS
well its now 130..happy monday...were going to bed! gOOD LUCK!
hey mr smith, in the dihybrid cross problems #1 b) asks what are the expected genotypes and phenotypes of the f2 generation. in the result of the first punnet square they're all the same (atleast in mine) do we just use 2 of the offspring in the f1 and bread them together for the second punnet square?
thanks, mark
Hi mark. YEs what you want to do is to actually take two of the offspring and multiply them out in the same way to see what the results will be. Same as the examples done in the textbook.
SO you are using the F1 generation to produce your F2 generations.
We weill be taking these up in class tomorrow so try your best.
