I don't really need help with this assessment, but l was wondering if anyone else here had to catch insects, kill them and answer questions about them?

Oh this is for prelim.

l'm not sure..but its under the topic Life on Earth

My guess is dot point 4..the point on the prac side. In this experiment we have to deisgn a dichotomous key.

Never had to do anything like that, interesting. Umm, did have to use snails for an assignment, but this was yr7 science so I cannot remember the purpose of the snails.

to do a dichotomous key, you need to examine an organism, especially insects, carefully in order to define their features. So yeah, It's weird, but start counting how many legs they have!


And no, i never had the good fortune to do something like that.

oh okay

we got pictures of animals and plants. and did em from that. or we could use real cuttings etc

 

[xiao1985]

we only identified them and did some excercises using diagrams etc...

ARGH!!!! animal cruelty!!! u cruel cruel ppl!!!
and ARGH!!!!!!!!!!!!! bugz!!!!!!!!!

*runs away...

lolz, reminds me of pokemon, when they have all the bug catchers

*shivers* animal cruelty.... why can't u guys just get pictures of bugs n use a dichotomous key with that?? i hate having to dissect things.... specially the eyeball! omg that was toooo harsh... we got cow eyeballs and some of them still had bits of eyelid flesh and eyelashes stuck onto them!!

 

[kimmeh]

we got given the pictures of the insects and then we used that data to constrauct the dichot key.

That was the best prac. I remember people stole them and we had eyeball fights

You can choose whether or not to particate in a prac. on ethical grounds. I'm sure it wouldn't be held against you mark wise.

 

[Misturi]

I have 10 insects now..l think it was more of a challege getting the insects.

I asked him if l would be penalised heavily if l didn't get the required number of insects (10-15) and he said yes.

I found some ones that were already dead, so l didn't feel mean about killingthem because l didn't.

What about if its an assessment?

 

[luckyduck]

hey!! someone please help me! i have to construct model of DNA, consisting between 4& 8 nucleotides? how do i make it and how does it look like??

 

[kimmeh]

DNA model. You dont know what it looks like ?
our teacher gave a a bit of photocopied thin card with the helix on it already and how to glue it together. all we had to do was to cut it out

 

[luckyduck]

hahah i do! know what it looks liek but what is nucleotides?how do i do thaT?

a nucleotide is a sugar+base+phosphate group...

how do u do the T??
um basically connect a base labelled 'T' (make sure this base is complementary to 'A') and link this to a sugar. Now link the sugar to a phosphate... and on u go..

note that there are only 4 nucleotides in DNA, each one consisting of each of the four bases...

hey!! i have to make the dna model! what could i use to make it???
