science this year!!!
this year my dad (brent), is teaching hannah, aliysa, me, eliza, and jace all science! we're really excited for biology and all the fun things that go with it, the microscope, all the experiments and well... mabey not so excited to cut open giant frogs, but of course having fun writing down all of our fun adventures here!

members in the science lab:
1. dad/brent as BioDomin = life master
2. Hannah (yet to be decided)
3. Aliysa as Animalia = animal kingdom 4.Vanessa as Tameanea = latin name for butterfly
5. Eliza (yet to be decided)
6. Jace as Fungi = fun guy


In this module we
learned about the 4 criteria of life, which is what a life form has to pass in order to be considered alive
. it must have DNA which is short for deoxyribonucleic acid!
. it must reproduce
. it must react to things around them
. and it must be able to convert energy to food

we also learned about once you know their alive how to know what they are or be able to use taxonomy: the science of classifying organisms. we learned to classifying them into things like herbivores, animals that eats only plants, carnivores that eat only things other than plants, and omnivores, animals that eat both plants and other organisms. Or into producers, organisms that produce there own food (mostly plants), consumers, organisms that eat producers or other consumers, and decomposers, organisms that break down dead organisms for food. autotrophs or heterotrophs if can or can't make their own food, or into the eukaryotic cells group or the prokaryotic cell group weather or not they have distinct membrane - bounded organelles or not.
Then there's the 5 kingdom classification system, thats what you use if you want more information or more details than the classifications above can give you. the 5 kingdoms are Monera, Protista, Fungi, Plantae and Animalia. the 5 kingdom system has several different levels down from that depending on how much information you want. the first level is kingdom, second phyum, then class, next after that is order, family, genus, until last is species.
a fun and easy way to remember this is with this funny sentence we learned "King Philip Cried Out, 'For Goodness Sake!" :) now we'll never forget which order they go in!
we had a chance to classify using this method with the help of a biological key. that was a lot of fun finding there name and then trying to pronounce it!
last in this module we learned about another newer classifying method similar to the 5 kingdom system, it was called the 3 domain system in which there were the domains Archaea Bacteria and Eukarya. in this system you classified all the organisms with eukaryotic cells in the Eukarya domain and the prokaryotic celled organisms in two different domains. the ones that lived in extreme environments went in the Archaea domain and the ones that didn't live in extreme environments went in the Bacteria domain. this classifying system is mostly used by evolutionists.
