NOTES


see the video..what are the diet of the dinosaurs?..how about sid then?
can you distinguish? 
let me give you the clue..
the 3 animal's diet characteristic are carnivore, herbivore and omnivore.




CARNIVORE

carnivorous animal are animal that eat other animals or also called as meat-eater animal

 A carnivore is a predator because it has to find and catch its prey. 
Some carnivores, hunt in a group called a pack and some individually find their food alone
there is carnivorous mammals, birds, insect, fish but most reptile are carnivore
can you think of any any examples?
how about plant?..is there any carnivorous plant?

HERBIVORE


herbivorous animal eat plant only. they eat leaves, fruit, seed, shoot and all part of plant according to their preference. some of then graze at grass field, some just climb up and eat on tree and some just use their long neck. what are that long-neck animal?


OMNIVORE


omnivorous animal are animal that eat both plant and other animals. these diet's animals eat fruit, seed and then they also eat insect, fish. usually some mammals and birds are omnivore. we human eat all kind of food..does that fact make us as omnivorous?



so,now can you determine what diet of dinosaurs and sid?..are they carnivore, omnivore or herbivore? 


















Acid and alkali

acid and alkali are one of the properties of substance that existed in our daily life. our food and our daily life activities all contain various types substance and ingredient which have their own properties which is either acid,alkali or neutral. so how can we recognize the acidic or alkaline or neutral substance? 

do you recognize those? 




in those picture, that an indicator that can tell you whether the substance is acidic, neutral or alkaline.


acidic
acidic substance are substance that contain acid 
acidic substance did not change red litmus paper 
acidic substance change blue litmus paper into red coloration

blue litmus paper turn to blue when in contact with acidic substance 


if you can't find any litmus paper, you still can distinguish the properties of substance. just use your tongue!
if the substance that you taste is sour, then they might be an acidic substance.but be aware!!!..do not taste any substance!..make sure it is edible and safe then you can do the tasting. example of acidic substance that we always use in our daily life
vinegar

lemon and it's family (citrus)

alkaline

alkaline substance are substance that contain alkali
alkaline substance did not change blue litmus paper 
alkaline substance change red litmus paper into blue coloration

red litmus paper change into blue coloration


for alkaline you absolutely cannot taste those alkaline substance below


that's all for the topic. we shall discuss about an experiment in this topic next.
