Sherbet experiment

• Today in class we did a science experiment on sherbet using a plastic cup, ice block sticks, baking soda, tartaric acid and citric acid. First we got to try all the different ingredients. The ones I liked was the icing sugar and a little bit of tartaric acid. After we all had to mix all of them in the plastic cup and use the right amount to make the perfect sherbet. We had to add a little bit of baking soda, a little bit of citric acid, a tiny bit of tartaric acid and a lot of icing sugar. I enjoyed this activity because we all got to try disgusting acids (in my opinion) and we got to try baking soda straight and it was fun.

Animal classification

Today we learned about how animals are classified into groups. Animals are either vertebrates (which means they have a spine) or invertebrates which don't have a spine).

Vertebrates are put into five groups. The are mammals, birds, fish, reptiles and amphibians. Mammals have fur or hair and give birth to live young.
Birds have feathers and lay hard eggs. Reptiles are cold-blooded and lay soft eggs. Amphibians breathe through their skin and need to keep their skin moist. Fish breathe through gills and have fins .

5 examples of each type:

Mammals:Cow, Horse, Bear,Dog, Human

Reptiles:snake,lizard,alligators,chameleons and a skink

Amphibians:newt,frog,toad,salamander and a caecilian.

Fish:seahorse,squid,blowfish,shark and a dolphin

Birds:eagle, rooster, ostrich, woodpecker and a peacock.
