Sherbet Experiment.

Today we made sherbet. The ingredients we used to make the sherbet were baking soda, icing sugar, citric acid and tartaric acid. We also used wooden  Popsicle sticks to eat the sherbet. I was in a group of four. We had measured the amount of ingredients we needed to use. Our recipe was two scoops of icing sugar, 1 scoop of tartaric acid, one scoop of citric acid and one scoop of baking soda. Our sherbet was a success and was not to sweet and not to bitter. It was a really fun experiment and was awesome learning how to make sherbet.

Potato Gun

Today we did an experiment using potatoes. It was called a potato gun. The materials we used was plastic straws, potato's and skewers. The key was to make it air tight. To work the potato gun you had to press the straw in the potato. You had to fill the straw with potato on both ends. Then you had to get the skewer and press the potato from one end to the other. The air pressure would push the potato from the other side and it would go flying out. Unfortunately mine didn't work along with a lot of others.😕

Beaks

Today we did a experiment on how birds get their food using their beaks.  We all split in to groups of six and were given six different types of tweezers to act as the beaks. We used skittles, gummy worms, and paper as the things we need to pick up with the beaks. We made our predictions and recorded them. Our predictions weren't very accurate but it is just prediction. After the experiment we got to eat the lollies. We are so lucky to be able to do this in our leaning.

Science Experiment

This term in science we have done some experiments. Our latest experiment was the wet paper towels and dry paper towels. We had to guess if the wet paper towels would soak up the dye quicker or if the dry paper towels would soak up the dye quicker. We waited until the end of lunch time to see our results. It turns out that the dry paper towels absorbed the dye quicker. The explanation for this is that the wet paper towels were full of water so it was harder for the dye to spread  because the water is stopping it. But the dry paper towels weren't full of water so the could spread without anything getting in it's way. This is a photo of the experiment.

Classification

Today we learnt about how animals are classified into groups. Animals are either vertebrates or invertebrates. Vertebrates are animals with spines. And invertebrates are animals with no spine.

Invertebrates  are animals like jellyfish, crabs, insects and octopus.

Vertebrates are put into five groups. They are mammals, birds, reptiles, fish 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 breath through their skin and need to keep their skin moist. Fish breath through gills and have fins.

Five examples of each type are:

Mammals: Cheetah, dolphins, giraffe, squirrel, rabbit.

Birds: woodpecker, sparrow, kiwi, dove, fantail.

Reptiles: Snakes, sea turtle, crocodiles, lizards, chameleon

fish: salmon, eel, sharks, seahorses, stingray.

Amphibians: frogs, toad, salamander, newts, caecilian.
