Science Experiments

For science has been learning about the water cycle.  We did five experiments. One was about the air pressure inside of a balloon and another one was blowing up the balloon then dunking it in water. It made a big bubble. This shows that there were air particles inside a balloon.  Another was finding out how the air pressure varies each size.

Top secret Experiment Sherbet

Today in science we did a sherbet experiment. The first step we had to try all the ingredients which included baking soda which tasted so salty and disgusting, icing sugar which was the tastiest of all ingredients, citric acid  which was the most bitter and sour tasting and tartar acid which tasted tart and bitter. The we moved on to making sherbet. With my group we tried to create our own sherbet. We added icing sugar first then baking soda then citric acid and finally Tatar acid. We tasted it with a Popsicle it was sour and bitter it didn't taste nice. We added a bit more icing sugar and it tasted better than the last one. When everybody started tasting each other's my group started running out of sherbet so I quickly decided to make so sherbet myself. I put about 1 teaspoon of icing sugar in, about half a teaspoon of citric acid, tartar acid and baking soda. Mixed that together and it tasted awesome. I think mostly everybody liked my version of sherbet. This lesson is taught me that if something isn't the best you can always fix t by using something else or a least make it better than what it was before.

Top Secret Experiment spud gun

Over two experiment lessons in science this experiment didn't quite work. Spud guns are a straw with potato in both sides the point of a spud gun isn't for shooting people in the face but to see who can shoot the furthest. How do the gun's work? The gun's worked by air pressure. You use skewers to push from the blunt end from any side of the. Straw then the pressure builds up and forces the potato out the straw onto the grass. You can make go as far as you want depending on how much pressure is put into the straw but if the potato isn't soft enough for your straw to jab it in the straw will get all damage the straw and the potato won't shoot out as well. I bet some of our class was very disappointing that this experiment didn't work but some things in life don't work out as you expected.

Bird Beak Experiment

Today in Science we did this experiment.  We used these different forceps to pick up lollies, We experimented on how different types of forceps can be better than the others to pick up the lollies. Now how does relate to to bird beaks ? Because the forceps act like bird beaks pick up there food.  The lollies we used were skittles and snakes. We found  different forceps easier to pick up the lollies some forceps couldn't even pick up the lollies. My forcep that I chose wasn't able to pick up or stab the Skittles it was because the beak wasn't wide enough or big enough to fit the skittle and when you stab the skittle it went  flying away somewhere . The good part at the end we got to eat the lollies.

Science

Today in science we  dyed wet paper towels and dry paper. The wet paper combined colors and the dry ones didn't. The 2 colors stood on each side. After lunch we saw  beautiful combined colors flowing around the paper towels. My classmates swarmed around to see the beautiful sight, and that was our science lesson for today.

Animal classification

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

Invertebrates are animals like Jellyfish , crabs ,insects  and octopus.
Vertebrates are put into five groups. They are mammals, birds and reptiles ad amphibians, Mammals have fur or hair and give birth to live young, Birds have feathers and lay hard, Reptiles are cold blooded and lay soft eggs, Amphibians breath through their skin and need help to keep their skin moist . Fish breath through gills and have fins.


Mammals: tiger, cow, spider monkey, pig, bull

Birds: sparrow, trumpeter, puffin, kea, bee eater

Reptiles : crocodile, turtle, tuatara , gecko , komodo dragon

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

Fish: guppy, shark, catfish, trenchfish, snapper 

Science Roadshow

The Science  Roadshow took place on the 21st of June. I was very excited for the day. We traveled there on a bus even though the school was Edendale and it was very close. When we got there the year fives and six's in our school were early. When all the other schools arrived we started the show. The first part was called  the Fire and Ice show. They did a cool trick and pored kerosene over the fire on the candlestick, it was suppose to blaze up but instead it sparked and went out. Then  they put it into a sprayer and sprayed it and it blazed up like the cannons at  Eden Park when the All Blacks score.

At the end there was this challenge. You had this card and you were suppose to go to the green flags and answer the questions, If you got 2 or 3 or 4 punches in your card you would be in to win a prize.
