Here is one of the videos we watched today about the Olympics:
Do you know what are the properties of liquids? Liquids do not have their own shape. They always take the shape of the container. Liquids can be gooey or runny. On January 16th, we did an experiment with three different kinds of liquids. For this experiment, we put a glob of ketchup, mustard and honey on top of a baking tray. We predicted which liquid would run faster and which liquid would run slower if we tilted the tray. Next, we tilted the tray to see what would happen. At first the mustard was going faster than the other liquids. Then ketchup started running even faster and started reaching the bottom first. It looked like it was going to be a really close race! Some of us thought ketchup would win! Then something unexpected happened. The glob of honey had been the slowest liquid of all but right before the ketchup was about to hit the bottom of the tray, the glob of honey fell down! It landed on the bottom of the tray before the ketchup reached the bottom. We thought the honey cheated in this race. Ketchup was the fastest liquid in the end! We really enjoyed this experiment because it was exciting. Most of us were surprised to see what happened with the honey.
We wrote about our observations and theories together:
Our egg has hatched! The head of a dinosaur is peeking out of the crack. Every day it’s hatching more and more. We think that the dinosaur might be a parasaurolophus or a pterosaur. We think it’s a pterosaur because the head looks the same. Their heads both have a curved shape. We’re not sure if it’s a parasaurolophus because in the book it says that the crest is very long but our dinosaur has a shorter crest. Also our dinosaur doesn’t have a fan that makes the crest go up and down. We noticed that the egg is cracked when it used to be smooth. We think the water might have made the material of the egg softer, and that’s why it cracked. We saw two holes in the egg before we put it in the water. We think the water went into the holes. We think the dinosaur is made out of sponge and is absorbing the water. That is why it is getting bigger. We are very excited about this experiment. We are happy to see our dinosaur growing.
Today we had a class discussion about our water samples. Everyone did a great job listening respectfully to the ideas of others. We were curious and excited!
Mrs Ho: What are you wondering about our water samples?
Stevan: I’m wondering why all the water… I wonder why all the water is the same colour but some aren’t because every water colour is the same but when you put it in a jar it’s a different colour to another.
Student 1: Some of the waters are clean. Mine is dirty so it’s a different colour.
Stevan: All of ours are a little more dirty but some are more dirty.
Lyssie: I was listening to Antonio but some are dirty but some of the bottles are coloured so like pop bottles.
Brant: I’m wondering why all of our water I bet are from a different place.
Owin: I wonder if there are any little animals like plankton and stuff.
Parker: Can we create stuff with water?
Student 2: All of the water samples one of them are like dirty but I’m not sure if Antonio’s is from a lake.
Student 1: Mine is from a beach.
Lyssie: It is from a beach because it has little tiny shells. The little tiny shells I went to a lake that had them and they call them zebra mussels. When they’re not crushed up there’s a thing inside that goes inside water like a mussel.
Mrs. Ho: How might we investigate our wonders?
Chloe: Getting a magnifying glass and look closely in the water samples.
Lyssie: I was wondering my water was cold when I got it but I’m wondering if it would still be cold when I take the lid off.
Stevan: Can we bring it home and if we have a magniscope. We can put it on the glass thing and see if we can see any living bacteria on it.
Our class loves listening to reading! Here are some of the books we listened to this week.
We learned that it only takes one person to stop bullying and to start spreading kindness, and it can begin with us!
