Volume and capacity

Today we started learning about volume and capacity. We explored different bags to see if they were the same or different.


We looked at containers that looked the same but felt different.

We had buckets of water and different size containers and we explored how many scoops of containers we needed to fill another size one.






Experiment during writing time


Today we started by watching a video.



We wondered how we could get raisins to dance in liquid.


Our thinking:


Bea: I think we have to put water on the raisins because the liquid has taken control over the raisins.
Finn: I think we can put fizzy and then put the raisins in because the bubbles will lift the raisins up and down.
Sophie Ag: I think we can get more liquid because if we have less it won't dance.
Zane: I think we have to put water in a cup and raisins and shake it.
Keisha: I think we can put lemonade in a cup and the bubbles might make the raisins go up.
Zubia: I think the raisins were going up and down because there was salt water.
Christina: I think we could put water in a cup and we could put raisins in it and salt and the raisins were dancing in liquid because it is water.
Sam: I think we could put water in a cup and then put the raisins in a cup.
Jake: I think we need to put more liquid in the glass so the raisins can dance.
Ashley: I think that we need to put salt water in it.
Oliver: I think we need to put raisins in the water.
Rose: I think it will be funny because raisins are funny.

WE EXPERIMENTED!!




When we put the raisin in water it sunk. The currant floated. They did not float in normal water.


There were air bubbles all the way around the raisin.


We added vinegar and baking soda to the water.


The water went all bubbly and fizzy.






The raisins and the currants began to dance because there were lots of bubbles around it and it made it float.

I AM A SCIENTIST!

Jake: I know it danced in the baking soda. It will dance if we put baking soda in.
Zane: I know it dances in the baking soda. It will dance if we put baking soda in.
Avia:  I know that the raisins sink to the bottom and to the top. 
Katie: I know
Rose: I know that now raisins bounced like a ball. I saw when we put vinegar and baking soda it fizzes like lemonade. The big one sunk like when you put a stone in water.
Greer: I know
Harrison: I know how to make raisins dance by first you put some raisins and put salt and vinegar in 
Jayden:  I know the raisins can dance because we make bubbles.
Silke: I know when we put the raisins in the water sunk because it has bubbles inside it.
Zubia: I know when we put the currant in the water it was floating because it was light.
Finn:  I know now that you need air bubbles to make them float.
Sam:  I know raisins float in water because bubbles made the raisins dance and if we put raisins in tea it probably will float. 
Jun:  I know
Christina: I know that the raisins dance in soda because there was lots of bubbles and it was pretty cool because it was cool when we saw bubbles.
Liam: i know that if you put raisins and currents in a glass the currants will float like the were out in sea but the raisins will float too.
Bea:  I know that when we put the currants in water it will float because of the bubbles. The raisins danced like a ballerina because of the bubbles.
Ashley:  I know that when we put the currants
Te Paea:  I know
Sophie Ad: I know that if we put raisins in water with baking soda and vinegar it will look like the raisins are dancing.
Oliver:  I know that the raisins danced because the vinegar was pushing it with the bubbles like a ballerina. 
 Sophie Ag:  I know that the bubbles on the raisin popped when it got to the top like bubbles in a cup.








Getting ready to share our learning.

We have been working very hard this week getting ready for our student led conferences. We can't wait to share our learning with our family.






Floating and Sinking Eggs

Today we put an egg in water and it sunk.



We wondered how we could make the egg float in water.

Bailey: I think we could put it in a paper boat.
Rose: I think we could crack it because the stuff inside is lighter.
Keisha: I think we will have to crack the egg open because yolk floats on water
Oliver: I think we need to crack it open so it can float because shell doesn't float
Finn: I think if we tie a piece of paper to a piece of string and make a parachute.
Sophie Ag: I think we could make it light by cracking it.
Christina: I think we need to get less water because we have lots of water.
Liam: I think we might have to get a bigger bowl of water and then put the egg in the bowl.
Jayden: I think we need to make the egg little because it will float.
Bea: I think that we have to crack the egg because the egg will get lighter.
Zane: I think we have to take the inside out because the shell is lighter.
Jun: We need more water.
Greer: I think we will have to crack the egg because the stuff inside is lighter from the shell.


We experimented!!!!

We discovered:
  • If the egg is in a container or a boat it can float.

  • When we put it in a bigger bowl of water it still sunk.

  • The water pushed it down.

  • When we cracked the egg it sunk.


  • When we put the egg in plain water it sunk.

  • When we put the egg in salt water it floated.



  • When we put it in a container with salt water at the bottom and plain water at the top, the egg floated to the top of the salt water. So it floated in the middle of the glass.



I am a scientist so now:

Bea: I know that when we put an egg in plain water it will sink. If we put an egg in salt water it will float because salt water is heavier than plain water. The salt water in the ocean can lift an army boat, a regular boat and a ship because of the sea salt.

Zubia: I know when we put an egg in salt water it floats. When we put an egg in plain water it sunk because plain water is lighter than salt water.

Jayden: I know the egg will float in salt water because the egg did not float in plain water.

Jun: I know the egg will sink in the water.

Bailey: I know a boat can make an egg float on the water.

Sam: I know that the salt water lifts the egg up because the salt water is heavy and the egg might not float in a washing machine because a washing machine has got plain water.

Oliver: I know eggs float in salt water because it is heavier than the egg.  Just like a surf board because if salt is not in the water the surfboard will not float.

Avia:  I know we put plain water in the bowl and then salt water in the bowl and we put the egg in the cup and it floated.

Silke: I know when we put the egg it plain water it sinks because the egg is heavier.

Harrison: I know if you get a bowl and some water and put the water in and put an egg in it and the egg will sink.

Sophie Ad: I know that if you get a cup of water and put salt inside it and then put an egg in it the egg will float because salt water is heavier than the egg like the sea.

Liam: I know that if you put salt water in the bottom of a cup and plain water at the top the egg will go through the plain water and it will float when it gets to the salt water.

Rose: I know that now salt water and plain water floats like a ship. If you put the egg in plain water it sinks like when you put a shell in the water.

Te Paea: I know the egg sinks like a ship and like a boat.

Greer:I know that now we can do it at home if you don't have the ingredients then go to the supermarket.

Katie: I know that now it floats.

Keisha: I know when we put an egg in salt water it floats. When we put an egg in plain water it sinks because plain water is lighter than salt water.

Jack: I know the egg was heavier than the plain water and the salt water was heavier than the egg.

Zane: I know that an egg floats in salt water and if you put it in plain water it will sink. An egg floats in salt water because salt water is heavier than plain water. An egg can float like a can. It sinks in the plain water like a piece of paper.

Finn: I know that you need more string.

Sophie Ag: I know when we put eggs in salt water if floats. When we put it plain water it goes down to the bottom because an egg is heavier like an elephant.

Christina: I know the egg sinks in salt water and when we cracked it the yellow part came out and the yellow part is a little bit like a soccer ball and it was exciting when we cracked it.

Ashley: I know that the water it can lift up a plane.
