Moon Craters

Have you ever wondered about the moon?

Wondered why it seems to change shape?

Wondered what the moon surface is like?

B4 have been finding out about the moon.

This week we talked about the craters on the moon. 

We did an experiment to find out how the different-sized craters may have formed.

We used a tray of flour as the moon's surface, and dropped a variety of balls onto it.

We were surprised when the little marble went in deeper than the big ball!

Why might that have happened?

Can you see the patterns left in the flour by the softball?

Do you have an interesting fact about the moon to share with us?

Do you have a question about the moon?

Our River Walk - Looking at Fish Habitats

As part of our science work on Fish, we walked to our river to think about fish habitats.

In our river we have trout and eels.

We also wanted to see how people may have changed the river and possibly affected the fish habitats.

Would some fish like the shallow, swift parts of the river?

We checked out a stream that flows into the river

Would some fish like the deep, shadowy parts of the river?

Fifty years ago, this part of the river was a deep swimming hole. 

Now it has filled with silt and stones.

Would the fish swim here?

Could landslides affect the fish in the river?

Sometimes the river floods over this paddock.

Would fish swim here?

'

This bank has been shaped and replanted.

Could this affect the fish?

Would fish like to hide among these boulders?

Did you spot any fish while you were on the swing bridge?

If you were an eel, what part of the river would you live in?

Fish

In science the class are finding out about fish.

Establishing prior knowledge:

Examining one of the hoki which was kindly donated to us by a fishery in Westport:

(thanks to Ros for completing the dissection after school for us, so we could cook and eat the fish the next day!)

The gills:

 The backbone:

Fish have teeth:

Have you ever been fishing?

What did you observe when you looked at the fish?

I Wonder, I Notice, I Predict ...

This term our big idea has been 'Fun, Play, Celebrate'.

 We have had lots of fun doing science experiments and having fun as we learn!

Some of the experiments we did included - 

debating whether oobleck is a solid or a liquid ...

 looking at physical changes when we made 

ice-cream in a bag ...

observing changes when marshmallow is heated ...

observing chemical reactions when we made a 

lava volcano ...

and creating chemical reactions using red cabbage and substances such as lemon juice, dishwash liquid, vinegar and toothpaste.

Can you suggest another experiment for us to try?
