EDMON- surface tension 2

We experiment with surface tension again

My family and I experiment with surface tension again.

We put water into the petri dish and threw pepper on top. I saw the pepper floating, I could imagine the pepper is like the water atoms holding onto each other. I dropped the soap into the petri dish. The pepper shot across the petri dish. It was so strange to see this happen. The pepper symbolizes the water tension, so when we added the soap to the petri dish it weakened the water tension, and that is how the pepper shot across the petri dish. 

How cool is this!!

Surface tension

The surface tension experiments:

For these experiments, we will need - 

• A petri dish
• A pipette 
• A measuring cup
• A peace cardboard
• Two coins ($2)
• Dishwashing liquid soup
• Hand soap
• Pepper (fine)
• Water

The first experiment was interesting. My dad told us to observe carefully, or we might miss the results.

I filled the measuring cup to the top. I had to be careful not to spill the water. My sister used the pipette to add water to the cup. She added one drop of water at a time. She stopped adding water, but my dad encouraged her to add more drops. So she added a lot more drops before my dad stopped her. What we saw next was amazing. The water was making a bubble over the top. It surprised me how many drops my sister added and it didn’t spill. I did the experiment too.

This is what we saw.

Bee sting: lockdown

Bee sting: lockdown

It was about a week ago when my sister and I were playing outside climbing trees. I jumped off a tree
trying to run away from my sister. My dad mowed the lawn earlier that day. So, when I jumped off the
tree I landed on a dead bee. As soon as the bee stung me I knew not to walk on my foot so that the
poison doesn’t go into my foot.

I shouted out: ”Dad I got a bee sting!”. My dad took a sharp knife to remove the stinger, but it didn’t work.
My mum got my dad the tweezers and my dad got the stinger out by pinching the front end of the stinger
with the tweezers. 

I will not lie, I felt nervous about the bee sting and the poison. I relaxed after my dad removed the stinger.

I wanted to see how the stinger looked under the microscope. So my dad helped me and this is what we
saw. 

bike riding: lockdown

Bike riding: lock down

Two days ago my sister and I decided to ride our bikes. I did a few skids on my bike.  My dad lifted my sisters training wheels so she could learn how to ride a bike with two wheels.

While I was riding my bike on the grass, I managed to break the left side pedal. I  don’t know how it happened, but my dad fixed it. The next day my dad and mum took us for a ride on the street. It was amazing, because I could finally ride fast. I like to go outside with my bike. I felt good after riding my bike for about an hour.

Exercise is important, and riding my bike is exercising.

Science experiment: The chemistry of winter

Science experiment: The chemistry of winter

My sister and I belong to a science club called Mel science. We receive a chemistry set in the mailbox
each month. Last month’s set included “fake snow” and “snow on a tree”. We did the “snow on a tree”
experiment yesterday, and this is how it went.  

The experiment included tap water, hot water, table salt, potassium ferrocyanide, a paper tree, a beaker,
a pipet, a petri dish, a vial and liquid soap. 

First, we mixed the potassium ferrocyanide with the table salt. Then my mum poured some tap water into
the vial. Now my dad had to shake the vial extremely well. Next my dad put the vial into the hot water for
five minutes, after the five minutes where over he poured the mixture into the petri dish. We put the tree
into the petri dish, we left it for 12  hours. It amazed us at how it looked. Because it had fake snow all over
the tree!!! You might wonder how the snow got on the tree… Well, the tree sucked up the mixture the
same way a paper towel sucks up water. After the liquid mixture (now on the tree) dried out, it left only the
salt crystals. This is the “snow” that was on the tree! 

 

We looked at the salt crystals under the microscope, and this is what we saw.

Kawa of Care Assembly - Draft Writing

WALT understand' kawa of care'. WALT write a recount about our assembly experience.

Check out my draft writing...


Two Fridays ago my class and I had an assembly called kawa of care. At the beginning our class did some dance moves  ***** dancing into the whare to music. I did the moon wake.In my group there was Larell, Kaydee, and me. Our assembly was in the hall. Then it was my group’s turn, and I was nervous and I also think that my gourd was nervous too. Larell, kaydee and me crashed into each other throwing books into the air the audience was *** laughing, and thought  they were real chromebooks. Before our group chase,Mihi and KODA had their play. Their play was called no food or drink near your device. After chase said ‘’ I wonder what will happen if we eat near our device’’ then there was a video played on screen. The video was them doing the wrong thing they were eating and drinking by their chromebooks and there was a cool sound evict on it, at the end we shouted out follow the kawa of care!  I felt macfixit, wonderful and fantastic.                     

Tips CONSERVE WATER

We are learning about the severe drought in the Far North and are learning how we can conserve water in drour community.

I learned that there is a server in New Zealand.

I read the northland redional council pamphlet on how to conserve water.

People have been bathing in the lakes because there low on water very low.
