News from Four/Five

In our Inquiry this term, we have been investigating Extreme Weather and have been finding out facts about lots of weather events. We have also been creating experiments based on erosion and volcanoes. We are loving learning about this area of natural science.

Earthquakes - By Quinn

Earthquakes are something that are strong vibrations that ripple through the earth.  There are 9 types of strengths called magnitudes. The lowest is 1, then 1.5, then 2,  and it goes up to 9.  In Japan, there was once a magnitude 9 earthquake. It destroyed a lot of buildings, and only some buildings survived the quake. The ones that made it had moderate damage,  but they were left standing because they were new. 

Earthquakes happen often but in some countries they don't. If a country is not near tectonic plates or on fault lines, it will not have earthquakes. If one does happen, you should go near a doorway and put heavy things far away, but if the doorway is not big enough, you can then hide under a table.

Volcano Experiment - Marlee

On Wednesday, 4/6/25, we did a volcano experiment. We had sparkling water in a styrofoam cup, bicarb soda, red food dye, dish liquid, and vinegar. We had all the dry ingredients and then added the liquid.   It exploded.  I was in a group with Quinn, and we took it in turns. With the stuff for the experiment, I did sparkling water,  Quinn did the bicarb soda, and then we did the vinegar.  Then it exploded on the table, and we made bubbles with the cups. Then we made a mess! 

Tornadoes and wild winds! - Liliana

Tornadoes, sunstorms, hurricanes, storms, and even lightning are some of the topics we have been learning about this week. Some places would have, instead of earthquakes, like some of the other options up there, but there are a lot more natural disasters.

 Volcano Experiment by Arlo

On Wednesday, June 4, we did a volcano experiment, and my partner was Ollie.  This is how we made it. We put sparkling water into a cup, and then we added bicarb soda, and we had to mix it and it fizzed then we added a good squirt of dish washing liquid and then we put red food colouring in and it turned dark red then we put some vinegar and it fizzed out of the cup. We tipped the rest of the liquid out of the cup, and then we flipped it over, and we figured out that you can make bubbles, and when you squished it, the bubbles would come out, and you could blow bubbles with the mixture.

Volcano Experiment - Archer

 On Wednesday, we did a volcano experiment. First, we chose partners, then we mixed the ingredients into a paper cup, and it started pouring out of the cup. It was super fun.

Here are the ingredients and the steps if you want to do it at home: first, you pour sparkling water into a paper cup, then put 3 tsp of bicarb soda, then stir, then squirt dishwashing liquid, then stir again.

Assembly - Henry

Last Friday, the 30/5/25, our 4/5 class presented an assembly.  Blake, Parker and I presented math. We did perimeter, so I was talking about math, and Parker was holding a grid paper, and Blake was measuring. But actually, Blake was not measuring; the measurement was already on there.
