Ice Science

Kia ora bloggers.

For our writing the last few weeks we have been working on experiments that include melting ice. And this week we worked on what powder could eat away at ice the quickest. We knew that salt sprinkled at ice would melt it. Part of that was making a doc with a wondering, hypothesis, materials, variables, procedure, observations/results and conclusion. We did the experiment and somehow salt did it the quickest. here is my working out.
































Thank you for seeing this blog post. The science behind this was really interesting.

If you have ever done an interesting experiment please comment down below.

Super Spark

Oil is in and around our world, even in places you wouldn’t imagine. We use oil for cooking but we also use crude oil. The pumping and transporting of crude oil around the globe often have environmental effects. We have looked at various texts and videos to learn about some of these effects, and it ‘good’ timing as there was a recent oil spill (24 July 2020) in Mauritius that we could investigate. Check out my video to learn more about oil, and see the simulation we did in class about cleaning oil from water. Here is my adobe spark 














If you have learned anything please comment down below of what it was?

Disappointing Parachute`

Kia Ora Bloggers

For or inquiry this term we have been working on engineering and our task was to answer some questions and this is it. We used String 2 bolts Green fabric cut on corners. We had a fairly big parachute it was 40 cm long and 32 cm wide we made it fairly big because that increases drag, and it will fall slower. We thought that we should add more fabric on the top but we realised that would make it heavier. Our design fell in 1.05 seconds, which isn't very good.  Here are some pictures.

We added more fabric on the bottom of the parachute so it keeps its shape.  When falling. We saw it fall slower, before we changed it it fell in 1 sec .5 when we changed it it fell in 2.00 seconds. We changed it one more time and added more fabric 1.44 it did bad so we took the new fabric off.
