Matter Matters
Define: challenge was to inform people about matter in an engaging way.
Dream: PowerPoint, Presentation, kahoot, poster, video.
Design and deliver: we made a PowerPoint presentation and we delivered it over edublog.
Debrief: we worked as a team and found ways to present in an entertaining way. Creativity of presenting could have been a bit more interesting. But otherwise it was a very effective in teaching people.
Oobleck
We did a experiment in science we made Oobleck. Oobleck is made up of two things. Chemical A was a transparent and clear liquid. Chemical B is a white, powdery, thick, and clumpy substance. The properties of Oobleck are a creamy colour, liquid, and solid. The Oobleck acted like a solid when hit fast and put under pressure quick but when it slowed down it turned into a liquid so Oobleck behaves both like a solid and liquid. I think Oobleck is liquid because Oobleck only holds it solid form for a short period of time not majority of the time. It helped me understand that molecules can act in different states when put into it but will reform back into its original state.
