What are the casting defects in this?

We have a course on Casting and Solidification. We had to prepare an Aluminium cast for the lab work

- The pattern was created using thermocol/styrofoam

- The mould was created using plaster of paris and water. After it dried out I removed the pattern by hand and there were not any visible cracks or damages as such. It was left for around 3-4 weeks for drying after that.

- There was no gating system although their was one cast which seemed to be perfect without any gating system somehow aswell.

- Before casting i put the mould in an oven for 3hrs and then 15 minutes of blowtorch on it. After that Aluminium melt was poured into it

For viva, our prof has told us to analyse the cast and talk about all the defects present in the cast and why it has formed

Im guessing the large one, its a blowhole but im not sure enough. Please help with it. Thank you! The last 2 photos are the pattern and the mould. I'll be attaching a video of the cast and the mould in the comments if its possible.

How do you find good project ideas without it being just a gimmick to fill your resume?

I'm currently doing B.Tech degree in Metallurgical and Materials Engineering. I'm in 2nd Yr. The issue I'm facing while searching for projects is I find a lot of ideas but I'm unable to filter out which is actually useful or interesting and good to go with and which are just resume fillers.

For example, right now I had an idea to make a Phase Diagram Analyser that would give the phase composition and phase %age at certain temperature for alloys and all but idk if its useful to invest time after that or its just not impressive at all. Similar thoughts for another one I thought to build a device that can measure the thermal conductivity of materials but again there are already a lot of them, will it be of any use if i build one as a project?

[Student] How do you find good project ideas without it being just a gimmick to fill your resume?

Just read the wiki, under projects it says

>If you want your projects to stand out, they should be real projects, not mandatory school projects or trivial tutorial projects found online. Something that someone uses to solve a problem.

Year back doubt

If one passes in the supplementary backlog exam in atleast 2 papers who has 5 backlogs total in 1st 2nd sem combined. Will he/she still get a year back?
