Compressive strength

 


Today for the experiment I had already done all the prep if you want to see what the the prep was click here. The circular ones ended up also holding my scissors, all the pencils and rubbers. It still hadn't collapsed but I didn't know what else to put on it so I stopped.  I was surprised when the flat ones couldn't even hold the roof, when nano girl did it it managed to hold the roof. I enjoyed this activity.

  1. Hi Molly,

    My name is Zana and I am a blog commenter from the Summer Learning Journey.

    How exciting that we are on our third Nano Girl activity and they're getting more exciting and hands-on every week.

    I thought your video was awesome, I like that you explained the activity and you talked through what you were doing and the process you went through. It is cool to see that you tried multi designs for your column and added multiple weights to see which one was the strongest. I could predict that the round ones would be stronger as they create a stronger structure but the flat paper may have worked better if it was cardboard rather than paper.

    Happy Holidays, Keep up the great work and I hope to see more of your posts over the summer.

    Ngā mihi nui,
