Science Project: The Strength of Sand

How strong could a bunch of a teeny-tiny particles be? They’re so small how could there any strength to them. Well, this science project will redefine the old phrase, strength in numbers. Test how strong sand can be and fool your friends and maybe even teachers!

Materials:

  • Cardboard tube from a roll of paper towel
  • Sand can be found at craft or garden stores if not close to beach or desert
  • Sheet of tissue paper
  • Rubber bands
  • Scissors
  • Stick - dowel rod approximately 1 foot in length or a drumstick works well

Procedure:

  1. Cut the tissue into 2 squares with 8 inch sides.
  2. Place the tissue square over one end of the cardboard tube and secure it there with a rubber band twisted around the tissue and tube.
  3. Get a friend to take the stick and see if they can puncture a hole in the tissue paper that’s covering the end of the tube. Should be pretty easy to do so.
  4. Replace the square of tissue paper with a new intact one and secure it the same way you did the last, but this time fill the tube ¾’s of the way up with sand.
  5. Now have your friend again try and puncture a hole in the tissue paper. What’s your hypothesis of what will happen? Are they going to get sand all over the floor or will the force of sand stymie them?

So Much Sand! How Much Sand Is There in the World?Courtesy of projects.math.arizona.edu

What should happen is that the sand in the tube will prevent the stick from piercing the tissue paper. When the stick pushes against the sand, the sand particles respond by pushing against the walls of the cardboard tube much like a plug in the drain of a tub. So even that little amount of sand makes the tissue paper a nearly impenetrable surface.

Gives you a whole new perspective on sand castles, huh? Maybe they are secure fortresses after all!

Have your say!

What do you think would happen if the sand was wet sand? Think about how a sand castle feels and holds it’s shape. How would wet sand change this experiment? Would the sand be stronger or weaker? Share your hypothesis in the comment’s section below!

How do you feel about sand at the beach?

  • I love the warm sand at the beach! I could lay in it all day.
  • I hate sand so much! I don't like going to the beach and getting sand in everything! Ick!
  • My favorite thing to do at the beach is build sand castles so I guess I like sand.
  • I don't mind the sand, unless it ends up in my mouth- ugg that's so gross!

To be brutally honest, this is a question I get asked about all the time... Now being a person who has been into technology for 13 years now - I can see why so many people have gone over to the world of technology now (I mean, we even have Curved 4K TVs now - which look absolutely awesome btw, but that's for me to talk about at another time).  Now it's important to remember that books are still extremely important. Although you can find almost everything on the Internet now - it's still sometimes useful to look in a book (even if that's not very often). So I do still think they have there place, and for people who actually like the authenticity of a physical book and not some thing that is on iCloud or whatever your chosen Online Storage Solution is. With technology moving the way it is these days, it's so much easier to use something like an iPhone, an iPad, or a Laptop (such as a MacBook Pro) to find the information you need. If you was to create a paper book of everything that was available on the Internet - let's put it this way, you'd need a rather large school bag... And rather large muscles!  :devil However, with something like a MacBook Pro (even the 15" Model), it's much easier to carry around, especially as it's much lighter than a lot of books - you can also take notes on it and edit photos and video, and listen to music, and watch films, and use KidzWorld ;) So personally, I'd take my MacBook and iPod Touch 5G (soon to be replaced with a Moto G) around with me all the time, I've had my time of using books. But as I said, other people may have different opinions;3

It's difficult to say because I love TFiOS, I think its a great book and film, but the Divergent series and film also looks good but I've never read/seen them, so I can't really make a refined judgement.
