Step 6 Continue building your second tower, being very careful not to apply too much pressure on the top. The last step is to add the keystone, which is the last handful of sand you’ll use to construct your arch and will hold the two halves together. To make your keystone, simply add a handful of sand between the two sides and carefully mold them together until they form a solid piece. Have you thought why your tent pegs sometimes don’t stay in the ground when it’s windy? Using what you’ve learned today, next time you can think if it’s the way you put them in or the ground you put them into. Piles are usually found under tall buildings, or where the soil is weak. They spread the weight of a building or structure evenly across the depth of the soil. Engineers know the top of the soil won’t be able to hold much of the building’s load and the friction created on the edge of the piles helps spread the weight into the soil. This type of foundation has been used under the building called The Gherkin in London, which you may have seen. It’s OK if not everyone wants to share their ideas or talk in front of the group. If people aren’t comfortable sharing with the group, people could get into pairs or small groups to chat about what they’ve learned instead.

The best sand is usually below the tide line, which is also a good reason not to build too far from the shore. You want to find moist sand that will hold together firmly when you roll it into a ball. If the ball of sand rolls around in your hand, then you’ve found the right stuff! 3. Dig Your Water Hole Building sandcastle walls will likely take the most amount of time to complete. But the more time you take, the more sturdy you can make sure each castle wall is. This activity may have inspired you to be an engineer of the future, who uses this knowledge to build bigger buildings or create structures on less desirable material. It simply might help you to win the next sand castle building competition, too.When building a sandcastle, you’ll need to have a constant supply of water on hand. The best way to have easy access to water that doesn’t involve frequent trips to the ocean is to dig a water hole, which is easy to make. All you have to do is start digging in the wet sand and don’t stop until you reach the water. Now, add the same initial weight to each sandcastle. You could keep adding weights until the sandcastle collapses to see which holds the most.

If anyone doesn’t feel comfortable touching or putting their hands in the sand, they could put the weights on the sandcastles or wear gloves instead. Step 5 Moisten as necessary. The longer you work on your composition, the more your sand sculpture will dry out – you must keep it moist. Tell everyone that they’re going to do a few simple, but messy, experiments to understand how to create a solid foundation for building on. If you're building at the beach, the best way to obtain an unlimited supply of H 2O is by digging a self-replenishing water hole. Start digging.Beginners should keep towers close together at first. Once you have mastered the technique you will be able to span larger areas. Every day, we rely on the ground beneath our feet to be strong enough to stop buildings, roads and yourself from sinking into it. Remember, everything we build is put on the ground. Therefore, engineers must think about the type of soil that they’ll build something on and how heavy something they are going to put onto it is. In this activity, we learned about the different ways engineers can make sure buildings are stable, solid and secure. Now it’s time to tidy up. Make sure it’s shared between everyone, so they can work as a team – just like the grains of sand. Make sure you’ll have enough adult helpers. You may need some parents and carers to help if you’re short on helpers.

Step 5 While the sand is still moving, put your hands on the edges of the sand pancake and continue vibrating the sand. Once the water has run through and the sand is no longer moving, stop. Don't pound on your sand pancakes; let water and gravity do the compacting. Only jiggle freshly placed wet sand. Once the water has run through, the pancake becomes fixed in place. If you jiggle it you will break the bonds that are holding it together. If needed, let people be in bigger groups to make sure everyone’s supported in taking part in the activity. A young leader could join a group to help people to take part, too.
The magic formula
Step 2 When you reach the height where you want the arch to begin, scoop a handful of wet sand, and … Use lots of water. Dry sand in its natural state is lazy stuff. It wants to lie down and spread out into all sorts of nooks and crannies. The good news is that as long as you keep gravity working for you, there is really no way to add too much water. Which brings us to our second rule. The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. Now that you've built some walls and towers it's time to pretty them up. Here are some basic rules: Step 3 … positioning your other hand as a support next to one tower, plop your handful and jiggle so that it slops over the edge in the direction of the other tower.
