The hypothesis is that the larger size of sand will make the strongest brick.

You will make bricks using two different sizes of sand, then test them for durability, weight, and compression.

You will need 4,536 kg of #8 and #30 silica, 4,536 kg of Portland cement, 9,072 cc of water, a wheelbarrow, a shovel, a mold, a small can of oil, 4,536 kg of weights, a bucket, and a compressive strength tester.

The results showed that the larger size of sand (#8) was stronger than the smaller size (#30) in all tests except for one. The average strength of the #8 silica was 6,610 kilograms in the Compression Test, while the #30 silica was only 4,280.6 kilograms.

This science project is interesting because it shows how the size of sand used to make bricks can affect the strength of the bricks.

Variations to consider include testing three different types of the same kind of brick to find out which is the strongest, and testing the bricks to see which one holds the most water or moisture.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
