Materials:
Procedure:
Safety:
Some of Scotchgard hazards include:
Any left over magic sand will be thrown in the trash, and the bowls will be wiped clean. We will also make sure that the scotchgard didn’t get on anything.
Documentation:
We will be taking pictures throughout the entire process. We will also take notes on what is happening and why we think it’s happening.
Science:
Magic sand is a toy made from sand coated with a hydrophobic compound (scotchgard). The presence of this hydrophobic compound causes the grains of sand to cling to one another and form cylinders (to minimize surface area) when exposed to water. When the sand is removed from water, it is completely dry and free flowing.
Hydrophobic compound: "A 'water-fearing' compound, such as oil, that has low solubility in water and tends to form a separate phase."
Looking Back:
In class we got to make magic sand. It was so much fun to make and it was a little messy. For this project worked with Lydia, Morgan, and Genevie. They were really helpful to work with, because they knew what they were doing. Making the magic sand was fairly easy, because we just needed a few ingredients, and all we had to do was mix them up. When we were working on the magic sand I had a feeling that we didn't add enough scotch guard. Once we added water, it seemed to work and the sand came out dry, but a little after the sand kept getting wet.
Looking Beyond:
The experiment we did was pretty simple, but the chemistry to magic sand was not. As I expected there is a lot of chemistry in magic sand. Magic sand is a toy made from sand coated with a hydrophobic compound (scotchgard). The presence of this hydrophobic compound causes the grains of sand to cling to one another and form cylinders (to minimize surface area) when exposed to water. When the sand is removed from water, it is completely dry and free flowing. While doing the experiment it is helpful to add the correct measurements, so that way nothing goes wrong.
Looking Inward:
The project didn't turn out the way I expected it to work. I thought that the sand wouldn't get wet at all. I think the project didn't work out, because we didn't add enough scotch guard. Another way we could've improved is by following the measurements. Overall my group worked really well together, and the project was ok, we just didn't get the results we expected.
Looking Outward:
While doing this project I worked with Lydia, Morgan, and Genevie. I have worked with all of them before, and I think we all worked really well together before, so we decided to work again this time. It was really fun to work with everyone, because everyone was helpful and fun to work with. Everyone contributed to the work, because we all took turns adding the scotch guard, and we all helped getting the materials for the project.
Looking Forward:
The experiment was really fun to do, but it didn't work out the way I expected it to work out. Even though the magic sand didn't work I think that it was still very fun to play with. If I were to do this project again I would probably try to add a lot more scotch guard, because the sand didn't come out dry from the water, and that determined that there wasn't enough scotch guard. I don't really see any other way to continue this project on.
Take Away:
Making magic sand was a simple but fun project to do. To make it all you had to do was place the sand in a small bowl. Evenly spray the surface of the sand with the waterproofing chemical. You may need to shake the container of sand to expose untreated surfaces. Put enough scotchgard to give the sand a wet to dry appearance. Do not drench it. Allow the sand to dry. Pour the sand in water and record what happens. It was a really fun project to do with my friends.

Materials:
- Sand
- Scotchgard
- Gloves
- Water
- 2 Bowls
- Food Coloring
Procedure:
- Place the sand in a small bowl.
- Evenly spray the surface of the sand with the waterproofing chemical. You may need to shake the container of sand to expose untreated surfaces. Put enough scotchgard to give the sand a wet to dry appearance. Do not drench it.
- Allow the sand to dry.
- Pour the sand in water and record what happens..
Safety:
Some of Scotchgard hazards include:
- Extreme flammability
- Can cause drowsiness or dizziness
- May shift the oxygen in a room and cause suffocation
- Do not smoke when applying it
- Do not spray it onto flames or other source of ignition
- Do not breathe its dust, fumes, mist, vapors, gas or spray
- Always use in a well-ventilated area or outdoors
- Dispose of containers safely; do not throw them into a fire or pierce the container
Any left over magic sand will be thrown in the trash, and the bowls will be wiped clean. We will also make sure that the scotchgard didn’t get on anything.
