Stirring rod

Glue

Borax

Water

Sugar

Salt

Baking powder

Corn meal

Wax paper

Plastic containers

Slime

For the regular slime I put 150ml of water and 1tablespoon of borax in one beaker and 1tablespoon of glue in another beaker. Then I added a small bit of water and borax to the glue and stirred. It was squishy and soft but wasn't sticky. It also could be roled in a ball and bouce if you were to drop it. After that I set it to the side on wax paper. Then cleaned beakers and other materials used. The substance was put in a container.

Slime with salt

I put 1tablespoon of borax and 150ml of water together in a beaker and stirred. Then I put 1/2teaspoon of salt in another beaker with 1tablespoon of glue. Then added the water mixture to the salt and glue (just a little bit). Then stirred and put the substance on the wax paper. The slime was squeezed to get the water out. It was dry and Was like rubber. Did not crumble after it was left for a little bit. Then I cleaned the beakers and other materials again. The substance was put in a container.

Slime with sugar

I put 1tablespoon of borax and 150ml of water in one beaker and 1tablespoon of glue and 1/2teaspoon of sugar in another beaker. Then I put a little bit of the water mixture into the beaker with the glue and sugar and stirred. Then the slime was put on wax paper. It was slimy and extremely runny. Then I cleaned the materials used. The substance was put in a container.

Slime with corn meal

I put 150ml of water and 1tablespoon of borax in one beaker and 1tablespoon of glue and 1/2teaspoon of corn meal in another beaker. Then I added a little bit of the water mixture to the glue and corn meal. Then stirred. It was very runny and the corn meal settled to the bottom and the glue and water was on top. Then it was set on wax paper. Then the materials were cleaned. The substance was put in a little container.

Slime with baking powder

150ml of water and 1 tablespoon of borax in one beaker and 1tablespoon of glue and 1/2teaspoon of baking powder in another beaker. Then I added the water mixture to the glue and baking powder and stirred. It was put on wax paper then in a container. It is squishy but like rubber. It also had lots of water that came out of it after a little while. Then I cleaned the materials.

Research

Sugar is made up of carbon hydrogen and oxygen atoms and is called sucrose. Salt is a natural mineral composed of sodium and chlorine NaCl. Baking powder is made of sodium bicarbonate and one or more acid salts. Cornmeal is course flour ground from dried maize (corn). Borax is a salt of boric acid and is known as sodium borate. Glue is a synthetic polymer.

Conclusion

Independent- corn meal, salt, sugar, baking powder, and water

Dependent- how well the slime turned out

Controlled- tablespoon of glue and each ingredient 1/2 teaspoon

The original slime was the best it wasn't to runny or to rubbery.

The sugar slime was very runny like liquid; the baking powder slime was squishy but also had lots of access water; the corn meal slime was also runny with glue and water on top and corn meal on bottom; the salt was dryed up and rubber feeling as well.

Not making a polymer because glue is already one, but just changing the properties by adding different ingredients.

What should of happened

Plain- role in a ball and bounce

Salt- get hard, break easily, not bounce, and be able to squeeze water out of it.

Cornmeal- kind of like the original but gritty feeling.

Baking powder- not as hard as salt but pretty hard and crumbles also. When mixed should of floated on top of the borax.

Sugar- doesn't form a ball, doesn't bounce, just stretches
