If chocolate is given to teachers, then amount of homework will decrease.

If the number of leaves on a tree decreases then the number of birds building nests will decrease because ___________________________________. Now try it on your own!

The amount of the leaves will affect the nest of birds because the birds are more likely to make next on the trees that have more leaves. Birds find more shelter in the trees filled of leaves.

If the amount of sunlight is increased, then plant growth will increase. The hypothesis that plant growth increases as the amount of sunlight increases was supported by the data.

Red & blue light are most effective for plant growth, while yellow & green have minimal effect. UV light can damage plants, causing leaves to burn. Growers often use supplemental light to optimize plant growth.

Independent Variable: The variable in the experiment that is controlled and changed to see the effect on the dependent variable. Say your experimenting with the amount of baking soda in a baking soda/vinegar volcano. The independent variable is the amount of baking soda you add.

– The independent variable is the amount if vinegar and baking soda used in the experiment.

The independent variable is the types and size of eggs. The dependent variable is the height the egg reaches. The controlled variables are: The types of cups, zip lock bags, type of vinegar, the time each egg soaks in the vinegar, etc.

Is it safe to eat a boiled bouncy egg? Yes, but it is not the best idea. It will taste like vinegar and most people find that unpleasant. The shell of the egg has been dissolved by the acetic acid inside of the vinegar, and since the egg white is cooked, it’s membrane is rubbery, causing the bounciness.

Cover egg in cup w/ apple cider vinegar. Cover tightly, let sit, each day give it a swirl. You can then put in water w/ food coloring & color inside of the egg & it will fill up again due to osmosis. …

If you soak an egg in vinegar the eggshell will absorb the acid and break down, or dissolve. The calcium carbonate will become carbon dioxide gas, which will go into the air. Soak one egg in vinegar for 24 hours (1 day), one egg for 48 hours (2 days) and one egg for 72 hours (3 days).

2 days later, the outcome is incredible. The egg shell contains calcium carbonate crystals, which are then broken down when interacting with the acetic acid in vinegar. The end-resulting membrane, after the shell dissolves, is also semipermeable and rubbery in texture.

It can take 12-24 hours before a good portion of the shell is removed. A good sign of progress is a white frothy scummy layer on the top of the surface of the vinegar. After a day of soaking you can carefully remove the egg from the vinegar.

When you submerge an egg in vinegar, the shell dissolves, leaving the inner semi-permeable membrane intact. Vinegar (acid) breaks apart the solid calcium carbonate crystals (base) in the eggshell into their calcium and carbonate parts.

1. First get permission to use kitchen equipment and eggs. Then put a raw egg (in its shell) into a bowl and cover it completely with vinegar.
2. Wait two days, then drain off the vinegar. When you touch the egg, it will feel rubbery. Be careful not to break the membrane, and wash your hands after you touch the egg.

Here are some of the items and materials that can be used in the egg drop project:

• Masking tape.
• Balloons.
• Straws.
• Cardboard.
• Cotton.
• Toilet paper.
• Socks.
• Plastic bags.

Instructions

1. Get a raw egg and carefully place it into a glass or jar.
2. Fill the glass with white vinegar until the egg is completely submerged.
3. Leave the egg in the glass for 1-3 days.
4. Remove the egg from the glass and rinse it under some tap water.
5. Examine the egg.

The Science Behind It: The shell of an egg is made of calcium carbonate! When the egg is placed into the vinegar, you see bubbles, which is the chemical reaction of the acid within the vinegar reacting with the calcium carbonate of the egg shell to produce carbon dioxide.

After the nail polish has dried, place the egg into the measuring cup, marked side down so the Crest toothpaste covers half the egg. Make sure the egg does not touch the bottom of the cup. Cover the cup tightly with plastic wrap and leave it in a safe place at room temperature for at least four full days (96 hours).

Glowing Bouncy Egg Directions Add a cup of vinegar to the vitamin powder and then the raw egg. Wait two days and the shell will completely dissolve off of the egg, leaving just the outer membrane. Hold the egg under a blacklight and it will glow!

If you like to play with taste, add a few drops of vinegar while frying eggs or while making an omelette. A few drops of vinegar will change the entire taste of your dish and give it a quintessential acidic twist. You can also use it for sautéd veggies.

The Glowy, Bouncy Eggs experiment introduces students to the chemical properties of eggs and shows them how a chemical reaction between the acetic acid in vinegar and the calcium carbonate of the egg shell results in a rubbery egg.

Leave the egg in the water for 24 hours. The water will migrate from the side of the membrane where water molecules are abundant (outside the egg) to the side where water molecules are less abundant. After 24 hours, the egg will be plump again.

When you put the egg into pure water, some of the water molecules from the solution move into the egg and the egg swells up. You can tell this happens easily if you use food coloring because the egg will change color. You can also observe that the egg is slightly bigger than the untreated egg.

When enough salt is added to the water, the saltwater solution’s density becomes higher than the egg’s, so the egg will then float! The ability of something, like the egg, to float in water or some other liquid is known as buoyancy.

Soaking an egg in vinegar and then sucking it through a bottle is like two experiments in one. By soaking the egg in vinegar, the shell — which is made up of calcium carbonate — gets eaten away, leaving the membrane of the egg intact. Both experiments can be done with raw or hard-boiled eggs.
