Kids Science Project Idea – Green Eggs

admin — Fri, 04 Jun 2010 15:03:08 +0000

This science project is unique as you will turn an egg green but how it happens is very interesting and a great demonstration experiment.

Things you will need for the science project.

An egg Red cabbage A pan A pot A bowl Oil A parent to help

You are going to make a green egg and cook it, but you will not be using any food coloring or anything green. Let us get to the experiment and we can discuss the results and hypothesis later.

Take the red cabbage and cut into slices as if you were making cole slaw. You will not need a great deal of cabbage. A cup or two should do the trick. Place the cabbage shreds into the pot and pour in a cup of water. If you are using more cabbage you may want a little more water. You do not need a lot. Turn on your stove top and leave on high or a fairly high heat. Let the cabbage cook for a bit. This could take ten to fifteen minutes. You want to get the water to turn a nice purple red color from the cooked cabbage. We will then use the water from the cabbage. Once the cabbage has cooked and the water is a very dark purple color you are ready.

Take your fresh egg and crack it. Separate the yolk into a small bowl and the white into a little larger bowl. Now take a spoonful of the red water from the cabbage and put into the bowl with your egg white and use the spoon or a fork to stir it up.

Heat up your skillet or pan and place a small amount of oil in the pan as you will be cooking the egg and need to keep it from sticking. When the pan is heated pour the colored egg white into the pan. You will notice the egg white is green. You can also put the yolk on top of the egg white now to cook both together.

This will be cooked sunny side up because you do not want to flip it over as you want everyone to see the green coloring. When done you can obviously eat the egg. There is nothing wrong with it because the coloring was added by the cabbage.

Why did this happen? You took the purple coloring from the cabbage and put it in the egg white and it turned green. You did not have the yolk involved in this. You only added the yolk after the white was cooked to finish the complete egg.

Why did this green coloring happen? What chemical process occurred? Was there any change in the egg shite itself?

This is a great science project for chemistry class in high school.

Tornado Science Fair Projects

admin — Thu, 20 May 2010 20:51:57 +0000

Creating a tornado science fair project has been quite popular at science fairs. Of course, it isn’t possible to create a life-sized tornado for obvious reasons! However, miniaturized versions may be created using simple models like the one about to be demonstrated. It is to be remembered that proportions matter a lot, while creating the models. Therefore, these exact proportions need to be followed. The following is possibly the simplest tornado science fair project that can be made with daily household materials. This experiment demonstrates the formation of the eye of the tornado – the central zone of calmness known as the vortex – within ordinary bottles.

The tornado science fair project requires simple ingredients:
- Two large bottles – the larger the better. Soft drink bottles made of plastic are recommended.
- Water colored using food coloring. The lighter the color is, better the demonstration will be. Glitter dust or confetti result in a dazzling display.
- A drill.
- Duct tape and silicon caulking.
- A steadily spinning surface, an old record player if possible.

The apparatus can be set up quite easily. The first step of tornado science fair project is to make half-inch wide holes at the center of the caps. These caps may then be joined together using the silicon caulking, keeping the holes connected. The bottles may be filled with the colored water now. The second step of the tornado science fair project is to attach each end of this double cap to each bottle. Finally, the two caps may be firmly fastened using the duct tape. The entire apparatus takes a shape and form similar to that of an hourglass.

Now, the entire apparatus of the tornado science fair project may be placed upside down, the bottle with the water being at the top, on the spinning surface. It will be observed that as the water slowly drains out to the lower bottle, a vortex is formed in the midst of the spinning water. This vortex is similar to the structure of the vortex formed inside a tornado.

Precautions to be taken during this tornado science fair project are few, but important. The joints must be made perfectly airtight, so that there is no leakage of water and air bubbles don’t enter the bottles. Moreover, the spinning surface must have a steady motion. Otherwise, the entire rhythm of the tornado would be disrupted. The steps are few; however, are important in a tornado science fair project.

The project, as it stands, is a very simple, elegant, and elementary science fair project that judges see all of the time. What you must do in order to stand out is to make this project a little bit different than everyone else’s science fair project. The fact is, with a project like this, you won’t get a really stunning A+ grade simply because this project didn’t involve too much individual thinking. However, by taking this model as a start and exploring some related concept or by looking at some specific aspect of the model, you can really earn a fantastic grade, and maybe even win the science fair with this simple tornado science fair project.

5th Grade Science Fair Project Idea

admin — Sat, 10 Apr 2010 17:20:40 +0000

It’s that time of the year again! Time to create, design and carry out a science project for the school science fair. Stumped? Don’t worry this article will help you plan a 5th grade project in science.

Here is a great 5th grade science fair project idea:

Every 5th grade project in science needs these important sections: title, materials, purpose (of the experiment), hypothesis (what you think is going to happen), procedure, results and conclusion. For this 5th grade science fair project idea:

Title: Come up with your own title!

Purpose: We all heard the saying water and oil do not mix. Why? Water and oil are both liquids and should mix like liquids. What will happen when we actually test this saying and mix oil and water? What will happen when we mix honey in? What will happen when when place objects in this mixture?

Hypothesis: This section is for your predictions. What do you think will happen when you pour the liquids in the jars? What do you think would happen to the objects? When you place objects into water, they usually sink. Do you think this will happen when you place objects in liquids that are not water? Don’t worry about being right! Hypothesis can be wrong, after all you need to do the experiment to find out.

Materials: For this science fair project idea, you will need

honey small objects of different weights such as paper clips, coins, toys, marbles, etc. two different jars that are at least 8 inches tall water vegetable oil food coloring

Procedure:

Pour honey into one jar so it is 2 inches high. Food color the water (pick whatever color you like best!) and then pour 2 inches of water into the same jar with the honey. Then add oil to the same jar, 2 inches high again. Pour the liquids in reverse order in the second jar. (oil, water, honey) Put the objects in one jar. See what happens to the objects after 10 minutes, one hour, two hours. Repeat step five for objects in the second jar.

Results: What happened? Describe everything. You don’t need to include explanations of why something occurred. Make sure to bring to jars to the science fair!

Easy Kids Science Fair Project Idea and Demonstration

In this science project you will learn how to create a thermometer to measure heat.

This is an instrument used in various applications to measure temperature. Doctors use them to check our body heat and we use a gauge outside to see how cold or warm the weather is. In the United States we general use Fahrenheit to measure the temperature but you can also use Celsius. With Fahrenheit 32 degrees is freezing and 0 degrees is freezing with Celsius measurements.

Here is what you will need to get:

Water Alcohol (rubbing alcohol – DO NOT DRINK) Clear plastic bottle. Use a common water bottle which is empty Food color Straw Play dough

Instructions to make this equipment:

Mix equal parts of the water and alcohol together to make about ¼ cup. This means you will need 1/8 cup of water and 1/8 cup of alcohol. Do not make more than this amount. Pour the liquid into the plastic bottle. Put a few drops of food coloring into the bottle. This will be your measure for the thermometer so make it interesting. A normal gauge uses red as its color because it stands out so if you want it to look traditional use a red food color. Mix the color with the liquid until blended. Insert the straw through the opening but do not let it touch the bottom of the bottle. The bottom of the straw should sit in the liquid but not touch the bottom. Use the play dough or clay and put it around the mouth of the bottle securing the straw in place. You can actually wrap the dough around the lip a little to make sure it seals the bottle and holds the straw where it should be. DO NOT DRINK THIS!

Now warm your hands up by rubbing them together quickly and then place them around the bottle. Hold them on the bottle and watch the straw in your thermometer rise.

Congratulations! You just made a thermometer and it is showing the heat created by holding your hands on the bottle.With a thermometer when the solution inside gets warm it expands and pushes the mixture up the opening because it no longer fits in the bottom of your plastic container. If your mixture would get very hot the alcohol would end up spilling out the stop of the straw.

Leave your thermometer on a counter and watch it through the day and over a week time period to graph how it changes. Does it go up if the bottle is placed in the sun? What happens when it is shaded? Now this won’t show the exact temperature outside but it does show change in warmth and coolness by the expansion of the mixture.

When finished with your product. Make sure to have your parents dispose of the material in a proper place and you will have to throw away the bottle. It cannot be used for anything else. Enjoy this science project. You could demonstrate this at a fair by having a light to place the bottle by and a bucket with ice.

If you are looking for an easy science fair project you really don’t have to look far. There are ideas all around us. Pick any topic that interests you and you can come up with a science fair project for it. Remember, your project doesn’t have to be complex to be good. You can pick an easy science fair project and as long as you understand the project, are able to explain it and present it nicely, you will get great marks. You may even get marks better than some of your peers who choose to do complicated projects that they don’t fully understand.

Easy science fair ideas are testing people’s sense of smell. This can be accomplished by gathering a few different scents and asking some volunteers if they can identify them. Another easy project would be to see if the surface on which a snail is travelling affects the speed that it moves, you could investigate whether cockroaches have a sense of direction, or if ants prefer plain water, sugar water or salt water.

You could also test and see if plants will grow towards light, or if they can grow without sunlight at all. If that doesn’t interest you, you could try making your own tornado. This is a surprisingly easy experiment; all you need is water, a jar, some dish detergent and food coloring. Mix the water, a teaspoon of dish detergent and some food coloring into a jar, shake it up for 20 seconds and then give it a spin. You will then have an instant tornado! There are endless possibilities so let your mind go wild and you are sure to come up with a great winning project!

Easy Science Projects For Kids – Science Made Simple and Fun

admin — Thu, 05 Nov 2009 04:24:44 +0000

Easy science projects for kids can be found anywhere, even in your own house or backyard! There are many fun and easy projects kids can do, such as testing to see what flavor of water ants will prefer, like plain water, lemon water or sugar water. Other projects can focus on racing snails, or seeing if cockroaches have a sense of direction.

Another easy project involves learning how plants grow. All you need is paper cups, dirt, water and some seeds. Fill a few cups with soil and plant some seeds in each one. Place one in a sunny spot such as a windowsill, place another in a shady spot such as in your living room, perhaps on a shelf, and place one in a closet. Water them all regularly and let your child see which one grows best. A similar project is to show your child how plants absorb water. Simply get a few paper cups and fill them with water, add a different food coloring to each cup and place a white carnation in each one. The next day, let you child observe the flowers. By then, they should have changed color to match the food coloring you put in.

You could also show your child how sound is caused by vibration. To do this you need a few small drinking glasses, a spoon and some water. Fill each glass with a different amount of water and have your child tap each glass with the spoon and observe how each glass makes a different sound, depending on how much water is in the cup.
