Delta formation

A delta is a landform, it is an area that looks like the Greek letter "delta"   (look at the picture), also it looks like a triangle. This area forms at the rivers' mouth, just where they meet the ocean. Erosion and deposition play an important role in "deltas" formation. Erosion moves the weathered materials (pieces of rock, sand, sediments, etc.) along the river, as it flows to the ocean. All these materials are deposited at the river's mouth forming this triangle or "delta". If you look at a delta from a plane, it will look similar to the roots of a plant. Here are some pictures which will give you an idea of what a delta is:

Here are a couple of videos which show how the Nile River's delta in Egypt and the Mississipi River's delta in The United States formed and how they look. Watch them, I think you will get a better idea about what a "delta" is:

MORE INFORMATION FOR YOUR SCIENCE PROJECTS

Here is some more information so you can complete the investigation process of your Science projects. Look at the topics and check the links.
States of matter: Liquid, gas and solid. This links includes games and activities as well as videos to help you understand better all about this physical property of matter:

Some Science games and activities

The way in which energy works is applied in a lot of different ways, for example the roller coaster, have you ever ridden on one? Here are some games to experiment with kinetic and potential energy to design a thrilling roller coaster ride, do you want to try?

Enjoy the ride!!
 

Some tips for your Science project investigation.

For those having problems to find information for the Science Fair Project investigation part, I would like to recommend some good sources of information that I have found.
 Remember your investigation is what supports your hypothesis so it is very important that you take time to read carefully and understand what you read. 

1. Take notes of the most important things and of the facts that will help you explain your results at the end of the experiment. 
2. You need to check at least three different sources (books, magazines, web pages,etc.) 
3. When you check a book, you need to include the book's title, author, editor and the pages that you consulted. 
4. If it is a magazine, you need to include the magazine's name, volume, year and the title and author of the article you read. 
5. Finally, if it was a web page, you need to include the internet address where you got your information and the page's name. If the name of the author is mentioned, also include it.

The most important thing is that you learn something new about your project and that you can apply this information to your experiment so you can explain your results better.

Don't forget that your experiment must include:
1. A clear question with a measurable answer. It means that you should be able to measure your results in some way: distance, time, capacity, weight, size, etc.
2. Investigation that helps you answer the question and helps you support a hypothesis.
3. A hypothesis showing a cause-effect relationship.
4. Variables - things that you will change in your experiment.
5. Constants - things that will not change: example: same amount of water, same amount of light, same type of seeds, etc. 
6. List of materials.
7. Steps to follow.
8. Chart or table to record your observations.
9. Analysis of the data you recorded during your observations.
10. Conclusion, based on your results and investigation. Explain if your hypothesis was correct or not and why.
