Science Project Idea for 4th Grade Student

admin — Thu, 13 May 2010 01:13:40 +0000

Here is a science project idea. Children in elementary school such as 4th through 6th grades would be able to do this as well as middles school 7th and 8th grade students. In this science project you will determine which substance has the most acid in it to clean tarnish off of coins.

Items you will need for the project:

8 cups 8 tarnished copper pennies Tomato juice Lemon juice Vinegar Window cleaner A household cleaner like simple green or fantastic Ammonia Toothpaste Baking soda Paper towels Graph paper

For this experiment you will determine from the constant, the tarnished copper penny, which of the liquids or materials removes tarnish the best.

Line up your glasses in a row on a counter top. Make sure you will not be using this space for something else. The best time to do this is in the evening so that you can let the pennies soak overnight.

Fill each cup with one of the ingredients. You should now have 8 cups with a different substance in each. You do not need more than about 1/8 cup of each ingredient. Just use enough for the penny to be submerged under the liquid. For the toothpaste squeeze a little out into the bottom of the cup and place the penny on the paste and then squeeze more on top of the coin.

For the baking soda mix a slight amount of water with the soda to form a paste and do the same as with the toothpaste making sure the bottom and top of the penny is covered with the substance.

Let these glasses of liquid sit overnight at room temperature.

In the morning place a paper towel in front of each cup. Remove each penny from the liquid it has been sitting in and gently rub and wipe the outside of the penny. Use a different paper towel for each coin.

After you are finished with all eight make a visual observation. What does each penny look like? Also look at the paper towel to determine which one has the most tarnish on the paper. Using your graph paper record each substance and make a bar graph showing how much tarnish each one removed.

When you started you should have made a hypothesis about which substance would remove tarnish the best and why it would remove the tarnish effectively. Was your theory correct?

This science project is great for middle school or high school. It can even be done by a younger student in 3rd or 4th grade. Make sure to have your parent help with the chemicals by pouring them into the glasses and disposing of them. You may want to wear gloves with the various chemicals.

School Science Projects – What Teachers Really Want

Looking for a project that can get your teacher’s attention? You need not look any further! And yes, while you’re on the lookout for the best possible project, don’t forget to hop into our library for free guidelines on your projects.

How to Make Your Project Grab Your Teacher’s Attention? To get you started, here are some things that teachers are looking for in good Science projects.

STEP #1: Choose a topic that interests you. Teachers are looking out for science projects that are wholeheartedly done. They can tell a project done well and just for the sake of doing it. It is therefore important to choose a topic that you love.

Your ideas about the following things could turn into science projects:

1. Things That Amaze You: Ever wondered how a huge airplane manages to fly in thin air? Grab some books on that topic from your library, and do some research. There are many like you who are equally confused. Maybe you could look for books on gravity and aerodynamics.

2. Things That You Encounter Daily: Ever wondered how your camera works? Try constructing a pin-hole camera. Or how your car works? Experiment with various home-made models.

3. Things That Others Say: Find out why your parents tell you to exercise or eat your vegetables or go to bed early. Research and learn the positive benefits of these habits on your body. Why do people prefer a particular brand of toothpaste? Is there really a difference? This could give you a practical topic for your project.

If you’re looking for ideas, check out this guide to good Science projects.

STEP #2: Just Do It! Teachers try to determine how much personal effort a student puts in, in order to create the project. Here are a few steps that can enhance your efforts:

1. Collect Facts from Real Life: Look around your home, your neighborhood and the World Wide Web for facts and materials that support your project.
2. Collect Facts from Science: Use science to go about your project.

Ask yourself the following questions:

* Which scientific principle am I trying to demonstrate?
* If I change one parameter how will it affect another?
* If I do things differently how would it affect the result?

3. Collect Facts From Your Own Experiments: Perform a set of actions and write down the results. Let the results be available for your teachers to study.

STEP #3: Make It Presentable Well presented science projects make the first impression on teachers. Make your project simple and clear.

Here are a few ways to make your project presentable:

1. Present Information Clearly: Get rid of all ambiguity by presenting the facts and figures in a neat tabular and graphic form.

2. Present It Using Pictures: Since our minds understand pictures better, a picturesque presentation would make your project entertaining and knowledgeable.

3. Present an account of your experience: Write an account of how you went about creating your project, what hindrances you encountered and how you arrived at the final step.

And yes, there is one thing you could do to boost your confidence. A day before the science fair, run a mock presentation. Have someone ask you some questions and try to answer them. Imagine the judge and your teachers examining and appreciating your project. For more resources on picking a great topic and creating a great project with minimal stress, check out the links below.

Good luck!
