After some research, I guessed that the lower the p H the more copper would be deposited on the nail.
For my experiment, I made several different solutions of acid with p H’s ranging from 1 to 7. After that, I took out the penny and replaced it with the nail in each jar and observed what happened over three days.
Try testing different size melons and different height drops. Source: Teeter-Totter The goal of this project is to create a compound machine using pulleys and levers that would be able to lift a Barbie doll up and down by pulling a string by the player.
A common problem on the playground is that you sometimes can’t find another person to go on the teeter totter with you. Source: and Test a Paper Bridge This project helps you discover how to create a strong bridge using just paper.
These experiments will help the scientist to determine if people have a dominant hand, foot, eye or ear. Kids will get to explore the relationship between oil and water in terms of density as well as hydrophilic/hydrophobic compounds. Source: goal of the project is to find out how different lighting conditions affect seeds germination and growth.
This article will give you the step by step procedure for this project. Source: Steve Spangler A Petri dish prepared with nutrient agar (a seaweed derivative with beef nutrients) is an ideal food source for the bacteria you’ll be growing.
Once you finish, you'll have a well-crafted, 250-words-or-less summary of your science fair project.
To begin the process of writing an abstract for your science fair, you need to answer several questions about your project.
Here are the five key questions: At this point, your answers need to include all the pertinent information, but still be as brief as possible.
Now that you have answered the above questions, you need to write the first draft of your abstract.
