It's Time for Science Fair Projects!!!


Attention Parent(s)/ Guardian(s) and Students,

        During the next two weeks, your fifth grade student will create a Science Fair Project to enter into the contest here at school.  I have taken the time to provide you and your child several links to look at in order to help create a great project.  These links include information about choosing the right project, a step by step project guide, and useful information on how to prefect the project.

       As you know, throughout the year, I have strongly expressed how important i think reading and writing skills are in all content areas.  For this project, your student will also be required to compose a two page essay.  A link is provided to help with the format.

     Note: It is important to remember what a hypothesis is.  As a reminder, I have provided the definition: Hypothesis

        It is time to get started. I hope you take the time to sit down with your student and look at the links provided.  The last link will be a helpful tool when you have finished your project.  It provides helpful information from choosing a topic to standing and delivering the project.  


         As always, thank you for your support in helping your child better his or her education. 
Together we can achieve goals!

Experiment Four:


Color Exploding Molecules




Project Subject to Fourth Grade Science:
Tennessee State Standards:

GLE 0407.Inq.1 Explore different scientific phenomena by asking questions, making logical

predictions, planning investigations, and recording data.

GLE 0407.Inq.3 Organize data into appropriate tables, graphs, drawings, or diagrams.

GLE 0407.9.2 Explore different types of physical changes in matter.

Introduction and Purpose:

It's an explosion of color! Some very unusual things happen when you mix a little milk, food coloring, and a drop of liquid soap. Use this experiment to amaze your friends and uncover the scientific secrets of soap (stevespanglerscience.com). The purpose of this science project is to cover topics such as mixtures, molecules, and the results of bipolar characteristics in dish soap. This topic also covers changes in physical properties.

Hypotheses:

In this project, three questions require answers: What will happen when food coloring is dropped in water? The hypothesis for this question is when food coloring is dropped in water, the food coloring will combine with the water without even stirring the mixture. The second question is what will happen when food coloring is dropped in cooking oil? The hypothesis for this question is when food coloring is dropped in oil, the food coloring will sink to the bottom, resulting with no mixture. The final question is which type of milk will result in more color explosion: whole milk, skim milk, or half and half. The hypothesis for this question is whole milk will result in more color explosion.
