Step 5: Hypothesis A hypothesis is your guess about the answer to the project question. This is not a “wild” guess. You need to have a good reason for the hypothesis you state. Example: Project Question 1. If two solution, glue and borax, are mixed, what effect would the viscosity of the glue used have […]

Sonoran Desert: Saguaro
The Sonoran Desert is in southwestern Arizona, southeastern California, most of Baja California and the western half of the state of Sonora, Mexico. The Sonoran Desert covers about 100,000 square miles (260,000 sq km). The Sonoran Desert is rich in plant life with at least 2,000 different species. But two types of plants th distinguish […]
Engineering:Solar Power
Garrett Yazzie: A navajo indian junior high student not only entered but won first place in the 2005 annual Arizona American Indian Science And Engineering Fair. Garrett’s has been called the “junk yard genius” by some because he secured most and maybe all of the parts for his solar heating project from a junk yard. […]
Science Project: Slime/Data
Step 8: Data For this Slime experiment, you will be recording the distance that each test sample of slime flows in a specific amount of time. You should test four or more slime samples from each Glue Viscosity. Determine the best way for your to record your data. For example, a sample data chart is […]
Science Project: Slime/Experiment
This page is a continuation of directions for making slime as a science fair project. Note: This information contains ideas and information. It is not intended to be used directly for your project. Instead, use the information as a guide for designing and developing your own science fair project. Step 6 : Example Experiment The […]
Science Project:Slime
How to Develop a Borax Slime Science Project Step 1. Topic You have your topic, which is: Making Slime Step 2. Research Research is learning about your topic. A good way to learn about slime is do an exploratory investigation about making slime. Exploratory Investigations: These are generally simple experiments performed for the specific purpose […]
Dilatant: Slime
Slime is a cross-linked polymer. A polymer is made of large molecules made of repeating units called monomers. A cross-linked polymer means that there are links connecting the molecules, much like the rungs in a ladder. The ladder diagram is similar to a cross-linked polymer only in the parts making it. The cross-linked polymer molecules […]
Moonshine
Q: Why is the Moon brighter at night than during the day? A: The Moon is more visible at night because the sky is darker. During the day there are stars in the sky but they are not visible because the Sun’s light makes the sky so bright. Notice how bright the stars look at […]
Polymer: Slime Facts
Elmers glue and other comparable school glues are polyvinyl adhesive (PVA). Slime is made by mixing PVA glue with a solution of borax. Slime is a polymer, which is a chemical consisting of large molecules made of a linked series of repeating units called monomers. The polymer slime produced is not as runny as the PVA glue […]
Polymer:Translucent Slime
Homemade Slime Recipe 1. In a small jar, make a Glue Solution by mixing 4-ounces (1/2 cup) of Elmer’s Glue Gel with 1/2 cup of tap water. Mix thoroughly. 2. In a second small jar, make a Borax Solution by mixing 1 teaspoon of Borax powder with 1 cup of tap water. Mix thoroughly. 3. […]
