Science Fair Projects  

The Science Fair is on TBD (To Be Determined)  

*SCIENCE FAIR PROJECTS NEED TO BE COMPLETED BY TBD*

 Use the scientific method.  

1. Exhibit --> either a display board or a powerpoint presentation  (1/3)

2. Oral Presentation to the class (1/3)

3. Research Paper - 1 page typed or 2 pages handwritten, ~200-250 words.  

 Here are some helpful websites:

Very Important Tips/Tricks/Hints

1. Your visual Exhibit should NOT contain your written Research Paper.

2. What is your Independent Variable?  Dependent Variable?  Constants?

What does your report need?

• Name and Class

• Project Title

• Body Paragraphs  

1)      Introduction

 In this section, explain your problem or question.  Why did you choose this problem?  Where did you get the idea?  Give any relevant background information here as well.  (Why did you do this project?)

2)       Hypothesis

 In this section, state your hypothesis.  Why did you make this hypothesis?  What observations did you make that led you to this hypothesis? (Remember: Your hypothesis is “a best guess based upon your observations.”)

3)      Materials and Methods

 In this section, please give a list of your materials. You may simply

list your materials in a “bulleted list.”

4)       Results

 In this section, explain what happened in your experiment. Use charts, graphs, data tables, etc.

5)      Conclusion

 What did you learn?  Was your hypothesis right or wrong?  What could

you do next with this experiment?  Is there another experiment

that could follow this one?”

Lab #9 - Calculating Density of solids (regular- and irregular-shaped)

Lab #9 - Calculating Density of solids (regular- and irregular-shaped)

All matter has mass and volume.  Mass is a measure of the amount of matter an object has; its units are given in grams (g) or kilograms (kg).  Volume is the amount of space an object occupies; the units for volume liters (l), meters cubed (m³), and gallons (gal).

If we know the mass and volume of an object, then we can use the following equation to calculate its density: D=m/V   Density = mass/Volume

     

The symbol M stands for the mass of the object, and V the volume.  Density has the units of mass divided by volume such as grams per centimeters cubed (g/cm³) or grams per milliliter (g/ml).

Problem

Will a larger object always have a larger density than a smaller one?

Hypothesis

Materials

Triple beam balance

Ruler

Two different sized cubes

Two irregular-shaped objects

Procedure for a regular-shaped object

1. Measure the mass of your objects using the triple beam balance.  Record your measurements in the data table. 
2.  Use a ruler to measure the dimensions of your rectangular objects; measure to the nearest tenth (0.1) cm.

Calculate the volume in cm³ of your spherical object by measuring its radius.  Use the following equation to calculate its Volume: Volume of a Sphere = 4/3 π r³

3. Record your measurements in the data table. 

Results for a regular-shaped spherical object

	Mass (g)	Volume (cm3)	Density (g/cm3)
Object 1(marble)
Object 2 (styrofoam sphere)

Radius of marble = ___cm

Radius of Styrofoam sphere = ___  cm

Volume of a Sphere = 4/3 π r³

D=m/V

 (4/3)(3.14)(r)(r)(r)

Analysis for a regular-shaped object

1. Which object had the greater density? 

2. A block of wood has a mass of 8 g and occupies a volume of 10 cm³.  What is its density?

Conclusion

(Write a summary of your experiment.  Was your hypothesis right?  What did you learn?  What could you do next time?  Was it fun?  How is this related to what we are learning in class?)
