Triple beam balance Ruler Ra neater Beach water Proceed rest 1 . Get cedar, red oak, yellow pine and treated yellow pine 1/3 pieces of oft wood. 2. Retrieve 4 buckets. 3. Fill 2 buckets full of beach water and Fill 2 buckets full of rainwater. 4. Cut all the wood pieces into 6 inches. 5. Name 2 buckets treated for rainwater and for beach water. 6. Name 2 buckets for regular rainwater and beach water. 7. Place non treated wood pieces in both types of water buckets. 8. Place treated wood pieces in both types of water buckets. 9.

Retrieve a triple beam lance to measure weight of the wood when soaked in water. Record data 10. Repeat for non soaked wood. Record Data 11. Retrieve a ruler and measure the width of the wood when soaked in water. Record Data 12. Repeat for non soaked wood. Record Data Variables Types of wood Types of water As fete During my experiment I had to wear safety goggles while cutting the wood. Sources of Error During my experiment my wood was not all cut into same size pieces and the humidity outside had an effect on the rainwater as well as the coldness outside where I kept the buckets.

Application The way this could be applied to life is when building a tree house or anything, to see which wood would be durable if it was wet. Extension The way this project could be improved is by testing the durability when soaked in water by applying human force. Conclusion My hypothesis was that red oak would weigh the most and yellow pine appearance would change the most. My results did not support my hypothesis red oak was the second most change in weight yellow pine had the most change in weight, but red oak did have the most change in appearance.
