Explore Lemon Tree (James) Circumference Average: (15 + 14.5 + 14.7)/3 = 14.73 inches Diameter: 14.73/pi = 4.7 inches Height: 112 inches Benefits: Storm Water: $0.24 | Electricity: $1.85 | Air Quality: $5.62 | Property Value: $30.58 | Natural Gas: $0.06 | CO2: $0.35 Shamel Ash Tree (James) Circumference Average: (74 + 73 + 73.6) / 3 = 73.5 inches Diameter: 73.5/pi = 23.4 inches Height: 949 inches Benefits: Storm Water: $2.15 | Electricity: $14.98 | Air Quality: $43.60 | Property Value: $275.18 | Natural Gas: $0.87 | CO2: $9.07 Lemon Tree (Matthew) Circumference: 35.5 inches Diameter: 35.5/pi = 11.3 inches Height: 169 inches Benefits: Storm Water: $6.30 | Electricity: $14.40 | Air Quality: $4.58 | Property Value: $74.31 | Natural Gas: $0.19 | CO2: $0.41 Lime Tree (Matthew) Circumference: 31.0 inches Diameter: 31.0/pi = 9.9 inches Height: 92.3 inches Benefits: Storm Water: $2.53 | Electricity: $21.50 | Air Quality: $4.68 | Property Value: $82.80 | Natural Gas: $0.30 | CO2: $0.30 Swamp Mahogany Tree (Patrick) Circumference: 51.5 in. Diameter: 51.5/pi = 16.4 in. Height:555 in. Benefits: Storm Water: $9.90 | Electricity: $20.47 | Air Quality: $5.87 | Property Value: $61.19 | Natural Gas: $0.21 | CO2: $1.05 Queen Palm Tree (Kai) Circumference: 36.5 in. Diameter: 36.5/pi = 11.6 in. Height: 486 in. Benefits: Storm Water: $1.07 | Electricity: $2.98 | Air Quality: $0.87 | Property Value: $27.10 | Natural Gas: $0 | CO2: $0.11 Trends: -Property value for all trees were the highest in benefit value while natural gas was the lowest - Two trees were damaged by human. Research Ideas: 1. How do animals effect trees? 2. What benefits make a tree good? 3. How do animals determine what makes a tree a good habitat?
Research Question How do insects (ants) affect the leaf health, trunk health, and physical appearances? This question came up in a discussion overall about tree health. This question relates to trees and their way of life.
Predictions There are two main outcomes. One, the insects infesting the tree would harm and even may kill the tree. This could happen since we've seen that insects damaged the leaves of trees near our neighborhood. Another outcome could be the insect protecting or helping the tree. This outcome seems to more unlikely and only a few insects actually help trees.
Experimental Design Experimental Design Questions (Separate from the rest of the Experimental Design, which will be uploaded later and be updated here later as well) ... What is our plan? Our plan is to research and observe the effects of ant habitation towards the health of trees. Be sure to include enough detail that another group can replicate our experiment. What variables will we test? Amount of ants, tree diameter, tree appearance, such as color, and the amount of indicators of bad tree health, such as cankers and sprouts. What variables will we keep constant? The variables that should be kept constant are time of day we record the data, and the temperature of day should be relatively consistent. Also the average amount of ants should be constant. How will we record our data? Use senses, like sight and touch, as well as other tools from the materials list. .... (Actual Transcript of our Experimental Design Rough Draft) ---- Abstract n/a Purpose Observing the relationship between ants and tree health. Hypothesis As ants are introduced into the environment, they will harm the tree's health, and where there are no ants, the health of the tree is preserved and not negatively influenced. Materials Measuring tape/ ruler and string Calculator Trees Ants (in general) Magnifying Glass Camera Gloves Marker Cutting Tool (Optional) Ant bait (Sugar Water Solution) Tap Water Regular/Granulated Sugar Spray Bottle Procedure Sugar Water Solution Get tap water and regular sugar, as well as a container to mix the solution in and a spray bottle to pour the final product of the solution into. Prepare and measure a 25% sugar-water solution in 30 oz of water. Calculation: 30 oz Water * (25 oz Sugar/ 100 oz Water) = 7.5 oz Sugar BTV 30 oz of Water Transfer the solution into a spray bottle so it’s ready for action. Tree Observations Find 6 similar trees, making an experimental group containing 3 trees and a control group containing another 3 trees. Mark those trees “Experimental” and “Control” respectively. Record the presence of ants on the tree. For all trees, collect information from the diameter of the tree, the color of the leaves, any signs of tree diseases (Sprouts, Cankers, ect.), and stem’s overall physical appearance for a baseline. In the experimental group, use the spray bottle filled with sugar water and spray sections of the tree that are higher up. Meaning, the leaves, the main stem of the tree, and 2-3 branches. Repeat steps 3 and 4 every day, for one week.
