1. Dress appropriately. Due to the harsh environment conditions, there are safety hazards that can be risky and life threatening. Such things include ticks, poison ivy, and other insects (boots are handy in swampy areas).

2. Before heading outside to your work area, plan ahead with materials and things to do. That way, when you're outside, there are no mishaps and wasted time.

3. Work together to split up work and to put heads together. This will help when there is limited amount of time and will be more efficient for the final conclusion.

4. Always wear goggles and gloves when chemical testing. Chemicals can be extremely hazardous and cause severe burns and toxicities. Make sure to know where emergency showers, eye washes, and fire blankets are located in the science room.

5. Keep materials clean when experimenting. There are always ways to contaminate solutions so be careful with tools you are using.



1. To make sure data is accurate, you may use more than one transact other than your three sites to come up with more data. This will help clarify the answer to your problem.

2. When collecting soil samples for manganese and ferric iron testing, it is helpful to use a soil core sampler to retrieve about 15 cm worth of dirt. That way, there will be enough dirt for all testing.

3. Collect soil samples and record data with the densiometer around the same time of day for each trial. Plant growth can differ throughout the day.

4. When collecting percentages through the densiometer, make sure to collect data throughout the transact and not in a clustered area. Also, keep the metal weight in the center of the grid.
