Investigating Acid Rain: The Affect of Acid on Seed Germination

While no diagrams are required, it is always a good idea to photo document the process so you have great visuals for your science fair board!

This lab will take one class period for background information on acid rain, one class period to set up the lab, several pieces of class for data collection, and then one class period for analysis and conclusions.

To take data On day three, open up your baggies and record the length of all of your seedlings in cm. Discuss what will be needed on a data table - Dates - Number of seeds germinated - Other observations?

If there is no growth, record the length as 0 cm. It was created using the following site.

How Does Acid Rain Affect Seed Germination?

Allow the students a few minutes at the beginning of the period each day for one week to collect and record data 8. We can explore one aspect of plant growth- germination and initial growth- fairly simply. Students will plan and conduct a controlled experiment to test a hypothesis about a relationship between two variables.

In three days, open the bags to take your first data! Acid rain is becoming more and more of a problem for our world. Air quality Resource Type: Any type of eyedroppers, or even straws, can be substituted for pipettes. The second solution should be approximately one pH level more than your initial solution.

How does acidity affect plant growth? Once all groups have shared all of their thoughts, discuss that maybe not all shared thoughts are accurate. Baking soda dissolve 4 tablespoons of baking soda into ml of distilled water This makes ml of solution lemon juice.

Lead into experimentation at this point. At the end, graph your data and draw a conclusion! You should also include a graph of growth averages over time- a line graph should do nicely.

When the protective coating is damaged, valuable moisture is lost. Set-up Count out 40 pinto beans, 40 ziploc bags, and 40 paper towels or napkins. At the beginning of the next day, allow the students to set up their experiments using the procedure they created the previous day 7.

On the final day, allow the students to collect their data and determine how they will present it to the class the following day This is different from what I have done in the past because I had everything set for them. The first day you open them, they are bound to be very small, if they have even sprouted at all- some may not.

Add either water or vinegar to get the pH to a whole number. For example, if you got the initial pH solution to 3, than this solution might be 4.

The Effect of Acid Rain on Seed Growth

Mix 3 parts distilled water with 1 part vinegar to make your first solution. Accuracy in mixing is not the most important part here- measuring the acidity is.

Acid rain also lowers the pH balance of soil, which affects the population of microorganisms that break down organic material. Terms, Concepts and Questions to Start Background Research Seed, seedling, pH, aciditiy, acid rain, commercial pollutants, air pollution, radicle, stem, cotylydon.

Ask each group to give one thought, and record on the board. Repeat steps to get a third solution.Effects of simulated acid rain on the pollen germination and pollen tube growth of apple (Malus sylvestris Miller cv.
