Ash Affects on Plant Life
The first project is a simulated study of the affect of volcanic ash on plant life. You will need four small, potted plants of the same species. Three of the plants will be treated with the addition of ash (charcoal ash or wood ash from a fireplace will work for this). One plant will have a few tablespoons of ash sprinkled onto the potting soil, another will have 1/2 cup of ash and the third will receive a full cup of ash. The ash should be layered on top of the soil (as if it has fallen from the sky) and not mixed in. The fourth plant receives no ash. The plants should be watered and fed equally. You want to study the affect of the ash as each plant grows. Does the ash hurt or help the plant?
Volcanic Rocks Project
A second approach to a volcano-related science project is to focus on volcanic rocks. Obtain a sample of three volcanic stones - pumice stone, obsidian, and rhyolite. Compare and contrast the characteristics of the three stones, including density, hardness, weight and how they are formed. Then, demonstrate the qualities to your class by dropping the rocks into a clear tub of water (the pumice should float), weighing each rock and bringing in examples of products that use volcanic rocks (like Lava soap which has pumice in it). Samples of these stones can be purchased at certain museum gift shops.
Volcanic Eruptions and Weather
Another thought-provoking project that you could do on volcanoes involves researching how volcanic eruptions affect the climate and weather patterns. This is primarily a research project so you will need a computer and a library card. Research a volcanic event in recent history (nothing before 1950) - Mt. St. Helen's eruption is a good choice. Find as much information as you can about the weather patterns that occurred after the eruption. You want to find information on temperatures, changes in precipitation and seasonal affects. Then, research how volcanic eruptions can affect weather pattern. Observe and report any correlation you find between your weather research and the information on volcanoes and weather.
Model Volcano
The final project is the tried-and-true baking soda volcano. You will need a soda bottle. You can use whatever size bottle you want, but the larger the bottle, the larger the volcano. Cover all parts of the bottle except for the opening with clay dough and form your volcano. Use a funnel to pour 1/4 cup of warm water and 2 tablespoons of baking soda into the opening of the bottle (use more baking soda if you want a bigger reaction). Add five drops of food coloring and dish detergent. Then pour 2 tablespoons of white vinegar into the bottle and watch the fizzing eruption.
