Awesome Aquifers

Objective
To create a working model aquifer, learn about groundwater, increasing one’s understanding of groundwater and related concepts.

Duration
60 minutes

Age Range
5th grade through adult

Materials
Save time and get all the supplies you need by purchasing the Awesome Aquifer Advanced Hydrology Kit from our online catalog, or see the following list of suggested materials that can also be used to build your model aquifer. Think creatively, you may discover additional materials to include or discover other ways to use materials than what is suggested below. 

• A transparent container: to build the aquifer in. This could be a jar, 2-liter soda bottle, small aquarium, display box, plastic storage container, etc.
• Sand, gravel, soil, modeling clay/plumbers putty, sponges: represent geological strata
• Plastic syringe or lotion pump: used as a well (pumping or injection)
• Aquarium airline tubing: can be used as part of a well
• Nylon netting, hosiery, coffee filter, or window screen: works as a well screen
• Rubber bands, plumber’s putty, or electrical tape: used in various ways to hold parts together (e.g. well screen) Spray bottle: used to demonstrate rain
• Liquid food coloring and/or powered drink mix: represents contamination
• Film canister: can be used as an underground storage tank

Procedure
Students will need some initial groundwater knowledge prior to this activity. This activity is best when students have already been introduced to groundwater and related concepts. Discuss the concepts included in list provided and discuss related topics such as possible sources of groundwater contamination and possible prevention or reduction methods.  Divide your class into teams of 2-3 students (each team will need enough supplies to construct their own model). Distribute copies of the Awesome Aquifer Concept list to the students as a guide for their construction and presentation.

Activity Steps

1. Design and build a working model aquifer (allow 30-45 minutes).
2. Allow the students time to discuss in their team how they will construct their model. Give the students ample time to construct a working aquifer with materials such as those listed above and maker sure they have had time to prepare a short presentation with their model.
3. Each team of students will present their model to the other teams, demonstrating and explaining concepts included in their model (10 minutes per team, use a timer.)
4. After each team of students has completed its demonstration have students discuss what they learned.
5. Discuss real world situations (drought, contamination…) that may affect groundwater supplies and discuss how communities and individuals might deal with these situations.

Variation
Allow the students to compete to see which team can create the best model. Use the concept list as a score sheet (below) and give students points for each concept they cover. Total points to see which team scored the highest.
