4. Water Experiment
Step 1 ~Measure out 50 milliliters of water into a beaker A from the water container.

5. Water Experiment
Step 2 ~ Grab a funnel and put a single coffee filter in it. After this fill the funnel with sand up until the marked line that you will find on your funnel.

6. Water Experiment
Step 3 ~ Place the funnel with the filter paper and sand on top of beaker B.

7. Water Experiment
Step 4 ~ Pour the 50 milliliters of water from beaker A into the funnel and watch it drip down into beaker B. Make sure that you do not fill the funnel too high with water, make sure the water level does not go above the sand.

8. Water Experiment
Step 5~ After beaker A has been emptied, wait for the water to finish filtering through the sand ( about 30 seconds). After this measure the amount of water that is in beaker B by looking at it while level with the water level.
Sand

9. Water Experiment
Step 6~ Compare that amount of water that is in beaker B to the amount that you started with in beaker A (50 milliliters). Also note the color change in the water from beaker A to beaker B’s color. Did the color change?

13. Water Table
Water Table is were the water is underground.

14. Groundwater Flow
Groundwater flow is the direction the water moves underground.

15. Evaporation
Evaporation is when water becomes a gas and rises into the atmosphere.

16. Precipitation
Precipitation is when some form of water falls to the ground under gravity. Examples of precipitation are snow, rain, hail, and freezing rain.

17. Well
A well is an opening in the ground. This hole goes down deep enough until it hits the water table. Water then can be pumped up from the water down at the bottom of the well ( or pulled up with a bucket and some rope).

18. Cone of Depression
A cone of depression is the dip in the water level of the aquifer in the spot where the well is dug.

19. Porosity Porosity~ Amount of empty space between objects.
Low Porosity~ When small rocks are very close together. There is little space between the rocks for water.
High Porosity~ When larger rocks are together they create large gaps in between the rocks. This allows water to go through quickly.

20. Aquitard
This is an area of rocks which water cannot, or has a hard time, passing through.
It has low Porosity.

21. Aquifer
This is an area of rock that water travels through very easily. It has high porosity.

22. Acid Rain
Acid Rain is a mixture of gases and water that contain a high amount of acid which causes the rain to have a lower pH than normal. Normal rain has a pH around 5.6 acid rain has a pH around 4.3.

23. Runoff
Runoff occurs when the ground can no longer take in more water. The excess water s flows on top of the ground toward oceans in the form of steams, rivers , and lakes.

24. Plants
Plants take up water from the ground and they thing in that water goes into the plants. Thing such as oil and pesticides can end up in the plants.

25. Pesticides
Household
Farm

26. Household Pesticides
Household pesticides include insect killer, fertilizer, and weed killers. They get into the ground water and make it unsafe to drink.

27. Farm Pesticides
Farm pesticides are powerful chemicals sprayed on crops to kill weeds and bugs. It is usually done with an airplane.

28. Nuclear Waste
It was disposed of at the bottom of the ocean and last thousands of years.

29. Industrial Waste
It is chemicals like lead, mercury, and acid that are dumped into the water. They can be harmful to humans and other forms of life.

30. Household Waste
Products such as bleach and soaps that are poured down the drain. They can be poisonous if not purified.

31. Oil
Can come from cars, ships, oil refineries and gas stations. Oil is extremely toxic and hard to dispose of.
