Beneficial vs. Harmful
Science Scenarios
100

This is an area of land where all the water that falls in it drains off into a common outlet like a creek or river.

What is a Watershed?

100
  • This "hidden" water is found underground in the cracks and spaces in soil, sand, and rock.

What is Groundwater?

100

 Humans rely on the ocean for resources like food, climate control, and this gas produced by plants.

What is Oxygen?

100

This structure is built by humans (like sinking an old ship) to create new homes for sea life.

What is an Artificial Reef?

100

If a city paves over its entire Recharge Zone with solid concrete, what happens to the Aquifer?

It cannot refill (it dries up).

200

This term describes water from rain or snow that flows over the land surface rather than soaking into the ground.

What is Runoff?

200

An underground layer of rock or sediment that holds and moves large amounts of groundwater.

 What is an Aquifer?

200

These microscopic organisms in the ocean produce over 50% of the Earth's oxygen.

What is Phytoplankton?

200

 Dumping motor oil into this street structure is harmful because it leads directly to the watershed without being cleaned.

What is a Storm Drain?

200

Name one way a coastal cleanup helps the ocean system.

Prevents plastic/trash from harming animals (turtles/birds).

300

 Any body of water found on top of the Earth’s surface, such as rivers, lakes, and streams.

What is Surface Water?

300

The "line" or upper level of the underground zone where the soil is completely soaked with water.

 What is the Water Table?

300

Catching fish faster than they can reproduce is a harmful activity known as this.

What is Overfishing?

300

This beneficial city garden is designed with native plants to catch and filter runoff naturally.

What is a Rain Garden?

300

This human-made hole is used to pump groundwater up to the surface for drinking or farming.

What is a Well?

400

When fertilizers from farms wash into a pond, it causes this "green" problem that takes oxygen away from fish.

What is an Algae Bloom?

400

The specific land area where water can soak into the ground to refill an aquifer.

What is the Recharge Zone?

400

This term describes how humans rely on the ocean for survival.

What is Dependence?

400

These accidental releases from shipping tankers destroy marine habitats and kill birds.

What are Oil Spills?

400

This is the artificial application of water to land to help crops grow for food.

What is Irrigation?

500

Humans build these facilities to remove harmful pollutants from "dirty" water before sending it back to rivers.

What is a Water Treatment Plant?

500

Taking water out of a well faster than it can refill can cause the ground to do this.

What is sink (subsidence)?

500

Burning fossil fuels increases ocean temperatures, which leads to a higher rate of this part of the water cycle.

What is Evaporation?

500

This beneficial construction uses porous bricks to allow rain to soak into the soil instead of running off.

What is Permeable Paving?

500

Setting aside a "No Fishing" zone is a beneficial act that protects this oxygen-producing organism.

What is Phytoplankton (or the marine food chain)?
