In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

Many people get water from a source deep underground, called groundwater.

In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.
