Straining Out the Dirt
Learners take on the role of environmental engineers as they design water filters.
How Plants Grow
Source Institutions
In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.
What Molecules Make the Holes in Bread?
Source Institutions
In this activity, learners will discover why there are holes in bread.
What Does Life Need to Live?
Source Institutions
In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
Science at the Waterpark!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.
Can Nutrients in Water Cause Harm?
Source Institutions
In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.
Breaking the Tension: Surface Tension 1
Source Institutions
Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.
Moving On Up: Capillary Action 1
Source Institutions
Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.
Runaway Runoff
Source Institutions
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.
Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.
Dip Dip, Hooray
Source Institutions
Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.
Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.
Clear Water, Murky Water
Source Institutions
How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?
Global Climate Change and Sea Level Rise
Source Institutions
In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
