Motion in the Ocean
How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Ocean Acidification
If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

Water and Ice
Learners perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water instructional activity, students use their senses and inquiry tools to understand the changes in state of...
Curated OER
Rain, Rain, Go Away
Students conduct a number of experiments involving evaporation and condensation. They view and discuss a video about the water cycle and then design posters about the rain based on the book "Cloudy With A Chance of Meatballs".

Testing Your Water
Students perform several water quality tests on groundwater from their area. They use test strips to determine the pH, hardness, alkalinity, nitrates, iron and chloride levels.
Science 4 Inquiry
States and Phases of Matter
Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.
Curated OER
Rock Cycles, Crayon Cycles
Students examine the rock cycle and the path that rocks go through to rearranged in different ways. They define key vocabulary terms, then in small groups conduct a variety of experiments using crayon shavings as simulated rocks and...

The Watershed Quest
Learners examine their connection to local watersheds. They describe the water cycle and list species living in their local watershed. They also draw a map of their community.
Curated OER
Rainforest Deforestation and the Water Cycle
Students create terrariums (mini rainforests). They observe and discuss the life processes that occur in their terrariums and how changes in these processes affect the plants and organisms inside. They collect and graph data and present...
