Coastal Dynamics
Life's a beach! The 16th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program first examines different types of coasts and how they form. An activity then has learners investigate the shoreline...
Rainforest Alliance
Trees and Carbon
You'll find everything but the kitchen sink here ... or just a carbon sink. In the activity, pairs or groups of middle school learners go outside and measure a tree's circumference and height to estimate its carbon storage potential and...

Modeling Sizes of Planets
The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Energy Transfer and Transformation
When you take a simple task and create an exceptionally difficult way to complete it, it is known as a Rube Goldberg machine. These machines are filled with many types of energy transfers and energy transformations. Here, pupils...
Curated OER
Liquid Rainbow
Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Greenhouse Gas Lab
Pupils compare the ability of a sample of carbon dioxide gas to
absorb thermal energy compared to a sample of air. They build a visual representation of the greenhouse effect to illustrate the heat-absorption of
atmospheric carbon dioxide.
