Curated OER
Hess's Law
For this reactions worksheet, students use Hess's Law to calculate the heat gained or lost by different reactions. Students determine if the reaction would occur spontaneously at a given temperature. This worksheet has 9 problems to solve.
Curated OER
Bats and Hot Dogs
Students identify patterns and relationships from data that is collected and solve variables. In this investigative lesson students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.

Pond Life Identification Kit
Young scholars explore ecology and biodiversty. They use the wet-mount procedure to make several slides to view using the microscope and draw what they see.
Curated OER
Around the World
Students explore ways people from around the world are like them. They discuss how geography affects the way people live and work and how culture affects a person's day to day life. Students give a presentation over a chosen country to...
Curated OER
Building A Topographic Model
Students visualize, in three dimensions, features represented by contour lines on a topographic map. They see that the different elevations shown on a two dimensional topographic map can be used to build a 3-D model.

Tree Identification
Students list four ways to identify trees. In this tree identification instructional activity, students use tree identification techniques such as leafs, bark, wood grain, soil type, and climate to create tables and graphs.
Curated OER
Representing Quadratics
Learners represent quadratic equations using different methods. For this algebra lesson, students solve quadratics using substitution, elimination and graphing. They relate quadratics to the real world.
