Gwynns Falls
Middle schoolers investigate the question: What is the impact of urban development and expansion on the health of a decidious forest ecosystem and humans? They examine the issue of land development by responding to a specific scenario...
Curated OER
Blood Business
Students identify the different kinds of blood. In this biology lesson, students investigate the antigens, agglutinins and Rh factor using their own blood. They use Punnett squares to predict blood type of offspring.

Collisions Lesson
Tenth graders explore the role that collisions and near collisions of galaxies play in determining the shape of galaxies. They model the collision of disk shaped and spherically shaped galaxies.
Curated OER
Exploring With Photograms
Students observe the interaction between energy absorbed, reflected or transmitted through an object in a photochemical process with a classroom demonstration.
Curated OER
Sensor Challenge
Learners develop a pseudo code flowchart for their robotic program. In this physics instructional activity, students construct a robot that can navigate through certain obstacles. They test their robot and present them to class.
Curated OER
Circuit Boards
Students explore circuit boards. They determine that a complete circuit is needed to light the bulbs, experiment with the boards to develop strategies for finding where the hidden connections are, and develop strategies that can be used...
Curated OER
Moving Along
Learners are introduced to the concept of motion. In groups, they practice calculating the rate, time, and distance of various objects on a variety of surfaces. To end the lesson, they apply the same principles to those objects moving...
Curated OER
Robot Movement Lab
Students program a robot that can perform certain methods. In this robotics instructional activity, students discuss the pros and cons of each method. They present their finished project in class.

Testing Soils for Garden Planting
Sixth graders collect soil samples and record the location of the samples by using GPS.
Curated OER
Pollution Solution
Fourth graders examine how trees help to absorb the pollution that is emitted from automobiles. They review the process of photosynthesis and determine how forest management is important on their reservation. They think about the...
