Curated OER
Weather Records
Students write newspaper articles using a "weather record" worksheet and information they find in newspapers.
Curated OER
Frozen Film
Students are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.
Curated OER
Spectral Surprise
Students experience a model that produces, separating, and displaying spectral colors.
Curated OER
Decomposers at Work!
Students design and conduct investigations that illustrate the process of decomposition. After a lecture/demo, students simulate the process of soil composting in the classroom. They closely chart the decomposition of their soil.
Curated OER
Multiplying Microbes
Students examine environmental conditions that effect bacteria growth. They culture bacteria, design and conduct an experiment, and identify the conditions that effected the bacteria growth using the scientific method.
Curated OER
Precipitation
Fourth graders identify the conditions that create rain. They read and discuss weather records, and write a news article that includes factual information fom one of the listed weather records.
Curated OER
Optional Laboratory: Comparing Soil Temperatures In Sun and Shade
Students work together to test the temperatures of different soils in shade and sun. They make their own hypothesis before beginning the experiment. They record their data and discuss as a class.
Curated OER
Get Out in the Field
Students visit a shoreline--of an ocean, a lake, a pond, a riverbank, etc., survey it and record what they find there. They map the shoreline and surrounding area and conclude where potential waterfront projects could occur.
Curated OER
Classifying Candy III
Students create a classification tree based on grouping candy with eight different properties. This allows students to understand how living things are classified.
Curated OER
Testing Foods
Learners perform an experiment using brown paper bags to determine which foods have oil in them. This task assesses student's abilities to make simple observations and inferences from them.
Curated OER
Mystery Boxes
Students make observations about Mystery Boxes that their teacher has made up and describes the motion of the object inside the box and hypothesizes it's shape based on their observations.
Curated OER
Color Dots 3
Students make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.
Curated OER
Gazillions!
Second graders determine the total value of a collection of coins. They convert money and make money exchanges. Students create and solve money-story problems. They demonstrate the ability to summarize conversations and discussions.
Curated OER
What If the Reef Dies?
Learners complete four activities to investigate how reef ecology can change. They perform experiments to show how sewage discharge can affect a marine ecosystem, look at substances that don't dissolve in water, examine wave action...
Curated OER
Is It Hot in the Light?
Third graders make observations about the temperature of items in direct sunlight. In groups, they discuss why asphalt, brick and cement are warmer than items surrounding them. To end the lesson, they examine how heat transfers energy...
Curated OER
Carbon Dioxide: The Heat is On
Young scholars examine the greenhouse gases affecting the atmosphere. In groups, they participate in activities in which they examine the effects of heat on the atmosphere and phytoplankton. They research how the phytoplankton differ...
Curated OER
Smog Be Gone
Students begin the lesson by identifying greenhouse gases. In groups, they observe and record the effect of the gases on the atmosphere and the temperature of the Earth. They participate in activities that describe the role of...
Curated OER
Thermal Energy Transfer - Conduction
Students examine how heat passes through a pane glass window. In this energy transfer lesson students complete a lab activity.
