Curated OER
Improving the HVAC System
Learners describe the components of an HVAC system and determine which factors influence how efficient the system can be. They work together to develop hypotheses about the systems and their cost effectiveness and efficiency.
Curated OER
Comparing Data
Eighth graders create a survey, gather data and describe the data using measures of central tendency (mean, median and mode) and spread (range, quartiles, and interquartile range). Students use these measures to interpret, compare and...
Curated OER
Energy Sources
Students identify natural resources and describe the difference between renewable and non-renewable resources. They also identify the disadvantages and advantages of the resources.
Curated OER
Mendelian and Non-Mendelian Heredity
Tenth graders discuss their physical features, and why they look the way they do. They listen as the teacher discusses DNA, alleles, and dominant or recessive genes. Students perform an experiment with different colored markers...
Curated OER
Camouflage
Third graders collect insects and various bits of the insects' habitats in order to develop an understanding of how camouflage makes the insect fit to survive in its environment.
Curated OER
A Siouan Village
Fourth graders examine the artifacts obtained from an excavated Siouan village site. They make inferences about the people who once lived there based on the artifacts and complete a Research Team Report.
Curated OER
Shadows of North Carolina's Past
Learners construct a timeline of four major culture periods in Native American history from studying archaeological evidence cards.
Curated OER
Inference By Analogy
Students infer the use or meaning of items recovered from a North Carolina Native American site based on 17th-century European settlers' accounts and illustration.
Curated OER
Tree-Ring Dating
In this tree-ring dating activity, students use activity sheets to determine a tree's age and to observe changes in climate from the tree-rings. Students investigate how archaeologists use tree rings to date evidence and they answer 5...
Curated OER
Walking Magic
Students conduct experiment with water striders by placing the insect in two different solutions and discuss their observations. They discover that weight and surface area are important factors in their experiment.
Curated OER
A Tour Down the Hudson River
Students discuss how the Hudson River is an ecosystem made up of both biotic and abiotic factors. They view the PowerPoint the Journal Down the Hudson River. Students become aware of where the Hudson River begins and ends, the plant and...
Curated OER
Zebra Mussel Population Simulation
Learners are taught how to format and enter data into an Excel spreadsheet. They make a graph, and interpret graphed data. Students discuss the possible impacts of zebra mussels on the Hudson river. They graph zebra mussel data.
Curated OER
Analyzing the Relationship between Snowpack and River Flow
Learners use the Internet to research current and past snowpack levels and river gauging station readings. They determine the relationship between snowpack and river flow. They predict future river flow.
Curated OER
The Floristic Relay: A Game to Teach Succession
Students investigate the concept of succession and plant community dynamics. They play a game in order to conduct multiple experiments while playing. The interest of the game is useful for keeping student interest throughout the activity.
Curated OER
Tie Dye
High schoolers practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...
Curated OER
Dissolved Oxygen and Temperature
Students are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...
Curated OER
Dissolved Oxygen Introduction
Students are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...
Curated OER
Is Our Water Healthy?
Students test water for a least one chemical characteristic. They hypothesize how a storm event might change the chemical characteristics of a stream. Students collect water samples and use the chemical test to test the water.
Curated OER
Aquatic Ecosystem Exploration
Students visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for...
Curated OER
What If There's No Light?
students discuss the importance of light and the consequences of living without it. Using a plant as a demonstration, students predict and observe what happens to a plant when it does not receive enough light. In groups, they experiment...
Curated OER
Runoff: Intro to Watersheds
Young scholars are taught that a watershed is, what types of basic land cover are impermeable and permeable to water. They trace the flow of water around their school and around their home. Students determine what watershed their school...
