Students examine tree-ring dating and discuss the lack of water the settlers in Jamestown faced. They create paper tree rings, simulate rain patterns, and describe the history of construction paper tree sequences.

Students investigate seed germination. In this lesson on scientific prediction, students conduct a scientific experiment using oat seeds.

Students examine the cell cycle and how its duration can vary.  In this cells lesson students complete a worksheet and answer questions. 

High schoolers conduct simple sampling of plant and insect biodiversity at ground level in two contrasting environments of their own choosing. They recognize and record different species then compare and contrast species numbers in the...

Students build an aquatic ecosystem using large glass pickle jars.  In this ecology lesson, students build and ecosystem then observe and collect data on the habitats.   In this long term project students observe a...

Ninth graders are introduced to the concept of population. In groups, they research the problems associated with overpopulation and underpopulation. They practice calculating birth and death rates and discus how they can be used to...

Students analyze and record major events that occur in the development of Medaka fish eggs from fertilization to hatching. In small group, students describe the processes involved, creating a timeline of the major events in the...

Students research propulsion, graph data, and interpret the results.

Students investigate classification of different animal groups. In this biology lesson students list characteristics of themselves and others they know to show differences and how they are classified. Students then answer...

Learners use Hudson River salinity data to create a line graph that shows the location of the salt front, and use math skills to explore how this location varies over time. They use the graph to estimate the location of the salt front...

Students identify the stages in the water cycle. They observe a local water source and view the cycle in action. They create their own water cycle using software.

Students 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 and...

High schoolers explore what factors affect the stream flow in a local body of water. They collect data to measure stream flow and discharge and construct a hypothesis concerning the factors affecting stream flow.

Ninth graders encounter various types of numerical information (represented in multiple ways), much of which is abstract and difficult to comprehend. In this lesson, 9th graders will convert given information into bar graphs. In the...

Third graders use metric measuring for model and actual plan in designing a roof garden. They photograph the process, record results in a journal, and plant seedlings in small containers. Finally, 3rd graders complete an acid rain...

High schoolers develop code systems to transmit information between groups. They explore, explain and apply techniques used to transmit remote sensing data to better understand remote sensing images.

Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.

Students explore the differences between surface water and ground water. They collect data using maps and graphs and investigate a Texas river basin and a nearby aquifer. They complete a written report including maps and data regarding...

Learners are able to calculate the population density of a country, and calculate the population density of large cities in that country. They are able to create an appropriate graph to represent their data for that country.

Students are divided into five groups with each group assigned one of the following topics: how coal is formed, how coal is mined, how coal is used to create energy, environmental impact of coal mining, and the benefits of coal energy....

Students demonstrate an understanding of the text by completing a propulsion activity, charting the results, and answering questions that demonstrate an understanding of rocket propulsion.

Ninth graders, after reading the explanation given below, complete the problem-solving activities to demonstrate an understanding of the concepts presented.

High schoolers examine the process of scientific inquiry. They develop twenty questions, categorize the questions, develop a research proposal, analyze data, draw conclusions, and explain how their research connects to the state standards.

Pupils use Curveball to complete the activity to determine how the speed of airstreams changes in relation to changes in the distance of the airstream from the center of the baseball.
