Learners explore the power of political messages contained in visual artifacts and examine the political messages conveyed by the illustrations that appeared on personal stationery used during the Civil War. They create and describe a...

Students explore the active layer above permafrost and investigate various factors on the insulation value of the active layer.  In this energy transfer lesson, students conduct and experiment to determine the effects of snow cover,...

Students determine sea ice thickness, concentration, and floe size by reading egg codes.  In this sea ice conditions lesson, students color code a map based on prescribed criteria and use the maps to identify changes in sea ice...

Students explore how enzymes are important in the chemical reactions of all living things.  In this enzymes and catalysts lesson students complete an activity to see how enzymes change living things.

Twelfth graders examine the misconceptions of Newton's laws of motion.  In this motion and gravity instructional activity students interpret data and see the effects of gravity. 

In this making observations:  candle activity worksheet, students write observations of an unlit candle, then write observations of a lit candle, then sort them as quantitative or qualitative observations.

Eighth graders research about their chosen ecosystem. In this life science lesson, 8th graders play the role of travel agents and create a travel brochure. They share this in class.

Students investigate the concepts of conservation of mass and simple chemical reactions. Students complete lab experiments and record all observations as well as conduct experiments on their own to determine which reactions created...

Students study changes in the environment using a microscale experiment. In this environmental science lesson, students construct a modified "Winogradsky Column" to observe bacteria activities. They record observations and formulate a...

Students are introduced to the characteristics of trigonometric functions. In groups, they analyze graphs of sine and cosine to determine the lengths of a triangle. They compare and contrast the graphical and numerical characteristics...

Students experiment with inner tubes, weights, flasks, and pistons to demonstrate the gas laws. In this molecular motion lesson, students demonstrate pressure as a force per area. They conduct an experiment to show the relationship...

Young scholars examine forests as a renewable resource and conservation practices.  In this conifers lesson students complete a lab activity on the different types of wood. 

Students examine parallax and angular measurements.  In this investigative lesson students calculate distances of objects and map their results.

Communicate chemistry clearly with a concise guide to writing chemical equations. It covers everything from the parts of a chemical equation to the different types of reactions that budding chemists may encounter.

Students double check their data collections of Top 20 singles that they've been collecting for several days. Types of data is reviewed in detail and a variety of questions are asked for retention factors of mastery. They draw a tally...

Students use the scientific method to determine the properties of various kinds of paints, use collected data to identify paint samples that are not properly labeled and use proper science safety techniques while working with chemical...

Students discover that foods are organized into groups of similar items by developing vocabulary to enhance verbal discussion i.e., real experiences provide the foundation for thoughtful discussion and critical thinking. They then...

Sixth graders distinguish between an observation and an inference distinguish between quantitative and qualitative observations of a scientific experiment. They record and organize data collected during an experiment.

Students explore mechanical friction. They perform experiments to observe the direction of mechanical motion and the difference between rolling and sliding friction. Data results on the experiments are recorded and students answer...

Young scholars explore the behavior of crickets during courtship. They measure the number and types of interactions between household crickets. Students discriminate between quantitative and qualitative observations. They collect data...

Students are given a coin to observe and make inferences about. Using a worksheet, they make two columns to list their observations and inferences in an organized manner. They develop a hypothesis based on one of the inferences and...

Students use quantitative data that they gather to figure out where there is an ore body in their model. They describe how geologists could use similar information in order to figure geologic patterns and geologic history for a specific...

Students work in small groups and use a hand-held vacuum pump with a balloon under the dome with some air. Another deflated balloon is attached to the end where the air goes out. As the air is drawn out of the dome the first balloon with...

Students examine kinds of data used to report statistics, and create their own statistical report based on any of the four sources of media information (Internet, newspaper, TV, magazine).
