Seventh graders observe that heat is produced when two substances are combined. They brainstorm how, and then experiment to find out which of two chemicals created the heat.

Students construct a simple spectroscope. They observe the emission spectrum produce by a source of light.

Third graders watch a video on the solar system and examine the role of the sun. As a class, they complete a KWL chart and make different color temperature pockets to use during their experiment. In groups, they make predictions about...

Learners see the difference between weight and mass when they examine the method of measuring each of them.

Students use satellite images to track to movement patterns of deer and examine deer behavior. They write stories about a day in the life of a field scientist.

Students take an imaginary hike in two opposite directions along a lake. They view and interpret satellite images and discuss the pros and cons of hydroelectric dams.

Students gain knowledge by measuring time and distance for solving unknowns in an equation. They also will design an airplane and chance to communicate mathematically by writing essays.

Students are taught that they can gather information about objects using the five senses of vision, touch, smell, taste, and hearing. They are told that some sensing, like sight, is done remotely. Students observe how a camera can...

Students identify the processes involved in the water cycle. In this math lesson, students explain what civil engineers and hydrologist do. They watch a video about flooding in Texas.

Students examine the possibilities of communication with other living organisms within our solar system through research and hands on activities, as well as observing and analyzing teacher demonstrations.

Young scholars assess the environmental impact of their transportation choices. They keep a transportation journal and use a website to calculate vehicle emissions for themselves and their class. They evaluate their transportation choices.

Students identify and separate the different zones of the beach by observation. They investigate beach zonation by gathering and comparing sand samples gathered from different areas of the beach.

Third graders measure the heat created at each center.

Students practice plotting temperature data points on a line graph in groups and examine the temperature differences at the same time of year. They graph the temperatures in Lannon, WI, and Mitchell's Plain, SA. After the data has been...

Students recycle discarded automobile tires and create gardening sites for limited space areas.

Learners record data, make observations, and share in experimentation and discussion of numerical experiments.

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.

Learners construct a barometer and collect data on the changes in air pressure. They work is small groups using plastic tubing, corks, and green food coloring. They then use a formula to convert inches of mercury to barometric pressure...

Students watch programs from a series titled "Planetary Landers". As a class, they view a poster of various vehicles that have made their way into space. In groups, they brainstorm the characteristics that should be included when...

Students examine how to plan for prudent use of trees so that we never run out of this natural resource. They determine what the oldest wooden object in their home is and draw picture of it. They observe a cross section of a tree and...

Students set up their own monitoring system. They collect samples from an appropriate sampling site. They analyze data and determine the water quality. They present their information to the class and draw a conclusion.

Students identify the sources of pollution and waste in their community. They examine the process of recycling and how to eliminate some of their family waste.

Students are told that an air tank contains a fixed volume of air under pressure. As air is used, the pressure decreases at a rate that depends on the depth. Students discuss how SCUBA divers calculate the amount of time they can spend...

Learners use standard rulers to measure the length of common classroom items - such as pencils, books, desk tops - in inches and centimeters, and measure weight in pounds. They also answer math questions, such as "How long is the front...
