How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

Learners, in groups, investigate and demonstrate the science behind the development of lightning and thunderstorms.

What does stretching a balloon have to do with equilibrium? Groups explore preconditioning by stretching a balloon to a point of equilibrium. They then measure the amount of force required to stretch the balloon to the same point several...

Seventh graders view "Volcano" by National Geographic Video. They experiment with baking soda and study lava flow. They describe volcano and earthquake patterns. They analyze weather and climate changes and how they relate to the natural...

How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third lesson of the series, learners conduct an experiment, demonstrating the flow of heat...

Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain...

Does assessing Earth Science vocabulary making your head spin? Test scholars' knowledge of revolving and rotating using an interactive tool. The movement of a new planet and its moon is in their hands, allowing them to explore...

Which has the higher IQ, latitude or longitude? Longitude because it has 360 degrees! The interactive introduces the way latitude is measured and why it can never have more than 90 degrees. A handful of challenge questions encourage...

Class members have an opportunity to experience how to use a public key to encrypt information and a private key to decrypt it. Groups create their own public key and encrypt information then develop private keys to decrypt this...

Students telecommunicate and use the US Mail to network students from five biomes in the United States in order to monitor water quality in each area. They have e-mail pals and exchange materials representative of themselves and their...

High schoolers use video, Internet research, graphs and tables, worksheets and hands-on experiments to investigate the properties of water in a lake environment. They work under direction or through an inquiry process.

Fifth graders use Internet sites to complete a study of weather and atmosphere. They compare weather data from cities around the world. They use thermometers, the Beaufort wind scale, and simple weather symbols to measure weather around...

Students participate in a hands-on experiment with different soil structures and the ability of each to carry a specific load. Students take a core soil sample and describe its content layers. Students stand bricks in the soil overnight...

First graders investigate water properties by participating in a hands on experiment. In this ice formation lesson, 1st graders examine real ice cubes in a bowl and identify the reasons why certain cubes melt faster than others. Students...

Students explain how technology leads to a cleaner environment. They gain hands-on experience with ethanol as a fuel alternative.

Students rotate through various hands-on experiment stations to explore the concept and properties of different types of matter. They compare some properties of solids, liquids and gases and describe how matter changes from one state to...

Students study the scientific concepts of biodiversity and conservation through the use of basic equations of population growth and hands-on experiments/simulations. The instructional activity includes a take-home assignment which can be...

Students take a quick examine part of the water cycle, and the combined gas laws. The lesson lead them through the conditions necessary for cloud formation and allow them to create clouds in three different hands-on activities.

Students discover the fundamentals and daily applications of simple machines. They practice basic engineering theory through their hands-on demonstrations of levers.

Students investigate how natural selection influences evolution. They complete a hands-on lab simulation of natural selection, and replicate a real experiment and examine the interplay between selection factors in a population of guppies.

Students use NASA photographs and hands-on activities to compare the amounts of land and water on our planet. They discover that the world has five oceans and that they cover seventy percent of Earth's surface. Students learn how this...

Students explore "matter." In this literacy and three states of matter lesson, students listen to Bartholomew and the Oobleck by Dr. Seuss, then work in groups to explore "oobleck" (cornstarch and water mixture) with their five senses....

Learners examine the importance of vitamin c in their diets and the sources that it comes from.  In this vitamin lesson students complete hands on activities, interpret data and make a bar graph.

Students watch a video and engage in hands-on activities which introduce scientific information made real through re-cognition and understanding the phenomena of gravitational force and how it impacts life on our planet.
