Students explore the main concepts of astronomy through the eleven lessons of this unit. The past, present, and future methods of studying the science are examined in this unit.

Fourth graders watch an experiment that demonstrates the causes of wind. They design and make an original weather craft.

Seventh graders trace the lava flow of an erupting volcano. In this earth science lesson, 7th graders experiment using baking soda and vinegar. They record and share their observations.

Eighth graders hypothesize what caused the break up of continents. In this earth science lesson, 8th graders study about the events that took place during Mesozoic and Cenozoic Era. They reconstruct a supercontinent and report their...

Fourth graders observe a demonstration experiment showing air pressure. They explain air pressure by completing the worksheet.

Pupils conduct a controlled experiment. They collect data in an organized manner. Students analyze data to reach a conclusion and communicate findings. They explain how city size, temperature, and pollution is related to the air quality.

Second graders become familiar with the lives of penguins including their life cycles, habitats and basic needs. Students will experience the lives of penguins through stories and video.

Students complete a science experiment to study the role of night and day on sleep patterns. In this sleep patterns lesson, students brainstorm about night and day and the causes for the rotations on Earth. Students work in groups to...

Students watch a video on population dynamics. They conduct an experiment where they fill up a designated space with students. They recreate multiplying rabbits using beans.

Students examine how speleothem formations can be simulated. Students follow directions carefully in this laboratory experiment, and keep a written account of everything they observe. After five days, the students share their experiment...

Middle schoolers study the Cassini spacecraft and its travel to Saturn. They discover the results of the space mission and examine images of Saturn that Cassini sent back.

Students explore volume and pressure. Through an activity, students discover what happens in situations when volume is increased but no additional air is able to enter the enclosed space. Students create models and explain their...

Students study the function of lungs. In this lung function lesson, students complete an experiment using balloons to study the way lungs work. Students study a diagram of their lungs and make a hypothesis for their lung capacity...

Students classify clouds as transparent, translucent or opaque. They conduct an experiment to determine the visual opacity of several classroom objects and then conduct further observations of clouds.

Students experiment with soda cans and water to discover why air pressure is greater closer to Earth's surface.

Students identify the control and the variables in the experiment. They describe the growth of plants with and without nitrogen fixing bacteria, then name the bacterium responsible for making nitrogen available to the plant.

Learners work together to construct a model of a water catchment basin. They survey water patterns and complete experiments to see where rain travels and collects. They discover how engineers design structures that help with drainage.

Students experiment with currents caused by temperature variations that simulate the origins and flow of polar bottom currents. They discover water density is affected by temperature and salinity, resulting in deep water currents.

Students use lecture and research to answer the question: Why is the sky blue? students research a variety of other sky phenomena, chart their observations and participate in experiments.

Students using different experiments and activities explore electromagnetic radiation and the effect on the Earth.

Students investigate the concept of an aquifer and use a 2 liter bottle and other materials to conduct a simple lab experiment or demonstration. They calculate the volume of water that can be stored in the aquifer. The lab is used to...

Eighth graders examine how electricity is produced in relation to the atom as well as what causes electric current to flow and what determines how much current flows through a circuit. These and other concepts of transformation of energy...

Students engage in real time interactions with researchers and are exposed to innovative research. They conduct an experiment designed to investigate the strength and maximum deflection of a composite material with and without the use of...

Eighth graders record the temperature change of the beakers. In this general science lesson, 8th graders create their own data table for recording observations. They discuss experimental results and cite real life applications.
