Concentrate to determine the best reflector design. Pairs use the engineering design process to build a reflector to increase the current output of a photovotaic panel. Teams arrive at a final design and present it to the class along...

Have you always wanted to take your science class on an amazing field trip they will never forget? Now you can! Observe the wildlife in an African savanna through trail cameras with a five-part data analysis activity. Learners analyze...

Pupils learn how to control food spoilage by adjusting the food's pH. They see that one of the most dangerous bacteria can grow in food if people don't handle and store food properly. Using knowledge of the bacteria's preferred pH,...

Students meet NASA researchers who describe the relationship between force, energy and motion. They discuss how NASA's experimental X-plane is being tested to make space travel more reliable and show how proportionality and ratios are...

Young scholars study the layer of the atmosphere. In this lesson on the atmosphere, students discuss the composition of the air around us and how the atmosphere was formed. Young scholars create a scale model of the layers of the...

Middle schoolers create a scaled solar system model using colorful beads. In this space science lesson, students convert AU units into metric measurements. They arrange the planets according to their distances from the sun.

In this star magnitude and multiplying decimals learning exercise, students solve 5 problems using the magnitudes of given stars to determine which stars are the brightest, they determine the magnitude differences of stars and they sort...

For this brightness of stars worksheet, high schoolers answer 7 questions about the apparent magnitudes of stars, the sun, and the moon. They compare the brightness of stars, galaxies, astronomical objects and the sun.

Students explore the concept of Venn Diagrams through word problems. In this Venn Diagram lesson, students solve word problems about groups of people using Venn Diagrams. Students use survey results about MySpace and Facebook in a Venn...

Students determine the coefficient of friction for different surfaces. In this physics lesson, students identify the factors that affect friction. They collect data and write a formal lab report.

Students identify ecological elements and their factors on species, populations and food webs. They analyze ecosystems for these elements and research how these factors influence species survival rate. Predictions on conditions over time...

Students use regions to analyze the locational patterns of culture groups at various scales. They discern the basics of region identity by discovering his/her "Home" Region through the examination of criteria in his/her "backyard." In...

Young scholars study the environment and interactions of living organisms. They identify abiotic and biotic factors and create a foldable and vocabulary cards. They create a poster illustrating soil and watch a video to study symbiosis.

Students work individually, or with partners, to develop a design for a greenhouse, and calculate space requirements, equipment needed and cost of operation. They construct a scale model of the greenhouse.

In this geologic time worksheet, students will define the difference between eras, periods, and epochs in the geologic time scale. Students will also look at the role of geological events and fossils. This worksheet has 10 short answer...

Students apply basic time management skills to their lifestyle and implement study skills. Also, they should be able to implement management techniques in their daily lives as well. Students list activities and assignments and determine...

Students study the pH scale and sources of acid precipitation.  For this acid rain lesson students complete a lab on acid rain then complete a handout.

Students investigate the concepts of force and motion. They describe how motion is created by force. Also students define a simple machine and the factors of application to creating force or motion. They analyze the plans of Leonardo De...

Students examine reasons for deforestation and become familiar with Madagascar and its culture, while describing biological and abiotic components of a rainforest, and looking at aspects that must be addressed to resolve the issue of...

Students conduct a variety of investigations to see how water, heat, and salinity affect the flow of the world's ocean currents,as well as, explore many factors that affect the flow of the world's ocean currents. They also describe in...

Students examine the functions of the kidney and its place in the urinary system. They discuss how astronauts go the bathroom in space, examine labeled diagrams of the urinary system, and draw a large scale drawing of the excretory...

Students conduct a pH probe of various household products including both bases and acids. In groups, they use litmus paper to test such liquids as amonia, vinegar, and detergent to discover which are acids and which are bases. Finally,...

Students explore wetlands. In this ecology lesson, students visit a wetland site and collect data about the wetland functions. Students record their results and use the data recorded to rate the wetland site on its function.

Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...
