The activity walks the students through the processes of Photosynthesis and Cellular Respiration.

This write-pair-share activity presents Calculus II students with a worksheet containing several exercises that require them to find the volume of solids of revolution using disk, washer and shell methods and to sketch three-dimensional representations of the resulting solids.

In this example, students are asked to research the effects of Wal-Mart on small town economies, relate those effects to their own town, and draw a conclusion based on those effects.

This activity provides students with a first look at water tension and its role in the life of a water strider.

This activity provides students with a first look at water tension and its role in the life of a water strider.

This activity investigates water when it freezes and how other solid items sink or float in water.

In this science lab, students investigate Newton's Laws of Motion. Students will make and fly water bottle rockets, as well as measure the height of each rocket's flight.

This lab activity is an exploration of Newton's Three Laws, forces and energy. Students will design, build, launch and analyze rocket data.

This activity is a classroom activity where kindergarten students mix the primary colors together to create the secondary colors using pipettes and well trays.

This activity is an introduction to the water cycle where students will use observation, drawing, writing, recording, questioning, and communication to understand the concept of condensation.

This is a field investigation in which students test water quality in 2-3 areas using their own testable question.

This lesson helps grade 3 students understand the difference between Vertebrates and Invertebrates.

This activity is a 3 part lab activity where students create a model of an area in a community. The students test how dirty water flows through their models observing where water is filtered or not. Using what was learned by the models, students will draw a community scene that has man made areas alongside areas that benefit groundwater filtration.

This activity is a classroom based inquiry activity where students will observe how water changes when it is moved through a variety of different mediums. Eventually, the students will take this model to the larger ideas of watershed in the community.

Students build a model of a watershed, apply water to the model, and explore what happens when elements of the watershed are changed.

This activity is a class activity where students gather information of the water cycle, weather and seasons by doing a lab and game that enforces the concepts of the water cycle.

This activity is a field investigation where students gather weather cycle data on seasons and climate. They will graph their observations, share with others and connect weather and seasons together.

In this activity students examine karyotypes from five individuals to try to identify which chromosomes determine gender in humans. This activity is also a good illustration of meiotic non-disjunction.

a. This activity is designed for students to work on their observational skills, and the communications of their observations. They will also learn to pose researchable or testable questions, to give critique (and to receive) critique on their comments and research.
