In this chemistry lab experiment, students explore the properties of color using chromatography. Students will observe and compare color patterns to differentiate compositions of various colors. Students gather data on color patterns and develop new experimental questions based on their data.

This activity is a field investigation where student create a life-sized contour map and discuss why some contour lines are different from others.

Students observe the decomposition of a pumpkin under controlled circumstances. These observations are used to take notes and develop questions.

This is an exploratory activity involving matter and density. There are many assessment pieces including a laboratory.

This activity is an interactive demonstration of the concept of density with a guided inquiry component.

This activity is a guided inquiry of how molecules move in liquid. Students develop questions, use their observation skills to describe what they saw, record and analyze their findings, and use their data to begin to hypothesize what is happening in the investigation.

This activity is a field collection investigation where students gather earth materials and make observations about their collection that leads them to discuss the nature of Earth surface and how it is changing.

In this activity students use a simple model of the moon to do an experiment to see how impact craters are formed. The lesson worksheets are differentiated and students are put into pre-determined teams by ability to conduct the experiment.

This activity is a field investigation in which students identify organisms and their energy sources. Students collect data and create a food web that explains how the organisms in their ecosystem are related.

This activity is a group lab activity where students explore beginning electrical circuits.

In this lab, the students will test a variety of materials to discover which items are conductors and which items are insulators. They will discuss, classify, record data, and develop new questions relating to electricity.

This activity is an indoor lab where students build a model to observe the effects of weathering and erosion.

This activity is an investigation where students gather information about the rate of evaporation, interpret their findings, and apply this knowledge to the water cycle.

This activity is a lab investigation in which students observe the rate of generation of hydrogen gas from a reaction, and then modify the procedure to compare another variable affecting the rate of this reaction.

In this field activity students will discover some of the factors that influence weathering of rock by making observations, asking questions and completing an investigation of their own design in a local cemetery.

Students will determine a testable question and create an experiment related to flight of paper airplanes. They will gather and record data and present their findings to classmates.

This activity continues the idea as to why objects sink or float using the mathematical formula density equals mass divided by volume.

This is a guided inquiry-based lab that investigates forces exerted on a group of student-designed and engineered "balloon cars". Each group of students is then challenged to build a "balloon car" that travels a maximum distance.

This activity is a field investigation where students will gather data on speed, acceleration, gravity, friction, and forces. They will design and conduct an investigation.
