This is an open inquiry lab that can be done in approximately 15-20 minutes with a few household materials. It dramatically, yet simply, illustrates the condition of color change and the formation of gas (bubbles) as a result of a chemical change.

Students will be conducting a "wander and wonder" in a local park, where they will observe their surroundings and its impact for animals. After discussion, a guided wander and wonder will be taken with the teacher to provide more guidance. Questions will be asked to help students begin to understand how environmental changes impact animals. Students will used digital photography to document these changes and put in their science notebooks as a way to help conclude information.

In this lab activity, students investigate three aquatic ecosystems to determine the relative pollution index and the water quality of each ecosystem. Students collect and analyze benthic organisms found in each system in order to conduct a water quality assessment.

In this classroom lab activity, students will work with a plastic cup, straw, and drinking water to gain a better understanding of how atmospheric pressure works.

In this lab activity, students investigate the differences of current in series, parallel, and complex circuits through the building of a small model house containing the different types of circuits.

In this lesson, students will download two historic datasets from NCDC: Global Summary of the Day (GSOD) daily temperature data and Historic Global Historical Climatology Network (GHCN) monthly temperature data. After importing the data into Microsoft Excel, they will graph and compare daily to monthly temperatures for Barrow, Alaska, and repeat this process for Key West, Florida. They will then compare these patterns to other temperature trends in the United States and globally.

In this lesson, students will learn about weathering and erosion. Then students will be placed in small groups to do simple experiments that illustrate a type of weathering or erosion.

This lesson describes the technique of preparing "GIS-ready" data and shows how to map that data and conduct basic analyses using a geographic information system (GIS). First, students will download and format near real-time and historical earthquake data from the USGS. Using latitude and longitude fields, they will then plot these data in a GIS. Next, they will analyze patterns by querying records and overlaying datasets. Finally, students will examine earthquake distributions, monitor current earthquake activity, and try to predict where the next big earthquake will occur on Earth.

In this physics lab, students investigate the difference between series and parallel circuits using wire, light bulbs, and D batteries.

In this lesson, students will use sand to build a mountain and then use a straw and watering can to simulate wind erosion and water erosion. Students will make observations and then propose ways to slow the erosion and/or speed the erosion. Students will be able to relate the erosion processes to weathering and sediment deposition.

In this activity, students will experiment with different styles of paper airplanes, create questions to test and design experiments that will allow them to gather data related to their question. They will record their data, using graphs where appropriate, and present their findings to the class using their evidence to support their thinking.

In this investigation, students will learn that speed, velocity, and changes in velocity are the result of the action of forces on objects such as friction. Students will construct a simple, balloon powered car and race it on three different surfaces. Students will analyze their car's performance, identify design flaws and apply knowledge to improve their car. They will also graph class results for each of the three surfaces.

In this lab activity, students are given a random sample of the fictitious element "M&Mium." The sample contains at least three different isotopes of M&Mium. The students will design and carry out a procedure to determine the average atomic mass of the element M&Mium.

In this lab activity, students will complete a simple demonstration that introduces students to kinetic theory.

In this classroom activity, students investigate why magnets attract certain objects and how the magnets can attract or repel each other. Students will observe, question, and investigate how the magnets interact with each other and the objects around them.

In this Nature Center activity, students will identify microbes found in a pond or creek. They will collect samples using a Petri dish.

In this lesson, students will make a flip book to illustrate the different phases of the moon by cutting out pre-printed pictures of the different phases and putting them in order.

In this activity, students will collect and analyze data of their walking speed. They will compare their speed to an outside speed walker. They will determine their speed every 20 meters up to 100 meters. They will complete five trials to determine average time for each of the 20-meter segments. The students will write a lab report describing their results.

In this activity, students will study speed, measure and record time and distance, then graph results.
