This activity from NOAA Ocean Service is about using aerial photographs to assess the impact of extreme weather events such as Hurricane Katrina. The activity features aerial views of Biloxi, MS post-Katrina and enables students to see evidence of the power of extreme weather on the environment.

Students use aerial photography combined with field observation to interpret the geology of a megascopic anticline-syncline pair exposed in the Ouachita Mountains of central Arkansas. This project focuses on the integration of remotely-sensed data with direct observation to develop and test hypotheses regarding the geology and structure of a well-defined field area. Students construct a geological map and cross-section that synthesize their observations and illustrate the geology of the field area.

Students experiment with a new materialâaerogel. Aerogel is a synthetic (human-made) porous ultra-light (low-density) material, in which the liquid component of a gel is replaced with a gas. In this activity, student pairs use aerogel to simulate the environmental engineering application of cleaning up oil spills. In a simple and fun way, this activity incorporates density calculations, the material effects of surface area, and hydrophobic and hydrophilic properties.

he cost of healthcare is one of the largest personal expenditures worldwide, with residents of the United States spending upwards of $10,000 each year. A significant portion of healthcare costs in the United States and many other countries comes from paying for prescription medications. This unit is designed to give 9-12th grade chemistry, pharmacology, or biology students an introduction to prescription drug costs and what scientific measures can be taken to lower costs. Topics necessary for this unit include the relationship between structure and function, pH, activation energy, the relationship between temperature and reaction rate, catalysts, inhibitors, among additional concepts. This unit functions as an end-of-year project incorporating all of the topics listed above and challenges students to conduct research, design their own strategy to lower drug costs, and prove their viability and cost-saving potential through calculation. Individually or in pairs students must pick a strategy or technology, spend a day or more researching it, two days writing a research paper on it, one day preparing a class presentation, and one day for presentations. Student’s ability to effectively prove the viability of their strategies/technologies as well as estimate the cost savings to consumers will be weighted heavily.

In this activity about light and perception, learners discover how a flash of light can create a lingering image called an "afterimage" on the retina of the eye. Learners will be surprised when they continue to see an image of a bright object after staring at it and looking away. Use this activity to introduce learners to principles of optics and perception as well as to explain why the full moon often appears larger when it is on the horizon than when it is overhead. This lesson guide also includes a few extensions like how to take "afterimage photographs."

This astronomy program is designed for middle school children in out-of-school-time settings. The program explores basic astronomy concepts (like invisible light, telescopes) and focuses on the universe outside the solar system (stars, galaxies, black holes). The program is structured for use in a variety of settings, including astronomy days, summer camps, or year-long afterschool programs. Although session activities build concepts sequentially, each session activity is designed to be freestanding as not all participants may attend every session. A manual provides background information and descriptions of how to conduct each activity. A companion website provides additional information and resources for the program leader.

After the Ice: Our Food discusses changes in historic food sources for Arctic Native Americans. Global climate change is altering yearly cycles of both ice coverage and depth in the Bering Sea. Changes in the ice affect the way local native groups hunt in order to feed their community.

This 7-minute video illustrates how the historic homeland for Arctic Native Americans is being affected by climate change. Shorefast ice and pack ice are present for a shorter part of the year. This has profound affects on the way of life in the Bering Sea region, to the point where the community may have to relocate.

This video discusses how the historic way of life for Arctic Native Americans has changed. Global climate change is altering the ice cycle (yearly coverage, depth, and persistence) in the Bering Sea and weather patterns. Changes in the ice affect the way local native groups are able to hunt for food, and maintain their community.

All biological cells require the transport of materials across the plasma membrane into and out of the cell. By infusing cubes of agar with a pH indicator, and then soaking the treated cubes in vinegar, you can model how diffusion occurs in cells. Then, by observing cubes of different sizes, you can discover why larger cells might need extra help to transport materials.

On November 26, 2020, trade unions in India reported that over 250 MILLION people took part in a strike. What could prompt such massive protest? Farming. Today, we’re going to take a closer look at GMOs, which are organisms whose DNA has been modified in a laboratory, and examine the impact of one GMO in particular, Bt Cotton, in the agrarian crisis in India.

This STEM challenge can be used during an air unit. Students work together in groups to create a parachute for a lego person. Students are able to find ways to best maximize air resistance. The students need to find the best way to increase the time that the lego person stays in the air when dropped from the second floor to the first floor.

This lesson plan engages students in a real-life exploration of climate change as it is affected by greenhouse emissions from vehicles. The aim of this activity is for students to realize the impact of vehicle use in their family and to give students the opportunity to brainstorm viable alternatives to this use.
