Students redesign and justify the packaging used in consumer products. Design criteria include reducing the amount of packaging material by 25%.
In the Arizona desert, farmers depend on an ample supply of irrigation to grow their crops. As climate changes, irrigation managers face a host of issues to keep the water flowing.
The marine environment is unique and because little light penetrates under water, technologies that use sound are required to gather information. The seafloor is characterized using underwater sound and acoustical systems. Current technological innovations enable scientists to further understand and apply information about animal locations and habitat. Remote sensing and exploration with underwater vehicles enables researchers to map and understand the sea floor. Similar technologies also aid in animal tracking, a method used within science and commercial industries. Through inquiry-based learning techniques, students learn the importance of habitat mapping and animal tracking.
Plastic is in the ocean. We all know it. But how did it get there? Why did no one see it coming? Is it really that big of a problem? Learn more through exploring this interactive map and receive challenges to help you tackle the plastic problem in your own community.
The following lesson is an introduction to the ideas and implications of animal tracking. Animal tracking is a useful method used within science and commercial industries. For instance, when planning the development coastal areas, animal presence and movement should be taken into consideration. The lesson engages students in an activity to monitor animal foraging behavior on a spatial scale. The students will break into groups and track each other's movements as they move through a pre-determined course. The results will be recorded both individually and collaboratively in an attempt to understand animal movement regarding foraging behavior. Students will also engage in a creative design activity, focusing on how they would design a tag for a marine animal of their choice. In conclusion, instructors will query the class on data interpretation and how spatial information is important in relation to commercial, conservation, and scientific research decisions.
Students leach organic matter from soil to create a water sample with high dissolved organic matter content (DOM), and then make filters to see if the DOM can be removed. They experience the difficulties of removing DOM from water, and learn about other processes that might make DOM removal more effective.
Students learn how to find the maximum power point (MPP) of a photovoltaic (PV) panel in order to optimize its efficiency at creating solar power. They also learn about real-world applications and technologies that use this technique, as well as Ohm's law and the power equation, which govern a PV panel's ability to produce power.
Students are introduced to the concept of light pollution by investigating the nature, sources and levels of light in their classroom environment. They learn about the adverse effects of artificial light and the resulting consequences on humans, animals and plants: sky glow, direct glare, light trespass, animal disorientation and energy waste. Student teams build light meters using light sensors mounted to LEGO® MINDSTORMS® NXT intelligent bricks and then record and graph the light intensity emitted in various classroom lighting situations. They are introduced to the engineering concepts of sensors, lux or light meter, and lumen and lux (lx) illuminance units. Through this activity, students also learn how to better use light and save energy as well as some of the technologies designed by engineers to reduce light pollution and energy waste.
Through investigating the nature, sources and level of noise produced in their environment, students are introduced to the concept of noise pollution. They learn about the undesirable and disturbing effects of noise and the resulting consequences on people's health, as well as on the health of the environment. They use a sound level meter that consists of a sound sensor attached to the LEGO® NXT Intelligent Brick to record the noise level emitted by various sources. They are introduced to engineering concepts such as sensors, decibel (dB) measurements, and sound pressure used to measure the noise level. Students are introduced to impairments resulting from noise exposure such as speech interference, hearing loss, sleep disruption and reduced productivity. They identify potential noise pollution sources, and based on recorded data, they classify these sources into levels of annoyance. Students also explore the technologies designed by engineers to protect against the harmful effects of noise pollution.
Students observe and discuss a cup and pencil model of a cyclone to better understand the science behind how this pollutant recovery method functions in cleaning industrial air pollution.
In the face of a changing climate, the Tribe is building capacityand climate resiliencethrough forestry management, habitat protection, and an innovative approach to healthy eating.
This site, published by the EPA, discusses the sources of methane emissions, including landfills, coal mining, the oceans and livestock, among others.
Students learn about the remote sensing radio occultation technique and how engineers use it with GPS satellites to monitor and study the Earth's atmospheric activity. Students may be familiar with some everyday uses of GPS, but not as familiar with how GPS technology contributes to our ongoing need for great amounts of ever-changing global atmospheric data for accurate weather forecasting, storm tracking and climate change monitoring. GPS occultations are when GPS signals sent from one satellite to another are altered (delayed, refracted) by the atmosphere passed though, such that they can be analyzed to remotely learn about the planet's atmospheric conditions.
Several times per year, seawater floods some of the streets in Charleston, South Carolina. Taking steps to deal with this "nuisance" flooding can help the city prepare for sea level rise.
Students learn about the advantages and disadvantages of the greenhouse effect. They construct their own miniature greenhouses and explore how their designs take advantage of heat transfer processes to create controlled environments. They record and graph measurements, comparing the greenhouse indoor and outdoor temperatures over time. Students are also introduced to global issues such as greenhouse gas emissions and their relationship to global warming.
As Public Works Director of Nogales, Arizona, Alejandro Barcenas works to ensure a safe and secure water supply for the city’s 20,500 residents. His task isn’t easy: the city is located in an arid region just north of the United States–Mexico border, and its entire supply comes from groundwater.
Half of Nogales’ water comes from alluvial aquifers that are highly responsive to rainfall events. Though this convenient source of water recharges easily, it is also vulnerable to climate-related changes such as reduced precipitation and increased evaporation. The other half of the city’s groundwater comes from a lower-quality source—this water is more expensive to produce. To optimize the use of the two sources of groundwater into the future, Barcenas is contributing to the development of a modeling tool that simulates how the aquifers may change in response to climate.
Students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They explore the natural cycles water, oxygen/carbon dioxide, carbon, nitrogen that exist within the environment.
Climate change adaptation isnt always welcome as a topic of conversation, even among those who could benefit from it. A recent study hints at a possible path forward.
Métis culture will continue to be lived and celebrated when we pass our knowledge on to the generations who follow us.
Everyone is on a learning journey. While exploring historical and contemporary Métis ways of knowing and doing, these learning packages provide knowledge and understanding for students and teachers. Topics include: Traditional Harvesting Methods, Geographical Terms, Music and Dance, Conversational Michif, Beading, and Traditional Foods. The lesson plans and videos highlight Knowledge Keepers walking in the tall prairie grass, Elders preparing la galette (bannock), students learning Michif numbers, and family greeting each other for tea. We hope these resources will assist you in your learning.
