Students will breed fruit flies through several generations and record their data using mathematical models in order to demonstrate the inheritance of trait variations.

Mosquito! is a freely available community research guide developed by the Smithsonian Science Education Center (SSEC) in partnership with the InterAcademy Partnership as part of the Smithsonian Science for Global Goals project. These Smithsonian Science for Global Goals community research guides use the United Nations Sustainable Development Goals (SDGs) as a framework to focus on sustainable actions that are defined and implemented by students.

Mosquito! is a module broken up into seven parts. Each part contains a series of tasks to complete. Each task contains additional resources to support that task. We have provided a suggested order for the parts and tasks. However, the structure of the guide hopefully allows you to customize your learning experience by selecting which parts, tasks, and resources you would like to utilize and in what order you would like to complete them.

Students are introduced to the parameters of an engineering challenge in which their principal has asked them to devise an invisible security system to cost-effectively protect a treasured mummified troll, while still allowing for visitor viewing during the day. Students generate ideas for solving the grand challenge, first independently, then in small groups, and finally, compiled as a class.

Students are introduced to the futuristic concept of the moon as a place people can inhabit. They brainstorm what people would need to live on the moon and then design a fantastic Moon colony and decide how to power it. Students use the engineering design process, which includes researching various types of energy sources and evaluating which would be best for their moon colonies.

The Next Generation Science Standards (NGSS)* call for students to use the practices, concepts and content of science and engineering to understand phenomena and solve problems that are relevant to their lives. Starting from a student’s own experiences and community makes the science meaningful and increases engagement while helping students understand how global issues like climate change are present and addressable in their lives. In this series we examine how you can use the new science standards and your community to understand and address real world environmental problems and explore together how to integrate NGSS into your district’s classroom science units.How does engineering relate to solving problems in your community? Learn how IslandWood is using the engineering design process to help students investigate local stormwater problems, seek stakeholder input, and develop solutions. Explore what is involved in putting student ideas into action including possible real-world constraints, practical small-scale solutions potential partners, and mini-grant options. We’ll work together to figure out a plan for the topics and students you teach.

Student pairs experience the iterative engineering design process as they design, build, test and improve catching devices to prevent a "naked" egg from breaking when dropped from increasing heights. To support their design work, they learn about materials properties, energy types and conservation of energy. Acting as engineering teams, during the activity and competition they are responsible for design and construction planning within project constraints, including making engineering modifications for improvement. They carefully consider material choices to balance potentially competing requirements (such as impact-absorbing and low-cost) in the design of their prototypes. They also experience a real-world transfer of energy as the elevated egg's gravitational potential energy turns into kinetic energy as it falls and further dissipates into other forms upon impact. Pre- and post-activity assessments and a scoring rubric are provided. The activity scales up to district or regional egg drop competition scale. As an alternative to a ladder, detailed instructions are provided for creating a 10-foot-tall egg dropper rig.

The original Native American story component lesson was developed as part of an Office of Superintendent of Public Instruction (OSPI) and Washington State Leadership and Assistance for Science Education Reform (LASER) project funded through an EPA Region 10 grant. The stories were told by Roger Fernandes of the Lower Elwha Klallam tribe. Mr. Fernandes has been given permission by the tribes to tell these stories.As these lessons and stories were shared prior to the adoption of the Washington State Science Learning Standards in 2013, there was a need to align these stories with the current science standards. This resource provides a current alignment and possible lesson suggestions on how these stories can be incorporated into the classroom. This alignment work has been funded by the NGSS & Climate Science Proviso of the Washington State Legislature as a part of North Central Educational Service District's award.

Student groups are challenged to design and construct model towers out of newspaper. They are given limited supplies including newspaper, tape and scissors, paralleling the real-world limitations faced by engineers, such as economic restrictions as to how much material can be used in a structure. Students aim to build their towers for height and stability, as well as the strength to withstand a simulated lateral "wind" load.

Acting as biomedical engineers, students design, build, test and redesign prototype heart valves using materials such as waterproof tape, plastic tubing, flexible plastic and foam sheets, clay, wire and pipe cleaners. They test them with flowing water, representing blood moving through the heart. As students creatively practice engineering problem solving, they demonstrate their understanding of how one-way heart valves work.

This hands-on experiment will provide students with an understanding of the issues that surround environmental cleanup. Students will create their own oil spill, try different methods for cleaning it up, and then discuss the merits of each method in terms of effectiveness (cleanliness) and cost. They will be asked to put themselves in the place of both an environmental engineer and an oil company owner who are responsible for the clean-up.

Students work in engineering teams to optimize cleaner energy solutions for cooking and heating in rural China. They choose between various options for heating, cooking, hot water, and lights and other electricity, balancing between the cost and health effects of different energy choices.

Sea level is rising due to climate changes that result from increased emissions of greenhouse gases. In this storyline, students will explore mechanisms of sea level rise and the impacts on Indigenous peoples along with other groups such as urban communities. Natural hazards such as erosion, storm surges, and flooding are intensified by sea level rise. The effects on natural resources, the economies built from those natural resources, and land usage in general can be predicted by utilizing current and historical data.

Urban forests provide many benefits to a community and can minimize the human impact on the environment. Students will explore the impacts an urban community has on the environment. Students will discover the role trees play in an urban community and how trees can affect the ecosystem, human wellbeing, and provide economic value. Students will explore Indigenous relationships with trees. During the course of this storyline, students will measure and monitor urban forest ecosystem benefits, perform a field investigation, and design a development to minimize negative environmental impacts

The Pack is a digital game that encourages learners to use Computational Thinking (CT) to solve problems they encounter in the futuristic world of Algos, where healthy ecosystems have faltered and water and food are scarce. Throughout the game, players must find food sources to attract their own Pack of Algos creatures. These creatures have various functions (like digging, moving, grabbing, and bumping) that can help the player collect seeds and bring water to dry areas. Creatures can be combined to form algorithms that perform complex tasks and overcome challenges. Players’ use of these algorithms is the key to finding all of the seeds and restoring harmony to Algos!

The Pack game and supplemental activities are designed to support middle schoolers in engaging with Computational Thinking concepts and practices while reinforcing basic scientific reasoning. The supplemental activities encourage players to reflect on their gameplay through the lens of Computational Thinking and to explore how solving problems in the game connects to the ways they can solve problems in class and beyond. The supplemental activities can be implemented in a classroom, as part of an after-school program, or even as an activity for families to do together at home.

Student groups are challenged to create food packages for specific foods. They focus on three components in the design of their food packages; the packages must keep the food clean, protect or aid in the physical and chemical changes that can take place in the food, and present the food appealingly. They design their packaging to meet these requirements.

Using paper, paper clips and tape, student teams design flying/falling devices to stay in the air as long as possible and land as close as possible to a given target. Student teams use the steps of the engineering design process to guide them through the initial conception, evaluation, testing and re-design stages. The activity culminates with a classroom competition and scoring to evaluate how each team's design performed.

Students investigate how different riparian ground covers, such as grass or pavement, affect river flooding. They learn about permeable and impermeable materials through the measurement how much water is absorbed by several different household materials in a model river. Students use what they learn to make recommendations for engineers developing permeable pavement. Also, they consider several different limitations for design in the context of a small community.

To gain a better understanding of the roles and functions of components of the human respiratory system and our need for clean air, students construct model lungs that include a diaphragm and chest cavity. They see how air moving in and out of the lungs coincides with diaphragm movement. Then student teams design and build a prototype face mask pollution filter. They use their model lungs to evaluate their prototypes to design requirements.

Students follow the steps of the engineering design process while learning more about assistive devices and biomedical engineering applied to basic structural engineering concepts. Their engineering challenge is to design, build and test small-scale portable wheelchair ramp prototypes for fictional clients. They identify suitable materials and demonstrate two methods of representing design solutions (scale drawings and simple models or classroom prototypes). Students test the ramp prototypes using a weighted bucket; successful prototypes meet all the student-generated design requirements, including support of a predetermined weight.

Students use their knowledge of scales and areas to determine the best locations in Alabraska for the underground caverns. They cut out rectangular paper pieces to represent caverns to scale with the maps and place the cut-outs on the maps to determine feasible locations.
