In this hands-on activity, students investigate different methods—aeration and filtering—for removing pollutants from water. Working in teams, they design, build and test their own water filters—essentially conducting their own "dirty water projects." A guiding data collection worksheet is provided.

Students learn the different airplane parts, including wing, flap, aileron, fuselage, cockpit, propeller, spinner, engine, tail, rudder, elevator. Then they each build one of four different (provided) paper airplane (really, glider) designs with instructions, which they test in three trials, measuring flight distance and time. Then they design and build (fold, cut) a second paper airplane design of their own creation, which they also test for flight distance and time. They graph the collected class data. Analysis of these experiments with "model" airplanes and their results help them see and figure out what makes airplanes fly and what can be changed to influence the flying characteristics and performance of airplanes.

In this service-learning engineering project, students follow the steps of the engineering design process to design an assistive eating device for a client. More specifically, they design a prototype device to help a young girl who has a medical condition that restricts the motion of her joints. Her wish is to eat her favorite food, pizza, without getting her nose wet. Students learn about arthrogryposis and how it affects the human body as they act as engineers to find a solution to this open-ended design challenge and build a working prototype. This project works even better if you arrange for a client in your own community.

Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams (girders) and columns (piers) of simple bridge design. They learn the steps that engineers use to design bridges by conducting their own hands on associated activity to prototype their own structure. Students will begin to understand the problem, and learn how to determine the potential bridge loads, calculate the highest possible load, and calculate the amount of material needed to resist the loads.

Students take advantage of the natural ability of red cabbage juice to perform as a pH indicator to test the pH of seven common household liquids. Then they evaluate the accuracy of the red cabbage indicator, by testing the pH of the liquids using an engineer-designed tool, pH indicator strips. Like environmental engineers working on water remediation or water treatment projects, understanding the chemical properties (including pH) of contaminants is important for safeguarding the health of environmental water sources and systems.

In a class demonstration, the teacher places different pill types ("chalk" pill, gel pill, and gel tablet) into separate glass beakers of vinegar, representing human stomach acid. After 20-30 minutes, the pills dissolve. Students observe which dissolve the fastest, and discuss the remnants of the various pills. What they learn contributes to their ongoing objective to answer the challenge question presented in lesson 1 of this unit.

While building and testing model rockets fueled by antacid tablets, students are introduced to the basic physics concepts on how rockets work. Students revise and improve their initial designs. Note: This activity is similar to the elementary-level film canister rockets activity, but adapted for middle school students.

Students observe an in-classroom visual representation of a volcanic eruption. The water-powered volcano demonstration is made in advance, using sand, hoses and a water balloon, representing the main components of all volcanoes. During the activity, students observe, measure and sketch the volcano, seeing how its behavior provides engineers with indicators used to predict an eruption.

Students make a skydiver and parachute contraption to demonstrate how drag caused by air resistance slows the descent of skydivers as they travel back to Earth. Gravity pulls the skydiver toward the Earth, while the air trapped by the parachute provides an upward resisting force (drag) on the skydiver.

Students learn that wind and storms can form at the boundaries of interacting high and low pressure air masses. They learn the distinguishing features of the four main types of weather fronts (warm fronts, cold fronts, stationary fronts and occluded fronts) and how these fronts are depicted on a surface weather analysis, or weather map. Students also learn several different ways that engineers help with storm prediction, analysis and protection.

The focus of this unit is on meteorology concepts in relation to air pollution control and prevention. Students engage in hands-on activities to understand the properties and composition of air, relative humidity, barometric pressure, weather forecasting, and global climate regions.

For this maker challenge, students move through the engineering design process.  They investigate Python and Jupyter Notebook to analyze real astronomical images in order to calculate the interstellar distance to a star cluster across the Milky Way from our own Solar System. They learn how to write Python code that runs in a Jupyter Notebook so they can determine the brightness of stars in an astronomical image. Next, students complete the functions in the project to determine how far away a single star in the cluster is from Earth. This is a chance to try hands-on astronomical research techniques in the field of aperture photometry. The real astronomical image data will be directly manipulated and analyzed by code the students create. Groups compare their final images and results to answer questions about the astronomy of stars and stellar distances within the Milky Way. Students experience their discoveries the same way Harvard scientist Harlow Shapley first learned the true size and shape of the Milky Way.

Students learn the history of the waterwheel and common uses for water turbines today. They explore kinetic energy by creating their own experimental waterwheel from a two-liter plastic bottle. They investigate the transformations of energy involved in turning the blades of a hydro-turbine into work, and experiment with how weight affects the rotational rate of the waterwheel. Students also discuss and explore the characteristics of hydroelectric plants.

Students make sense of the design challenges engineers face that arise from earthquake phenomena. Students work as engineering teams to explore concepts of how engineers design and construct buildings to withstand earthquake damage by applying elements of the engineering design process by building their own model structures using toothpicks and marshmallows. The groups design, build, and test their model buildings and then determine how earthquake-proof their designs are by testing them on an earthquake simulator pan of Jell-O®.

Students begin to make sense of the phenomenon of electricity through learning about circuits. Students use the disciplinary core idea of using evidence to construct an explanation as they learn that charge movement through a circuit depends on the resistance and arrangement of the circuit components. Students also explore the disciplinary core ideas and crosscutting concepts of energy and energy transfer in the context of energy from a battery. In one associated hands-on activity, students build and investigate the characteristics of series circuits. In another activity, students design and build flashlights.
