Students experience the engineering design process as they design, fabricate, test and redesign their own methods for encapsulation of a (hypothetical) new miracle drug. As if they are engineers, teams make large-size prototypes to test proof of concept. They use household materials (tape, paper towels, plastic wrap, weed-barrier fabric, glues, etc.) to attach a coating to a porous "shell" (a perforated plastic Wiffle® ball) containing the medicine (colored drink mix powder). The objective is to delay the drug release by a certain time and have a long release duration—patterned after the timed release requirements of many real-world pharmaceuticals that are released from a polymer shell via diffusion in the body. Guided by a worksheet, teams go through at least three design/test iterations, aiming to achieve a solution close to the target time release constraints.

Prior to reaching households, water is exposed to a variety of treatments designed to render it fit for human consumption and use. One of the first treatment steps is the removal of suspended solids using chemical additives called flocculants. In this activity, students learn about two commonly used flocculants and clean water collected from a local pond or river. They experiment with flocculant, stirring and pH variables.

Adding acidic ingredients is an important way to protect foods from dangerous …
Adding acidic ingredients is an important way to protect foods from dangerous toxins produced by organisms like C. botulinum, a microbe that is common and harmless in the environment but deadly when sealed with food in a jar. In the lab, testing the pH of a substance (how acidic or basic it is) provides important information for ensuring food safety. This module introduces users to proper sampling techniques when testing pH and explains how adjusting a food’s acidity can keep it safe from C. bot. Virtual Labs – Acidifying Salsa familiarizes the user with food science lab equipment and teaches standard techniques for sampling. The interactive animation guides the user through theory and practice of adjusting pH, so they will have familiarity with the equipment and procedures when encountered in a real lab.
Testing the pH of a substance (how acidic or basic it is) …
Testing the pH of a substance (how acidic or basic it is) is a basic lab test and provides a important piece of information for natural science investigations. In food science, the pH of a substance – how acidic or basic it is – is key to how it functions in food recipes. This module introduces users to the pH scale and its uses in food science. Then, users learn how to use the pH meter, and calibrate it by measuring solutions of standard value. Virtual Labs – the pH Scale & Meter Calibration familiarizes the user with food science lab equipment and teaches standard techniques for this specific procedure. The interactive animation guides the user through theory and practice of using the pH scale and pH measurement, so they will have familiarity with the equipment and procedures when encountered in a real lab.

Students measure the effectiveness of water filters in purifying contaminated water. They prepare test water by creating different concentrations of bleach (chlorine-contaminated) water. After passing the contaminated water through commercially available Brita® water filters designed to purify drinking water, students determine the chlorine concentration of the purified water using chlorine test strips and measure the adsorption of chlorine onto activated carbon over time. They graph and analyze their results to determine the effectiveness of the filters. The household active carbon filters used are one example of engineer-designed water purification systems.

Students learn about the underlying factors that can contribute to Plinian eruptions …
Students learn about the underlying factors that can contribute to Plinian eruptions (which eject large amounts of pumice, gas and volcanic ash, and can result in significant death and destruction in the surrounding environment), versus more gentle, effusive eruptions. Students explore two concepts related to the explosiveness of volcanic eruptions, viscosity and the rate of degassing, by modelling the concepts with the use of simple materials. They experiment with three fluids of varying viscosities, and explore the concept of degassing as it relates to eruptions through experimentation with carbonated beverage cans. Finally, students reflect on how the scientific concepts covered in the activity connect to useful engineering applications, such as community evacuation planning and implementation, and mapping of safe living zones near volcanoes. A PowerPoint® presentation and student worksheet are provided.

Students act as food science engineers as they explore and apply their understanding of cooling rate and specific heat capacity by completing two separate, but interconnected, tasks. In Part 1, student groups conduct an experiment to explore the cooling rate of a cup of hot chocolate. They collect and graph data to create a mathematical model that represents the cooling rate, and use an exponential decay regression to determine how long a person should wait to drink the cup of hot chocolate at an optimal temperature. In Part 2, students investigate the specific heat capacity of the hot chocolate. They determine how much energy is needed to heat the hot chocolate to an optimal temperature after it has cooled to room temperature. Two activity-guiding worksheets are included.

Students learn how common pop culture references (Harry Potter books) can relate to chemistry. While making and demonstrating their own low-intensity sparklers (muggle-versions of magic wands), students learn and come to appreciate the chemistry involved (reaction rates, Gibb's free energy, process chemistry and metallurgy). The fun part is that all wands are personalized and depend on how well students conduct the lab. Students end the activity with a class duel a face-off between wands of two different chemical compositions. This lab serves as a fun, engaging review for stoichiometry, thermodynamics, redox and kinetics, as well as advanced placement course review.
