Students see and learn how crystallization and inhibition occur by making sugar crystals with and without additives in a supersaturation solution, testing to see how the additives may alter crystallization, such as by improving crystal growth by more or larger crystals. After three days, students analyze the differences between the control crystals and those grown with additives, researching and attempting to deduce why certain additives blocked crystallization, showed no change or improved growth. Students relate what they learn from the rock candy experimentation to engineering drug researchers who design medicines for targeted purposes in the human body.

Students engineer surfaces to control and modify friction and grip as they design and build a tabletop game that uses sliding friction as the main component of its mechanics. Students first observe surface roughness on a variety of surface materials using a digital microscope and explore how engineers use surface modifications to manage friction. They then investigate and compare the friction and grip on multiple surface materials using an inclined plane. Applying the concepts of surface roughness and surface modification, students work as engineering teams to create a tabletop game that uses sliding friction as a main game mechanic. Students go through the steps of the engineering design process, from ideation to prototype development. Students test their own games to balance relevant parameters (surface roughness, speed, board design, game rules, etc.) to improve their prototypes. Students review the prototypes of their peers and offer feedback for further improvements.

Students learn about coordinate systems in general by considering questions concerning what it is that the systems are expected do, and who decided how they look. They attempt to make their own coordinate systems using a common area across all groups and compete to see who can make the best one. Then they analyze why it is that some systems work better than others and consider what those observations mean for evaluating and choosing geographic coordinate systems commonly available today.

Students combine art, gaming culture and engineering by fabricating light-up patches to increase youngsters’ visibility at night. The open-ended project is presented as a hypothetical design challenge: Students are engineers who have been asked by a group of parents whose children go out Pokémon hunting at night to create glowing patches that they adhere to clothing or backpacks to help vehicle drivers see the kids in the dark. Student pairs create Pokémon character stencil designs cut from iron-on fabric patches, adding transparent layers for color. Placed over an EL (electroluminescent) panel that is connected to a battery pack, the stencils create glowing designs. Each team creates a circuit, which includes lengthening the EL panel wiring to make it easier to wear. Then they sew/adhere the patches onto hoodies, messenger bags, hats, pockets or other applications they dream up. The project concludes with team presentations as if to an audience of project clients. Keep the project simple by hand cutting and ironing/sewing, or use cutting machines, laser cutters and sewing machines, if available.

Students conduct a research-based activity to explore, graph, and evaluate the speed of slime, or how far and at what rate slime stretches. During the activity, the students review the major concepts of graphing speed by stretching gum or silly putty. After reviewing how to create and read speed on a graph, students create a “super-stretchy” slime sample. Students conduct tensile tests to determine the fastest speed the slime can stretch without snapping. Students analyze the slime stretching data by compiling it in a speed graph using Google Sheets or Microsoft Excel. Lastly, students communicate their findings through a poster presentation

Using spaghetti and marshmallows, students experiment with different structures to determine which ones are able to handle the greatest amount of load. Their experiments help them to further understand the effects that compression and tension forces have with respect to the strength of structures. Spaghetti cannot hold much tension or compression; therefore, it breaks very easily. Marshmallows handle compression well, but do not hold up to tension.

One way to conserve energy in a building is to use adequate insulation to help keep hot or cool air inside or outside of the structure. Inefficient heating and cooling of buildings is a leading residential and industrial source of wasteful energy use. In this activity, student groups conduct a scientific experiment to help an engineering team determine which type of insulation conserves the most energy—a comparison of newspaper, wool, aluminum foil and thin plastic. They learn about different kinds of insulation materials and that insulation prevents the transfer of heat, electricity or sound. Student teams collect data and make calculations, then compare and discuss their results. A student worksheet is provided.

Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs, students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple's offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the pairs in the class. In particular, they look for cases in which parents and offspring share the exact same genotype and/or phenotype, and consider how the results would differ if they repeated the simulation using more than four traits.

Posed with a paradigmatic engineering problem, students consider and explore mathematical algorithms and/or geometric concepts to devise possible solutions. The problem: How should a robotic vacuum move in order to best clean a floor of unknown shape and dimensions? They grapple with what could be a complex problem by brainstorming ideas, presenting the best idea for a solution and analyzing all presented solutions, and then are introduced to an elegant solution. Rather than elaborately calculating the most efficient route and keeping track of which tiles the robot has visited, a random number generator determines which direction the robot will take when it hits a barrier. Students are able to visually confirm how an unfamiliar programming concept (a random number generator) can make for a simple and efficient program that causes an EV3 robot (that is suitably equipped) to clean a bare floor. Then students think of other uses for random numbers.
