Investigating Questions Shake the tray of Jello to simulate secondary waves of an earthquake. Just for fun, place each structure on the Jello. Once the time is up, measure each structure using a ruler or tape measure. ![]() Also, remind them that they’re conducting an experiment, and it’s not safe to eat any part of the experiment. Once each student has a tentative design, allow them to build their structures within a fixed time (30-40 minutes should be sufficient). Remind them that they only have 20 marshmallows and toothpicks to create their structure. Have each student design a structure using marshmallows and toothpicks. Also, if a building were to fall down, a lot of people could get hurt. What could happen if a structure wasn’t strong enough? If structures are not strong enough, they could crack and crumble and cause a lot of damage to other surrounding buildings. Structures need to be made with materials that are strong enough to withstand wind, rain, really hot and cold temperatures and be as resilient as possible in the event of a natural disaster. Also, tall structures usually have a larger base and typically taper in shape as the building gets taller. What do these structures have in common? How are the shapes similar? How are they different? Stable structures often have cross bracings that form triangles in its design. Consider the Great Pyramids, CN Tower, and/or the Oriental Pearl Tower in Shanghai. Images of tall structures could be shown to motivate the discussion. This activity allows the students to design the tallest structure possible using a fixed amount of marshmallows and toothpicks. Tray of Jello (optional – can be prepared ahead of time keep chilled so it doesn’t melt).20 miniature marshmallows (fresh ones are best, structures become more stable as marshmallows dry out).Materials, Objects and Everyday Structures Materials Students will design and build a structure with a specific goal in mind. ![]()
