Original PromptCreate a lab experiment for Does chewing gum longer increase or decrease its stretchiness? with 2 different brands of gum using these steps: Step 1: Measure initial mass/length of 2 different gum brands.
Step 2: Chew Brand A for 1 minute, stretch over a meter stick, and record maximum stretch length (DV). Repeat for 3 trials.
Step 3: Repeat for Brand B under identical conditions.
The Great Gum Stretch Lab is a hands-on experimental activity designed for students to explore the physical properties of two different brands of gum. The primary goal is to measure and compare the maximum stretch length of each gum brand after chewing them for one minute. Through a structured procedure, students will gather data on the initial mass and length of the gum before chewing, predict which brand will stretch more, and then conduct the stretching part of the experiment. Data collection involves taking measurements across three trials for each brand to calculate average stretching lengths. Finally, students will analyze their findings using the Claim, Evidence, Reasoning (CER) approach to articulate their conclusions regarding which brand of gum exhibited the greatest stretch and why that might be the case. The lab encourages critical thinking and scientific inquiry into the properties and performance of consumer products.
