BACK TO SCHOOL
This resource includes everything you need to organize your pumpkin investigation day in first grade. The full-color posters introduce each hands-on activity with simple questions and visuals, while the matching recording sheets help your class collect data, write observations, and reflect on what they’ve learned. Each activity is structured to support scientific thinking—like measuring, observing, comparing, and using the five senses.
Each poster is designed for you to guide students through a hands-on investigation. Introduce the question, like “How many seeds are in our pumpkin?”, model the task, and facilitate the experiments. As students complete the activity, use the matching recording sheet and add their observations.
There’s no extra prep beyond printing the posters and copies—just add pumpkins and basic tools like scales, rulers, or bowls. The structure is built in, so you can focus on teaching science skills like measurement, comparison, and observation.
