Science Calendar Printable – A Full Year of Daily Science Questions for Kids

If you are looking for a simple, engaging way to make science part of everyday life, this science calendar printable is designed to do exactly that. Instead of long lessons or complicated experiments, this calendar uses short daily prompts that spark curiosity, observation, and discussion. It works beautifully as a wall calendar, morning work activity, homeschool science routine, or even as a science advent calendar that runs all year long.

Each month focuses on a different science theme, giving kids repeated exposure to key concepts over time. From life science and earth science to space, chemistry, and engineering, this printable helps children build knowledge naturally, one question at a time. It is a great way to encourage reading, critical thinking, and real-world connections using science they can see, touch, and talk about.

A Low-Prep Way to Teach Science All Year

Using a daily science calendar helps children see science as part of everyday life, not just something that happens in a textbook or on a screen. These short prompts encourage kids to slow down, notice the world around them, and think like scientists. Observation logs, predictions, and quick STEM challenges help build early scientific skills such as asking questions, making connections, and explaining ideas in their own words.

This format works across different ages and learning styles. Younger kids can answer orally or draw their ideas, while older children can write in more detail or extend the questions with research.

It is flexible enough to use at home or in the classroom, and it fits easily into busy schedules. Over the course of the year, kids build confidence with science language, concepts, and problem-solving without it ever feeling overwhelming.

Science Calendar Printable – What’s Included

This free science calendar printable includes a full year of daily science questions, with each month focused on a different theme. Every month features observation logs, trivia questions, predictions, vocabulary matches, true or false prompts, and quick STEM challenges. There is also space for writing or drawing responses, making it easy to use in a notebook or binder.

Below you will find a full breakdown of each month’s theme along with every daily question written out in text format.
