In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.
