Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.

In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.
