Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

In this laboratory activity, learners use a simple procedure to bait oomycetes from water and/ or soil and then examine these fungus-like organisms with the microscope to see how they look.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.
