Learners make a "menu" of any plants in their lunch for Monday through Friday and draw the plants from their lunch.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

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.

Discover how the salt in soil affects plant growth with a few seeds, some cotton, and salt. In this hands-on activity, you will plant seeds in 2 different kinds of soil, containing more or less salt.

In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.

In this activity, learners plant seeds and watch them sprout and grow inside a CD case.

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

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

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.

In this activity, learners create a biosphere in a baggie.

In this activity, learners create a freshwater ecosystem in a large plastic bottle. Learners cut and prepare bottles, then fill with water, aquatic plants, snails and fish.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

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 two-part activity, learners compare and contrast a variety of life cycles to better understand different organisms and how they develop.

In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.

In this two-day activity (on pages 16-22), learners use a process like that of the Yoruba people of Nigeria to create an African symbol on cloth.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.
