How Plants Grow
Source Institutions
In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.
Floating and Sinking Fruits and Veggies
Source Institutions
In this activity, learners will explore the density of an object in water. Learners will compare what happens to fruits and vegetables in regular and salt water.
A Swell Activity with Beans
Source Institutions
In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.
Salt, Soil and Seeds
Source Institutions
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.
Flower Power
Source Institutions
In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.
How Does Water Climb a Tree?
Source Institutions
In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.
TerrAqua Investigation Column: What is the Land-Water Connection?
Source Institutions
In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.
Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
Squishy Soil
Source Institutions
In this activity, learners will investigate the part of soil. Explore how clay, silt, and sand make up the dirt in your background. Activity includes step-by-step instructions and extension ideas.
Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.
Veggies with Vigor
Source Institutions
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.
Colors in Nature
Source Institutions
In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.
Photosynthesis and Transpiration
Source Institutions
In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.
Do Plants Need Sunlight?
Source Institutions
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.
