Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
What's Hiding in the Air?: Acid Rain Activity
As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.
Composting
Source Institutions
In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.
Growing Plants: Track Their Growth
Source Institutions
In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.
Effect of Environment on Plant Growth
Source Institutions
The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.
Plant Tissue Culture: Classroom Activities in Plant Biotechnology
Source Institutions
In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le
Desert Water Keepers
Source Institutions
In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.
Flower Powder
Source Institutions
In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.
Easy PEAsy Seed Germination
Source Institutions
In this activity, learners determine the necessary conditions for pea seed germination.
Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
The Water (Hydrologic) Cycle: Transpiration
Source Institutions
In this lab, learners grow broad bean (also called fava bean) plants in three EarthBoxes for a few weeks before exposing one to wind (using a fan), another to heat (using a lamp), and the third to not
Living Clocks
Source Institutions
In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
Using a Sundial
Source Institutions
In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.
Composting: A Scientific Investigation
Source Institutions
In this activity, learners conduct a scientific investigation involving decomposition and discover that the life cycle of trash is affected by its organic or inorganic nature.
Irrigation Ideas
Source Institutions
In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.
The Decayed Pumpkin
Source Institutions
In this "Sid the Science Kid" activity from Episode 106: My Mushy Banana, learners explore the effects of decay by comparing and contrasting something (an old pumpkin) that's decayed with the same thi
Powdery Mildew Fungi: Classification and Ecology
Source Institutions
In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery
Creating a Soil Map
Source Institutions
In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.
What Does Life Need to Live?
Source Institutions
In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
