Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
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.
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.
Planting with Precision
Source Institutions
In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.
Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.
Lighting Up Celery Stalks
Source Institutions
In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla
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.
The Carbon Cycle and its Role in Climate Change: Activity 1
Source Institutions
In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.
Irrigation Ideas
Source Institutions
In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.
The Carbon Cycle and its Role in Climate Change: Activity 2
Source Institutions
In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause
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).
Breaking Point
Source Institutions
In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.
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.
Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
The Water Cycle
Source Institutions
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.
The Colors of Flowers
Source Institutions
In this activity, learners perform an experiment to find out what determines a flower's color.
Photosynthetic Pictures Are Worth More Than a Thousand Words
Source Institutions
This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.
From the Ground Up
Source Institutions
In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.
