Leaf Me Alone
Source Institutions
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.
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.
Find Out How Plants Use Water
Source Institutions
In this activity, learners investigate how plants use water. By making the flowers change color, learners see how water moves up the stem to the leaves and the flowers.
Easy PEAsy Seed Germination
Source Institutions
In this activity, learners determine the necessary conditions for pea seed germination.
CD Greenhouse
Source Institutions
In this activity, learners plant seeds and watch them sprout and grow inside a CD case.
Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
Soil Density
Source Institutions
In this activity, learners will test soil content using their sample, some water and a container that seals.
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.
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.
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.
Make a Friend from Soil and Seeds
Source Institutions
Learners assemble a figure from a nylon stocking or sock stuffed with soil and seeds. The ends of the nylons inside the jar absorb water, which feeds the grass seeds.
Many Seeds: Estimating Hidden Seeds
Source Institutions
In this activity, learners will estimate how many seeds are in a fruit or vegetable, then count to find out. The result: mix estimation with healthy eating.
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.
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.
The Self-Watering Terrarium
Source Institutions
In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.
BioBlitz
Source Institutions
In this activity (on page 2 of the PDF under GPS: Biodiversity Activity), learners will pair up and take a notebook outdoors to a selected location to observe and record a list of living things that t
Color-Changing Carnations
Source Institutions
Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.
Partners in Pollination
Source Institutions
In this activity, learners identify the reproductive parts of plants and the animal (bee) structures involved in pollination.
Tree-mendous Plots
Source Institutions
In this math lesson, learners record and graph plant growth and interpret data. Learners plant seeds, and once the seeds sprout, record the change in height of the plants for several days.
Grow a Garden in a Glove
Source Institutions
Learners use a transparent plastic glove as a container to grow seeds. A different kind of seed can be planted in each finger.
