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

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

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

In this outdoor activity, learners design devices that will catch prey or gather plants.

In this outdoor activity/field trip, learners explore the concept of population density.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this four-part laboratory exercise, learners investigate properties of Tobacco mosaic virus (TMV) including (1) symptoms induced by the virus in susceptible plants at the macroscopic and microscopi

In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

In this online game, learners must purchase power plants for their city.

In this culinary activity, learners use multiple senses (sight, smell, touch, and taste!) to explore real seaweed samples.

In this hands-on botany activity, learners sprout vegetables in film canisters.

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

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.

Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.

This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing
