DNA Extraction
Source Institutions
In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.
Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
Isopods
Source Institutions
In this outdoor activity, learners dig for and collect isopods (sometimes known as "roly-poly bugs" or "potato bugs" and other names).
Glove Gardens
Source Institutions
In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.
Growing Cooties
Source Institutions
In this health activity (located on page 4 of the PDF), learners will discover the importance of hand washing by observing mold growing on potatoes.
Water Clean-up
Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.
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.
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.
Do Your Own Dig
Source Institutions
In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.
DNA From an Onion
Source Institutions
In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.
Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.
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.
Insect Collection
Source Institutions
Learners use several types of insect sampling and collection equipment to make an insect collection. Learners can collect insects from their schoolyard or yard at home.
Pesticides and Eggshell Thinning
Source Institutions
This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.
Leaves: Extracting Pigments
Source Institutions
In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.
Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
Lima Bean Bacteria DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).
DNA the Easy Way
Source Institutions
This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.
Our Sense of Hearing
Source Institutions
In this activity, learners investigate the sense of hearing and plan and conduct their own experiments.
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.
