Observing Different Microbes
Source Institutions
In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.
How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
Liesegang Rings
Source Institutions
This display shows slow chemical reactions in colorful crystal formations known as Liesegang Rings. These reactions are similar to those forming the rings in agates.
Volcanic Material Catapult Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.
Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.
What is in the Water?
Source Institutions
In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.
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
Crime Scene Investigation (CSI) with Powdery Mildew Fungi
Source Institutions
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.
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.
Lilliputian Landscaping
Source Institutions
In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.
Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
We all Scream for Ice Cream
Source Institutions
In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
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).
Air Cannon
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end
Solar Water Heater
Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.
Plastics the Second Time Around
Source Institutions
In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.
Illuminating Luminescence
Source Institutions
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
Investigating and Using Biomass Gases
Source Institutions
In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.
Determining the Amount of Transpiration from a Schoolyard Tree
Source Institutions
In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.
