Dust Catchers
Source Institutions
In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.
Water Holes to Mini-Ponds
Source Institutions
Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.
Is That DNA in My Food?
Source Institutions
In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.
Bee Talk
Source Institutions
In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.
Wheat Evolution: Sedimentation Testing
Source Institutions
In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.
Straining Out the Dirt
Learners take on the role of environmental engineers as they design water filters.
Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.
Currently Working: Testing Conductivity
Source Institutions
Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.
Planaria Regeneration
Source Institutions
In this experiment with planaria (a type of flatworm), learners will investigate the capability of different body sections to regenerate.
Animal & Plant Cell Slides
Source Institutions
In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.
Fragile Waters
Source Institutions
In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.
Mold Growth
Source Institutions
In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.
Plant Power
Source Institutions
In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.
Pet Handedness
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Pet Handedness) is a full inquiry investigation into whether pets show a preference for the left or right paw, or “handedness” like people.
Aye-Aye
Source Institutions
This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.
Odors Aloft
Source Institutions
Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.
Isolation of DNA from Onion
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.
There’s No Place Like Home!
Source Institutions
In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).
Breathing Room
Source Institutions
In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.
Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.
