Pulse of Life: Measure Your Pulse
Source Institutions
In this activity, learners take their own pulse and explore how heart rate is affected by various activities.
Clam Hooping
Source Institutions
In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.
Colour by Numbers: Image Representation
Source Institutions
This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.
Designer Seeds
Source Institutions
In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.
Chilean Sea Bass: Off the Menu
Source Institutions
In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.
Making Sense of Sensors
Source Institutions
In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.
Equatorial Sundial
Source Institutions
In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.
Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.
Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.
Earth Walk
Source Institutions
In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook
Egg Bungee
Source Institutions
Learners attach an egg to a rubber-band bungee cord and drop the egg.
Edible Glass
Source Institutions
In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.
Mosquito Life Cycle
Source Institutions
In this activity, learners build a plastic emergence chamber (or use purchased "mini mosquito breeder") to observe and analyze the mosquito life cycle.
Tasty Buds
Source Institutions
In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.
Seas in Motion
Source Institutions
In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.
Temperature vs. Height: Soda Geyser Series #6
Source Institutions
In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.
Clipbirds
Source Institutions
In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.
Biodiversity and Evolutionary Trees
Source Institutions
In this interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.
Getting There!: Navigation and Trajectory
Source Institutions
In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.
Vestibular-Ocular Reflex
Source Institutions
In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.
