Hatch-a-Cyst
Source Institutions
What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.
Sand Paper Rankings
Source Institutions
In this activity (2nd activity on the page), learners explore the sensitivity of their sense of touch.
Subtracta's Dog
Source Institutions
In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.
Reebops
Source Institutions
In this genetics activity, learners create imaginary creatures known as "Reebops" to explore the relationships between genes and inherited traits.
Pupil to Pupil
Source Institutions
In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.
The Senses of "Unknown Creatures"
Source Institutions
In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.
Skewers and Garden Poles
Source Institutions
In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
Sock It To Me!
Source Institutions
In this activity (7th activity on the page), learners use their sense of touch to identify mystery objects hidden in socks.
Outbreak!: Investigating Epidemics
Source Institutions

Mystery of the Disappearing Cottonwoods
Source Institutions
Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
Animal Math Posters
Source Institutions
These math posters have questions written on them, such as: How fast can a cheetah run? or How long can a giant tortoise live? Post these around the room or leave them out for children to explore.
Plants Count
Source Institutions
In this activity, learners put on their naturalist hats and explore the world around them.
No-Slip Grip
Source Institutions
In this physical sciences activity, learners explore friction. Learners investigate the factors that affect the force required to move an object.
