Modeling Tidal Action
Source Institutions
In this activity (Lesson 1), learners work in groups to create tide simulations.
Disappearing Crystals
Source Institutions
Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.
Shower Estimation
Source Institutions
In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.
The China Hammer Mystery
Source Institutions
In this activity, learners are asked to examine the differences between two materials in a pair.
Can Energy be Created or Destroyed?
Source Institutions
In this activity, learners explore conservation of energy by experimenting with a solar cell light device.
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.
Curious Contraptions
Source Institutions
In this engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.
Busted by Biology
Source Institutions
In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.
Potion Commotion
Source Institutions
In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.
Operation Espionage
Source Institutions
In this activity, learners create and reveal secret messages written with invisible ink! The invisible ink is actually a baking soda solution, and the magical revealing liquid is fruit juice.
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.
Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.
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.
Biochemistry Happens Inside of You!
Source Institutions
In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.
A Matter of Splatter
Source Institutions
In this math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.
Mirror Image
Source Institutions
In this activity, learners investigate procedural memory.
Breaking Point
Source Institutions
In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.
Where Does the Wind Blow?
Source Institutions
In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.
What's the Angle?
Source Institutions
This activity helps learners understand how the angle of the Sun affects temperatures around the globe.
