Fizzy Nano Challenge
Source Institutions
This lesson focuses on how materials behave differently as their surface area increases.
Dust Catchers
Source Institutions
In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.
Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA
Source Institutions
Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.
Digestion
Source Institutions
In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.
Modeling Day and Night
Source Institutions
In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.
Fossilized Dinosaur Teeth Adaptations
Source Institutions
In this activity, learners use models of fossilized dinosaur teeth to understand how dinosaur teeth were used.
The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.
Geometry and Spatial Relations: Mirror, Mirror
Source Institutions
In this math lesson, learners use hinged mirrors to discover that regular polygons are composed of triangles tessellating around a center point.
Excavating and Mapping Under Water
Source Institutions
In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.
Where Will It Go?
Source Institutions
In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.
What Do Birds Do?
Source Institutions
This activity (located on page 3 of the PDF under GPS: Cave Swallows Activity) is a full inquiry investigation into bird behaviors.
From the Internet to Outer Space
Source Institutions
In this activity, learners will use Google Sky to observe features of the night sky and share their observations.
Geometry and Spatial Relations: Sidewalk Capers
Source Institutions
In this math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.
Measuring Your Breathing Frequency at Rest
Source Institutions
In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.
Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
Tops
Source Institutions
In this activity, learners discover that some things only stand up while they are spinning.
Stories in the Sky
Source Institutions
In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.
Battleships: Searching Algorithms
Source Institutions
This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
How Much Water is in that Cloud?
Source Institutions
In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.
