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.
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.
How Quick Are Your Responses?
Source Institutions
In this activity (on page 134 of the PDF), learners explore reaction time.
It's a Gas, Man
Source Institutions
In this activity, learners discover if carbon dioxide has an effect on temperature.
Proportionality: The X-Plane Generation
Source Institutions
In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.
Pedal Power
Source Institutions
In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.
Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.
My Angle on Cooling: Effects of Distance and Inclination
Source Institutions
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
Dogs and More Dogs
Source Institutions
In this activity, learners play an evolution card game to see how selective pressures can affect an organism's evolution.
Supporting Structures
Source Institutions
In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.
Heart and Lungs
Source Institutions
In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.
Modeling the Night Sky
Source Institutions
In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.
Wolf Limiting Factors
Source Institutions
In this activity, learners simulate a wolf and its habitat and observe what happens when the limiting factors change over time.
Out of Sight: Remote Vehicle Activity
Source Institutions
In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.
Our Sense of Sight: How We Perceive Movement, Depth and Illusions
Source Institutions
In this activity, learners investigate visual perception as well as plan and conduct their own experiments.
Modeling an HIV Particle
Source Institutions
This activity helps learners visualize the Human Immunodeficiency Virus (HIV) by constructing three-dimensional HIV particle models from paper.
Shadow Play
Source Institutions
In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.
Measurement: It Takes Ten
Source Institutions
In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.
Looking Through the Algebraic Lens
Source Institutions
In this two-part math lesson, learners investigate problems that foster algebraic thinking across content strands. In the first part, learners explore even and odd numbers linked to quilts.
Pet Parasite Detective
Source Institutions
This activity (on pages 19-25) is about fleas and ticks, which are common pet parasites.
