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.
The Boxes Go Mobile
Source Institutions
Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.
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.
Physics Tug of War
Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.
Measurement: How Many Noses Are in Your Arm?
Source Institutions
In this math lesson, learners apply the concepts of ratio and proportion to determine the length of the Statue of Liberty's torch-bearing arm.
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.
Tops
Source Institutions
In this activity, learners discover that some things only stand up while they are spinning.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Chromatography Can Separate!
Source Institutions
In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.
The Rumblin' Road: Determining distance to a Thunderstorm
Source Institutions
In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.
Box Ecology
Source Institutions
This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.
Hold a Hill
Source Institutions
In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.
Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.
Planaria Regeneration
Source Institutions
In this experiment with planaria (a type of flatworm), learners will investigate the capability of different body sections to regenerate.
Sizing Up Hail
Source Institutions
In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.
Comparing the Density of an Object to the Density of Water
Source Institutions
Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.
Don't Crack Humpty
Source Institutions
Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.
Incredible Shrinking Shapes
Source Institutions
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.
