Clay Bridges
Source Institutions
In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.
Sink It
Source Institutions
Learners classify a variety of objects by their characteristics. They then design an experiment to determine which objects float or sink in water and add this characteristic to their classification.
Nutritional Challenges
Source Institutions
In this nutrition activity (page 26 of PDF), learners consider the nutritional needs of people with specific dietary requirements, such as athletes, persons with diabetes and vegetarians, and create a
Shrinkers: Cook up some plastic!
Source Institutions
In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.
Vestibular-Ocular Reflex
Source Institutions
In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.
Make Pooter
Source Institutions
In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.
Choose Your Ooze
Source Institutions
During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.
Miscibility
Source Institutions
Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.
What Do You Know About Microbes?
Source Institutions
This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.
Plankton Races
Source Institutions
In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.
Design and Build a Better Candy Bag
Source Institutions
In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.
What's the Buzz?
Source Institutions
In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.
The Web of Life
Source Institutions
In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.
Nice and Nasty
Source Institutions
In this math game, learners throw dice and place the numbers in one of four boxes. Learners repeat this three more times and the learner with the largest four digit numbers is the winner.
Outrageous Ooze: Is It a Liquid or a Solid?
Source Institutions
This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.
Tri, Tri Again
Source Institutions
Learners estimate how many small triangles will fill a larger shape. Then they use a triangle stamp (or stencil made from a file folder) to fill the larger shape with triangles.
COSI Quicksand
Source Institutions
In this chemistry experiment, learners get to make a very bizarre substance using corn starch and water. Is it a solid? Is it a liquid? Or is it a different kind of substance entirely?
Give Me a Brake
Source Institutions
In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.
Multitasking Mania
Source Institutions
In this activity, learners conduct scientific research on multitasking. Learners determine if multitasking with media while doing homework affects their ability to successfully complete the homework.
Pollution in Our Watershed
Source Institutions
By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from
