Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
How can Clouds Help Keep the Air Warmer?
Source Institutions
In this activity, learners explore how air warms when it condenses water vapor or makes clouds.
Hot Stuff!: Testing for Carbon Dioxide from Our Own Breath
Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.
Chemical Reactions in Your Mouth
Source Institutions
In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.
Half Full or Half Empty
Source Institutions
In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.
Reaction Time
Source Institutions
In this activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.
The Nose Knows
Source Institutions
In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.
DNA Extraction: Look at your genes!
Source Institutions
Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.
Why Are Two Eyes Better Than One?
Source Institutions
In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.
Auditory Acuity
Source Institutions
This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.
Iron in Cereal: Find iron in your food!
Source Institutions
Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.
Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.
Catch the (Sound) Wave!
Source Institutions
See and hear how sound waves travel through different types of materials. Extend the experiment online and learn how you can "see" with sound waves using ultrasound.
Drop IT!: Depth Perception
Source Institutions
These two activities (4th on the page) demonstrate the importance of two eyes in judging depth.
Release the Grease!
Source Institutions
In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.
Ziploc Digestion Simulator
Source Institutions
In this biology activity, learners recreate the process of digestion in a zip lock bag. A bit of soda pop added to some crumbled crackers approximates how acids in the stomach dissolve food.
Breaking Up with Combustion
Source Institutions
This activity teaches combustion as the interaction of a fuel source and oxygen.
