Nano Ice Cream
Source Institutions
In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.
Rice Handle
Source Institutions
In this physics activity, learners attempt to lift a jar full of rice using only a spoon.
Instant Ice Cream
Source Institutions
In this activity, learners make instant ice cream without using a freezer.
Checking For Starch
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.
DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.
Making a Battery from a Potato
Source Institutions
In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.
Testing Falling Peanut Butter Sandwich Myth
Source Institutions
In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi
Mixtures and Solutions
Source Institutions
This activity was designed for blind learners, but all types of learners can use it to investigate heterogeneous and homogeneous mixtures and solutions, identify the differences, and explore the conce
Mystery Writing: Write and develop a secret message
Source Institutions
Learners write an invisible message using lemon juice on a piece of paper. They then develop the message by soaking the paper in a dilute iodine solution.
Making An Impact!
Source Institutions
In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
Take an Egg for a Spin
Source Institutions
This is an activity about friction as well as kinetic and potential energy.
Powder Particulars
Source Institutions
In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.
Candy Chemistry
Source Institutions
In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.
Cabbage Patch Chemistry
Source Institutions
In this chemistry activity, learners will learn how to make their own pH indicator using cabbage leaves, and then test common household items with their homemade indicator.
Sticky Situation
Source Institutions
In this activity, learners separate the protein from milk and and use it to make their own glue.
