Tops
Source Institutions
In this activity, learners discover that some things only stand up while they are spinning.
Changing the Density of a Liquid: Adding Salt
Source Institutions
Learners see that a carrot slice sinks in fresh water and floats in saltwater.
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.
Invisible Ink Demonstration
Source Institutions
In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.
Density: Make a golf ball float!
Source Institutions
In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.
Separation Anxiety
Source Institutions
In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.
Exploring Products: Nano Sand
Source Institutions
In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.
Charge Challenge
Source Institutions
In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.
Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.
Making a One-Second Timer
Source Institutions
This lab activity has learners create a pendulum with a one-second period.
M&M's in Different Temperatures
Source Institutions
Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.
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.
Boomerang
Source Institutions
Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.
Matraca
Source Institutions
In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.
Watching Crystals Grow
Source Institutions
Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.
Formation of a Precipitate
Source Institutions
Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.
Message in a Neuron
Source Institutions
In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.
Atoms and Matter (3-6)
Source Institutions
In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.
Changing the Density of an Object: Changing Shape
Source Institutions
Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.
