Exploring Tools: Special Microscopes
Source Institutions
In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

Luminol Test
Source Institutions
Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

Acid Rain
Source Institutions
In this chemistry demonstration, acid rain is simulated in a petri dish.

Rock Bottoms
Source Institutions
Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.
Diffraction Between Wax Blocks
Source Institutions
In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

Burning Issues
Source Institutions
Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

What's Your Blood Type?
Source Institutions
In this activity, learners perform a simulated blood test procedure.

It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.
Interference in a Ripple Tank
Source Institutions
In this optics activity, learners explore interference by adding wax blocks to a ripple tank.

Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

Exploring Earth: Temperature Mapping
Source Institutions
This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
