Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.

Making Sense of Sensors
Source Institutions
In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

Measure the Pressure II: The "Dry" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.
Making Rivers
Source Institutions
In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

Percentage of Oxygen in the Air
Source Institutions
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

Twirling in the Breeze
Source Institutions
In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

Atmosphere Composition Model
Source Institutions
In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
Investigating Density Currents
Source Institutions
In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

Measure the Pressure: The "Wet" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.

We all Scream for Ice Cream
Source Institutions
In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

Water, Water Everywhere
Source Institutions
In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea
