Chemical Weathering
Students measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.

Are All Asteroids' Surfaces the Same Age?
There are more than 600,000 asteroids in our solar system. Pupils analyze images of two asteroids in order to determine if they are the same age. They count craters for each asteroid and compare numbers.

Reopen: A Study of Five Closed Mines
Students analyze data to determine which of the fived closed mines would be beneficial to have reopen. They acquire knowledge of rocks and minerals in the area to give reasons why that mine should open again. Students gain knowledge in...
Curated OER
Sediment Tubes
Students observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.

Aerology- The Study of Mars
Students investigate various aspects of the planet Mars. They examine a core sample that is simulated to make observations. Then compare the known sample with one that is unknown and differentiate between the two. Students hypothesize...

How Old Is Mike?
Young scholars examine the absolute dating of fossils, they use a list of names and ages to determine the difference between relative age and absolute age. They explore the relative age and absolute age of people and of fossils.

Areology-The Study of Mars
Students examine core samples from Mars and discover what they can use it to tell the history of Mars. In this core sample lesson students create and analyze their own core samples then eat them at the end.

Volcano!-Thar She Blows!
Middle schoolers describe how volcanoes are formed. They name the types of boundaries where volcanoes occur. They utilize models to illustrate the occurence of volcanoes and earthquakes along plate boundaries. They compare and constrast...
Curated OER
Asteroids
Students examine a potential asteroid impact site. They describe evidence and theories for extinction events.

Formation of Rain
Students sequence the steps leading to the formation of rain, and design a model to represent these steps. This task assesses students' abilities to classify, generalize, infer, interpret and communicate data, and construct a pictorial...

Water Pollution
Young scholars study four samples of "rain water". They asked to determine the pH of the samples and then to neutralize them. Students are asked to predict any negative effects which might be associated with water having a low pH and...
