Wear-Away and Wandering Water

When you water a plant, it miraculously grows. What is found under the soil where you put the water and how does that help the plant? Throughout the five-day activity, learn about the water cycle, the parts of a plant, and how gardens...

Trees are everywhere! Yet what do these majestic organisms do for their ecosystem, and why do some have leaves and some have needles? During a five-day activity, young scientists investigate trees by analyzing the water cycle,...

How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

A drop of dew holds a sphere shape even when sitting on a seat thanks to the surface tension of water. Learners observe the phenomena of surface tension in water. Through demonstrations, hands-on activities, and discussions they explore...

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity allows...

Students devlop a model, which they illustrate a water table and allow for the discussion of common terms and illustrate what those terms mean. They comprehend that a flow rates, removal of contaminants, and the amount of water stored...

Upper elementary learners discover the difference between weathering and erosion and the effect these forces have on the environment. Pupils create water and wind erosion models to observe and record data. Then towards the end of the...

Here's an engaging unit on erosion for your upper elementary and middle school scientists. Five hands-on activities demonstrate the processes and effects of erosion by wind, chemical reaction, temperature, water, and glacial action....
