Splish, Splash, I was Takin' a Bath!
In this lesson, students will explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they will investigate filtration and aeration processes as they are used for removing pollutants from water. Lastly, they will learn about the role of engineers in water treatment systems.

Tires and ecosystems
Tires are one of the worst things that can be thrown into a landfill. They take up a lot of room and they can collect rainwater that is a prime breeding ground for mosquitoes. Tires can be repurposed, or used for other purposes, such as tire swings and playground toys. They can also be recycled and used to make school gym floors and shoes.
Moss plant spore capsules
Mosses are the most well-known bryophytes and lack vascular tissue. Bryophytes reproduce by spore germination. The spores are released by the capsule atop the stalk-like structure growing from the plant. Because spores are dispersed by wind, bryophytes are found world-wide.
Early Movements in Science: Atoms
Early efforts made by scientists in India yielded atomic theories. These theories explained that everything in the world is made of atoms.
Visit Historic Natchez-Vicksburg in Mississippi

Fresh or Salty?
Between 70 and 75% of the Earth's surface is covered with water and there exists still more water in the atmosphere and underground in aquifers. In this lesson, students learn about water bodies on the planet Earth and their various uses and qualities. They will learn about several ways that engineers are working to maintain and conserve water sources. They will also think about their role in water conservation.
Growing and Graphing
Students visit a 2nd and a 4th grade class to measure the heights of older students using large building blocks as a non-standard unit of measure. They can also measure adults in the school community. Results are displayed in age-appropriate bar graphs (paper cut-outs of miniature building blocks glued on paper to form a bar graph) comparing the different age groups. The activities that comprise this lesson help students develop the concepts and vocabulary to describe, in a non-ambiguous way, ho
