pH is a very important concept in chemistry. During this lesson, students learn about pH and how it affects us and the world around us. They will then use a universal indicator and concentrated acids and bases to create a rainbow of colored solutions. Before the solutions are discarded, the students will have to figure out how to neutralize each solution.
CSI in a Wheat Field
Chemistry is everywhere, even in the soil beneath our feet. During this hands-on activity, students will learn about the importance of Earth's most valuable resource, soil, and its chemical properties. Students will then assume the role of a crime scene investigator and use a soil test kit to look at the chemical properties of various soil samples to determine if fictional suspects were at the scene of a crime.
DNA is the blueprint for life and almost every living organism on Earth contains a unique sequence of nucleotide bases. During this lesson, students will learn about the basics of DNA sequences and base pairing by constructing a bracelet of DNA sequence from organisms including humans, chimpanzees, butterflies, carnivorous plants or flesh-eating bacteria.
How are living things named and classified? During this exercise, students learn about how organisms are named and classified. They then learn about leaf anatomy and use a dichotomous key to identify unknown leaf samples.
Molecules Matter! Photosynthesis
How do elements form compounds and what do these compounds look like? Students will learn about how elements bond to form compounds. They will also learn about the most important chemical reaction on Earth, photosynthesis, and will construct 3-D models of the compounds of photosynthesis using spice drops and toothpicks.
Strawberry DNA Extraction
DNA is the blueprint for life. Almost every living thing on Earth contains DNA. In this experiment, students learn about DNA and extract it from a strawberry using common household chemicals.
The Crayon Rock Cycle
Weathering and erosion of rock is a very important part of soil formation, one of Earth's most important geological processes. But, how are rocks formed? This lesson teaches students about the rock cycle by using crayons to model the formation of each of the different types of rock: sedimentary, metamorphic and igneous.
