Plant Pigment Chemistry

Students use chromatography to separate plant pigments collected from a fictitious crime scene and suspects. They compare the Rf values of the plant pigments to determine whether the plant pigments found on any of the suspects match the...

Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

Pigmentation of leaves is important in plant processes. Scholars use chromatography to create a better picture of the pigmentation in an assortment of leaves. They share their results to make comparisons between different plant species.

Thin-layer and gas-liquid chromatography are introduced in an intelligible presentation. Paper chromatography is also listed as another type of chromatography, but it is not explained. If you are particular about appearances, there are...

Scientists found fossils of plants more than 420 million years old—but plants existed for up to 100 million years prior to these fossils. Learn about the importance of plants to the entire planet. Viewing a presentation helps scholars...

Discover the scientific explanation of fall leaves! The lesson narrator describes the role of chlorophyll, glucose, and weather in the process of the color-changing process. He adds an overview of carotenoids and flavonoids to explain...

Discover the chemistry behind the color change in leaves. The lesson narrator describes how trees must recycle nutrients in the leaves before they fall off for the winter. The video breaks down the process and highlights the chemistry of...

Are all reds the same? Find out in this science fair project. Investigate if the pigments in one type of red flower are different from those in another type of red flower. Flowers contain an assortment of amazing chemicals that produce...

Young scholars use leaves to make model of a carbonized plant and classify leaves by shape and margin type.

Beginning botanists learn basic plant structure by viewing this presentation. It is somewhat lifeless because there are no photos, so you will want to display actual plants as you work through the slides. The information, however, is...
