How does Temperature Affect Time in the Pupa Stage?

What effects do temperature and carbon dioxide levels have on the zooplankton of Antarctica? This concluding lesson plan in a short unit on climate change and the ocean helps environmental scientists answer these questions. After...

Students conduct an experiment to determine what type of clothing would be most suitable for outdoor activities. They determine the temperature changes of the skin under various wet clothing materials and graph the temperature changes. ...

Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Learners explore the exponential growth and decay of microbial populations in relation to the organism tolerance ranges in their environment, They observe the impact of changing variables which can affect microbial populations.

High school or college horticulturists will appreciate this PowerPoint on seed-propagation. It walks them through the science behind seed production and germination as well as the requirements for growing plants from this stage....

An extensive investigation of the Earth's climate changes awaits your environmental science classes. This top-notch presentation begins by looking at the history of Earth's climate and then predicts the impact on each major terrestrial...

Learners relate heart rate and development to environmental conditions through experiment. In cooperative groups, students record the heart rate in developing zebra fish. Groups create a standard curve to predict the temperature at...

Students listen to a lecture on four factors that influence microbial growth and they discuss how to test the optimal growth requirements of a designated bacterium. They design and carry out laboratory investigations to test growth of...

A three-page introduction to reproduction in amphibians can be found at this site. Read about the various methods of reproduction, and what happens after the eggs are laid. There is also a section that shows the growth/development stages...

What happens in the Arctic doesn't always stay in the Arctic. Follow along with this short video as it investigates how small changes in the temperature of Arctic regions can have dramatic effects on the global climate through a series...
