Another A+ lesson on the impact of climate change comes to you from the National Earth Science Teachers Association. In this installment, learners model the stratification of water in lakes due to temperature differences. The lab also...

Field study groups collect samples of stream water and identify the macroinvertebrates found. Using their data, they calculate a water quality index to rate the health of the stream. They graph their data and discuss the value of a water...

Young scholars visit a local creek or stream. They collect water samples from the creek and observe and sort the "water critters" they find in the sample, observing smaller organisms under a microscope if necessary. They identify each...

Students explore what a food web is. In this science lesson, students examine how nutrients and other pollutants enter a lake and play a food web game whereby students pretend they are either zooplankton, planktivore,...

A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

Students investigate the presence of specific organisms in a freshwater habitat to determine the quality of that habitat. They conduct a field study and distinguish and classify organisms found during the field study.

Fifth graders explore osmosis as they watch organisms divide.  In this organism activity, 5th graders use potatoes to experiment with the effects of salty water in the body.  Students discuss what osmosis is and record what...

Eighth graders identify the Great Lakes, and describe the habitat of life of a loon. They are able to point to and explain one of the major river systems that enters the Great Lakes with a focus on the Clinton River and the food webs...

Students make a water sampler and use proper techniques to collect water.They write a essay explaining the inter-relationship of factors such as temperature, pH, dissolved oxygen, nitrates, and phosphates in a lake that might cause a...

Compare and contrast the characteristics of fresh and salt water marshes. After exploring the typical plants and animals found in each marsh type, participants use a set of flash cards to sort into fresh and salt water marsh life. Their...

Students use a simple method to collect living microorganisms from natural and/or artificial environments and develop skills in microscopy, observation, drawing, speculation, hypothesizing, oral presentation, and raising questions.

Students examine the early development of zebrafish as a model for embryo development in humans. They observe various stages of zebrafish reproduction from sperm and eggs to fertilized eggs and hatchlings.

Students complete a KWL chart on what they comprehend about water. They complete a water activity determining how much usable water is available, and they determine the water usage in their households. Students take notes on water and...

Learners are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier probes...

Pupils listen to a story about seashells. They discuss shelled animals. Learners describe the function of seashell. Pupils relate the function of a seashell to their own dwelling. They differentiate between shelled animals that make...

Students are asked to respond to questions such as:" Have there been surveys of the area to inventory the species?" (For example, for a wetland area, do they know what amphibians live there and how abundant they are?) Are there any...
