Students examine the animals that live in trees. They identify their sounds, footprints and droppings. They draw pictures of the animals as well.

Students conduct an experiment to investigate the rate of microbial growth at different temperatures. Students predict what will happen to the food at various temperature and test their hypotheses. Students describe the differences in...

Students discuss the importance of reproduction of cells. They identify and describe the stages of Mitosis. They discover what happens to chromosomes and DNA during reproduction.

Students identify Gram positive and Gram negative bacteria using staining techniques. Students research importance of identification of bacterial types in diagnosing bacterial diseases.

Sixth graders conduct a variety of assessments at a local stream to determine if it is a suitable habitat for salmon. They measure temperature, tubidity, dissolved oxygen, pH levels, bacteria and nutrients. In this unit, 6th graders work...

Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...

Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.

Students observ the cooling and warming of room temperature, hot, and ice cold cans of water by measuring the change in temperature over time. They then attempt to develop explanations for the observations made and apply their findings...

Learners role several balls of different weights down a ramp and into a paper cup and record how far each ball made the paper cup move. They then answer questions that help them analyze their results and reinforce the idea that energy...

Pupils investigate the motion of a swinging pendulum. They experiment with a pendulum to find out why it might swing at different speeds at different times.

Learners observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.

Students observe the motion of both a pendulum and a spring pendulum . They then explain the differences and the similarities between the two types of motions.

Students compare the price and quality of different kinds of plastic kitchen wraps and then rank them from best to worst. They take into account how well it comes out of the roll, if it seals well, it is tangles, how much weight it...

Learners examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...

Students design a chart to use to record the weather for five days. They then build an anemometer to record wind speed and discover why they are used for this purpose.

Young scholars listen to Chapter I, Chapter II, Chapter III, and Chapter IV of "The Forgetful Pony". They observe different stages of development of mealworms. The student sequences pictures to show the life cycle and draws the...

Students create a mural showing ocean zones and the diversity of ocean life. They use reference books to create a list of plants and animals that would live in each zone.

Students investigate the variety and amount of particulate matter in the air. They locate the general sources of pollution for a specific area and develop some suggestions for improving air quality.

Tenth graders study the diversity of life in the world. They classify and sketch organisms into the 6 kingdoms.

In this comprehensive interactive tutorial you will learn about the parts of a microscope and how some types of microscopes are better than others for certain types of evidence analysis within the field of Forensic Science. A...

This is a site full of information about various microscopes and the objects and processes scientists study with them. Includes timelines and interactive simulations.

At this resource you'll find everything from a mosquito head to a fly foot, from a dentist's drill to toilet paper! These and just about everything in between as seen through a scanning electron microscope.

This site from Georgia State University Physics Department provides a discussion of how light refracts through the lenses of a microscope. Demonstrates the parts of a microscope and includes an interactive form in which the magnifying...
