Students define the term solution. They explain conservation of energy and energy transfer as it relate to how the milk solution became ice cream. Students are able to explain freezing point depression.

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

Young scholars explain the complexities of environmental decisions, rather than to recreate the actual circumstances and outcome of the original case. They simulate a real environmental case a regarding the Pine Barrens of Long Island, NY.

Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific...

Discover the coldest animals in the world with a lesson about the Arctic habitat. Kids use a glossary and information sheet about animals found in the Arctic Circle to complete several activities, including tracking the lemming...

Explore the water cycle with a hands-on earth science activity that prompts pupils to measure the amount of water normally transpired by plants. After they describe the flow of the water cycle and provide examples of how human...

Your science class reads a silly story in which a mad scientist makes absurd conclusions about an experiment that he conducted. One at a time, he cuts off a frog's leg and commands it to jump. With three, two, and one leg, the frog...

Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...

Students explore the scientific method. In this science lesson, students create and conduct a science investigation for the science fair.

In this planning frame learning exercise, students use the template to make notes and organize ideas related to a science procedure they plan to execute.

In this geology instructional activity, students conduct several experiments by using granite rock. The experiments include heating and cooling the rock and shaking the rock in a bottle to cause abrasion. Students answer three short...

Students develop a device that can measure pH. In this science lesson plan, students test different solutions and determine whether they are acidic or basic. They write a complete lab report about the process.

Students extract DNA from their own hair roots. They run an electrophoresis gel to examine patterns of their DNA along with standard DNA. The experiment is based on a crime scene scenario.

Elementary schoolers take part in a very good lesson which has them watch video, conduct experiments, complete hands-on activities, and work in cooperative groups. The educationally-rich activities are clearly-explained, and the group...

In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The lesson gives learners practice making salicylate solutions, using spectrophotometers, calculating dilution amounts,...

After taking in background information on teeth, marble, eggshell, and fluoride, chemistry aces design an experiment. Their goal is to demonstrate whether or not fluoride has a similar effect on marble or eggshell as it does on tooth...

Two scenarios are presented for chemistry detectives to decipher. Both require the use of an infrared spectrometer and focus on the examination of polymer materials. In the first, lumps in polyethylene bottles are analyzed. In the...

Pair earth scientists up to use an amazing online arctic portal mapping tool and Google Earth to analyze permafrost changes. They compare changes to data on atmospheric concentrations of methane to see if there is a correlation. Then...

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...

This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...

General chemistry classes practice spectroscopy. They grasp the relationships between wavelength, absorbance, and solution concentration. Additionally, they gain valuable practice using laboratory equipment such as burets and pipettes....

What is your attitude on health and illness? By considering their own experiences, students will reflect on and discuss their attitudes toward health and illness while educating each other by researching illnesses in small groups,...

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...
