Make a splash with young scientists as you teach them all about water using this activity packet. Thirstin, a cartoon glass of water, walks children through the water treatment process, teaches them about different sources of water, and...

Create a coat of armor for dinosaur volunteers. Young scientists explore the oxidation-reduction reaction facilitated by electric current. The result of the reaction is a dinosaur coated in copper and zinc, which leads to an...

Tenth graders use a classification key to identify organisms.  In this classification lesson plan students identify freshwater species of fish and document their observations. 

Explore homeostasis in animals with this all-encompassing worksheet. Advanced biology pupils consider a variety of mechanisms for maintaining internal conditions such as temperature and waste products. Eighteen short-answer questions...

When nature calls, you need to answer. Physiology learners discover that it is a just your body's way of regulating pressure and water content. Along with osmoregulation, they also examine thermoregulation, two vital processes with which...

Complete with teachers' notes for most of the slides, this is a tremendous presentation of the four types of tissues: epithelial, connective, nerve, and muscle. Each is displayed with pertinent vocabulary and photos of microscope slides...

Water, water, everywhere, right? Wrong. Learners assess their own knowledge of water availability on Earth. Then, through a reading, a teacher-led presentation, and an activity, pupils learn about the importance of available clean...

For this biology worksheet, learners take part in an examination of the graphic organizer to determine the different types of environments and how they effect the survival of microbes.

A solid review of the excretion system that presents diagrams and asks learners to name the labelled parts or to identify which parts perform the particular jobs stated.

In this nephron worksheet, students color the parts of the nephron and answer five questions about the structures and functions of the parts of the nephron.

Students discuss ammonia, and ways it may get into the aquarium. They complete a worksheet about the Nitrogen Cycle. Students learn how to get the ammonia and nitrite out of their aquarium.

For this thermal decomposition of calcium carbonate learning exercise, students perform three experiments on calcium carbonate, make observations, and write the equations for each reaction. Students explain in detail what happened at...

Students enter the room, receive a film canister that contains materials that be added to the dirty water bell jar. They record on their data table who or what is doing the adding and the actual substance that has been added to the bell...

Students examine the structure, function, and characteristics of microscopic organisms that inhabit freshwater through collection of water samples and observation through microscopes.

Students examine how river travel affected the Lewis and Clark expedition. They define gravity, slope, and velocity, conduct a river formations experiment, complete an activity sheet, and watch a video about Lewis and Clark.

Students perform two experiments to show the properties of enzymes. They use pectinase to produce apple juice from applesauce to show enzyme action and then taste the difference between raw and boiled papaya seeds as evidence of enzyme...

For this drinking water worksheet, students complete a crossword puzzle given 23 clues about drinking water purification, water content, contaminants, and softeners.

In this tissue activity, students are given notes on 6 types of epithelial tissues, 10 examples of connective tissue, three types of muscular tissue and the components of nerve tissue.

Fifth graders design an experiment in which they separate mixtures. In this mixtures lesson, 5th graders define mixtures, solutions, solutes, and solvents. They watch a video, complete worksheets, and perform an experiment to separate...

Students examine how water is treated prior to becoming available for human consumption. In this water treatment lesson plan, students conduct an experiment in which they filter water. Students formulate a hypothesis, test, analyze data,...

Students identify the different stages in the water cycle. In this environmental science lesson, students research about different water pollutants in watershed. They describe ways to purify water.

Students study the process of water purification and explain why it was important to treat it.  In this water purification lesson plan students purify drinking water and explain the factors that affect water quality. 

Learners work together to perform simple experiments discovering the properties of air. They share their results with their classmates. They examine how engineers use the properties of air to clean the air of pollutants.

Students design and construct a water filter using activated carbon, cotton and other materials to remove chocolate powder from water. They test and record their observations, and complete a KWL chart.
