Students study the biodiversity in pond water. In this biodiversity lesson plan, students observe 3 samples of pond water using a pond water identification sheet. They record their findings and identify the organisms they find, the...

Students investigate the physics of heating and cooling through conduction, convection, and radiation. Working in groups, they determine the best way to cool a can of water and warm a can of water. Temperature is taken at five minute...

In this groundwater pollution worksheet, students use a piece of bread to represent the earth, food coloring to represent contaminants in the ground and water to simulate the movement of pollutants with water through the ground. Students...

Second graders discover what changes occur in various types of matter under different conditions. They make predictions about the changes in an apple left out in the air, water placed in a freezer, and a nail left in a cup of water. They...

Young scholars create models of the earth's atmosphere to explore how gases that are dissolved in water can eventually create acid rain. After conducting a series of experiments within their models of the earth's atmosphere, students...

Students list conditions necessary for humans to survive. They then mix yeast with a nutrient broth consisting of warm water and table sugar in a plastic bottle, capping it with a party balloon and compare the factors within the bottle...

Students investigate osmotic balance in living cells. In this osmotic balance lesson plan, students use elodea leaves to study the effects of salt solutions on the cell. They compare the changes in an elodea leaf with salt water on it to...

Students investigate refraction and reflection of light. In this light lesson plan, students perform 3 activities to observe light interacting with matter by using a flashlight. They explore refraction using a glass of water and...

Middle schoolers compare the absorbency of a regular diaper and a swim diaper in fresh water and salt water. In this absorbency lesson plan, students mass the diapers and place them in water and determine the change in mass. They do the...

Young scholars collect and examine microscopic life from a local pond. In this biology lesson, students examine local pond water, searching for protozoa, with the use of a microscope. Young scholars identify the various life forms in...

Young scholars explore sinking and floating.  In this buoyancy lesson, students conduct an investigation dealing with regular and diet soda. Young scholars drop various soda cans into water and then discuss why some float and...

  Learners observe a leaf and discuss the way that water is released from a leaf through its stomata.  For this water cycle lesson, students calculate how much water leaves produce from a whole tree.     

  Students build boats out of clay to test the buoyancy of the boat in water.  Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.   

Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.

In this biology worksheet, students identify and define the vocabulary terms listed and make a prediction about the outcomes of the experiment. Then they complete the chart of the observations of the plankton diversity in drops of pond...

High schoolers decompose glucose and write an equation for the reaction. In this decomposition reaction lesson plan, students burn a sample of glucose and test the products for water using cobalt chloride paper. They write a balanced...

Students investigate photosynthesis in water plants. In this photosynthesis lesson plan, students use the elodea plant and observe gas bubbles released to determine the rate of photosynthesis. They vary the light intensity and the amount...

In this buffer solution worksheet, students experiment with the addition of different solutions to a buffer solution and observe the changes in pH using a pH probe. Students describe the differences among the addition of pure water and...

Learners examine how to take the impurities out of eater.  In this exploratory lesson students complete an experiment on how to filter drinking water. 

Students gain an understanding of how elevation affects the flow of water. They discuss issues that can arise when residents and industries upstream pollute or irrigate a river, in opposition to those downstream. They role play opposing...

Students discover how seeds travel from their parent plants in search of water, sunlight, and nutrients, and conduct experiments in which they note characteristics that encourage seed dispersal by means of wind, water, animal carriers,...

Students simulate the impact of fluctuating river volumes on structures and landforms. They experiment with table top-sized riverbed models and water. Students consider how human design can help mitigate the effects of a flood.

Students observe the effects of acid rain on plants. They simulate an experiment using vinegar or lemon water. They observe the impact of acids on plants and recognize how acid rain can affect the environment. They examine their plants...

Students explore the importance of natural resources. They are given copies of the story, "Who Cares For The Land," and students follow along as the teacher reads it. Students identify the key points in the story. (Soil, water and air...
