For this organic reactions worksheet, students are given descriptions of the seven types of reaction of organic compounds. They then answer six questions about these reactions.

Students observe an electrolytic titration using a conductivity tester. In this titration lesson, students observe a solution of acid conducting electricity using the conductivity apparatus. They observe the acid solution being titrated...

Eighth graders investigate the water cycle and its processes. They examine temperature and precipiation data to classify climate of ten cities. They then create a climate map of the world.

Learners conduct a scientific investigation about the formation of stalactites and stalagmites. They conduct an experiment to reproduce them in the lab environment. Students make observations over a period of time in order to see the...

In this lipid worksheet, high schoolers answer questions about the structure and functions of lipids. They read about the three main lipids in the body including triglycerides, phospholipids and cholesterol and answer questions about each.

For this catalysts worksheet, students use transition metal ions to catalyze oxidation reactions of iodide ions. Students measure the rate of the reactions by measuring free iodine as a product.

Young scholars create psychrometers to measure the humidity of the air.  In this meteorology lesson, students make a wet-bulb thermomter and place it next to a dry-bulb thermometer to measure the relative humidity in the room.

Students discuss nutrition and how to make better choices with food. In this algebra and nutrition lesson, students discuss the way the body process food and the importance of nutrition for our cells. They discuss calories, fats and...

Students investigate different journalistic techniques used to add color and new dimension to fact-based news stories. They write a journal discussing techniques that journalists could use to make Michael Jordan's retirement from the NBA...

In these creative hands-on activities, learners construct several different molecular models that represent substances that play an essential role in our nutritional needs. Using gum drops and toothpicks, students design the models....

Students build a model to simulate parts of the water cycle. They recognize and explain the essential elements of the water cycle.

Students receive a basis for understanding the three main classifications of rock: igneous, sedimentary and metamorphic. They engage in a hands-on activity designed to give them an appreciation for rocks and minerals.

Learners observe the chemical reaction that occurs when salt is put on ice, and use the energy that is released to make ice cream.

Students identify the different types of mixtures. They identify examples of solutions, suspensions, colloidal dispersions, and emulsions through a game and basic experiments.

Learners examine how an aquifer operates. They discuss the implications of the groundwater becoming contaminated. They work together to create an aquifer model to observe the connection between surface water and groundwater.

Students obseve and compare molecular movement within water at various temperatures and of varying salinity. They discuss the movement of water on a larger scale which can affect the movement and concentrations of microbial populations...

Students identify various sources of nutritional information and evaluate accuracy of messages. They comprehend and identify misrepresentations in current food labeling. Pupils evaluate specific consumer products for truth in labeling....

Fifth graders identify the chemical and physical changes in the water cycle, carbon cycle, and the effects of weathering. They analyze the periodic table, and observe how vinegar reacts with limestone in a chemical reaction that causes...

Students explore the real experience with the sequence and process of caterpillar-to-butterfly metamorphosis. They actually get to watch the process unfold in the classroom. A Flex-Cam records the video of the process to assure that the...

Young scholars are introduced to the processes of evaporation and condensation as they observe physical changes in water. They observe how matter changes from a solid to a liquid state. Students are explained that steam is water in its...

Students examine Food Guide Pyramid and Dietary Guidelines. They look at samples of serving sizes, sort different foods into their correct groups, complete worksheets to discover which types of foods they eat regularly, and discuss...

In this science activity, students apply science basic knowledge of chemistry to the puzzles that are listed for the four parts of the sheet while focusing upon the identification of a metalloid.

In this molecular model learning exercise, students use a molecular model kit to construct 13 different molecule models. After constructing the molecules, the students complete 32 short answer questions.

For this enzyme worksheet, learners solve 6 problems including questions about how enzymes work, graphs of the relationship between enzyme and substrate and structures of enzymes.
