High schoolers investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the...

Students investigate inhalation and exhalation of the respiratory system. They construct a model of the respiratory system using balloons, straws, cups, and rubber bands. Then, they observe inhalation and exhalation and measure the...

Students investigate acid rain. In this environmental lesson, students participate in an experiment using litmus paper and various liquids and then test the acidity of the liquids. Students identify reasons why acid is harmful to the...

For this formula for magnesium oxide worksheet, students perform an oxidation reaction between magnesium and the oxygen in the air to produce magnesium oxide. Using the known masses of the magnesium and the end product, students find the...

Young scholars analyze how clouds form. In this cloud formation lesson, learners brainstorm types of clouds and what they think they're made of. Young scholars conduct an experiment to see how clouds form and discuss their observations....

Fifth graders explore osmosis as they watch organisms divide.  In this organism lesson, 5th graders use potatoes to experiment with the effects of salty water in the body.  Students discuss what osmosis is and record what...

Students investigate the physics of flight by experimenting in class.  In this history of flight lesson, students define terms such as gravity, lift, and drag in order to better understand how a plane is able to stay in the air....

Students explore cycles in nature. In this cross curriculum agriculture lesson, students define "cycle" and research weather and planting folklore. Students make a bracelet in which individual colored beads represent the many "cycles" of...

Students determine which of the following parameters, slope, ice, temperature or basal condition affects the glacier speed the most. They create their own experiment to test what influences glacier speed and temperature of the ice.

Second graders conduct a plant experiment.  In this basic needs of plants instructional activity, 2nd graders observe plants for two weeks. Students record data from their plants in journals. 

Fourth graders observe what is happening when an Alka-Seltzer tablet is placed in a clear cup of water. They observe the release of carbon dioxide gas. Pupils answer the question of how much as is released by observing the experiment...

Young scholars analyze an apple. In this lesson about developing inquiry skills, students do an experiment with an apple. Young scholars make several observations about the apple. Students answer questions to help them improve and...

Students use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...

Sixth graders read Hatchet by Gary Paulsen, discuss refraction, identify example of it from novel, and perform classroom experiments demonstrating refraction and reflection.

Students explore the uses of insulation and describe how insulation helps to conserve energy. They work in groups and use plastic, wool, paper and aluminum to experiment with the heat-retaining properties of various materials.

Students will examine the physics of flight through using experimental inquiry. For this lesson, you'll introduce your students to the four forces of flight--drag, lift, thrust, and weight--through a variety of fun-filled flight...

In this science activity, students examine the topic in order to solidify knowledge covered in the curriculum using puzzles and creative games.

Students define vocabulary related to the parts of the atom.  In this matter instructional activity, students navigate the web to find the structure and the forces that affect atoms.  Students complete an experiment with...

Students predict and test how the effects of velocity and force of an object or air on water affect the waves created. They diagram a water park ride using their knowledge of these effects to create their desired outcomes.

Students experiment with the concepts of absorption and reflection of radiant energy.

Students examine the concept of transpiration. They work together to complete an experiment in which they see water loss in plants. They record their observations and discuss their conclusions.

Students experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables the student to determine the originator of the "epidemic." They transfer live bacteria by hand contact, then...

Fifth graders compare and identify variables that affect the rate of a chemical change using Alka-Seltzer, water, ice, and hot water. They time how long each variable takes to pop the canister into the air, and record the results on a...

Students choose a current environmental issue and research historical conditions as well as present conditions. They assess the changes in ecosystems, populations of specific species, air quality, or any other aspect of an ecosystem.
