Students examine the concept of radioactive dating. In this radioactive dating lesson plan, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.

Learners watch a demonstration on how volcanoes work. In this volcano demonstration, students watch the teacher demonstrate a volcanic eruption. The teacher will change variables used to create the eruption and the learners will predict...

Students research African-American mathematicians.  In this middle school mathematics instructional activity, students celebrate Black History by conducting Internet research on an African-American, mathematicians or...

Students explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are dissolved or...

Learners experiment with inner tubes, weights, flasks, and pistons to demonstrate the gas laws. In this molecular motion instructional activity, students demonstrate pressure as a force per area. They conduct an experiment to show the...

Students examine seven spiders and put them into two or three groups based on their structural similarities. In groups, they create a cladogram proposing possible ancestral relationships. Students design an experiment related to their...

Students create a mushroom spore design on paper while studying the facts on fungi.

Students explore the science of toxicology and the relationship between a toxic reaction (response) and amount of substance (dose). They observe two demonstrations illustrating the concept of dose-response.

Students comprehend that a chemcial change produce substances with a different composition and physical and chemcial properties. They state the differences between physical and chemical changes. Pupils observe changes that occur during...

Students gain information on how sailors, and to a larger extent how people in general, lived in the 18th Century. They are shown how the life of the sailor is different from their life, so they can see how different people live.

Fourth graders, in groups, examine the effect of heat on bonding forces by doing laboratory work.

Students read about the care and use of small kitchen appliances and correctly use several of the appliances.

Students see that solar energy is the energy given off by the sun. They explain that when light energy is absorbed by objects it is changed to heat energy and that dark-colored objects absorb more light and store more heat from sunlight.

Students investigate the separation of mixtures using plant pigments. Using everyday items, they demonstrate the separation of pigments in plants through the process of chromatography.

Students explore acids and bases. They experience the sour taste of acids and the bitter taste of bases by tasting substances such as chocolate, lemon juice, and baking soda. in addition, they complete a worksheet for individual assessment.

Students explore the natural distallation process that occurs in the water cycle. They use plastic cups and cotton swabs to observe the condensation process that is evident in the water cycle.

In this growing tomatoes worksheet, learners experience and participate in the process of growing tomatoes over a three or four month span of time. Students follow six directives in producing tomato plants.

In this growing tomatoes worksheet, students plant tomato seeds in February, and follow their growth through the summer break. They observe and investigate the plant growth from seed to plant.

Students explore Ultraviolet detecting beads and conduct several investigations with them.  For this investigative lesson students participate in an experiment to see the harmful effects of UV light and discuss their findings. 

Students identify the physical and chemical properties and explore the differences.  In physical and chemical property instructional activity students test polymers for the differences between the physical and chemical properties,...

Students investigate solar energy. In this solar energy lesson, students compare how heat is absorbed in light-colored objects and dark-colored objects by making S'mores.

Students cook with the power of the sun. In this solar energy lesson, students explore solar cooking as they apply scientific principles to cook s'mores.

Students explore the world of polymers. In this chemistry lesson, students make polymers and observe their properties. Follow-up questions and extension activities are included.

Students investigate proper training techniques for pets by creating a list.  In this domesticated animal activity, students identify traits of a good neighbor and relate those traits to a pet.  Students create lists of the...
