There is the same amount of water on earth now as there was when it was formed. The water from your faucet could contain molecules that dinosaurs drank! Young scientists build their own hydrologic cycle model and observe...

This is an amazing 33-page resource for teaching multiplication! Your mathematicians will discover the connection between multiplication and repeated addition. They also will work collaboratively with arrays while studying zoo animals....

Students conduct studies of states of matter. In this science lesson plan, students observe the properties of matter and classify different substances as solids, liquids, and gases.

Students investigate the freezing point depression of water while making ice cream. In this colligative properties lesson plan, students make ice cream using ice, salt and water to freeze milk and sugar. They measure the temperature of...

Students investigate the concept of diffusion and how materials enter and leave a cell. In this movement across a membrane lesson plan, students use perfume, food coloring in water and a sugar cube in water to observe diffusion. They...

Students investigate calorimetry and set up equipment to measure calories. In this calorimetry lesson plan, students make a calorimeter and compare large amounts of heated water with small amounts to show the difference in calories....

Students investigate diffusion using different solutions of chemicals placed in agar dishes. For this diffusion lesson plan, students observe 3 demonstrations of diffusion using perfume, food coloring in water and sugar cubes in water....

Fifth graders study the water cycle. In this science lesson plan, 5th graders distinguish among evaporation, condensation, and precipitation phases of the water cycle.

Student explore states of matter. In this science lesson plan, students define matter, identify the states of matter, tell about the properties of each state of matter, and demonstrate an understanding of the difference between a...

Students investigate factors affecting the rate of solubility. For this rate of solubility lesson plan, students experiment by crushing, heating and cooling solutes and solvents to see how the solubility is affected. For each situation,...

Students explore energy conversions by demonstrating the conversion of electrical energy into light, heat, sound, and magnetic energy. Students create a simple device that converts electrical energy from batteries to heat, light, sound...

Students experiment with a variety of materials used for insulation by melting ice cubes.

Observe the stages of the water cycle by completing 3 activities. To help understanding of the water cycle your students can observe evaporation, the formation of frost, vapor and water and the process of distillation which is used to...

Second graders examine how a food chain functions. They define what a food chain is, and act out a food chain with the students acting as different animals. Students then sing the song "I Know An Old Lady Who Swallowed a Fly," and...

Fifth graders prepare for a "Mad Scientists Fair" by creating a controlled study and by conducting experiments. They make and record observations and classify specimens according to characteristics. They compare results to their original...

Sixth graders explore the world of micro-organisms. In this science lesson plan, 6th graders discover additives which will deter micro-organism growth.

Students study weather and weather measurement tools. In this weather lesson, students read and discuss weather myths and superstitions as well as weather terminology. Students then work in groups to complete weather stations for wind,...

Students explore solids, liquids, and gases. In this states of water lesson, students conduct a scientific investigation that requires them to observe and note the differences among solid, liquids, and gases.

Students experiment with objects of different densities. In this density lesson plan, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density...

Students examine how a hot air balloon works. In this hot air balloon instructional activity, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when...

Learners investigate why cells divide. In this cell size lesson plan, students observe how far a solution travels into 3 different size model cells of agar. They answer questions about the most effect movement of "nutrients" into the...

Students explore digestion. In this Human Body lesson plan, students participate in six different activities pertaining to the Digestive System. Students gain understanding of digestion through experimentation and investigation. Students...
