Students make their own candy. In this science lesson plan, students observe how molecules interact with each other in physical changes and observe how the addition of heat can cause molecules to interact and form new molecules in...

Fifth graders carefully examine and investigate the products contained in a diaper. They particularly analyze the crystal sodium polyacrylate, a product developed for use in astronaut diapers. They follow the scientific method, forming...

Young scholars build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain...

Students construct models of the way water molecules arrange themselves in three physical states - solid, liquid, and gas. They explain the molecular behavior of ice, water, and water vapor.

Students, after observing the elements of a local watershed, explore the need to protect watersheds as water resources for the future. They examine the factors involved with a watershed: geology, ecology, and the effect of man's...

Sixth graders use the scientific method to test variables of evaporation. In this evaporation lesson plan, 6th graders test a wet handprint on a paper towel and relate this experiment to weather conditions.

In this thermodynamics worksheet, students fill in the blanks with terms related to specific heat, calorimetry, phase changes, enthalpy, entropy and free energy.

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 properties learning exercise, students write the correct term in the spaces beside each definition. Then, students unscramble the letters in the boxes to answer a riddle.

In this thermodynamics worksheet, students answer multiple choice questions about enthalpy and entropy, they calculate molar entropies and they determine equilibrium constants and free energy of reactions.

Students demonstrate the scientific method by conducting an ice cube melting experiment. They make predictions and observations, and conclude what factors make ice melt more slowly or quickly than normal.

Tenth graders examine the heating curve of water when head is added constantly over time. They input values into a calculator as they record water temperature every thirty seconds as it is heated on a hot plate. They complete the...

The PowerPoint opens with video footage of the decomposition of nitrogen triiodide and then explains it with diagrams. Graphs of exothermic and endothermic reactions are exhibited, as well as one for the effect of a catalyst on reaction...

In this rate worksheet, students draw and label given situations, determine the rates and the relationship between them. This two-page worksheet contains 7 multi-step problems.

Students model the arrangement of particles in a liquid. They use the model, to demonstrate how a gas is formed from a liquid with no increase in temperature as energy is added. Pupils model the arrangement and movement of gas particles.

Students demonstrate sound waves and make changes in the waves resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.

For this chemical and physical reactions worksheet, students read a 2 page science article, answer 10 statements as true or false, give 2 ways a chemical reaction is different from a physical reaction, answer 1 short answer question and...

Students observe water change from a liquid to a gas state when heated and then return to its liquid stage when cooled. They learn that gas molecules move faster than liquid molecules. They discover physical properties that describe how...

Third graders define and discuss evaporation, precipitation, condensation, and collection, color web pages to illustrate Water Cycle book, listen to stories about Water Cycle, play trivia game to demonstrate knowledge of what they...

Students define and discuss colonialism and self-determination. After reading the European's view on the topic, they analyze a map of imperialism in 1914. They watch excerpts of a video and take notes on various United Nations...

Students investigate various chemical reactions when creating mixtures in ziplock baggies. In this chemistry instructional activity, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies...

Third graders recognize the American flag as a symbol. In this symbols lesson plan, 3rd graders review the video "U.S. Flag: Proper Use" and identify what the stars and stripes represent. Students view an online clip of how to fold the...

In this gas laws worksheet, students complete 11 fill in the blanks and problem solving questions on Boyle's and Charles's laws.

Second graders look at different types of energy. In this energy lesson, 2nd graders define energy and the difference between kinetic and potential energy. They see examples with falling books and a slinky.
