Fifth graders observe and conduct a variety of experiments to differentiate between physical and chemical changes. They mix cabbage juice with different liquids and record their observations on a chart. Students write down their...

Students identify seasonal changes. In this seasons lesson, students choose a tree on the playground to observe each season. Students record their observations throughout the year and create personal seasonal booklets.

Students develop simple observations. They observe bleeding of colored inks with water, to understand mixtures, and to make generalized inferences from their observations.

Learners use the Archimedes method to demonstrate scientific principles behind observations.

Students examine the changes as water goes from solid to liquid. In this states of matter instructional activity, students observe and record the changes to water as it changes from solid to liquid and back to solid.

Learners explore how various substances change from a solid to a liquid or from a liquid to a solid and how temperature, pressure and nature play an important role in this process. In this melting and freezing...

Students investigate oxidation and reduction reactions. For this oxidation and reduction lesson plan, students construct an electroplating device and perform an oxidation/ reduction reaction. Students describe the chemical changes that...

Seventh graders investigate the fermentation process and the chemical changes that take place. In this fermentation lesson plan, 7th graders mix extracted apple juice with yeast and sugar water and observe the reaction over the course of...

Young scholars investigate the changes of their environment by experimenting with photography.  For this environmental observation lesson, students compare historic photographs of areas with pictures they have just taken....

Students investigate the properties of solids, liquids and gases. In this states of matter lesson plan, students observe dry ice and its characteristics. They calculate the density of dry ice and observe the sublimation of the dry ice...

Students collect, observe, sort, and measure leaves. In this leaf lesson, students take a walk to collect leaves. They bring the leaves back into the classroom to observe, sort, and measure them. They visit a website to learn more about...

Students observe fluid motion. For this Physics lesson, students explore the principles of Pascal, Archimedes, and Bernoulli. Students list their experiences with fluid movement.

Students observe the life cycle of a butterfly. They read butterfly/caterpillar themed books. They sequence the lifecycle from eggs on a leaf to an adult butterfly. They release their butterflies into a natural habitat after singing and...

Students select an invention from a list, observe the invention for one whole day to determine how their selected invention impacts their daily life. They share their observations as a class and describe their experiences.

Fifth graders investigate chemical reactions. In this physical science lesson, 5th graders make dry ice root beer and identify the type of change that occurs to the root beer mixture.

Fifth graders evaluate the physical properties of 5 powders. Each powder is subject to different conditions. They describe each observation as with a chemical change or a physical change.

Students conduct a number of simple experiments, collect and categorize the results as either chemical or physical change. The lesson uses connections to folklore, science fiction and comic books to assist each student as they make...

Students distinguish between physical changes and chemical changes. They comprehend that chemical reactions produce new substances with compositions and properites which are different than those of the starting materials. Pupils also...

Students construct and maintain model of natural habitat, suggest improvements to the model of the natural habitat to make it more realistic and habitable, and demonstrate careful observation and recording of how animals survive in their...

In this rusting, burning and oxygen learning exercise, students read about chemical reactions and are given diagrams of a rusting bicycle, a burning candle, and a variety of chemical changes. Students make observations and explain the...

Students investigate molecule movement according to the kinetic molecular theory. In this kinetic molecular theory lesson plan, students observe demonstrations showing that molecules speed up with increasing temperature and slow down...

For this mixtures worksheet, students experiment with different amounts of solutes and solvents to make solutions. They observe color changes and look for chemical and physical changes in the test tubes. Students answer 5 questions and...

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 study the concept of a scientific model and demonstrate climate change models.  In this scientific lesson students design a model using direct and indirect evidence and use it to make hypotheses.
