Third graders find the radius and diameter of a bubble. In this radius and diameter lesson, 3rd graders create bubbles on their desk and find the radius and diameter of the bubble. Students work in partners to define circle terms and...

Students investigate osmosis using egg cells with the shells removed. In this osmosis lesson plan, students remove the shell of an egg by letting it soak in vinegar for two days. They take measurements and observe the cell. They soak the...

Students investigate the relationship between evaporation and temperature changes. In this evaporation and changes in temperature lesson, students measure the changes in temperature of different solutions on a cotton ball.

In this thermometric titration worksheet, high schoolers determine the concentrations of hydrochloric acid and ethanoic acid using a titration where they measure the temperature of the solution as it is titrated. The equivalence point is...

Students investigate the acidity and alkalinity of common household products in an experiment. They use red cabbage juice and litmus paper to show the difference between strong acids and bases as they work with vinegar, dish washing...

Drinking straws are a pretty simple device ... or, are they? Explore the possibility of sipping a beverage 30 feet away with an engaging activity that's sure to keep pupils guessing. Just place a long piece of plastic tubing in a glass,...

Differentiated instruction through leveled learning contracts boosts scholars' knowledge of volume and capacity. Participants split into three groups based on ability and interest before choosing three activities from their learning...

Can your class tell the difference between a burette and a pipette? Develop their lab apparatus knowledge using a series of puzzles. The online activity associates the name, image, and sizes of burettes, pipettes, volumetric flasks, and...

Students identify the various states of water. They use hypothesizing and hands-on experimenting on changing the states of water, the properties of water, and the role of heating and cooling in the changes of state.

Learners use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

In this burette-use learning exercise, students are given directions for titration using a burette. They practice reaching the end point of titrations and calculate the mean volume of three trials.

Students explore the world of nanotechnology by synthesizing ferrofluids in a series of chemical reactions. In small groups, they follow the procedure to create the ferrofluids using precise measuring techniques. They test the resulting...

In this classification of matter learning exercise, students answer 15 questions about solids, liquids and gases, types of mixtures and compounds vs. elements. They also answer 2 questions about measurement and 1 question about a biome.

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

Students design, build, and test the specifications (water displacement and load line) for a model boat. The lesson plan focuses especially on integrating design principles with inquiry-based experimental skills.

If students use and store kitchen equipment appropriately as well as utilize sanitary work habits, the foods laboratory will be a safe and easy place to work. See Preface Materials: As a motivator ask: "Why should I worry whether or not...

Students identify photosynthesis as a process through which organisms make their own food. They practice the process for writing the formula for the photosynthesis equation. Students describe how the processes of photosynthesis and...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Students explore tessellations. For this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-lesson unit on dissolving, this installment investigates the effect of temperature. If you consult the...

Playing with balloons, water, oil, and bottles help put this lesson over the top! Participants use air-filled balloons in water tanks to experience gas compression. They also use oil-filled bottles to experiment with buoyancy. Included...

Students investigate the coefficients in a chemical equation and their relation to moles. In this moles and coefficients lesson plan, students perform a single replacement reaction of copper (II) sulfate and zinc and find the ratio of...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...
