Excited atoms lead to exciting lessons! Learners use heat and light to excite both atoms and molecules. They display their learning in the form of Bohr models depicting the excited state of the atoms.

Students are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

Students find moles and molecules used when a candle burns. In this moles and molecules lesson plan, students calculate the initial mass of a candle and the mass of a candle after it burns for 3 minutes. They calculate the mass lost when...

What makes up the air we breathe? Young scientists explore the atoms and molecules in the air. An interactive lesson allows individuals to watch the movement of the particles in the air and change the makeup from a mixture to a...

Pupils examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Things are about to heat up in your classroom! A kinesthetic lesson asks learners to play the part of the gases in the earth's atmosphere and interact with the sun's radiation. The focus is to learn the impact of the increasing...

Elements, to the rescue! Scholars first review the periodic table, and then learn about the first 20 elements and their properties and uses in the fourth of six lessons in the Mixtures and Solutions unit. Applying their newfound...

Biotechnology pros produce their own biofuel using waste oil and fresh vegetable oil. They test the quality of their product using titration techniques and pH analysis. They write their observations and report their findings. Be aware...

Students experiment to find which liquids are more dense.  In this density and mass instructional activity, students predict and then test objects to observe and measure their density. students observe which items sink and float....

Students analyze the way atoms function and how they combine to form molecules and various compounds. Using a software program, they create a diagram of an atom and write a summary about their functions. They complete a worksheet and...

Learners investigate plastics and learn they are giant molecules made of carbon atoms. For this polymers and plastics lesson, students perform 3 activities which all include making polymers from household items such as milk and vinegar,...

Examine how heat can be transferred between systems by reconstructing a diagram on energy flow and solving problems on heat flow and work done.

Candy is one of my favorite words, and it's an even better word when it relates to science. Yes, candy science can happen when you grow rock candy crystals with your class. The entire process for growing these edible wonders of nature is...

Liquids are what's the matter with the lesson! Learners investigate properties of different liquids as they interact with various types of paper. They then use their observations to identify a mystery liquid to finish the sixth lesson in...

Students experiment with states of matter with water and ice. In this states of matter lesson, students experiment to discover what happens to water as it freezes to become a solid, ice. They observe what happens when ice melts back to...

Looks don't tell the whole story. Young experimenters explore reactions with substances that look similar. They observe the reactions that take place when combined with baking soda and use indicators to conclude they react differently...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Fifth graders explore the phases of matter, make observations of matter, the physical and chemical properties of matter, solutions and mixtures, formation of molecules and atoms and molecules all through hands on activities.

Students determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different levels of...

Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

Students examine distribution of water and minerals. In this surface and groundwater lesson, students conduct an experiment with fresh and salt water making hypothesis and drawing conclusions about minerals. 

Learners observe a demonstration on how we see space between water molecules.  In this experimental lesson students discover what elements make up the things around them and discuss what they learned. 

Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...
