Students explore the different properties of water. They experimenting with different activities, each one explaining a different property of water. Students read an article "Small, Ues, But Might: The Molecule Called Water." and then...

Pupils explain that heat energy in a material consists of the disordered motions of its atoms or molecules. They know and explain that transformations of energy usually transform some energy into the form of heat, which dissipates by...

In this nutrition worksheet, learners describe what nutrient is and how the energy it has is measured. Then they explain what is meant by interconversion of molecules. Students also list the common vitamins and mineral required by the...

In this water and diffusion worksheet, students will explore the characteristics of water and the water molecule. Students will also answer questions about diffusion and the movement of materials due to concentration differences. This...

Students add borax to a latex polymer and play with it to see the characteristics it now contains. In this polymer lesson plan, students see if it stretches, if it's durable, if the molecules break easily, and more.

Students cut out the nucleotide models and have an opportunity to relax and chat. Using imagination, students pretend to be molecules acting out protein synthesis and whole body movement.

Students test for amaylase enzyme in a variety of substances. Student pairs perform a series of tests to determine how long it takes the starch sample to change to sugar molecules and the blue color to disappear when various saliva...

Fourth graders, in pairs, examine how every cell contains a 'blueprint' coded in DNA molecules. They use a DNA template to determine the m-RNA and t-RNA sequences for protein.

Students create a paper model of a plasmid and insert a DNA molecule that contains a specific gene into the plasmid. They complete an actual transformation involving E. coli bacterium and relate the two activities to one another.

Learners explore the layers of earth's atmosphere and conduct an experiment to identify carbon dioxide. They construct models using styrofoam to represent molecules in the atmosphere's layers. To discover how sunlight efffects...

Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. They describe how sound needs molecules to move and that changing the medium that it travels through changes the...

Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Students explore the progression of discoveries that have led to the genetics knowledge that scientists currently have. In groups, students research scientists that have made important contributions to understanding the molecules behind...

High schoolers use this laboratory exercise, restriction enzymes to recognize a four-, six-, and eight-nucleotide sequence. Assuming that the four component nucleotides (A, C, T, G) are distributed randomly within a DNA molecule, then...

Students role play molecules in a container as the container is heated to develop a definition of heat and temperature. They also observe demonstrations of conduction, convection, radiation, and phase transfer. Using these observations...

Students explore diffusion and active transport. They observe the effects of eggs in vinegar and predict what will happen when eggs are placed in corn syrup with food coloring. Students complete worksheets which lead them to describe...

Eighth graders interpret the chemical symbols and shorthand used for molecules and equations. Through guided practice, 8th graders work to decipher and interpret the symbols for chemical equations. An opportunity for independent...

In this chemistry worksheet, students name each of the branched alkanes presented on the sheet. Then they draw the structural formulas for the molecules.

In this molarity learning exercise, students calculate the molarity of 13 different molecules. Students also determine the concentration of given solutions. This learning exercise has 19 word problems.

In this genetics worksheet, students compare structures of molecules, compare the function of genetic enzymes, and compare transcription and translation. This worksheet has 2 multiple choice and 20 matching questions.

For this compounds worksheet, students identify molecules as compounds and provide a reason why they believe it is or is not a compound. Students write out chemical formulas. This worksheet has three problems to solve.

In this chemistry activity, students determine the number of water molecules is a given volume of water. Students determine the empirical formula for given compounds from the percentage mass of elements. This activity has 20 problems to...

Learners examine molecules and the changes in energy of a system.  For this energy systems lesson students complete a lab activity and describe changes of state.

This activity focuses on calculations involving gases. The students will be solving for the number of molecules, gas pressure, partial pressures, and volumes of different gases.
