Curated OER
Balancing Chemical Equations
Ninth graders explain how atoms and molecules form different substances during chemical reactions and how these processes require losing, gaining or sharing electrons. They correctly write chemical formulas and show how a balanced...
Curated OER
Wondrous Water
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...
Curated OER
Thermal Energy and Heat Unit
Students 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...
Curated OER
Nutrition
In this nutrition worksheet, young scholars 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...
Curated OER
Water and Diffusion
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...
Curated OER
Fun Polymer Activity
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.
Curated OER
Nucleic Acids and Protein Synthesis
Learners 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.
Curated OER
Amylase Enzyme In Saliva
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...
Curated OER
Constructing a Protein Sentence
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.
Curated OER
Genetic Engineering/Biotechnology
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.
Curated OER
Earth's Atmosphere and Temperature
Students 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...
Curated OER
Traveling Sound
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...
Curated OER
Differentiate Elements, Compounds, and Mixtures
Young scholars 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...
Curated OER
Genome's Greatest Hits
Pupils 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...
Curated OER
COMPARISON OF FOUR-, SIX-, AND EIGHT-bp CUTS IN CALF THYMUS DNA
Students 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 any...
Curated OER
Heat And Heat Transfer
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...
Curated OER
Osmosis
Pupils 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 the...
