The Structure of DNA
Students will demonstrate knowledge of the structure of DNA by constructing simple models of DNA with materials given to them in class. They will also discover that some female scientists such as Rosalind Franklin have not been given...
Curated OER
Structural Changes in a Protein
Students observe and manipulate the structure of a protein. They form an alpha helix, a beta sheet, and add disulfide bonds. They create a multimeric protein and compare their location with other students.
Curated OER
Behavior and Properties of Gases
Students convert Celsius to Kelvin temperature. Students conduct three lab experiments, gas law simulations using Internet applets, lectures and demonstrations. The Laws included are Boyle's, Charles, Combined Gas, Ideal Gas, and Gram's...
Curated OER
The Carbon Cycle
Fifth graders examine the carbon cycle, periodic table, and photosynthesis and respiration. They analyze the periodic table and how it is organized, then complete the "Elementary, Dear Watson" worksheet. Students then examine a carbon...
Curated OER
Activity #18 Decompostion of Baking Soda
Students observe what occurs as baking soda is heated. They explain why a chemical rather than a physical change occurred during the procedure. Pupils identify the tpe of reaction (decomposition). Students conduct a glowing splint...
Curated OER
Activity #17 Co2 From Alka Seltzer
Learners observe what occurs when Alka Seltzer tablets are added to water. They explain why water stays in the jar when it is above the surface of the water. Pupils test for the presence of carbon dioxide by conduting the match test.
Curated OER
A Helthy Diet
Students examine their eating habits and experience analyzing data and drawing conclusions. They construct models of the molecular backbone of saturated and unsaturated fats. In addition, they examine the labels of their food, record...
Curated OER
HAPPY SOIL, SAD SOIL
Students will be able to identify the characteristics of healthy soil and unhealthy soil.Take the class outside to an area of thick grass near trees, if available. Compare the
clothes people wear to the thin cover. Discuss the reasons...
Curated OER
COMPARE SOILS BY GROWING PLANTS
The student will identify the difference in the rate of plant growth in three soils that vary in organic matter.1. Obtain three to four flowerpots, different types of soil, a record chart, three to five beans for each pot, and water....
Curated OER
What is Photosynthesis?
Young scholars investigate the similarities and differences of living things. Specifically, students will be able to identify the life processes of photosynthesis and describe the basic needs of plants.
Curated OER
Metals, Nonmetals, Metalloids
Students recognize that metals, nonmetals, and metalloids have common attributes. They Identify physical and chemical properties. Students define ores and identify where ores can be found.
Curated OER
Genetics DNA Replication
Students explore DNA replication. Beginning with a teacher led discussion, students examine inherited information, genes, and Deoxyribose Nucleic Acid (DNA). As the teacher models the structures of DNA, tells about the contributions of...
