Working out the Shapes of Molecules
For this molecular geometry worksheet, students are given the directions and 4 examples as to how to predict the geometry of molecules. They determine if the molecules are pyramidal or trigonal bipyramidal.
Curated OER
Naming Acids
In this naming acids worksheet, students are given a chart with polyatomic ions and acid names with oxidation states, prefixes and suffixes. They use the chart to help name the eighteen given acids.
Curated OER
Ladders of Life
Students explore the field of genetics. They examine four basic traits. Students demonstrate their knowledge of phenotype and genotype by charting their personal traits. Students compelte a Meiosis chart. From the chart results,...
Curated OER
The Water Cycle
Fifth graders investigate evaporation, condensation, and precipitation. They observe a water cycle kit and record their observations, and examine how water condenses on the outside of a cup. Next, they observe an evaporation...
Curated OER
Acid Rain
Students understand the dynamics of acid rain and its impact on the living and non-living environment. They hypothesize how acid rain affects water pH levels in two lake systems with differing watershed features.
Curated OER
Exothermic and Endothermic Reactions
Students observe demonstrations of exothermic and endothermic reactions and determine the changes that take place in a chemical reaction. Students observe four demonstrations showing entropy, attraction of molecules due to polarity,...

A Star Sheds a Comet Tail!
In this comet tails and stars worksheet, students read about the star Mira and the vast clouds of gases it emits. They use a photograph from the Galaxy Evolution Explorer satellite to solve 5 problems about the scale of the image, the...
Curated OER
Carbon Dating
Simulate C-14 decay using M&M and Reese's Pieces candies. In this scatter-plot lesson, students perform an experiment to simulate the half life of C-14. Information is plotted on a scatter-plot. Students answer four comprehension...
Curated OER
CONSTRUCTION OF A HEMOGLOBIN GENE
Young scholars use research to see how eight pairs of triplets are equivalent to part of a gene and control a part of heredity. They also understand how red blood corpuscles manufacture normal hemoglobin.
Curated OER
DNA the Easy Way (and "Gram Stain" Without the Mess)
Learners visualize DNA from cells and explain the basis and importance of the Gram-stain reaction and to perform the KOH test equivalent.

Nutrient Biochemistry
In this nutrient biochemistry worksheet, students complete the blanks with information about nucleic acids and the process. Students also draw a figure referenced in the text given.
Curated OER
DNA Fingerprinting
Pupils experiment with chromatography as a technique which is similar to electrophoresis that scientists use to identify DNA samples.
Curated OER
Replication of DNA
In this replication of DNA instructional activity, learners match the correct definition of DNA replication to the terms given. Students also complete given statements with the correct term in the space provided.
Curated OER
Characterizing Drosophila Mutants
Learners investigate wild-type and several mutant varieties of Drosophila melanogaster, which are characterized and distinguished according to pteridine pigments. They discoverthat paper chromatography of the wild-type Drosophila results...

Extraction of DNA from Onion
Students study DNA by isolating it from plant tissue. They determine the purpose of each step in the isolation procedure as it relates to the physical and biochemical characteristics of the genetic material
Curated OER
Extraction of DNA from Onion
Students experiment with DNA by isolating it from plant tissue. They investigate whole onions to prepare DNA. They complete the experiment to examine the structural characteristics of DNA.
