Students are introduced to working with molecular data. The first activity does both simulated and original data are used to compare amino acid, protein or DNA differences to construct phylogenetic trees or cladograms. These activities...

Students use the internet to research air bags in cars and trucks. In groups, they discover air bags history and the safety issues surrounding them. They create their own design of a new air bag and test it using a raw egg in...

Fourth graders identify the characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and separate or sort items using these properties. Students explain...

In this biology worksheet, students complete a crossword puzzle with 35 questions on protein synthesis. They identify the different parts of the cell involved in the process.

Students construct segments of DNA to create a piece of jewelry.  In this genetics lesson students create a DNA sequence that they turn into something to wear. 

In this naming formulas worksheet, high schoolers name 50 given chemical formulas of ionic compounds and covalent compounds including acids, bases, salts and gases.

In this biology worksheet, students complete a crossword puzzle with 39 questions on taxonomy. They identify the different classification systems used in biology.

Pupils investigate variation in the beta globin gene by identifying base changes that do and do not alter function, and by using several Internet-based resources to consider the significance in different environments of the base change...

Students participate in a hands-on activity to investigate how water is recycled in a small environment, and determine how water is cycled on earth.

Middle schoolers apply the scientific method and safety rules to aquatic pH. They test unknown solutions for pH levels.

Students explore the tissues of the bone. They discuss bone composition and physiology. Students perform experiments to compare and contrast the decalcifying properties of several liquids.

Students research topics. They teach a lesson based on their chosen topic to other students.

Students work together to identify the structure of DNA. They practice using new vocabulary as well. They create a 3-D model of DNA to complete the instructional activity.

Students construct paper model of the DNA molecule.  In this genetics lesson, students assemble paper parts that represent nucleotides into a DNA molecule.  Extension ideas are also provided.

Young scholars explore a series of activities on using BLAST. In this biology lesson, students explain the significance of BLAST in DNA query. They give real world applications of BLAST.

Students participate in a simulation of electrophoresis separation of DNA fragments. They link arms to form DNA fragments with each student representing a nucleotide. As they move through an obstacle course they discover how fragments...

Students applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.

Students 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.

Students separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.

In this chemistry 302 worksheet, students determine if the reaction is a battery or electrolytic. Kids balance the reaction and then indicate which species is receiving the electrons. Students fill in a table for a battery made from the...

Students imagine themselves working as research scientists completing the end-steps of a molecular research project and interpreting the data. They compare the gene sequences of normal and abnormal mice and evaluate the protein product...

Students discover how underground rock formations grow. They perform various activities based on grade level.

Students compare/contrast the DNA sequence data of the rat GULO gene to the inactive human GULO gene. They translate and align the sequences, and propose a scenario to explain the occurrence of an inactive DNA sequence to that of an...

Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
