Students create an animation of a cell process and insert it into a presentation. They choose a cellular process such as mitosis, osmosis or DNA replication, and create a simple 2D animation.

Students explore how present biotechnology has evolved. They create a timeline is included referencing major scientists and major events in history which have led to our current understanding and use. A teacher time line is included.

Students simulate the Sanger method of DNA sequencing using color pop-beads as a representation of nucleotides and dideoxynucleotides. Students assemble DNA sequences and run their sequences through a "sequencing gel" and sketch what...

Students investigate the dangers of radiation by exploring recent nuclear tragedies.  In this scientific debate lesson, students define the idea of radiation "half life" and determine if low doses of radiation are truly damaging to...

Students extract their own DNA from cheek cells. In this biology instructional activity, students explain the replication process. They identify the structure and composition of DNA.

In this electrochemistry worksheet, students are given details as to how to solve strengths of oxidizing and reducing agents, battery chemistry and a summary of cell construction and convention.

Students investigate the effects of an acid and a base on the structure of milk protein. They observe the changes to droplets of milk when adding ammonia and lemon juice and relate the changes to old, curdled milk. An extension using...

In this pH worksheet, students read about pH and the concentration of ions in solutions that are acidic and basic. They answer four questions about pH and determine the concentration of hydronium ions and the pH given concentrations of...

Learners see how an infectious disease such as AIDS may be quickly transmitted throughout a population. They conduct a simulated transmission of an infectious disease and mathematically determine the number of possible infected individuals.

Students use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...

In this water instructional activity, students read about hydrogen bonds in water and the differences in electronegativity between the oxygen atom and the two hydrogen atoms in water. Students answer four questions about the structure of...

Students write and balance five chemcial equations which have been observed throughout the process of completing the experiment. They use vacuum filtration to recover suspeneded particals from a colloidal suspension. Students correctly...

Students examine the molecular studies of organisms that have led to a new era in their understanding of speciation and evolutionary relationships. Students study the allelic frequency of genes controlling specific molecules and assess...

Students examine solubility and the significance of water.  In this aqueous solution lesson students complete a lab activity on soil profiles.

In this chemical change worksheet, students conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...

In this chemistry worksheet, students write the structures for the compounds illustrated on the sheet. Then they name the compounds whose structures are illustrated in part two. Students also fill in the blanks to complete the paragraph...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Students examine the genetic relationships of different organisms. In groups, they discover the importance of genes and how different amino acids show various evolutionary relationships. They use an online database to continue their...

Students investigate the physical structure of a protein by using a computer simulation tool. They record its primary amino acid structure while viewing it in three dimensions for a better visual recognition. There is also a comparison...

In this stoichiometry worksheet, students practice calculating moles, molarity, and the concentration of a solution in molarity. This worksheet has 12 multiple choice questions and 3 problems to solve.
