Future geneticists use base pairing rules to build DNA and RNA polypeptide strands, and then explain both transcription and translation. Although the chains themselves are a little blurry, there is plenty of room in them for learners to...

Sixth graders explore the many uses of corn as a renewable source. In this biodegradable resource lesson, 6th graders investigate how corn is used in manufacturing and as a fuel. Students construct a piece of homemade plastic using...

Students discover how to determine the flavor of a jellybean using different key documents.  In this economics lesson, students discuss Virginia economics and begin an activity in which they will help decide on the what jellybean...

Students explore natural resources of our planet. In this natural resources lesson, students use an apple to explore the land, water, and climate. Students also use the apples to explore the part of our planet that can grow food and...

Students study apples. In this apple lesson, students read Apples by Gail Gibbons. Students discover the life cycle of apples and determine the many uses of apples. Students write a list of factual information on strips of construction...

Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

Chemistry classes pretend to be consultants to a grocery story trying to decide what polymer to use for therir new non-paper bags. They prepare tensile bars and use them to test plastic film samples for strength and stretchability. Both...

This organic chemistry lab activity is appropriate for teaching polymerization, percent yield, melting point, or the types and uses of polymer materials. Chemistry pupils imagine that they are working for a company to develop a special...

The four cycles in Earth's biogeochemical system are covered in this worksheet. Science stars fill in the blanks or define vocabulary terms pertaining to the hydrologic, carbon, nitrogen, and phosphorous cycles. This resource provides a...

How often do you find a science worksheet that comes with separate teacher's instructions? Here is one of those rare instances. Goals and objectives, materials, and evaluation guidelines precede the actual assignment. Biology leaners...

Compare and contrast eukaryotes, prokaryotes, and viruses with a chart and a Venn diagram. Beginning microbiologists consider motility, reproductive ability, DNA content, and the presence of organelles. They write short answers to...

The intent of this series of activities is to introduce high schoolers to the field of chemical instrumentaiton. They perform a few basic chemistry lab techniques: pH titration, paper, gas, and liquid chromatography, ultraviolet and...

Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...

Chemists consider a situation in which an ethanol producer needs to determine how much to add to t-butanol to prevent freezing during transport. They work in the laboratory to obtain the freezing point depression constant for the...

Here is a different approach to solutions: a worksheet that has chemistry learners use words to describe them! This is an outstanding exercise that will stretch learners to show what they know. They answer questions comparing solutions,...

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

Here is a general chemistry worksheet that incorporates practical applications. Four questions employ critical thinking about solutions, boiling and freezing points, and molar mass. Your class will practice what they learn in class by...

A neat presentation and challenging content make this solutions worksheet an ideal homework assignment for your budding chemists. Short answer and problem solving questions get them to review molarity, products, and reactants.

Here is a chemistry worksheet that was designed for a specific textbook section dealing with oxidation-reduction reactions, but it can be used in conjunction with any general chemistry curriculum. To complete the page, learners must...

Here is a short, but well-rounded review of redox reactions. Chemistry apprentices identify the type of reaction, write half-reaction equations, balance equations, and assign oxidation numbers. Being brief, this would make a purposeful...

If you need a homework assignment for your chemistry class, add this one to the possibilities. This assignment is composed of six questions including the identification of oxidizing and reducing agents, recognizing different redox...

Students consider the development of different societies. In this environmental building lesson, students consider local resources and how societies choose to use them. Students use their findings to design a 'green' building for use in...

Students discover how worms contribute to the balance of the environment. In this composting lesson, students study the composting and decomposition processes. Students then create habitats for worms that allow them to do their jobs.
