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 instructional activity 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...

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 instructional activity, students consider local resources and how societies choose to use them. Students use their findings to design a 'green'...

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.

If you need a straightforward and comprehensive organic chemistry exam, check this one out. Chemistry pupils identify functional groups in molecule diagrams, draw a Lewis structure, fill in a table about molecular shape, predict boiling...

Marine biologists research sea ice communities. Assign some groups to construct paper models of sea ice communities in winter, and some to construct models of them in summer. The lesson is simplistic, but the Internet resources provided...

In "The Nature of Covalent Bonding," chemistry hopefuls demonstrate an understanding of various types of covalent bonds, electron configuration, and resonance structures through fill in the blank, true or false, and matching questions....

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Comparative anatomy prevails in the lesson exploring diversity among invertebrates. Biologists examine physical characteristics of an earthworm from phylum annelida and a meal worm from phylum insecta. They also inspect a cricket and a...

Translate the process of protein synthesis to your molecular biologists with this instructional activity. It consists of reading, completing a table as a summary, comprehension questions, and a modeling activity for both transcription...

Reward biology learners for working hard in their mitosis lesson with a sweet snack at the end! They begin by twisting apart creme-filled cookies and using the icing as a cytoplasm. Colored candy sprinkles make up chromosome pairs,...

Focus on oxidation-reduction reactions with a review worksheet. Junior chemists answer short-answer questions before they write balanced half-reaction and full-reaction equations.

A handout on genetic inheritance begins with a reading on alleles and how they can result in albinism. Junior geneticists learn to complete Punnett squares and participate in a coin toss simulation of allele pairing. They also learn...
