Chemistry aces apply the criss-cross method for finding the formulae of binary compounds. Using aluminum chloride and magnesium oxide as examples, they are guided step-by-step through the process. This is a concise demonstration of this...

Students use this following the study of pedigree designs and human genetics. Four pedigree designs are prepared of your (student's) family's genetics. They construct the pedigree representing two, three, or four generations.

Students use analogies to show the relationships among cell, nucleus, genes, chromosome, ribosome, replication, mitosis, transcription, translation, DNA, RNA, amino acids and proteins, genotype, phenotype, and genetics vs. environmental...

In this science worksheet, students use basic scientific concepts to complete the series of puzzles that are intended to increase science literacy about some of the common vocabulary used for the study of the universe.

In this evolution of the stars worksheet, students are given 12 sentences and they choose from one of two terms to complete the sentences. They use a given diagram showing stars, their absolute magnitude and their spectral class.

For this chemistry worksheet, students calculate the eigenfunction of the operator. They use the operator matrices. There are 4 questions.  

A somewhat amusing assignment, this instructional activity lists statements that an ancient organism may have made and asks learners to determine what geologic era that each may have lived in. It uses witty word puzzles and...

Students brainstorm a list of inventions that have affected their lives. In groups, they use the internet to research a specific inventor and their invention. They use the information to write two paragraphs and share their information...

Young scholars use cartesian coordinates (x,y,z) in 3-dimensional space. [Optional: appreciate there exist two ways of defining the z axis, and which of them is used.] They become familiar with the tools and terms used by surveyors.

Learners study the constellations fo the Big Dipper and Cassiopeia and their use in finding the Pole Star. They realize that other celestial objects--Sun, Moon and planets--share the rotation (and hence rise and set), even though their...

In this chemistry worksheet, students measure the different vibration levels of energy. They use the fundamental vibration frequency formula to calculate the Morse potential for a given chemical bond. There are 2 questions.

In this ionic compounds worksheet, learners complete two tables with the chemical formulas given the cations and anions that bond.

In this compounds activity, high schoolers write the chemical formulas for ionic compounds given cations and anions. They are also given cations and anions and identify the number of cations and anions needed to write...

First graders watch a video about the seasons. They role play with the teacher the sun and earth. The student's heads are the earth, their foreheads are the Northern Hemisphere. The teacher shines a flashlight on them to simulate the sun...

An online resource, this worksheet has your chemistry learners complete four data tables with information about atoms and chemical bonds. The first table addresses atomic number and mass, as well as numbers of protons, neutrons, and...

Students investigate the study of pedigree designs and human genetics. They construct the pedigree representing two, three, or four generations. They investigate their family members' traits for ear lobe attachment, tongue rolling,...

For this environmental worksheet, learners will read 2 different situations and decide whether it's an example of reducing, reusing, or recycling. Then students will give short answers to 3 questions.

Students create their own baby pets based on the genes of the two parents.
