The inverse square law is revealed when your class participates in this activity. They move a graph paper or perfboard square back and forth in a square of light to see how the intensity changes. You will definitely want to add this...

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...

What a fun way to explore Mendelian Genetics! Using a computer connected to the Internet, beginning biologists construct and use Punnett squares of monohybrid crosses to explain how genetic traits are passed to offspring. Other websites...

Looking for a quick, hands-on activity to teach young scientists about Punnett squares through monohybrid crosses? then check out this one.

Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...

Human biology or genetics learners apply their knowledge to a unique situation: two newborn baby girls being possibly switched in the hospital. The engaging activity ends with a Punnett squares assignment in which pupils...

Gregor Mendel was a monk who failed his teaching certification exam. He then dedicated his life to science and ended up creating the field of genetics. This presentation introduces the concepts of genetics and Punnett squares.

Imagine a pair of dragons that produce offspring. What percentage of the hatchlings have wings and large antlers? An engaging activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and...

Hilarious! Use the characters from SpongeBob Square Pants to practice solving genetics problems! Yellow sponge body color is dominant to blue. Square body shape is dominant to round body shape. Did someone switch Mr. Krab's baby...

Students test their knowledge of the Wright brothers by playing "Hollywood Squares." They read (or listen) with comprehension. Students follow the rules as they actively participate in a game to test their reading (or listening)...

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...

Fifth graders examine how traits are passed to their offspring using Punnett Squares. They demonstrate how a Punnett Square works by physically moving around boxes taped on the floor, representing the different traits of chicks and...

Geneticists of the future identify heterozygous and homozygous genotypes, describe phenotypes, and use Punnett squares to solve problems and determine characteristics of offspring. A total of 15 questions make this a compact quiz or...

A two-page instructional activity provides seven Punnett squares for practice in determining genotypes and phenotypes. Each is an example of incomplete dominance or codominance. After your bright biologists have mastered Punnett squares,...

Using plastic Easter eggs to represent parent phenotypes, genetics enthusiasts simulate the passing of alleles. They record the phenotype of each half of the egg, one representing the mother's and one representing the father's. They...

How did scientists determine the cause of illness before technology? Science scholars play the role of medical researcher in an engaging guided inquiry activity. Using observations, technical reading, and Punnett squares, learners...

Students practice completing and analyzing Punnett squares. They create Punnet squares in response to a provided scenario from the company Blue Genes Incorporated. In addition, they complete an activity to determine the phenotype of...

In this genetics learning exercise, students use the Punnett Square to learn about dominance and codominance in inherited traits. This learning exercise has 1 short answer question and 6 problems to solve.

In this heredity worksheet, high schoolers will use a Punnett square showing the mating of a human male and female to answer 4 questions. 2 short answer questions, 2 true or false statements.

Students examine Punnett squares charts and analyze how they are used for successful breeding and predictions of certain traits. They complete interactive Punnett square charts, quizzes, problems, and concentration games.

Students revie the Law of Independent Assortment and Law of Dominance. They practice Punnet squares and predicting genetic outcomes and identify factors that influence heredity.

Young learners view different shapes drawn by the teacher on the board. The teacher identifies each shape by name and discusses the importance of knowing the difference between shapes when building something. The pupils complete the...

Who's your Daddy ... and Mommy for that matter? Given a first-generation group of gummy bear offspring, young scientists must determine which bears are their parents. An activity learning exercise covers the differences in genotypes...

This presentation starts with a review of monohybrid crosses and then explains and offers examples of dihybrid crosses solved with a Punnett square.
