Pupils explore the gene frequency in Hardy-Weinberg Equilibrium experiments. They inquire into the studies of both black and gray squirrels. Basically the population genetics of certain squirrel populations. The species of each are...

In this president survey learning exercise, students are given a tally chart. The question at the top is "Who is your favorite president?" Students have room to list the responses, and tally them up. No choices are given.

In this language arts worksheet, students analyze 100 "jumbled" words and write them correctly. These are high frequency sight words.

In this tally chart learning exercise, 1st graders use tally marks to count. Students count the number of stars in each row, keeping a running tally beside each grouping.

In this tally chart worksheet, 1st graders use tally marks to count. Students count the number of pumpkins in each row, keeping a running tally beside each grouping.

In this histograms worksheet, students use the bar graph histogram to answer questions 1-4 and the tally chart for question 5. Students finish with two test prep questions.

In this data display instructional activity, students solve 4 problems in which data on a tally chart and pictograph are analyzed. Students use this information to solve the problems.

In this spelling worksheet, students learn to spell a list of 7 words. All words are high frequency sight words. Students write each word one time on the lines. There are additional at-home spelling activities listed.

Pupils identify and interpret sound as a vibration and what period and frequency are. They also divide the various types of objects so that all objects are explored and the procedures are determined by the students. Finally, pupils...

In this Working with Frequency Tables activity, students analyze data that is organized in simple frequency charts.  They calculate average from data presented in a frequency table, calculate a cumulative score, and identify data...

In this high frequency words instructional activity, students alphabetize the words: bone, box, draw and pictures, then use the words in a sentence and color code by consonants and vowels.

Young seismologists learn more about plate tectonics with a set of pre-lab, lab, and post-lab lessons plans on earthquakes. After exploring how waves travel through various materials, sixth graders record their observations and...

In this sound worksheet, students read about sound waves, how they are graphed, what frequency is and how it's related to pitch and the speed of sound. Students solve 8 sections of problems including matching terms related to sound to...

In this sound worksheet, students understand how sound is created and how the human ear "hears." Students compare the frequency, amplitude, and speed of sound. Then students complete 10 matching, 7 fill in the blank, and 11 short answer...

In this Benford's Law learning exercise, high schoolers read about the first digit frequency of numbers. Students solve 3 problems about sunspot numbers, solar wind magnetism and the depth of the latest earthquakes by using on line sites...

In this statistics and probability worksheet, students analyze frequency distribution tables or histograms and box and whisker plots.  The two page worksheet contains four multiple choice questions.  Answers are included. 

High schoolers define amplitude, wavelength, frequency, and period, calculate period given frequency, and calculate frequency given period, define crest and trough and locate both on diagram of wave, differentiate between latitudinal and...

In this flower population activity, students use a diagram of first and second generations of a flower population to complete 2 short answer questions about genotype and allelic frequency.

In this characteristics of waves worksheet, students answer 9 questions about the structure of waves, the types of waves and the components of waves. They describe the frequency of a wave and calculate the velocity and frequency of waves.

Young scholars use water filled pipes to play a tune and consider the mathematics behind the sound waves. In this sound wave lesson, students play a tune with water filled pipes. They create a mathematical model to evaluate the...

In this histograms worksheet, learners solve 9 short answer, multiple choice, and graphing problems. Students construct frequency tables and histograms of data.

Students discover every pendulum has a natural vibration cycle that depends on its length.  In this physical science lesson, students participate in an experiment that shows the natural vibration frequency of two pendulums is the...

Students answer questions related to the calendar and the weather.  In this past tense and adverbs of frequency lesson, students use past tense verbs and adverbs of frequency to answer questions about the weather and the calendar.

High schoolers explore uniform circular motion, and the relation of its frequency of N revolutions/sec with the peripheral velocity v and with the rotation period T, and the "centripetal acceleration" of an object.
