Elementary schoolers count and order objects using numbers 1-300. They bring recyclable items from home. Students group the items, skip count by 2's, 3's, and 5's, and arrange the items on a number line. Recyclable plastic bags are put...

Students estimate the distance of student's broad jumps. This activity can take place in the block center with a small group of students. They are explained that they are going to jump from a starting point (marked with the masking...

Estimate and explore the length and weight of classroom items using standard measurement and scales. Students will work in groups to determine appropriate measuring tools, weigh or measure items, and record their results on a data chart....

Students observe how math is important in navigation and engineering. They study how surveyors use math and science to calcute, count, measure, label, and indicate distances on a map. They estimate specific distances.

Help learners discover methods to estimate animal population. They will participate in a simulation of catching and tagging fish in order to estimate the fish population. They scoop and count goldfish crackers, record data, and use...

In an introductory lesson, youngsters take a pre-assessment quiz, get a grasp of a gram of mass, and then estimate the mass of microorganisms that live within a human body. Using Glo Germ™, a material that allows you to simulate the...

Ninth graders produce a projected, pinhole image of the sun and from measurement of the image and projection distance, calculate the actual size of the sun. They estimate the sun's apparent brightness from different planet.

How many of your students know that even today new species are being found all over the globe? Introduce them to the amazing diversity our planet houses with a creative activity about animal variation and classification. They'll use a...

Although the worksheet for the lab activity is not included, this is an activating activity for your class to do when learning about the greenhouse effect. They lay three thermometers underneath a lamp: one out in the open, one under a...

Students study water conservation. In this water conservation lesson plan, students investigate the scarcity of water and determine reasons for conserving water.  Students estimate how much water they use in one day and identify...

Most species of animals include a variety of fur or hair color, but why? Scholars watch a video about a changing environment for mice. As the rocks around them change hues, different colors of mice begin to thrive. Discussion questions...

Students are introduced to the solar system and its place in the universe. They begin to grasp the idea of very large numbers by estimating and computing how long it take the class to make a million x's.

After a whole-class discussion of water reservoirs, ten liters of water are given to each lab group to represent Earth's total amount of water. They divide the water into smaller containers, each representing one of those reservoirs. The...

Students work together to build models of prairie plants. Using the model, they estimate the height and then measure them using metric and standard units. They write a fraction to represent their part of the whole set and compare and...

In this solutions worksheet, students calculate the pH of given solutions. Students determine the equation used to determine pH and the estimated pH for mixtures. This worksheet has 12 fill in the blank and 15 problems to solve.

Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson. 

Learners discover how fish tagging is used by marine biologists and fisheries to estimate fish populations. Participating in a simulation, students use estimation to determine the whole population from a small number of items.

Young scholars practice using their estimation skills by utilizing apples.  In this percentage lesson plan, students utilize a scale and an apple to discover the percentage of each bite they take.  Young scholars share their...

Students apply their math skills to develop an accurate estimate of the height of a tall tree. Three different methods are outlined. All grade levels should be able to perform the shadow method and the proportional method.

Students collect, organize by table, and examine census data in a simulation, estimate the size of the population in the simulation and make predictions based on the collection of census simulation data.

Students understand that temperatures in Alaska can be negative numbers. In this temperature lesson, students recognize the temperatures above and below zero. Students compare temperatures using the greater than and less than signs....

Students examine basic facts about the anaconda. They discuss the length of an anaconda, estimate the length of 33 feet, compare their estimate to the actual length, and decorate the paper snake with colored scales.

Students examine and compare traits of humans and crocodiles.  In this crocodile lesson students use a ratio to estimate the height of a person and compare that to a crocodile. 

In this random sampling worksheet, students compare data collected by a random sample to data collected by an actual count using pieces of paper with numbers written on them. They compare their data for the actual count to the random...
