English language development lessons are brought to you in poems, picture cards, and grand discussions in a We Can Do It! themed unit. Topics of discussion include daily challenges, parts of a whole, words that describe what we...

Objects are larger (or smaller) than they appear! Scholars use a laboratory investigation to explore the difference between resolution and magnification. The activity allows them to calculate the size of the field of view of their light...

Investigate the life of Mahatma Gandhi by researching non-violent lifestyles. Learners define the word ahimsa and discuss the personal characteristics that made Gandhi a peaceful warrior. They also create a poster about the story "The...

Students evaluate snack foods based on calories and fat. In small groups, they use this information to make informed and wise food choices. Students graphically represent the fat in a food by measuring the equivalent of the food fat with...

Linear measurement is the focus of this math lesson. Youngsters work in groups to build towers with blocks. They build towers represented on index cards and determine how many blocks taller one tower is.

Discover the effectiveness of wind, water, and steam as energy sources. The hands-on activity has young scientists create a turbine from common materials. After constructing the turbines, they use wind, water, and steam to turn them and...

Pupils analyze a pattern of conference tables to determine the number of tables needed and the number of people that can be seated for a given size. Individuals develop general formulas for the two growing number patterns and...

Visual models are a great tool for demonstrating the concept of equivalent fractions. Given two pictures, young mathematicians first identify each fraction and then write an explanation for why they are equivalent. Use as a guided...

Let your class bounce to examine the concept elastic potential energy. Individuals bounce on a pogo stick in order to calculate its elastic potential energy. Groups then compare the elastic potential energy to the gravitational...

Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

Get your scholars cooking with a collection of activities that pairs the class to a community chef, promotes healthy snacking and drinking, and explores fruits and vegetables. Lower elementary learners...

Launch a lesson that's sure to capture middle schoolers' interest! Exploration enthusiasts examine the planets of our solar system using an activity from PBS's Space series. The resource includes images and information for each planet,...

Show learners how to use simulations and random sampling to reach conclusions with the last resource in a 25-part series. The assessment contains three scenarios, each with several parts, and covers comparing populations using...

Thorough explanations of the trends in the periodic table of elements make up the majority of this handout. Atomic and ionic size, ionization energy, electron affinity, and electronegativity are presented before giving chemistry...

Not novel, but fun, this lesson gets your space science learners to model the size of the planets and the solar system along your school's hallway. Scaled measurements as well as actual distances are provided for both planet diameters...

Students carry out a cost analysis. In this comparative math instructional activity, students compare the cost of equal measures of gasoline to mouthwash, house paint, fruit juice, white-out, and other liquids.

Learners predict and test different items to see if they sink or float. In this sink and float lesson plan, students predict whether an item is buoyant or not, and learn that size and weight do not matter when it comes to buoyancy.

Rather than a worksheet, this teacher resource is a one-page, scripted answer sheet for a guided lesson on length word problems. First graders are asked to compare the length of a flower and a jar of jam with a number of unit boxes....

Learners explore all the different sizes of feet within their age range while exercising their graphing skills. They work in teams to survey children in their grade to gather data about the different range of shoe sizes. Each group then...

Students consider the comparative sizes of the planets in the solar system. In this scale lesson, students select balls of different sizes to represent the planets in the solar system.

A big caterpillar, a little caterpillar. A big butterfly, a little butterfly. Images from Eric Carle's The Very Hungry Caterpillar model for learners with autism the difference between big and little.

Students differentiate the pros and cons of different areas. For this geometry lesson, students compare and contrast different sizes based on their area. They put an image to the size of a shape.

Learners learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students explore craters that objects of different sizes and weights (marbles, Ping-Pong balls, and aluminum foil balls) create.

Learners create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and...
