Small and large are relative terms; what's the best way to quantify them? Young scientists take on that challenge as they complete an interactive activity to explore size. They build structures during their exploration and begin using...

Provide young biologists with everything they need to excel in the study of lymphatics, the nervous system, hormones, cellular division, and more! Pupils utilize the workbook, complete with end-of-chapter assessment worksheets, to...

Compare sizes of microscopic items. Given a set of labels of microscopic objects, pupils try to place them in order from smallest to largest. Scholars then compare their lists to the actual comparisons along with the measurements of the...

Young scientists grab their measuring tapes, rulers, and yard sticks as they see how big Arctic animals really are. To conceptualize the trait of height or length, each small group will measure out the entire length of an arctic animal....

Young scholars sort and compare/contrast the lengths of various whales. They sort pictures of whales in order of smallest to largest, and given a rope marked with the lengths of the whales, they compare the actual lengths of the whales.

Elementary learners listen to a story, then sort objects from largest to smallest at six different stations around the classroom. Adaptable for a large range of age and ability groups. 

So, this is not technically a worksheet, but rather a chapter of reading material, pictures, and diagrams introducing young biologists to the cell. Cell theory, diversity, size, and shape are described. The internal organization and...

Students recognize and categorize different bodies of water. For this watershed and water environments lesson, students "Follow the Water from Brook to Ocean." Students define the different bodies of water and sort from smallest to...

Whales are all big, but some are larger than others! Kids will love sorting the 10 whale species by size at their desk (whale cut-outs provided). Next, use a whale rope to visualize how long each of these whales actually is. A large...

Extreme characteristics can create some unusual mammals. Learners flip through a slide show of some of the most interesting mammals that are both living and extinct. Implement as a remote learning resource or use in-class to review...

A small little ant can have a large impact on its ecosystem. Young researchers explore the different species that live in a plains ecosystem. They find the characteristics of several species and then compare species to determine how...

Can a horse pull more than its weight? A simple simulation answers this question and more. Pupils adjust the mass in a cart, the mass of the horse, the acceleration of the horse, and the angle of the tension rope between the horse and...

Physical or earth scientists construct this clever contraption to demonstrate how size effects frequency. Several paper rings of various sizes are taped onto a board and shaken to create vibrations. The resonant frequencies are easily...

Learners explore fossils by participating in an in class experiment. In this archaeology lesson, students utilize dough and classroom objects to create fossil imprints after hiding the toy/fossil in the dough egg. Learners categorize the...

Students discover the different shapes and sizes of rocks. They create a chart on what they already know about rocks and sort rocks by size. They place cutouts of rocks on construction paper from smallest to largest.

Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.

From tiny organisms to entire biomes, young scientists examine the interdependent relationships tying all living and non-living things together with this collection of ecology resources.

Your introductory lesson to oceanography can be outlined with this apropos presentation. It touches on the physical features of the ocean floor, waves, tides, and currents. One small issue is that some of the graphics are not of the...

In this scale worksheet, students use the SI system to compare the sizes of some of the smallest and largest organisms on Earth. This worksheet has 7 problems to solve.

In this lunar crater worksheet, learners use an image taken by the Lunar Orbiter spacecraft to find the scale of the image and determine the diameter of the lunar crater Tycho. They also find the size of the smallest and largest features...

In this Solar System worksheet, learners compare the size of 8 planets to Earth as they complete the graphic organizer. Students also respond to 3 short answer questions.

In this science worksheet, students select 24 of the dinosaur names from the list and write them in the spaces on the bingo card. They match each of the dinosaurs listed to their correct description.

Young scholars examine the surface area to volume ratio and how they relate.  In this surface area lesson students complete several activities.
