The need for a respiratory system in humans versus being reliant on gas exchange structures is demonstrated. There are many details about the advantages and disadvantages of each mechanism.  Students are able to learn about the...

Reflection seems simple to understand, but without a complete understanding, pupils struggle with ray diagrams, specular versus diffuse reflection, total internal reflection, and image formation. An engaging interactive provides three...

Create colorful cool or warm butterflies with simple materials. Class members draw their designs, spray the marker to diffuse the colors, and attach pipe cleaners to form the shape of a butterfly with antennae. Individuals must be able...

Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.

Students describe how diffusion occurs within a liquid. They explain a situation where diffusion through a liquid might occur in the natural world.

In this cultural diffusion study guide worksheet, students read a brief overview pertaining to the significance of trade routes and then respond to a reflection question.

Students are given materials with various textures and light sources to investigate specular reflection, diffuse, reflection, angle of incidence, and angle of reflection. Students draw and label an everyday scenario showing specular and...

Students obseve and compare molecular movement within water at various temperatures and of varying salinity. They discuss the movement of water on a larger scale which can affect the movement and concentrations of microbial populations...

Students conduct research and develop a matrix demonstrating the introduction and spread of common household items from 1900 to 2000 in the U.S. They conduct Internet research, watch and discuss a video, and develop the matrix.

Ninth graders begin the lesson by being introduced to the basic terms of economics. In groups, they discover how they are affected by trade because of the clothes they wear and foods they eat. Using primary sources, they examine the...

In this environment worksheet students complete a series of multiple choice and short answer questions on organisms, reproduction, DNA and cell division.

In this diffusion worksheet, students review the terms associated with diffusion and osmosis plus answer questions based on a passive transport lab they completed. This worksheet has 8 short answer questions.

For this gas law worksheet, students learn how Graham's law governs the diffusion of gases. Students calculate the velocity and effusion rate of gases at certain temperatures. This worksheet has 6 problems to solve.

This presentation begins with the many problems multicellular organisms which rely on diffusion encounter. There are many diagrams of mammalian organ structures, and they are labelled with their relevant functions. This an excellent...

Organelles, cellular respiration, ATP, and DNA. The passage attached to this life science reading comprehension worksheet is all about cells. After reading about diffusion and osmosis, kids answer a series of questions based on the text.

Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity: Carbon dioxide gas is more dense than air Bubbles are semipermeable, allowing only carbon dioxide to diffuse...

What role does trust play in diffusing a tense situation? Young social scientists explore trust on a personal and global level during a lesson on peace and conflict. After participating in a trust sit, participants work in groups to...

Two lessons promote social awareness and build relationship skills. In lesson one, scholars define bullying and role-play coping strategies. Lesson two challenges learners to diffuse a bullying situation using their knowledge of...

Students determine how the geographic features of the Silk Road trade route contributed to the economic development and diffusion of culture in both Eastern and Western Civilizations.

In this transport learning exercise, students compare and contrast the characteristics and examples of active transport and passive transport. This learning exercise has 1 graphic organizer and 11 short answer questions.

In this internal systems and regulation instructional activity, learners correctly decide if given statements are true or false. Students apply information learned about the circulatory system to the given statements to determine...

Tenth graders develop a hypothesis and explain what they observed on an activity.  In this investigative lesson students observe osmosis and report their data using a graph. 

Fifth graders investigate the effect of North American colonization on human history. In this colonization activity, 5th graders explore the global impact of colonization of North America. Students investigate the impact of geography on...

In this biology activity, 9th graders describe what osmosis is and how it explains the fact tat a watery syrup forms when you put sugar on strawberries. Then they describe how proteins made by ribosomes leave the cell. Students also...
