Explore the role of pore size in the diffusion of a substance across a membrane. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion. Diffusion is always happening, even when a system appears to have reached equilibrium, because molecules are always moving. Cells are selectively permeable, meaning that their membranes allow some substances to cross easily while others are unable to cross without assistance. Cell membranes are selectively permeable, in part because its pores are small, allowing the cell to prevent larger molecules from moving across the membrane.

Movement of ions in and out of cells is crucial to maintaining homeostasis within the body and ensuring that biological functions run properly. The natural movement of molecules due to collisions is called diffusion. Several factors affect diffusion rate: concentration, surface area, and molecular pumps. This activity demonstrates diffusion, osmosis, and active transport through 12 interactive models.

This minds-on analysis and discussion activity helps students understand that cell size is limited by the very slow rate of diffusion over any substantial distance and the insufficient surface-area-to-volume ratio for larger cells. In addition, students calculate why these problems do not apply to long slender cells or parts of cells (e.g. the axons of neurons that extend from your spinal cord to your foot). To maximize student participation and learning, I recommend that you have your students complete the questions individually or in pairs and then have a whole class discussion.

Explore the role of a molecule's mass with respect to its diffusion rate. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion. Diffusion is always happening, even when a system appears to have reached equilibrium, because molecules are always moving. Massive molecules have more kinetic energy than less massive molecules at the same temperature.

Explore the role of temperature in the rate of diffusion of a substance. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion. Diffusion is always happening, even when a system appears to have reached equilibrium, because molecules are always moving. When molecules are heated, they move faster.

The learner will begin a timeline of famous Virginians which will be ongoing using paintings from the Virginia Museum of History and Culture. Students will learn to cite digital images correctly.

Students will use an article from Education World to determine appropriate and inappropriate uses of technology in school.

The student will use the present mode in slides to play a game about digital citizenship and good social media choices individually or in small groups (or with partners). 

This lesson allows students to create a slideshow presentation about digital citizenship. The slideshow will focus on interacting with others online.This lesson involves the design process witht the creation of a slideshow. Students will choose from a list of Digital Citizen rules to focus on in their slideshow.Focus on concepts such as :Being Polite, Following Website Rules, Staying Positive, Being Respectful are to be included in the slideshow.Each slideshow should include a title slde and at least 4 additional slides. 

K-12 resources with links to specific lessons in Common Sense (commonsense.org) with a Seesaw lesson as well if your elementary school uses Seesaw as an LMS.

The student will cut and paste or match-up vocabulary words and definitions digitally using Google Slides.  The six terms in this set are Digital Balance, Unplug, Social Media, Digital Fatigue, Media, and Digital Citizen.

This section includes recorded and archived webinars on the topics of digital citizenship, internet safety, parenting around technology and other related topics. For new free webinars and additional recordings see Digital Respons-Ability's website.

In this activity, students create digital flashcards to review DNA content (guiding study questions and key are provided). Students can use full-screen mode with the document to quiz his/herself with the flashcards.

Digital History projects are "an approach to examining and representing the past that works with the new communication technologies of the computer, the internet, and software systems.” As of March 2024 there are over 80 projects in the Hub related to World History, US History, Geography, Economics, and Gov./Civics.

We hope you use, share, and send new projects we can add to the hub!

 Objectives: Students will be able to identify hidden images in visual media. Students will identify themes in images.Students will identify supportive evidence in images.Students will identify if the image is a fact or opinion, persuasive, or informational. Students will be able to identify encoded messages in visual images. Students will be able to identify a creative practice to reflect on hidden meanings in visual images.

Collaborate with a dance class of the same age group from another country or location through video conferencing media.

Student-Designed Themed Virtual Art Exhibition. Students will design a virtual exhibition based on a theme of concept and develop criteria for curating works to include in the exhibition.
