Mixtures and solutions are different; one can be separated fairly easily and the other cannot. This hands-on experiment was written specifically for learners with visual impairments or blindness. They will use lemonade and trail mix to...

Twelve compounds are named and each of their chemical formulas are printed on individual cards. Chemistry pupils place each beneath an Ionic or Molecular card, depending on which type of compound is represented.

I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...

Elements, to the rescue! Scholars first review the periodic table, and then learn about the first 20 elements and their properties and uses in the fourth of six lessons in the Mixtures and Solutions unit. Applying their newfound...

We have all heard that we are what you eat, but what are we eating? An informative lesson opens with a discussion of the foods pupils have recently eaten. Then, young scientists perform four experiments on seven...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Energize biologists with colorful images in an activity that captivates the imagination while demystifying the subject of cellular respiration. Participants build comprehension skills and access core content knowledge by analyzing text...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Around the world, about 2/3 of adult humans are lactose intolerant. Scholars work in small groups to discuss a few statements about lactose intolerance. Then, they watch a video on the topic and readdress each statement. Whole-class...

There shouldn't be any accidents with this activity! An inquiry-based lesson has learners explore the absorption properties of the gel compound in diapers. After testing its properties, they learn the science of the molecules that make...

Students investigate bio-fuel. In this investigative lesson, students create bio-fuel from vegetable oil waste. Students will analyze, predict, collect and synthesize data from their experiments with bio-fuel.

Students add borax to a latex polymer and play with it to see the characteristics it now contains. In this polymer lesson plan, students see if it stretches, if it's durable, if the molecules break easily, and more.

In this StudyCard activity, students are asked to describe the geometry and polarity of several molecules and ions. Geometries covered include linear, bent, trigonal planar, trigonal pyramidal, and tetrahedral. Students will need to have...

In this activity, students construct models of molecules using marshmallows and gum drops.

This Study Card stack enables students to review the concepts of matter, the kinds and classes of mater including atoms, molecules, elements, compounds, pure substance, and mixtures.

The page from NASA's The Space Place describes a simple activity, charging a balloon and making it move small pieces of paper. It then goes on to give an excellent explanation of how the activity works, and how it involves ions. This...

This project will teach you the basics of analytical chemistry, which is a must for students who want to go into chemistry or materials science. The molecules in objects we see all around us are constantly attracting each other....
