The state of molecules is changing. Young actors and actresses perform the process of phase change in front of the class. They assume the roles of water molecules and, as a group, show how the behavior of the molecules in the solid,...

Seeing is believing! Bring DNA to life for young biologists using a simple extraction lab. Individuals extract the DNA from wheat germ, then place it in a microcentrifuge tube for observation. They thread yarn or other material through...

Do polar opposites attract? After an introduction on the polarity of molecules, pupils are asked to design a self-assembling model using materials with different polarity. The challenge should motivate learners to develop a workable...

Sure, your learners know water is made up of two molecules, but watching them separate helps the class see the construction like never before. This resource provides directions on how to build a simple electrolysis device using a...

Of quartz I love geology! The chapter offers five activities at three different levels. It features hands-on activities that cover crystal shapes, cleavage and fracture, hardness scale, specific gravity, and mineral...

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...

Individuals discover how to draw cubes on triangle-dot paper. They use cubes to build structures and draw corresponding isometric drawings on dot paper in the second lesson of the series of five. The activity also introduces the concept...

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...

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...

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

To conclude their examination of forest ecosystems, class members consider the role forests play in the carbon cycle and how forests can offset climate change.

What's in soil? Young scientists study the pH levels of soil from their school yard. They observe the land and area the soil came from to decide if location has anything to do with acidity level.

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...

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...

Class members use an applet on the Internet to simulate the spread of a disease. The simulation allows individuals to determine two nodes to vaccinate to limit the number of nodes infected. By running several simulations, scholars...

[Free Registration/Login Required] Build your own helium atom and make sure it has the correct number of protons, electrons, and neutrons on this site. Site also includes a small quiz on the topic.

In this science activity, you will make a little toy raft that is powered by surface tension, and use your vessel to investigate how surface tension works.

Students work as engineers to learn about the properties of molecules and how they move in 3D space through the use of LEGO MINDSTORMS NXT robotics. They design and build molecular models and use different robotic sensors to control the...

Explore how heat affects the density of air by building and flying a hot air balloon using large plastic bags and the hot air from an electric hairdryer.

In this activity, students use pipe cleaners and foam balls to build a model of a hydrocarbon molecule. They then modify it to demonstrate the chemical reaction that happens when the hydrocarbon is burned.
