In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created. Learners record their data in a table and draw conclusions by...

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height. This activity is a fun way for...

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change. Learners use colored ice cubes, water,...

In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine. This model utilizes Bernoulli's principle to create an area of low air pressure so that ping...

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design. Learners read about several different valves used...

In this activity, learners build their own magnetometer using an empty soda bottle, magnets, laser pointer, and household objects. Once built, learners will use their magnetometer to measure slight...

In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials. Building or disassembling an instrument built from LEGO bricks...

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel. They will then run the gels in an electrophoresis system to separate several...
