Students examine elastomeric polymers in a lab activity in which they design a bungee cord. Students must determine the tensile strength, percent elongation, and plot stress versus strain graphs for their experiments on rubber bands...

Students develop a comprehension of parts per million as a concept. They work in teams to create successive dilutions of a solution to reach a parts-per-million concentration. Students list what they think the atmosphere is made of. They...

Students explore ways to use indicators to distinguish between acids and bases. They conduct an experiment to model and discuss the harmful effect of acid rain in our living and non-living environment.

Fifth graders inspect the basic functions of the immune system and determine how viruses and bacteria invade the immune system. They also explore what happens to the immune system in outer space.

Students study the parts of the human respiratory system while examining the gas exchange that takes place in the lungs. They make a model lung. They look at how the respiratory system is affected by spaceflight.

Students investigate how animals adapt to use its senses to identify foods that are nutritious or noxious. They determine how they associate foods with other things such as birthdays. They discuss the role of the nervous system in the...

Young scholars conduct an experiment to determine the percentage of sugar in various types of gum. They weigh the gum after chewing it to determine the amount of mass lost from each piece of gum, analyze the data, and create a graph of...

Students use vector analysis to examine the concept of dead reckoning. They listen to a teacher-led lecture, complete a Vector Voyage Worksheet with the teacher, answer discussion questions, and use the Pythagorean Theorem for speed...

Students conduct a simple test to determine how many drops of water, rubbing alcohol and vegetable oil can be placed on a penny before spilling over. They consider how varying surface tensions allow for different amounts of each liquid...

Students study about chromatography, a process used to separate mixtures. They see that chromatography is used to detect, separate or purify different substances. This nice instructional activity results in a beautiful t-shirt for each...

Students are introduced to the properties of solids, liquids and gases. They see that colloids are mixtures which display the properties of more than one of these states. They engage in an excellent experiment which demonstrates this fact.

Students illustrate the changes in the properties of a material at its glass transition point. They gather data which they use to construct graphs regarding elastic modules versus absorption modulus, tangent delta, and the effect of...

In a comprehensive role playing activity, teens play the parts of different stakeholders in the realm of acidic oceans. They research, debate, and create a presentation from the perspective of either ocean organisms, the fishing...

Investigate thermoset polymers through experimentation. In an effort to determine the strongest, most flexible mixture, groups conduct an experiment on different-ratio epoxy-amine polymers to finish the set of two lessons.

Students experiment with the concepts of surface tension. They participate in a number of different experiments that introduce them to surface tension. They work in a small group in order to conduct these experiments.

Learners study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Plop, plop, fizz, fizz, oh that one is the fastest. The teacher demonstration is the second part of a four-part series. The class observes how different pill types dissolve in simulated stomach acid. They determine which one dissolves...

Newton's Laws get the rocket to work, but do they serve any other functions? A six-page resource classifies rockets by the type of propellant they use. It then describes applications of Newton's Laws of Motion, both in the...

You can breathe easily now that you've found a winning resource. Young biologists learn about the process of cellular respiration, primarily through teacher-led discussion and instruction. They also consider the concept of...

Mix it up by using an intriguing resource that teaches young metallurgists that alloys are a metal mixture. They learn about the advantages of using alloys over pure metals and investigate titanium alloys as an example to finish the...

Did you know that there are over 200 different types of cells in the human body? One type, the stem cell, is the focus of the fifth of six installments in the Cells unit. The lesson asks the class to discuss stem cells and their...

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.

A PowerPoint presents features of polymers and two of its categories (thermoplastics and thermosets). Instructors conduct demonstrations to illustrate the Weissenberg Effect and the Barus & Kaye Effects of polymers in the first...

What energy conversions occur in the operation of a device? Small groups investigate devices and the energy conversions that occur. The groups create energy flow diagrams with added conversion processes for each of the devices...
