Coming up with new ideas is hard! How do engineers design new things or improve existing ones? Engineers and inventors use different brainstorming techniques to help them think outside the box and come up with new ideas. In this lesson plan, your students will practice brainstorming with a method called SCAMPER. Read more

In this lesson, students are challenged to design and build a controlled-release tablet, which will be made from different colored bath tablets and a variety of water-soluble plastics. First, they will have to test the properties of each of the different plastic materials. Then their task will be to create a tablet that releases three different colors, each at a pre-determined time after the tablet has been submerged in water. As students design and build their controlled-release tablets, they… Read more

NGSS Performance Expectations:

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-ETS1-3. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.

Need Help Getting Out of a Sticky Situation?

Science Fair Project Idea

Scientific Method

Does adhesive tape hang tight at different temperatures? Measure the adhesive strength of tape at both low and high temperatures. To raise the temperature, we suggest using a blow dryer at both low and high heat settings. To lower the temperature, use an ice pack (try to keep condensation from forming on the tape and confounding the results). For even lower temperatures you could try "dry ice" (frozen carbon dioxide), if available. (Wear heavy gloves when handling dry ice, because it can… Read more

Polymer Permeability: Which Plastic Wrap Prevents Oxidation Best?

Science Fair Project Idea

Scientific Method

There are currently two different kinds of polymers used for kitchen plastic wrap: low density polyethylene (LDPE) (e.g. Saran or Glad Wrap) and polyvinyl chloride (PVC) (e.g. Reynolds PVC Foodservice Wrap or Boardwalk PVC Food Wrap Film). Which of these materials is less permeable to oxygen? When you slice an apple, the surface of the slice turns brown as the apple is oxidized. Can plastic wrap seal out oxygen and prevent the apple from browning? Which plastic wrap works best? Do… Read more

Stressed Out? Take a Break with this Project!

Science Fair Project Idea

Scientific Method

Is an I-beam as strong as a solid beam of the same size? What if you include weight in the comparison: which beam has the greater strength-to-weight ratio? Would an I-beam be stronger than a solid rectangular beam of the same weight? What about other structural shapes (e.g., T-beams, U-beams)? In this project you can find out by setting up a test stand, putting on your safety goggles and measuring how much stress these building components can handle before they snap. Read more

Wood Adhesive Durability

Science Fair Project Idea

Scientific Method

The different species of wood used in construction offer a variety of challenges based on density, porosity, oils in the wood, flexibility, elasticity, etc. The intended use, e.g., structural or cosmetic, presents different challenges as well. The glue must be compatible with the wood, the use, and the climate, so many experiments are possible. For example, you could design an experiment to test the durability of different adhesives using the same wood. Or, you could try different wood… Read more

Cultures around the world have developed knots for many uses. For example, the Inca people used knotted cords called Quipu for collecting data, keeping calendars, and even military organization. In Japan, knots are used in celebrations, food prep, and garments. Elaborate paper Mizuhiki ones, such as the examples in this activity are tied to mark important life events. Educators, a lesson plan is also available for this topic. Read more
