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

Purposeful Packaging

Lesson Plan Grade: 6th-8th

Students will play the role of packaging engineers, exploring how to protect shipped items in innovative ways. Students will use data analysis of consumer surveys to inform the iteration of their materials and designs. Learning Objectives Students will: Design a more sustainable way of packing items for shipment. Collect consumer feedback using surveys. Calculate averages, analyze survey data and evaluate the effectiveness of their design. NGSS Alignment The 3 dimensions… Read more

Simulate Microchip Clean Room Contamination with Crayon Leaf Rubbings

Science Fair Project Idea

Scientific Method

Have you ever made a leaf rubbing or imprint using paper and crayons? What do you think would happen if you got dirt or sand on the leaf? Would it mess up the result? In this project you will find out and learn about how this is related to the process of making the microchips that run our phones, computers, and other electronic devices. Check out this page for more science projects related to this process. Read more

Solar Power

Lesson Plan Grade: 3rd-5th

In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.Engineering Connection Engineers design technologies that can turn sunlight into electricity to power households and businesses. For example,… Read more

NGSS Performance Expectations:

4-PS3-2. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.

You may have heard of the space shuttle Apollo 13, or seen the movie about the amazing survival of the ship’s crew after an explosion aboard the ship. What you may not know, is that duct tape helped save the lives of the Apollo 13 crew! NASA had to figure out a way to keep the 3 crew members alive in a tiny lunar module that was only meant to hold 2 people for 36 hours. They instructed the crew to build life-saving air filters using cardboard, plastic bags, space suit parts and –… Read more

Have you ever seen a superhero movie where the superhero relies on a super-strong material, like Wolverine's adamantium claws, Captain American's vibranium shield, or Iron Man's suit of armor? While scientists and engineers in comic books work on creating fictional materials to help superheroes win the day, real-world scientists and engineers are actually working on super-strong materials that could have a variety of uses, from improved bulletproof vests, to stronger ropes, lighter bikes and… Read more

Talk About a Bad Hair Day!

Science Fair Project Idea

Scientific Method

Did you know that you can make a simple hygrometer (a device for measuring the relative humidity of the air) with hair? Search online for instructions to build one. Does the type of hair used in the hygrometer affect the accuracy of the results? Do some types of hair respond faster than others? Do some types of hair give a larger (or smaller) response? You could get hair samples from classmates, or a local beauty shop. Use hair samples of equal length to construct each hygrometer. To force… Read more

The Viscosity of Motor Oil

Science Fair Project Idea

Scientific Method

The insides of a car engine get very hot when the engine is running. Motor oil lubricates the moving parts, to keep the engine operating smoothly. What happens to motor oil as the engine temperature goes up? Read more

Have you ever wondered how a radio can receive music and news broadcasts over thin air? Radios, as well as radio-controlled cars and cell phones, all receive information via invisible waves. Some of these waves are called radio waves. Radio waves are a type of electromagnetic radiation, a kind of energy that also includes visible light. Radio waves are not harmful but are in fact extremely useful for communicating across long distances. To send information using radio waves, a transmitting… Read more
