Divide the trays into equal areas (one area for each radiation dose), label them accordingly, and sow the seeds that received each radiation dose in their respective area. In 2008, students and teachers, accompanied by two geologists, visited the uranium mines near Nisa, a small town about 200 km north-east of Lisbon. The idea for the project was born when students from several high schools visited Lisbon University for a few days in Summer 2006, and a first trip to uranium mines was organised for them.Teachers and students involved in the project are invited to conduct hands-on experiments and share their results on the projects websitew1 (see graphs below) and during an annual one-day workshop hosted by one of the participating schools.

What is Radiation? - Lesson for Kids: Definition & Examples Other simple experiments using only a Geiger counter involve detecting radiation in salts used in food preparation, such as potassium chloride, and in natural rocks; in more complex experiments, students can place metal plates with different thicknesses and compositions (lead, aluminium) between radioactive material and the Geiger counter, to discover how radiation diminishes when it traverses metal. Global temperature projections with increasing and decreasing greenhouse gas emissions. ePrivacy and GPDR Cookie Consent by CookieConsent.com. Our middle school projects are written and tested by scientists and are specifically created for use by students in the middle school grades. If you are doing it as a demonstration, you'll need one set of materials and graph paper and data tables for each student. Ionising radiation is used to kill all microbes on surgical instruments, sterilising them, and it is also employed in a similar fashion to extend the shelf life of some foods, and even in agriculture, where it is used to eliminate parasites from plant seeds. This project was financed by Cincia Viva, the Portuguese National Agency for Scientific and Technological Culture, the Science and Innovation Program for 2010, and ERDF (European Regional Development Fund). I just love making science click and help kids discover the exciement of experimenting like thisradiation heat transfer experiment. It now involves students (aged 12-18) and teachers from 25 high and middle schools throughout Portugal and the Azores, who receive technical and logistical support from the physics departments at the universities of Lisbon and Beira Interior, and from the Laboratory of Instrumentation and Experimental Particle Physics. We know we can feel heat, but what is heat? A perfect radiating body emits energy in all possible wavelengths, but the wave energies are not emitted equally in all wavelengths; a spectrum will show a distinct maximum in energy at a particular wavelength depending upon the temperature of the radiating body. The wires are red because electricity is flowing through them and heating them up. In our experience, depending on plant species, above 300-400 Gy, most seeds will not germinate, and those that do germinate have serious problems, for example they rot after only a few days. For a class demonstration or for each team of students: Have students design and conduct their own research into the influence of surfaces on temperature comparing Earth surfaces that interest them (such as colored soils, dry and wet soils, grass, dry leaves, or different types of coverings such as plastic or aluminum foil). An object with high albedo reflects the majority of the radiation while an object with low albedo reflects only a small amount of incoming radiation but absorbs the majority of the radiation. Each one is a source of radiation to some degree. It is such a fun and engaging activity for my students, especially during distance learning. In addition to student graphs and captions and participating in discussion, you may choose to have students respond to the discussion questions in their science notebook and submit it for evaluation or have students predict the heating and cooling curves of other types of materials and justify their predictions. 7 LinkedIn 3 Twitter 4 Facebook 5 RSS @ Instagram 0 Pinterest 9 YouTube 6 Vimeo. About 43% of the total radiant energy emitted from the Sun is in the visible parts of the spectrum. Discovery opens new routes to combat spore . Looking for lots more fun, science experiments for kids? All rights reserved. The Environmental radiation project also provides extracurricular activities. Carmen Oliveira is a physics and chemistry teacher at Casquilhos High School in Barreiro, near Lisbon. Note that this experiment uses materials to model sunshine and Earth materials. Develop an interactive workshop where teams, representing various countries shall develop solutions for addressing the fuel cycle needs of the country they represent, as well as those from other developing countries. Have you ever walked on a sidewalk in the summertime in bare feet? At the end of this day, there is a pros and cons debate between the students and guest scientists concerning radiation issues. Look inside the toaster.. Do you see the red wires? STAY CONNECTED. You can order classroom materials and request reproduction rights for printed materials. (The oil acts as a sealant and keeps the air trapped inside the bottle).
