Student science experiment finds plants won't grow near Wi-Fi router. Five ninth-grade young women from Denmark recently created a science experiment that is causing a stir in the scientific community.
It started with an observation and a question. The girls noticed that if they slept with their mobile phones near their heads at night, they often had difficulty concentrating at school the next day. They wanted to test the effect of a cellphone's radiation on humans, but their school, Hjallerup School in Denmark, did not have the equipment to handle such an experiment. So the girls designed an experiment that would test the effect of cellphone radiation on a plant instead. The students placed six trays filled with Lepidium sativum, a type of garden cress, into a room without radiation, and six trays of the seeds into another room next to two routers that according to the girls' calculations, emitted about the same type of radiation as an ordinary cellphone. Over the next 12 days, the girls observed, measured, weighed and photographed their results. What is A Planet? What is A Planet?
Description What is a planet? The question has been pondered by many since the early Greeks came up with the word “planets.” Since then the number of “planets” in our solar system has fluctuated, sometimes numbering as high as 15, before it was determined that some were actually asteroids. One such celestial object is Pluto, which became the 9th planet in 1930 to much controversy. Much like other sciences, such as Biology, where one may discover a new species, classification is a common and needed process which groups like objects for purposes of comparison and further study.
Using 3D animation, this DVD was created to better illustrate the history behind the discussion defining “What is a Planet?” So come travel with us as we drive along the “Kuiper Belt highway” at 100 mph to explore the far reaches of our solar system and discover how vast our corner of the galaxy really is.

Both the relative size and spacing of the planets are demonstrated in this outdoor exercise, using a mere peppercorn to represent the size of the Earth.

Scientific Method - Mr. Bowen's Fifth Grade. Gummy Bear Science. My kids had a great time experimenting with gummy bears!
We used the "Black Forest" brand of Gummy Bears - results may vary depending on the brand you use. Here is what happened with the Black Forest gummy bears: Gummy bears do some interesting things when put into different liquids. We wanted to find out what would happen when we put gummy bears into water, salt water, vinegar, and baking soda water. We measured 50 mls of each liquid & added 1 tbsp. of salt or baking soda: Here's what our overnight results look like: We recorded length & mass before & after the experiment. My students completed a lab report with 2 charts and 2 graphs for data analysis, here are 3 of the 6 pages: All of the gummy bears GREW due to osmosis.
