Scientific 4th Graders at Edmunds!

Students in Katherine Hiveley’s fourth grades class spent a week in December conducting experiments to test the conditions under which mold grows. The students worked in teams, first, to create a mold terrarium. Then each team had to make a plan of what foods their terrarium would consist of, and decide which conditions they wanted to test. Would their team’s conditions cause mold to grow faster or slower? Some of the team’s variables included darkness, sunlight, salt, vinegar, sugar and more. After a week of recording daily data they came to a conclusion: based on their results, fourth graders concluded that salt was the best way tested to deter mold from growing!
