Back in the 1830s, a young blacksmith from Vermont, made his mark on American history. John Deere, That’s Who! is the story of John Deere and his development of the steel plow. Beautiful illustrations accompany the fun text and bring the story of this remarkable innovator to life.
Apples rot and turn brown because they take in oxygen and give off carbon dioxide. If apples are stored in cool temperatures, they will rot slower than they would in room temperature. Other conditions such as humidity, and the storage atmosphere also effect how quickly apples rot.
Students will discover traits in offspring come from parents and offspring from the same parents have different combinations of traits. This will be done through the analysis of images of two parent plants with completely different traits and 18 offspring plants resulting from the crossing of the two parents. Lesson provided in collaboration with Barleyworld, OSU, barleyworld.org/main/education.
Many students think products simply come from factories or stores. This hands-on activity helps students understand that before an item ever leaves a factory, or enters a store, it began as a resource or product in the natural world – most likely agriculture while also teaching the importance of breakfast and exercise.
This is a two-part lesson that can be done over a week. It begins by using vinegar to dissolve an egg’s shell (dissolution) without breaking the membrane that contains the egg. The shell-less eggs are used in the second part of the experiment to study osmosis, the movement of water across a membrane
Students will explore a foodborne illness outbreak in the role of an Foodborne Illness Investigator (FBII). Using a game simulation, students will determine the type of foodborne illness through the riboprinting of patients and potential contamination sources. Students will then develop their own investigation, identifying a food of their interest and create a safety protocol to prevent potential contaminants.
In this lesson students explore weatherization (physical and chemical) by doing a series of short experiments that demonstrate how rocks and minerals are broken down into soil. Expand this lesson further by taking students on a field trip to look for rocks breaking down into soil.
Explore the production of apples and the process of grafting. Students will be introduced to several varieties of apples and learn that each apple was grafted specifically for its genetic traits and resulting characteristics.
