Conducting the Seed Investigation

Seed Investigation - Step-by-step Guide

Example Scenario

One way to kick off the Tomatosphere™ Seed Investigation is by presenting students with a fictional scenario that provides an explanation as to why some tomato seeds might have been exposed to space or space-like conditions.

Tomato Trouble

Flesch-Kincaid reading ease score = 75.1, reading level = grade 6

An Orion spacecraft is heading to Mars. Attached to the outside of the spacecraft are several containers. In the containers are supplies and equipment. The temperature and pressure in the containers is similar those in the spacecraft.

The astronauts suddenly hear an alarm...
