Unit: Life Science - Survival
Grade Levels: 4-6
Connection To Curriculum: Science, Technology and Engineering
Teacher Prep Time: 1.5 hours
Lesson Time Needed: 8 hours
Keywords: human needs, physical stress, food properties, menu selection, balanced meals, challenges, food web, population, data, ultraviolet radiation, solar, DNA, electromagnetic, solar cycle
(Basic materials are listed. The complete list can be found in each activity.)
String or yarn
Various food samples
Gum drops (five colors)
Candy orange slices
Plain flat toothpicks
Dark-colored construction paper
Sunscreen (five different SPFs)
Students explore and compare the space environment and Earth's environment to determine the resources needed for humans to survive in both environments.
• Describe how a change in a population within a food web can have widespread effects on the other populations there.
• Create a food and activity plan for healthy eating and modify the plan for 17th-century travel and 21st-century space travel.
• Compare the differences in challenges faced by 17th-century and 21st-century explorers.
• Construct a model of a DNA molecule.
• Understand that DNA can be damaged from radiation.
• Investigate the effects of solar UV radiation on an object and analyze the effectiveness of different Sun Protection Factors (SPF).

Lesson Activities and Sequence
Exploration Then and Now - Human Needs
This activity investigates human needs and how humans adapt to new environments. Students experiment to understand the effects of physical stress on muscles. They also identify food properties that make foods suitable for space flight and travel during colonial times. Using the new food-guide pyramid, students create a food and activity plan for healthy eating and then modify this plan based upon what they learn about past and present exploration.
Keywords: environments, human needs, physical stress, food properties, menu selection, balanced meals, challenges
This activity demonstrates to students how changes in a population within a food web will have widespread effects on the other local populations. Page 31
Keywords: food web, local populations, population density
Solar Radiation and SPF Levels
In this activity, students will investigate the effects solar ultra-violet (UV) radiation has on an object or person and to analyze the effectiveness of different Sun Protection Factors (SPF) found in sunscreen products. Page 62
Keywords: solar radiation, ultraviolet radiation, analysis of data, SPF, sun protection factors, suncreen effectiveness, scientific method
Modeling Radiation-Damaged DNA
In this activity, students will use candy (or Styrofoam balls) to construct a model of deoxyribonucleic acid (DNA) and will then alter the model to visualize what happens to DNA when it is damaged by radiation. Page 42
Keywords: solar radiation, DNA, alter DNA, electromagnetic spectrum, molecules, modeling, space weather, radiation applications, radiation levels, doses, ionization, atoms, elements, risks, cosmic radiation, measuring radiation, radiation sources, biological effects, solar cycle
