There are a variety of equipment sets that could be useful for an Earth science exploration activity, depending on the specific goals of the activity and the age and skill level of the participants. Here are a few suggestions:
Rock and mineral identification kit: This could include a variety of rock and mineral samples, as well as tools such as a geologist's hammer, a hand lens, and a streak plate.
Soil sampling kit: This could include soil sampling tools such as a soil auger or a soil probe, as well as sample bags or containers for collecting and labeling soil samples.
Water quality testing kit: This could include basic water quality testing equipment such as a pH meter, a dissolved oxygen meter, and a conductivity meter.
Weather monitoring equipment: This could include basic weather monitoring equipment such as a thermometer, a barometer, and a wind speed/direction meter.
GPS units and compasses: These could be used for navigation and mapping purposes, and could be particularly useful for more advanced exploration activities.
Field notebooks and data collection tools: These could include pencils, rulers, and other tools for collecting and recording data in the field.
Safety equipment: Depending on the nature of the exploration activity, safety equipment such as hard hats, safety glasses, and first aid kits may be necessary.
It's important to ensure that any equipment used in an Earth science exploration activity is appropriate for the age and skill level of the participants, and that safety is always a top priority.
