This edition contains lesson plans about the fundamental concepts, processes, and issues of archaeology, as well as essays for the teacher with detailed information about four periods in North Carolina's ancient history.
- Bouncing bubbles: Students will listen to Bubbles Bubbles by Mercer Mayer and a bubble poem before exploring the joys of bubble blowing. Students will observe bubbles, discuss their observations and create illustrations and stories to share.
- Jack-o-Light: We use pumpkins to demonstrate that fire needs air to burn. This goes really well with Fire Safety Week and our pumpkin unit. Also, we 'guesstimate' how many pumpkin seeds are in the pumpkin. We roast them afterwards by following a recipe. You can also create a Kids Pix picture of pumpkins.

Pre-activities
The teacher will to ask the children to write everything they know about kinds of soil in five minutes. The class shares and makes a class chart.
Activities
Day 1:
- After the class has brainstormed what they know about types of soil, put them in cooperative groups of four. Explain that they will be investigating characteristics of three types of soil: clay, sand and humous. Pass out trays with cups of each type of soil, balance scales, magnifying glasses, hand microscopes, eye droppers, and cups of water.
- Ask the children what they can find out about the soil by just using their senses. Make a class list. Ask the children to brainstorm ways they can use the equipment to explore characteristics of the soil. Make a list of these ways. Add to the class list.
- Ask the children to use the list to explore the characteristics of each type of soil. Make sure that the children talk about how to weigh the same amounts of soil with the gram weights so that they can make a good comparisons. When they use the eye dropper and water, make sure they know to put the same amount of water on the same amount of soil to get a good idea of what happpens with each type of soil.
- Give each group of children time to explore and write about the characteristics of each type of soil. Their observations could be recorded on a Tree Thinking Map. At the end of the investigation time, children may wish to share their findings with the group.
The next day, put the students back into the same cooperative group.
- Have each group take out their Tree Maps from the soil investigations from yesterday. Have them gather around the computer and go to http://ltpwww.gsfc.nasa.gov/globe/pvg/texture1.htm (this site goes on to texture 2, 3, 4 htm.) Children read information and add to their tree maps.
- Ask the students to make a Double Bubble Thinking map (Venn Diagram) to compare two of the soils they investigated. (Or show students how to use a data chart to compare all three types of soil). This will take some thinking and time to come up with good ones.
- Each group should share their Double Bubble Thinking Maps with the class. Use the information from the maps to write a class explanation of the similarities and differences between the three soils.
- Have the children look at the Double Bubble Thinking Maps to create a simile poem about one of the soils.
For example:Sand is. . .as gritty as____________as brown as_____________as heavy as_____________
