/ 1. Divide students into cooperative learning groups and give each group 4-5 objects to test. Have students create an organizer to predict/test/summarize each material. Set up testing stations at different locations. Students will predict how the matter will react to the different test, and then test each item. Student will record their findings. Each team will choose one item to describe in writing and fellow classmates will try to identify the materials by the description.
2. Students will create a “Matter” book where they will draw pictures or cut pictures from magazines (classify items) unto the three pages of the book labeled “Solids”, “Liquids” and “Gases”.
3. Working in pairs, students will create their own experiment to test and identify properties of five different materials. Share with the class their experiment, procedures and results.
1. Students collect rock samples, or use rock collections from home/school. Conduct research using resources to create a chart for exploration with the properties of minerals.
1. Igneous- Melt chocolate chips and place on aluminum foil. Cool and harden to demonstrate the formation of igneous rocks.
2. Metamorphic- Slice gumdrops different colors Place between wax paper. Apply pressure and body heat to demonstrate the formation of metamorphic rocks. Snickers or other layered candy also works well to demonstrate the change.
3. Sedimentary- Place equal portions of flour, rice, and dried beans in a quart jar. Fill the jar with water and shake. Let the jar settle. Record and observe the layers of sediment as they form.
Sedimentary- Make s’mores to demonstrate the layers in sedimentary rocks
1. Students make salt dough from recipe below. They can bring in items like seashells, rocks, leaves, or plastic bugs to make “fossils” that harden overnight.
Ingredients
1 cup salt
2 cups all purpose flour
1 cup lukewarm water
Directions
1. In a large bowl mix salt and flour.
2. Gradually stir in water. Mix well until it forms a doughy consistency.
3. With your hands form a ball with your dough and kneed it for at least 5 minutes. The longer you kneed your dough the smoother it will be.
Store your salt dough in an air tight container and you will be able to use it for days. You can paint your creations with acrylic paints and seal with varnish or polyurethane spray. You can let your salt dough creations air dry, however salt dough can also be dried in the oven. Bake at 200 F until your creation is dry. The amount of time needed to bake your creations depends on size and thickness; thin flat ornaments may only take 45-60 minutes, thicker creations can take 2-3 hours or more. You can increase your oven temperature to 350 F, your dough will dry faster but it may also brown, which won't matter if you are painting your entire creation (you can also cover your dough in the oven before it turns brown).
There are a few options to color your salt dough: 1. Add powdered tempera paint to your flour, 2. add food coloring or paint to the water before you mix it with the salt/flour, or 3. add natural coloring like instant coffee, cocoa, or curry powder.
1. Make fossils for students to excavate.
1. Mix up the Plaster of Paris according to instructions
2. Place your mold onto a solid surface
3. Pour a little of the plaster mix into the mold
5. Top up with plaster and leave to harden as per instructions
6. Give your little one a few tools and let them get excavating!
Writing Prompt:
1. Research on fossils.
2. After creating fossils, have students write the necessary steps.

### Sand Dunes - Wind

• Have each child wear safety goggles for this activity. Explain to children that sand dunes are formed by the wind blowing sand. Sprinkle a bit of sand in the bottom of a shallow cardboard box. Give each student a short drinking straw and ask him to attempt to blow the sand into a mountain shape. Discuss the time it takes for the wind to create tall sand dunes.
• Use a large sensory table for this activity. Fill the table with damp sand and small rocks. Show children pictures of the Grand Canyon, BryceCanyon, and the Columbia River Gorge. Explain how thousands of years of running water created the deep canyons. Allow children to build a canyon using the wet sand and rock mixture. When children are satisfied with their canyon land form, slowly pour water through the middle of it, creating a canyon and showing the effects the water has on the rock and sand mixture.
• In a sensory table, create a thick mud using potting soil and a little bit of water. Have children create mud hills in the sensory table. Add a few blades of grass if you would like. Place ice cubes at the top of each mud hill and allow them to melt. If children do not have the patience to wait for the ice to melt, use a hairdryer to speed the process along. Have children record their observations of the mud as the ice melts.
