What did you use to weather the starburst in the lab?

Unwrap all the Starburst. Using the grater, weather (shave) each of the different Starbursts onto the paper towel keeping the colors separated. 2. Now, one layer (color) at a time, erode (move) and deposit your weathered Starbursts into foil cupcake liner into a single neat pile of three layers.

How do you make a starburst rock cycle?

STEP 1: Cut one of each color Starburst into fourths to act as sediments. STEP 2: Compact the pile of Starburst sediments together but do not form them, this will act as the Sedimentary Rock. STEP 3: Apply heat and pressure to the “Sedimentary Rock” with your hands or press into a ziplock/Starburst bag.

What is the starburst experiment?

Metamorphic Rock - When you apply heat and pressure to the sedimentary rock, you get a metamorphic rock. To do this, place 8 pieces of starburst candy into a ziplock bag. Push the candy pieces together to create a ball. This will take some time as it needs the heat of your hands and pressure to create.

When you weather the crayon were the shavings the same size or shape as before Why?

No, the shavings were not the same size or shape as before because we broke them down with the penny. The weathering agent was the penny. 3 weathering agents in nature are: water, wind, gravity, ice wedging, plants, etc. Rock sediments erode from gravity, water, wind, animals, etc.

How do you make an edible metamorphic rock?

Metamorphic rocks form from sedimentary or igneous rocks, so this time take half of your sedimentary rock and half of your igneous rock and melt them the same way you did with the igneous rocks. Leave to cool and squash a little bit. This process has demonstrated both heat and pressure. Enjoy your edible rocks!!!

Starburst Rock Cycle Activity

Are rocks edible?

While the practice shouldn't be hidden or stigmatized, Mansbacher said, eating rocks and soil is unhealthy; it can introduce parasites, and rocks can puncture or tear internal tissue, causing bleeding.

What happened to the crayon when cooled?

When you heated up the solid crayons, you caused the crayons to melt. The solid crayons became a liquid and dripped down the paper. As the liquid crayons cooled, they became a solid again.

What type of rock do you think you created in this phase of the crayon journey?

Wax crayons are eroded into sediment, compacted into sedimentary rock, partially melted and pressed into metamorphic rock, and finally melted and cooled into igneous rock.

What do the shavings of the crayons represent?

· Q2: What do the crayon shavings represent? (

Fold the foil over the sediment and press down on the foil (this may be done by stepping on the foil); this process represents lithification – compacting and cementing sediments together.

How do you make sedimentary rocks in the classroom?

How do you make chocolate rocks science?

Squeeze the chocolate into a sphere. Massage the sphere with fingertips until the heat from your fingers begins to melt the surface of the chocolate sphere. The longer and harder you squeeze the stronger the finished rock will be. The heat and pressure change the shape of the rock.

What makes the rock cycle a cycle?

Overview. The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes, over geologic time, change a rock from one type into another. Plate tectonic activity, along with weathering and erosional processes, are responsible for the continued recycling of rocks.

What types of rocks are formed by weathering?

Sedimentary rocks: Rocks that are produced by the action of weathering and erosion that break down pre-existing rocks by physical and chemical processes.

How do you make a metamorphic rock with crayons?

Keep your grater crayons in a pile and fold the wax paper over the top. Apply pressure with the palm of your hand to squish the crayon together. The pressure and heat will form the grated crayons into what is similar to a Metamorphic Rock.

How is a crayon like an igneous rock?

Results: Your crayons have gone through a cycle similar to that of a rock. The crayons start off smooth and hard, convert to broken up pieces when grated and become stuck together in layers when pressed together. After they've been melted and cooled, they should feel hard and smooth again just like the igneous rock.

How do you heat crayons?

What happen to crayon before heating?

Answer. Explanation: 1. Crayon and candle are solid before heating.

When heat is applied to crayons The crayons will melt what change is it?

It has been a long time some I used one. Anyway, physical changes are largely changes in state. Melting, boiling etc. Chemical changes involve the formation of new substances and the making and breaking of strong chemical bonds.

Does obsidian exist?

obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite. Obsidian has a glassy lustre and is slightly harder than window glass.

What will happen if you put rocks in vinegar?

Vinegar, an acid, dissolves bits of a material called calcium carbonate in the limestone. This releases carbon dioxide, a gas that rises to the surface as a stream of bubbles. Rocks that don't contain calcium carbonate won't fizz.
