We’ve accomplished three projects during our Rock Study. We had activities that can identify minerals in the rocks and an activity that familiarizes with the famous monuments and rock formations.
Activity 1: Acid Test
What you need: rock samples, vinegar and bowl.
Drop a rock into the vinegar. If gas bubbles form, then it contains minerals called carbonates.
It’s unfortunate my camera cannot capture the bubbles this rock produces. Mavi was ecstatic when he saw the bubbles coming out!
Activity 2: Specific Gravity Test
What you need: rock samples, weighing scale, notepad and pen, measuring cup/jug, water.
Choose a rock and weigh it. Make a note of its mass (in grams). Fill the measuring cup/jug to 200ml mark with water and carefully place the first rock sample into the water. Look carefully at the scale on the cup/jug to read off the new water level. Make a note of the new level of the water.
By dividing the mass of the sampled rock by its volume gives you its specific gravity.
Activity 3: Modeling Rock Formations
What you need: Playdough/Clay and Rock Formations picture cards
