Here is a plate tectonic demonstration/lab idea for all grade levels.  You can easily use this video when teaching about earthquakes and plate movements.  All you will need is a hot plate, pan, some milk and chocolate powder.  Place the pan on the hot plate, pour in some milk, pour a thick layer of chocolate powder on top of the milk until the milk is covered.  Turn on the hot plate and then wait a few minutes up to about 5 and you should start to see the "crust" break apart and "magma" rise to the surface.  Extension in your conversation can be:

Note: You will need some fossil examples in order to complete this lab.

In this Google Drawing activity, students will create a concept map using the following words: Earth Science, geology, waves, currents, astronomy, oceanography, stars, volcanoes, planets, meteorology, fossils, weather, climate, rocks galaxies, thunderstorms, tides, tsunamis, lightning, comets, minerals, asteroids, tornadoes, hurricanes, and earthquakes.

In this Earth Science Lab, students will design and experiment that will help them determine the densities of different rocks and minerals. This is a follow up lab to the Phet Density Lab that they would have already completed in my class. You can find the Phet Density Lab in the Educational Resource store. This Rock Density lab however can still be given if you have already discussed how to go about finding mass, volume and densities of rocks and minerals.

In this 3rd through 10th-grade lab, students will observe the formation of salt crystals. Students will also add food coloring to their dissolved salt solution to demonstrate how chemical impurities can change a mineral's color. If you have enough students doing the lab your class will get to see many different results. This Earth Science lab comes with the student work, student image sample results, and with my own insights and explanations as to how the experiment can work well.

In this activity students will determine the type of soil they have as well as figure out the pH level of the soil. Students will reinforce their soil vocabulary in this lab: sand, clay, silt, loam. Students will practice using a soil pyramid.

This Google search activity allows students to go to the internet to search for specific minerals and then to use the Periodic Table to discover what elements the mineral is made out of. This activity usually takes a full 50 minutes for the students to find all of the answers. Students will investigate 12 different minerals and which elements make the mineral up. They will look at a periodic table and decide whether the elements are metals or nonmetals. Students will also search the internet and find out some industrial uses for each mineral.

In this worksheet, students will tell the time by analyzing clock faces as well as drawing clock faces for digital time.  There are nine clocks.  There is also one multiplication review word problem question.

In this reading activity designed for 3rd graders, students will read a couple of paragraphs with 19 missing words.  Students have a word list they get to choose from to fill in the blanks in order to make the sentences sound good and be accurate.  Many of the words come from Saxon Phonics lesson 6 for 3rd grade.

The reading centers around being careful around strangers and the danger there is when talking to them.

In this phonics and spelling worksheet, students are given a list of words that are spelled correctly and incorrectly.  Students then need to circle the correct spelling and then write a complete sentence using the correct spelling.  Phonics rule: ending sounds ck, k, c, or ke
