Tectonic Plates Hands-On Activity 8

Earth Science: Plate Movements, Pangaea

We were still talking about plate tectonics on Friday. We talked about how scientists theorize that the continents were once connected as one giant super-continent, Pangaea. I cut out South America and Africa and asked them to fit them together as best the could. When they didn’t fit together perfectly I asked the kids why the continents wouldn’t match perfectly after 250 million years? We talked about erosion and the...

Earth Science: Plate Movement, Earthquakes

We looked a bit more closely at what happens at fault lines where slight shifts in the crust cause earthquakes. First the kids all made their own layered crust. ED especially enjoyed this! Then we placed an index card in a larger container and created layers on both sides of the paper. We moved the index card back and forth and watched as the grains of rice shifted and moved....

Earth Science: Plate Movements & Earthquakes, Volcanoes and Mountain-Making 16

Earth Science: Plate Movements & Earthquakes, Volcanoes and Mountain-Making

Here’s our hands-on studies of tectonic plate movements, 2nd grade style. We used: a tray with a thin layer of chilled jello (jelly) graham crackers for the earth’s crustal plates colored icing (green-continents and blue-oceans) You can see LD putting the continent and ocean onto his plate (ie. graham cracker). We read about the plates and tectonic plate movement and looked carefully at this map.  We talked about how when...

Earth Science: Layers of the Earth Hands-on Activity 28

Earth Science: Layers of the Earth Hands-on Activity

Just adding this in on Tuesday: I found out today that I have Pneumonia which is why I’ve been feeling ever so lousy. I first saw this activity last year at The Learning Ark. It fit in perfectly with our Earth Science unit. There is also a similar activity using a hard-boiled egg in the book we are using for this unit, How the Earth Works by Michelle O’Brien-Palmer.  One...

Earth Science–The Eight Planets 10

Earth Science–The Eight Planets

 We learned about the eight planets in our Solar System.  While the kids painted with watercolors, I sang this song from the Smithsonian, National Air and Space Museum Website.  It’s called “Family of the Sun” and has one verse describing each of the eight planets (plus Pluto, the dwarf planet).  It’s sung to the Farmer in the Dell:  Here’s the first two verses and the chorus:1)Mercury is hotand Mercury is...

Earth Science — Gravity: the planets, moon and space

Today we had our second earth science lesson.  LD begged to do science again and I always love that enthusiasm! I’m still using  Building Foundations of Scientific Understanding: A Science Curriculum for K-2  (affliliate link) as the basis for some of our lessons. *I read an excerpt about how the earth isn’t the only place with gravity. The moon and other planets have gravity too.  We talked about how people...

Earth Science Unit — Gravity

We have been making slow headway through our Ancient Rome unit, but we needed some new spice added into our homeschool days. We’re off to do a unit on earth science — studying concepts such as gravity, horizontal/vertical, directionality–N,S,E,W, and then moving on to the layers of the earth and the surface of the earth — the “ups and downs, ins and outs” of the landforms and waterforms and how...
