Today we did an activity to learn about how scientists know how to determine where ore mining should take place. Our challenge was to make a two dimensional map of an orebody, based on data obtained by poking a drinking straw through layers of play dough and examining the core which is removed by the [...]
GB and I are learning about rocks and minerals in our Science curriculum. The activity for today was to take two common minerals, calcium carbonate and sodium bicarbonate (basically, tums and baking soda) and make a common, everyday product. By mixing these ingredients with a bit of water you get a toothpaste.
We crushed up the [...]
Today GB and I started a rock study for our science curriculum. We began by boning up on the rock cycle. We studied this, in brief, about two years ago. But I’m hoping to go a little more in depth this go around.
The animated rock cycle at this site was invaluable. Everything was presented so [...]
Today we made the three different kinds of volcanoes and learned a lot about volcano formation and where they are located around the world. I wish you could have seen the light of excitement in GB’s eyes as the volcanoes erupted; especially the stratovolcano. That was very impressive. In fact, he wouldn’t let me clean [...]
When I was at our local craft store I noticed that they had a bargain bin. Digging through it, I found this cool little science kit from the Smithsonian Museum. It’s called ‘Prehistoric Sea Monsters.’ They aren’t really sea monsters, but fossils of these triops (tadpole shrimp) have been found in items dating back to [...]
We played with lots of magnets today. We used a lot of the activities from this site to learn about north and south poles on a magnet, attraction, repelling, and magnetic field.
We also used the magnets that I got in this kit.
First we used the wand to pick up as many paper clips as [...]
