Adventures in Science

After focusing on history last semester, we are delving into science with a passion.
Last week the children used marshmallows, a styrofoam base, and fettuccini noodles to build structures. Then they made a hypothesis about what type of "quake" it could withstand. They measured the space on the mat, gave the base 6, 3 cm quakes (shakes) and recorded results. They loved the whole experience. It was actually in my 5th graders lesson plan, buy my six year old was right there too. They built several styles of buildings, had multiple quakes, and recorded the data.
My 5th grader read about earthquakes in her book prior to doing the experiments.
Sadly, the Haiti quake occurred just days later. The quake experiment helped my children to have a grasp on what an earthquake is and how it effects people.

This week we simulated an oil spill in a pan of water. The children then used different items to clean the water to see what was most effective. They tried a medicine dropper, paper towels, cotton balls, a spoon, and dish washing detergent. We also read books and looked at photos of oil spills. My 5 year old nephew was visiting that day, so even he got in on the action. The oil spill experiment sparked lots of discussion about how oil spills could effect wildlife and how hard it could be to clean up the environment again.

Yesterday my oldest dissected a crawfish with a friend. Our semester of science is up and running.
