Experiment ~ Water Density

When I was growing up, I liked science. I had a wonderful Science teacher in junior high and then it went down hill from there. Biology was just okay until dissection started; I loved the hands on work but I still did not have a love for Science. I think the effort that was not put into teaching has a lot to do with my dislike for Science.


When I first started teaching school, I had my heart set on kindergarten and first grade. When I was unexpectedly put into fifth grade, I was heart broken because I could not share a love for Science and Math like I could for History and Grammar.  I taught using the Abeka curriculum and if you have any experience with their Science, then you will understand... I had to get creative with experiments that were not in the book.

Anyway, I knew I was going to have a hard time with Science when it came to teaching Jamie. I am so thankful I don't have to come up with all the experiments that we do but at least what we have worked on makes Science interesting for me.

Today, we experimented with the density of water. We had a good time with this experiment.


Things you'll need:

Salt
Tall glass
1 &1/2 cups water
1 Egg
Spoon
Teaspoon

1. In a tall glass add the water. Gently drop the egg into the water. What does it do? Remove the egg with the spoon; let as much water drip off the egg and spoon in the glass.
2. Add a teaspoon of salt. Stir until the salt is dissolved. Add the egg. What does it do?  Again, remove the egg carefully.
3. Continue with step two until you have added 5-6 teaspoons of salt and the egg begins to behave differently. If you need to continue adding salt do so.



**We began seeing a difference with teaspoon #4 and with #5 and #6 the egg began to do what it is suppose to do. We also added two more teaspoons to watch how quickly they effected the egg.


This experiment was taken from the Apologia  General Science book.

  1. Oh, man. We used Abeka in other areas. Not my favorite. We use Christian Schools International, but with any curriculum, you have to adjust.

    That is a neat experiment. SOOOOO visual and hands-on! Awesome. I did something like that, but with a golf ball for it to be neutrally buoyant. Man, it was a lot of salt! :)

    I torture my students with a pile of floaters, paper clips, washers, wood beads, aluminum foil, and various items to see if they can make an object that has neutral buoyancy. Heee heee. But, it sure does get water every wear! It is good for trial and error!

    You are so much fun! It is awesome that you search and try to make things hands-on. That is so important in science. Most kids get bored with science because many teachers don't know how to do experiments because they can be daunting. I can so understand that- it takes extra planning and sometimes money. I think it is harder to manage and plan than the other subjects. But science and history are my favorite subjects!

    Thank you for sharing! Keep sharing more!!!!! :)

    Love,
