Home Made Compass

We are still working on our electricity and magnetism unit. We just completed a really neat experiment. My little one created her own compass. It was quick, easy, and we had all of the materials here at home. Below what she wrote about the experiment.

Magnet Madness

Today I made my own compass. I filled up a bowl with water. The next step was to take a piece of cardboard or foam and make a float. I took a bar magnet  and slid a needle across the top of the bar magnet . I did it like five or six times. The needle became magnetized and even stuck to the refrigerator. Then, I taped the needle to the foam and put the float in the water. The needle pointed to the North. Then I moved the needle to the West and the needle moved by itself to the north. The needle kept turning to the north. If I know where North is I can always figure out what direction I am going. I never knew that you could make a needle have a magnetic field.

I love the fact that her science has so many hands on experiments. It really helps her to understand the concepts.

Science Fun

Today my little one started the next unit in science. She will be learning about electricity and magnetism. In this unit there is at least one hands on experiment in each lesson. Today she learned about static electricity and did a very simple experiment.
First she blew up a balloon and rubbed a piece of wool on it. Then she had to place the wool next to the balloon and watch what happened. The balloon was attracted to the wool.
For the next part of the experiment she blew up another balloon. This time she rubbed both of the balloons with the wool and then placed them next to each other. The balloons repelled each other.

The next experiment involved magnets. First she placed two magnets on the table with the north poles of the magnets facing each other. The two magnets didn’t want to go together.

Next, she placed the magnets on the table with opposite sides facing each other. (One north pole and one south pole.) This time the magnets were attracted to each other.

 
The lesson learned from these two experiments was, opposite charges attract and like charges repel. She had a lot of fun playing and learning with the magnets and balloons. I have a feeling that this unit of science is going to go very well because she is a hands on learner.

We have finally gotten through the boring parts of science and are onto the fun ones according to my 9 year old. We are working on the third unit, Chemistry of Solutions. She has been learning the difference between mixtures and solutions and solutes and solvents. Every lesson so far has had at least one experiment to go with it and she has enjoyed every bit.

In one lesson she had to mix drink mix, sand, and cooking oil with water to see which ones made a mixture and which ones made a solution.

In another lesson she had to see if different solvents that dissolved in water would dissolve in soapy water, vinegar, alcohol, or cooking oil.

Another experiment she did was to see if whole or crushed sugar cubed dissolved faster and if shaking them or stirring them made them dissolve faster or slower.

A fun experiment she just did was to learn about concentration and dilution. She had to make up some drink mix and poor it into six cups. Then she added water to five of them, a little in the first and a lot in the last. She pored the solutions into ice cube trays and later tasted to see the difference between the regular drink mix and the diluted ones.

She has learned a lot from these experiments and they didn’t take too long or cost too much. Most of the items we had available in our kitchen. In fact, the only things that I had to buy special were the sugar cubes and the drink mix. I like that there are so many hands on lessons to help her learn. She is definitely one that learns by doing not by seeing.
