More Science Experiments by Rus

Hi. I am Rus. I am going to talk about the experiments. There is one that I want to tell you about first. We put a pin in a bowl of water with toilet paper. The surface tension made the pin float. The molecules in the water stay together and that blanket that they make makes the pin float. There was another experiment. We made something that is neither a solid or a liquid called non-Newtonian fluid. It turns to a solid when pressure is put against it. We made this with corn starch and water. The last one we made is sorbet. We put in ice and salt water in one bag and orange juice in the bag inside the other bag. Why use salt? It lowers the freezing temperature so that the juice would turn into sorbet. Then we shook it. Then we had sorbet.    

Science Experiments by Rus - Fun with Chemistry and Physics

   We have had a great summer, but now it is the school season and time to begin some science. It is fun to do the science course called "Exploring Creation with Chemistry and Physics." We are learning about chemistry and physics. We have already done a lot of fun things. We are learning about buoyancy, and we made boats for one project. We made some out of tin-foil, and we put coins in them to see which could float with the most weight. We also made some out of clay. They were fun to make. We also learned about matter, volume, and density, and we did experiments to see how water was displaced and how things could float. We were able to make a date float just by adding some salt to the water. Lots of salt. We also made lava lamps with colored vinegar and oil and Alka Seltzer. The seltzer made a reaction, and the bubbles rose through the vinegar and oil since they were less dense.  It has been an awesome beginning of the school year.
