Ah the joys of middle school. The whole time Nishe’ has been in middle school I haven’t heard anything about the science fair. That is until this year. Now it is mandatory for the children to do a process. Now that I have two kids in middle school I have double the work. I totally don’t mind. It is just a little difficult. Well since we have plenty of time and Tyler’s teacher is wanting more updates I started with his project first. First thing we did was to search the internet for projects. We found his project at the website Sciencebuddies.org. Having two children that had a project to do and not wanting to break the bank we set a budget of no more than $30 for each project. I am working on letting go of the reins. So when we were searching for his project on the site I told him what our budget goal was and I let him search through the site. He chose the project “How Salty Does The Sea Have To Be To Make An Egg Float?”. The great thing about this site was it gave estimated amounts on how much each project cost. I think he made a great decision and we had so much fun doing this project. I took pictures and we made two videos. We made two because the first one refused to load.
My little man is a very interesting person he has to have everything set up. I decided to take pictures of the entire process and then we recorded him doing the project. Took me all week to get the video up because it refused to upload on youtube. In the end we wound up redoing the video which he and his sister got a kick out of. Totally love these two. Tyler enjoyed doing this project. I am so glad he enjoyed it and had fun with it. Here are the pictures:
Here are the materials we needed: 5 eggs, 5 cups, table salt, and water
We started off with 5 cups and 5 eggs which we labeled with a permanent marker. Then we filled the cups up with 250 milliliters of water or 1 cup. Then we got started. In cup number 1 we added no salt so we can see what would happen without any salt. It sunk straight to the bottom. Cup number 2 first we had one tablespoon of salt and put egg number 2 in. It sunk. Then we added another table spoon and added the egg again and once again it sunk. Oh before I forget with each tablespoon added you have to stir the salt until it completely dissolves.
Then we moved on to cups 3-5. In cup 3 we ad 3 tablespoons of salt and again it sunk. Cup 4 we added 4 tablespoons of salt and that’s when the egg started floating. I should have gotten a pick of Tyler’s face he was fascinated by it. For the heck of it we did cup 5 even though it wasn’t necessary and added 5 table spoons of salt again the egg floated. Then Tyler poured in some tap water to see what would happen and the egg floated down midway. After we were done we put the eggs back in the carton. No eggs were harmed in this process but they were harmed when they became breakfast this week. Ha ha ha!!!
The entire project cost us no more than $20. So we were $10 under our budget. Woohoo!
Here is the video (sorry about the length) :
Ha, very cool. Loved the science fare growing up and always went to the City Finals! I remember once I swabbed public payphones and home phones to see what germs I could find. My grandmother has a lab at Howard well the Microbiology and constantly let me swab things. My findings were gross haha. I can’t wait to have kids because I’m making sure they do their projects! hahaha .
Yes I had fun doing the project with him.
