LI: To create a screencastify showcasing the anti-gravity glass I created.
Today, I have completed my first task of week five for the Summer Learning Journey activity and have created a screencastify that shows the anti-gravity glass I created. First, I watched the introduction video Nanogirl has uploaded on her site and I came to know many new things. I started by learning the meaning of gravity. It is the force that attracts a body with mass towards the centre of the earth, in easy words it is the force that pulls you back to the ground. For example, when a person jumps the reason they come back on the ground is due to gravity. Today we would be stopping gravity by making the anti-gravity glass in this activity.
I started by collecting all the equipments that were required to run the activity which were glass and cardboard. Then I cut the cardboard in the right size according to the glass by measuring the size. While making this activity, I came to know that anti-gravity is when another force stops the gravitational force. Basically, in this case the air pressure is pushing the cardboard upwards and the gravity is pulling the water downwards. The important point is that both of them are equal thus the water stays inside the glass even though it is upside down. Once I was ready for my experiment I went outside my house and tried it.
I really enjoyed completing this activity because I came to know what gravitational force and air pressure is and also got to check it by conducting this activity. The part which I enjoyed the most was doing the experiment because when I showed it to my brother he thought I was actually doing magic and got very shocked. The tricky part in this activity was holding the glass because it was very slippery and heavy at the same time. I think the advice I would give to the creators who haven't done the experiment yet, is to test the experiment outside the house because there are many chances that you will create a mess inside. I am excited to complete other Summer Learning Journey tasks as well.

Nice job on the anti-gravity experiment! You nailed it, and did a great job on your blog post too. I like that you screencast what you had done, and that you included a blurb explaining this process too! I especially liked how you put arrows in to show the gravitational force and air pressure fighting against each other! Ka pai! You also spoke incredibly clearly!
When I was little, my dad showed me that trick! It was magical. He also showed me another cool anti gravity one regarding centripetal force. He put water in a bucket, and spun it in a vertical circle and it didn’t fall out! The pressure of the water went to the bottom of the bucket so nothing leaked. He didn’t get a drip on him! How cool!
Do you know any other cool experiments?
Happy blogging!
