Science 9 House Project and Self Assessment

Project questions:

1: If you unscrew one light bulb then the other lights will go out if it is on a series circuit.

2: If you unscrew one light bulb then all the others will stay on if it is a parallel circuit.

3: the lightbulb in the series circuit would be brighter than the other ones because the two ones in the parallel circuit have to share the energy while the one in the series gets more.

4: you would have to add half the energy from the series light bulb on the two of the remaining light bulbs.

5: I think I collaborated a lot with my partner during this project. I think we built the house well but we could have improved on taping the wires a bit more.

COL:

1) I needed to research what a complex circuit was and I researched how to make a circuit.

2) I used the PHET simulations website to test my circuits to make sure the circuit designs worked.

3) we first came up with the idea, then researched that idea and came up with a conclusion after that.

4) we only used websites with .org, .ca or .edu

5) The project was very challenging to complete and things would randomly stop working because the tape wasn’t that good.

     I made a circuit that had a switch, 6 batteries, a bell, and 5 wires. I wanted to have more things in my circuit but it would need more power because the bell takes a lot of energy to run and there was no more batteries left. I think it was still a good circuit but I couldn’t have added more.

Science app review

tylerk2017

problem) Let’s say you need to find out what all the elements are used for because of a school project.

Brainstorm) You could google every single element and see what it’s used for, or you can download an app about the elements.

I found an app called Elements: The Periodic Table. explanation) this app gives you all the information you need about all the elements in the periodic table.It tells you the history of the element, boiling point, melting point, main applications, isotopes, where the symbol came from and that is only in the free version. The app also has a search feature where you can search for different elements. This app can help people learn by displaying information that won’t be on a periodic table. This app also only took me about 2 minutes to figure because of it’s simplistic design. I think I would rate this app 5/5 stars because I have no complaints about it and it gives me a lot of information about elements.

Q #1 What is an element that reacted with many other elements? Which elements did it react with?

I think chlorine is the element that reacted with the most other elements. I go it to react with hydrogen, gold, cobalt, and chromium.

Q #2 What is an element that did not react with any elements? Which elements did it not react with?

xenon didn’t react with anything we tried, it couldn’t react with chlorine, gold, silicon, and cesium.

Q #3 Why do you think some elements reacted with each other and others didn’t?

I think some elements reacted with others because of the molecules, some group up with others and some like to stay away from others.

Q #4 Do you think there may be a pattern to how the periodic table is arranged? Does it relate to how elements react with each other?

I think the periodic table is arranged in a way to make it easy to find elements that react with each other but I don’t think it’s built for that purpose.

 

plutonium and bromine can react with each other:
