Play dough Circuit lab

In this lab we had 4 batteries some wires a switch and 3 light bulbs.

We had to use the materials and make a bell ring and make the lights light up. In our experiment the batteries were all connected together and the negative were touching the positive side of the batteries. there was a wire connected to the batteries  and the switch . The wire was connected to the metal bottom of both sides of the switch. The wire connected to the right side of the switch was connected to the middle of the circuit board so the middle light bulb had power coming to it. The other wire was connected to the outside of the circuit board so the 2 outside lights had power. That wire was connected to the other side of the 4 batteries. There was enough power to light up all 3 light bulbs. but when the switch was up there was no complete circuit so the light bulbs would not light up. When the switch was down there was a connection between both sides of the switch so the light bulb has power.

Periodic Table of Elements App

Problem: How to find an element on the periodic table and it’s properties.

Brainstorm: Find a picture of the periodic table in a book or look on-line.

App: K12  Periodic Table of the Elements


Review: The app is free.  I like the app because it has lots of colours and is easy to use.  The colours show which group the element is in.  When you click on the element it gives you lots of information about the element.  It gives you the atomic mass, the number of the element, the symbol, and the melting and boiling point.  It would be a  good app to use to study because you could say the information and then click on it to see if you are right.  The cons are that you cannot combine 2 elements to get a formula or its combined name.


Debrief: I searched the app store looking for an app on the periodic table.  I tried a few different apps.  I picked this one because it was the easiest to use and the information was easy to access.

I learned that there are a lot of  different apps and that it is not easy to find exactly what you are looking for.  I also learned that random apps appear in the category.  I searched chemistry and an app called FirstMet dating Meet Singles came up.  I learned that using an app was a good way to solve my problem.  It was way better than using a book because it is interactive.

Science Elements 4D

In this lab we used an app called elements 4d to try to get reactions from different elements.

An element that reacted with many other elements is oxygen. (O) It reacted with hydrogen. (H)

An element that did not react with any other elements is bismuth.  (BI) It did not react with sodium. (NA)

I think that some elements reacted together because some elements are missing a proton and a element that had an extra proton could of gave that element to a different element.

The table is organised by how many protons the elements have. I think that where the elements are placed that they will react with in the columns and rows. example sodium is in the red column and bismuth is in green column. So they  don’t react but hydrogen and oxygen are both in the dark blue column so they react.
