Egg Drop
May 1st
We did the Incredible Egg Drop. We ended up having beautiful weather. The students had to build a capsule to protect the egg from a 3 story drop. We used a window in the library. Mr. Morrison dropped the egg capsules from the window.
See pictures and videos below.
Speed of Hot Wheel Cars
April 17th
The students calculated the speed of Hot Wheel Cars and made a Speed Graph (Distance over Time Graph) of their data.
Air Trolley Lab
April 15th
Testable Question: How will the number of winds of the propeller affect the distance the air trolley moves?
Speed Equation
April 12th
We calculated the speed of classmates as they hopped across the classroom after learning the speed equation.
Sorry, no pictures taken.
Science Fair Projects - Challenge
April 11-12
The challenge students presented their Science Fair Projects both days. Here are some of the pictures below.
The following project were sent to the Science Fair at Queeny Park.
Motors & Study Guide
April 5th
Today we took apart a simple motor and put them back together. We found that these motors use electromagnets to function.
The second part of class we worked on our study guide for the Electricity and Magnetism test.
Sorry, there were no pictures taken.
Electromagnet Lab
April 4th
Testable Question: How does the number of coils wrapped around a nail affect the strength of the electromagnet (measured by the number of paper clips picked up)?
We found out that the more coils wrapped around a nail, the stronger the electromagnet becomes.
The students graphed their results and wrote a power conclusion about the lab.
Compasses & Electromagnet Stations
April 3rd
Today the students rotated to 3 different stations. At the stations the students made the following things...
1. Water Pan Compasses
2. Suspended Needle Compasses
3. Electromagnet
Sorry, I forgot to take pictures!
Magnetic Strength Lab
April 2nd
Today the students tested the magnetic strength of one magnet compared to multiple magnets.
Testable Question: How does the number of magnets affect the strength of the magnet(s) as measured by how many paper clips are picked up?
We found that the more magnets stacked, the more paper clips that will be picked up (the strength of the magnet(s) increase).
Magnetism
April 1st
Given a "Bag O' Stuff" the students first tested random materials to see which had magnetic properties.
Second, the students got a bar magnet and observed the magnetic field around a magnet using iron filings.

Wiring a House Projects
March 18-22
The task of the students was to wire a "house" with at least 4 rooms, a light bulb, and a switch in each room.
Click on the video below to see all the house projects and the voted winners for Most Creative, Neatest Wiring, Coolest Feature, and Overall Most Awesome-EST House!
Making a Filament
March 15th
We talked about a filament and how that is the wire that lights up an incandescent light bulb. We also discussed and analyzed advantages and disadvantages of using LEDs, Compact Florescents and Incandescent light bulbs.
Using nichrome wire, we made filaments and watched them glow.

You can see the wire in the middle glowing a reddish/orange hue.
See the orange glow in the middle of the picture.

Batteries
March 14th
In the beginning of class, we discussed the advantages and disadvantages of parallel and series circuits.
We talked about batteries and the necessary parts of a battery and how it works.
1. An electrolyte
2. a cathode (metal)
3. an anode (metal)
Next we attempted to make different kinds of batteries and read the amount of volts the batteries produces with a voltmeter.
1. Lemon batteries
2. Coke batteries
3. Vinegar batteries
4. Potato batteries

4. Potato batteries
We connected potato batteries to turn on a light bulb. Unfortunately we didn't get it to light up. According to the voltmeter we produced 2.5 volts, which should be enough to light up the light.
Series & Parallel Circuits
March 13th
The students made two different types of circuits - Series circuits and Parallel circuits!
The students unscrewed one light bulb in each type of circuit and observed what happened.

Parallel Circuit
Parallel Circuit with two batteries, with a switch
The parallel circuits allow the bulbs to be much brighter because each one is individually connected to the battery.
Conductors of Electricity / Using Switches
March 12th
The students were given a bag of stuff and had to classify the items as conductors or insulators of electricity. They made a simple circuit and placed the item in between to test it.

Switches
The picture above is an opened switch, so the light is turned off, because the circuit is broken.
Exploring with Electrical Circuits
March 11th
The students were given batteries, wires, and bulbs and were told to build circuits. They had the hour to explore and draw diagrams of the circuits they made.

Static Discharge
March 7th
Static discharge is the release of static electricity when two objects come into contact. Objects are left neutral after a discharge.
We watched videos of different electrostatic generators.
1. Wimshurst Machine
2. Van de Graaff generator - We watched a video of the largest Van de Graaff generator in the world.
Then each group experienced static discharge (a shock) with an electrophorus. Each time you pick up the handle (styrofoam cup) with the pie pan, it re-builds up a charge. Each time you touch the pie pan, you get shocked again.
