Laina- Creating Simple circuits

Today I learnt something interesting.  We had to do a simple circuit. First, I drew a diagram. Then we made the circuit by following my diagram. The circuit will only work with 2 batteries, not one. I also learnt that if the battery carries more power then the bulb will be brighter. If it carries less power then it will be darker. This simple circuit was great and amazing to do.  

Proving A fire is a chemical change

Chemical change: Fire

Ask a question - When will I notice a chemical change?

Construct a hypothesis( make a guess) - When the match/paper is lit.

Conduct the experiment - //Making a fire//

Record your observations and data colour change - Colour change Temperature change Release of gas It became irreversible A new substance was formed

Analyse information - Once the newspaper was on fire it turned into a new substance, ash. The temperature change caused the newspaper to break, turn black, smell and smoke up. The smoke is also a release of gas. As for colour change it turned black.

Alicia- Chemical Changes through cooking

Walht: Write a paragraph on chemical change.

Baking Pikelets to see Chemical Changes. First of all a Chemical change is a result of a new substance in which can not be reversed. Before we discover chemical change, we needed to complete the scientific method. Asking a question and making an assumption. Combined ingredients help chemical changes but through baking, it is heat. It is simply like applying milk to the dry ingredients ( Flour, Sugar, Baking Soda e.t.c.) It becomes liquid. While cooking the pancakes you will observe the chemical changes when…

• Release of gas (Bubbles form)
• Colour change  ( Golden brown)
• Temperature change

Once you know when your pancakes are finished through chemical change, you can enjoy them. Delicious!
