Chemistry Yield Lab Yields Excellent Results

Chemistry Yield Lab Yields Excellent Results

Chemistry students developed their methods and procedures for the Factors Affecting Chemical Yield assignment and took to the lab to run their trials. There was a choice of investigating either sodium hydrogen carbonate (baking soda) or potassium carbonate and...
Dehydrating the Hydrate

Dehydrating the Hydrate

Chemistry students completed a quick lab activity in order to apply their stoichiometry skills to determine the amount of waters attached to the copper sulphate crystals from the chemical cabinet. They performed the heating (using the espresso stove and stand!) and...
Decomposition of Water

Decomposition of Water

Chemistry students had a chance to perform an interesting and hands-on reaction using the help of a 9 Volt battery. This was the same activity done with the 7+8 Science class last year and it worked well again. Water was electrolysed into hydrogen and oxygen gas using...
Seeing is Balancing

Seeing is Balancing

Chemistry students were given a visual challenge to balance a combustion reaction using the molecular model kits. They had to build the correct amount of each reactant and product in order to balance. This visual and hands on activity seemed to help reinforce the...
Solving Mysteries with Chromatography

Solving Mysteries with Chromatography

Chemistry students were given a forensics challenge to solve by determining the correct black marker used by a teacher to write a mysterious note seen below. Are black markers really black? How is black ink made? We used knowledge of mixtures whir using the new...
The Separation is in the Details

The Separation is in the Details

Chemistry students were given a challenge to determine the proper sequence of events to properly separate a mixture of substances using various methods. To do this, they were given a stack of cards with different actions or terms written on them. They then had to...
Classification Venn

Classification Venn

Chemistry students tried a new way to understand the classification of matter this year. They planned and created a Venn diagram that shows where each type of matter belongs. They then decorated and drew pictures to finish off the...
Covalent Networking

Covalent Networking

Chemistry students used the healthy stash of molecular model kits to build some covalent network solids of diamond, graphite and silicon dioxide. The SiO2 was amazingly difficult to build properly Рso many different connections to keep track of. Building sheets...
Being a Good Sports Drink

Being a Good Sports Drink

The Chemistry class investigated the content of two different sports drinks. They were challenged to determine how much salt was present in each brand by creating a standard curve by measuring samples of known concentrations. Then, they would measure each sports drink...
Try on Some Ions

Try on Some Ions

Chemistry students used some freshly made ion puzzle shapes to help reinforce the concept of balancing charge when creating ionic compounds. The number of teeth on the puzzle piece correspond to the charge (positive or negative) of the ion. A proper compound will...
Periodic Table 2.0: The Rebuild

Periodic Table 2.0: The Rebuild

Two years ago, the grade 7+8 class worked hard to construct a giant periodic table that covered a large section of the classroom wall. Over time, the colours faded and I had new ideas for an improved version. This year the Chemistry class worked together to come up...
Concept Review with GOBY

Concept Review with GOBY

In order to prepare for an assessment in bonding, the Chemistry students tried a out a new game I put together (very last minute) to review various types of concepts/questions. GOBY stands for Green, Orange, Blue and Yellow, although there was not enough time to make...
