Year 5 has had fun learning about mass. We had 4 stations of learning relating to mass that had different questions and problems for us to work out. Here is a summary of all the exciting things we did.
Station 1: Money, Money, Money:
The learning intention for this station, was to make sure everyone got a better understanding about mass and had the opportunity to measure using grams and kilograms.
We were told that we had been given a prize of money, but had to work as team and figure out which prize would give us the most money.
Our prize could be just one of the following:
- ¼ a kilogram of $2 coins
- A metre long of $2 coins
- 750g of 50c coins
We had to use the rulers and scales to work out what we should pick as our money prize.
Station 2 – Weighing Tonnes
Our learning intention was to learn about tonnes and kilograms.
We were asked to find out the mass and facts about a large animal of our choice and then compare their mass with ours.
We created a table and used it in our groups to record our learning. Some of the animals we chose to conduct research on included: a blue whale, a walrus, a zebra, a giraffe, and lots and lots more. We converted the animal’s mass to kilograms to compare our mass.
Station 3: Net and Gross Mass
At this station, the learning intention was that we should learn about net and gross mass, and that’s exactly what we did!
We got given 2 cans, 1 full of peach pieces and one of pineapple pieces. We looked at the labels on both of them to see how much it said its mass was.
We then weighed the cans with the juice in it on the digital scales. This, we learnt was the gross mass. The gross mass of the peaches was 492g, and the pineapples, 503g. But then came the fun part.
We had to carefully pour out the fruits into the plastic bowls and then we weighed it. Without the tin, the peach’s mass was 439g. (This was the net weight.) This meant that the tin was approximately 10% of the gross mass. Then the pineapple’s mass without the tin was 427g, which means the tin was approximately 15% of the gross mass.
Then came the best part of all…..
We got to eat the fruit salad!
Station 4. – Frank’s Arms:
This activity was great fun. First, as a class, we read a funny book about mass called ‘Counting On Frank’ One of the activities was when Frank had to carry lots of cans of dog food.
Our part of the task was to find out what mass of cans of food we could carry. We wondered how we could most successfully calculate the total of the mass of the cans. We decided that we could measure our mass and then measure our mass again whilst carrying a packet of cans. We could then deduct our mass from the larger mass to calculate the mass of the packet of cans.
We began by measuring our mass on Mrs F’s bathroom scale. Then we each took turns carrying as many cans of food as we could in plastic bags, walking up and down the verandah outside. After we made sure that we were carrying as much as we could, we weighed ourselves with the cans in the plastic bag. We then we deducted our mass and we had found our answer!
We definitely had loads of fun and we loved every bit of it (especially the eating)! We learned a lot and will certainly never forget this wonderful unit full of learning!
