Science Week 3

This was a couple of weeks ago now, but I’ve been hectic since and this is the first chance ive had to upload photos and write! Science week was at the end of August. As I knew this was the last one i would be doing with the students I wanted to make it special and put lots of effort into thinking of things the student could make, rather than watch me at the front demonstrating something to them and thats how I decided on these experiments.

 

My year 4s learnt how to make Hoop Gliders. They fly better than a paper aeroplane and are really simple to make. I thought the students would be super quick making them so that we could spend the rest of the lesson outside throwing them and hitting targets. But no, there were 3 strips of card and the students took most of the lesson decorating the card. All you need is 3 strips of card (5 inches long, 1 inch wide) a straw, and tape. Curl one bit of card into a small circle and tape it. Make the other two into a big circle and tape it. Then tape the small hoop at the bottom of the straw, and the bigger at the top of the straw. Voila, you have a hoop glider. It takes about 5 minutes to make unless you want to decorate or unless the students struggle putting tape on (some of mine did!)

 

Here are the picture of my classes throwing the gliders at me!

My Pratom 5s had more of an activity week rather than strictly science but the activities i followed were in a science book! For the first lesson the students made a guitar from a shoe box, old pens and elastic bands. It was super easy and taught them about high or low pitch, depending what size pen was used. For the second lesson they made a basic harmonica. All you need is more straws, card and double sided tape. They put the tape on the card then lined up all the straws and then cut the bottom diagonally so that when you blow into the straw different pitched sounds can be heard. I had a fantastic eureka moment with one class who finished early. So i made them put all the harmonicas the same way round and had them copy my tune. At the end i made them put all the tunes together and we made a sort of melody. I think its possibly the first time teaching that every single student knew what to do and did it in time. It felt fantastic! Didn’t sound half bad either…

 

Was too busy making melodies to take photos so here is a drawing instead.

For the year 6s they were instructed to make mini water turbines in groups. This was not simple to make and needed a lot of stationary and parts! Including; big water bottle, 6 screw top lids from bottles, a heated glue gun, 2 discs of plastic, a knife, 30cm wire and strong waterproof tape. Also a bucket for the water to run into.

 

The students started by giving the disks of plastic and the lids to to the teachers who put hot glue on, then they were able to set them out they way they wanted to make a functioning wheel. A pin was then used to make a hole to thread the wire through. The wire was then bent to hold the wheel in place and taped to the bottle. A knife was used to make a hole in the bottle for water to pour through.

 

Some of the experiments worked and some didn’t. It was better if the hole was lower because then the water had more pressure on it and would come out faster and hit the wheel stronger and turn it. Most students had to keep the water flowing from the tap to get it to work correctly and a few broke the wheels. I also gave them the option of making the plastic disks smaller. These worked better as the less weight meant it was easier to turn with little water falling onto it.

 

Once again didn’t get a photo so here’s another drawing.
