5th class in Room 7 have been working hard in preparation for the Globe project. We are investigating air pollution around our school. We are waiting for the results of our investigation from the research laboratory. To help us with our investigation we decided to construct a wind vane and a wind anemometer. We worked together in groups to plan and construct our chosen project. We’re looking forward to using our constructions as part of the Globe project.
We explored gravity and air resistance by designing and making our own parachutes and paper helicopters.
First, we watched Felix Baumgartner’s skydive from Space and discussed what forces we could see in action.
We then designed our own parachutes and landing crafts for an egg. We wanted to see if we could land them safely without cracking the egg. We used a range of materials to create our parachutes. Three out of six of our parachutes were successful!
Here are some of our designs and parachutes:
We also created paper helicopters. We dropped them from the same height repeatedly. We found the average time it took for them to fall. Then, each group adapted their helicopter to see if they could increase the time spent in the air.
Here is what our paper helicopters originally looked like:
In Ms. Ryan’s 1st Class we investigated different materials to see which ones were waterproof. We used Buster the puppet to help us. We predicted if the following materials were waterproof; rubber, cotton, nylon, plastic and tin-foil. We recorded our predictions.
We tested the materials by wrapping a piece of each one around Buster’s arm. Buster’s arm was dipped into the water for thirty seconds each time. We then checked to see if his arm was wet or dry. If his arm was dry it showed us that the material was waterproof. Sadly, poor Buster got wet when we tested the cotton, nylon and tin-foil as these are not waterproof. We would not recommend using these materials when making a raincoat.
We have been very busy in 1st class looking after our vegetable patch. The vegetables do not need water every day but they do need to be checked. We were very excited today because our seeds have really started to grow. Take a look at our pictures!
Today we began our Incredible Edibles Project! It is a healthy eating initiative for Primary School pupils. It encourages schools across the country to get busy growing carrots, lettuce, potatoes, strawberries and turnips.
We planted potatoes, lettuce seeds, carrot seeds, strawberry seeds and turnip seeds in our vegetable bed today. We had to make drills to place the seeds into and then cover the seeds over with compost. After this we watered our newly planted seeds. We will be busy bees over the next few weeks watering and taking care of our crops!
We are learning about light in first class. Light comes from a light source like the sun, fire, torches and candles. If you block the light source you create a shadow. Light shines through some things. Those things are transparent. Light does not go through other things. Those things are opaque.
Today during our experiment we created shadows using torches and objects to block the light. We also saw how light reflects off a mirror.
First Class looked at chemical energy and how it’s produced. We discussed what a chemical reaction is. We thought about a chemical reaction we created at the beginning of the school year when we mixed water, yeast and sugar and added it to our bread mixture. We then investigated two different types of tablets and looked to see what reaction they had in water. The first tablet was an allergy tablet and it did not dissolve in water. The second tablet was a Rubex vitamin C tablet. When the Rubex tablet mixed with the water it began dissolving rapidly creating CO2 bubbles.
After that we investigated if water an oil mix. We discovered that they do not mix because water is heavier than oil. We also investigated if our tablets would dissolve in oil. They didn’t. We added food colouring to the water and oil and found that the food colouring mixed with the water but not with the oil. We decided that the food colouring must be the same weight as the water but heavier than the oil.
We used this information to create our own Lava Lamps. We poured water, oil and a little food colouring into jars. We then added the Rubex tablet. Check out our Lava Lamp below.
