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:
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.
We had great fun this week in Senior Infants in room 2. We wanted to find a good material to use in life jackets so we started by investigating different materials to see if they would float or sink when … Continue reading →
We had great fun creating lava lamps in 2nd class. Now we know that chemical energy is energy released during a chemical reaction. We found out that oil and water do not mix. Water is heavier than oil. For our … Continue reading →
We had lots of fun In Room 18 exploring how forces act on different objects. To begin, we guessed if each item would float or sink. Then, we placed the items into the water and recorded our results on a … Continue reading →
