Incredible Edibles Project – Room 4

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!

Light

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.

Lava Lamps

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.

Chemical Energy and Capacity

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

Heart Rate Before and After Exercise

Today in our class we monitored some children’s heart rates before exercise and then we monitored it after exercise. We found out that your heart rate increases after you complete exercise. These are the results Name Before exercise After exercise … Continue reading
