The Exploding Lunch Bag with Guest Bloggers Ella and Morgan

Materials:

1/4 cup warm water, 1/2 cup vinegar, 3 tablespoons of baking (bicarbonate) soda, tissue, zip lock bag

 

Ella:

  1. You put the three tablespoons of baking soda in a tissue and fold it up neatly.

  2. You get some warm water and vinegar in a zip lock bag.

  3. Put the tissue with the baking soda in the zip lock bag and zip it up.

  4. Shake the bag up a little bit.

  5. Put it on the ground.

  6. Step back and wait for it to POP!

 

Morgan:

When you mix a bunch of vinegar and hot/warm water with 3 tablespoons of baking soda wrapped in a tissue, and put it all in a zip lock bag, it will eventually pop.

Whizz! Bang! Pop!

We have had so much fun completing our Science Experiments during our Whizz! Bang! Pop! Inquiry.

Here are some photos from our Magnet Maze experiment where we discovered that Magnets have two poles, we call one the north pole and one the south. Depending on which poles you place together they can either attract each other or repel. Opposite poles attract.

Our Static Electricity experiment was so noisy… watching everyone’s hair go in the air was absolutely hilarious. We also made an aluminium can roll across the table without touching it. Here’s how it happens…

Rubbing the balloons against woollen fabric or your hair creates static electricity. This involves negatively charged particles (electrons) jumping  to positively charged objects. When you rub the balloons against your hair or the fabric they become negatively charged, they have taken some of the electrons from the hair/fabric and left them positively charged.

They say opposites attract and that is certainly the case in these experiments, your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it. This is similar to the aluminium can which is drawn to the negatively charged balloon as the area near it  becomes positively charged, once again opposites attract.

We follow up most of our experiments by writing a science report which lists the materials used, the procedure to follow and what happens during the experiment.

Here are some links to some great Science websites that we have used in class.

St Johns Visit

Julie from St Johns visited us during week 2 this term and taught us about safety and first aid. We learnt about looking for dangers in an emergency situation and what to do when people are injured.

Some people were bandaged up and it was hilarious. Although we realise it wouldn’t be funny if they were really injured.

We also discovered what we needed to do if there was a real emergency.

We should  call 000 and state which emergency service we need. We need to know our address and our telephone number.

Do you know what to do in an emergency? 

Do you have your emergency information card near your telephone or on the fridge?
