Mad Scientists in Room 16!

We were lucky to have the team from Science Alive come and teach us about kitchen science. We had to use different ingredients found in a kitchen and test them to solve a mystery. It turns out that it was James who robbed Kate's shop! Here are Room 16's clever scientists at work trying to solve the mystery. Room 16 students have been doing science experiments this week and then writing about them during writing time. Check out some of the experiments below. We made our own CRYSTALS!

We got into pairs and chose a powder to dissolve in hot water. We had a choice between Epsom salts, washing soda and table salt. We discovered they all disappeared when we stirred them into the hot water. This showed us that they are all 'soluble'. After that some of us added in food colouring to our mixture and then placed two teaspoons onto a 'base'. The liquid in our mixture started to evaporate and our crystals started to form.







OOBLECK!

**1.** **Put cornflour into a bowl**

**2.** **Add half as much water**

**3.** **Stir together** **4.** **Play with it**!

How did it feel? What happened if you tried to pick it up? If you held onto a blob how did it change?









Balloon Blow Up!

1. Stretch open the neck of the balloon and spoon in 2 Tablespoons of baking soda.

2. Use a funnel to pour in 1/4 cup of vinegar into the bottle.

3. Carefully secure the mouth of the balloon over the top of the bottle.

4. Shake the baking soda into the bottle and swirl it around.

What happens? Why do you think this happens?
