Sky High!

For Topic, we had to do a Fair Test experiment. First we had to plan out what experiment we wanted to do, then decide our variables (the things we will change/vary and measure/observe). Next, we did our hypothesis (what we think will happen). When planning was done, we did our Fair Test. After we've done the experiment, we went back to the google doc where we put all our information in (variables, hypothesis, etc.) and write down the results of the Fair Test.

Me and the people that I worked with for the fair test have all agreed to do the Coke + Mentos experiment, and decided to change: the type of liquid we use, and measure/observe the amount of liquid that's left in every fizzy drink. We used four types of liquid; Coke, Coke Zero, Lemonade, and Passionfruit. We predicted that the Coke Zero would spew the most out, but the Lemonade did, with the least amount of liquid left in the bottle.

I found it hard: Finishing the Science Board right in time

I found it fun: Doing the lettering for the title, and cutting different borders for the information that we wrote.

I found it easy: Doing the planning

Science Change

For this term for Science, we have been doing experiments and hypothesis. We
also have been writing and taking notes of what we do like for the Elephant
Toothpaste, the Vinegar+Baking Soda experiment. We had to write the
reactions of the experiments. We also have learnt what reactant/s, substance,
product, and Chemical Reaction means.

Substance: Is the materials you need to make a product.

Product: Is the thing that you made with the substance and reactants.

Reactant/s: Two reactants can make a product

Chemical Reactions: The reaction that the chemicals (substances) makes.

Example: Ice melting to water. If a physical change occurs, the physical
properties of a substance will change.

Science-Change

Today for Science, we did an experiment and we had to make a hypothesis (guess) what will happen if you put 1/3 part of vinegar in a bottle, and put 2 tablespoons of baking soda, then cover it up quickly with a cork. And this is my answer.

What do you think will happen? It will foam up and will fizz. Then the cork will fly away.

	What do you think these will be?
Reactants	Vinegar, Baking Soda, bottle
Product	Turns to gas (carbon dioxide)
Chemical Reaction	It’s going to form foam and will fizz, and the cork will fly away.

Was your hypothesis right/ wrong? Why? Yes because the cork popped when the foam reached it.

Science

In Science we are learning about change. Change happens when we mix or combine two different reactants (Substances together). When this happens a chemical reaction takes place.

Science - Change

I’m starting to learn about Science and change. This is what I
found out today. What new information can someone tell me?

Substance: Is the materials you need to make a product.

Product: Is the thing that you made with the substance.

Reactant/s: Two reactants can make a product

Chemical Reactions: The reaction that the chemicals
(substances) makes.

Example:

- Ice melting to water. If a physical change occurs, the physical
properties of a substance will change.

- Dry Ice mixed with water - Solid to gas

-To make oobleck - Mix cornstarch with water
