Maginet car

 today in science my group and I were testing a magnet car. we found that the car could climb 2 books it could also jump climb and best of all it can go super fast. fun fact it goes faster down a ramp and it took in total it took 24 seconds for the magnet car to get across the basket ball court 

Brain box

 in science today my group and I were doing brain box. a type of science safe for kids with power electricity sound light and much more. for most of the time my group did not have the fuse to start the experiment there for our fan would not work. we tryed a lot of things but it would not work why? because we did not have the fuse. later on in the day we got the fuse for the batteries so we put the fan back together and put in the fuse and we and tested it. the fan was going so fast that the entire fan flew in the air.   

coin drop

 today in science we were doing an experiment called the coin drop we you will need coins small paper and a cup. you place the cup down then you put the card and put it on the cup and put the coins on the card. then what you will need to do is flick the card and the coins should fall in. we were trying to see if different coins had a better outcome we used 5 cent 50 cent 20 cent and 10 cents

M&M stacking

 in science today were M&M stacking and stone stacking we were trying to stack 5 M&Ms. we started with a practice by stacking stones it was way harder than it looked.  some people have luck on there side and they got 4 or 3 but the Maori all blacks tied with the guinness world record of an amazing 5 the highest I got was three

cold air balloon pt2

 

in science today we were learning about newtons there laws and chemical reactions the reaction we tried was what would happen if we put baking soda and vinegar. I observed the reaction of the chemicals when they meet together. but I don't know why it would have that sort of reaction. we found it challenging to find the right size nozzle of the bottle and also to find the right ballon size. it was easy to fit the baking soda into the balloon so that it will go in the bottle. What to do next time is bring a pump bottle so that the experiment will go

better.

cold air balloon

 in science today we were learning about cold air balloons were we put baking soda into a balloon and vinegar in a bottle so then there was a chemical reaction

I observed the experiment we watched showing us how to do the experiment.  

I found it hard to think of what chemical reacts that way to baking soda.

I found it easy to  insert the video into my blog to show other people how to do what we did

next time I will work harder and avoid the distractions around me.

ballon rockets

during science today we were learning about newtons three laws of physics we were learning about the third law we found that if we have a small balloon the faster the balloon went further.

What did you learn I learnt that the less air in the balloon the further it goes

I observed how the balloon went as far as it did and how it flew

What will you do next time I will put less air in the balloon so that the balloon will go further

 

bath bombs

in science we Were learning about bath bombs and the science behind 1 cup of baking soda 1/2 cup of citric acid 1/2 of epsom salt -1 tsp of water 1 tsp of olive oil/ coconut oil/ almond oil 2-3 drops of food coloring. I found it hard to mix the ingredients with the food coloring beaceuse I left it to long I found it easy to pour half of the ingredients in to the bowl I really enjoyed making bath bombs because I gave my mum the bath bomb on mothers day. Next time I will do other colors then blue and green because they are my favorite colors.

 When a bath bomb comes in contact with water, the baking soda and citric acid react to make carbon dioxide bubbles. This is an acid–base reaction, where baking soda (also called sodium bicarbonate) is a weak base and citric acid is a weak acid.
