Yesterday in Science we were timing how fast are reactions were to catching the ruler as it fell. From the results we got you can see that when it starts out touching are hands we have a faster reaction then when it starts in the air. I think I got good reactions to catching them because I got some small numbers. I think that when I was catching them I would get better then go back to what I got at the start but it was still fun to see what I got. Here are my result.
For science today we were learning about Microscopes and cells. We had to pair up with someone and then go get a slide and then go to a microscope. When I was doing I couldn't see much but I was still try we didn't get really that much but it was still fun.
For science this term we have been learning about taste and smell. We had to go in groups and try different types of food. The first week we did Taste and the second we did smell. Are aim was to see if we could guess the food buy the taste of it.
For the smell one we had to block are nose to see if we could guess what fruit it was without smelling it. We had to get our fruit then have one person in the group close there eyes and block there nose and then the other person would pick a fruit and put it in there had then the person trying the fruit would guess what it was and then do it all over again with a different peace of food.
For the taste one all you had to do was close your eyes well the other person puts it in you hand once you put the food in your mouth you were allowed to open your eyes and try and guess my Group did okay with this but we did get a few wrong the easiest one two guess was the orange flavor. Once we had finished doing all the other activities with a group we had to do one by our self we had to try and guess which side of the tongue is Sweet, Sour, Salty and bitter. It was really hard to figure out what part of your tongue was which but i did it in the end.
We had to put baking powder,Salt,Sugar and citric acid. All the taste and smell experiments have been all really fun.
For Science we were doing Pocket Rocket. To do the pocket rocket you have to have a little container,Baking soda and vinegar. When the Baking soda and the vinegar and when they mixed they made a chemical that made it pop the lid of. To start you need to get the right measurements of vinegar(8ml) and baking soda(1/2 a teaspoon) then you put either one in first and then the other one then you had to quickly close the lid and walk away and see if it worked if it doesn't then you can still do it again without cleaning the container. Gemeve and I were in a group together and our one didn't work very well every time we tried it didn't work but we still had fun.
Indicators
For science we we have been learning about indicator acids and alkali. It was fun seeing all the different thing that happens to the Tea,Turmeric,Cranberry juice and water it was cool what colours they turned
For science we have been learning about Acid and alkali so we put them in test tubs with other liquids
What is Acid:
Its something that can be use in experiments and some types of food and cooking things
What is alkali:
Alkali can be used in science experiments and is in some cleaning product and turns blue when mixed with something
What is an indicator:
It changes things to a different colour when mixed with thing like it turns acid to red and alkali to blue
Describe the 4 indicators we used:
Cranberry juice- red, purple, Drinkable
Tea-hot water to fully use, Drinkable
Turmeric-yellow orange- dissolves in water, but in cooking
Universal indicator- water Drinkable, cook able and eatable
Gummy Babies Osmosis
Keah’s Hypothesis:
I think they will loose there colour and they will grow bigger
I think the salt solution and the water solution is going going to grow less than the others and and that the sugar solution will grow more than the others
Gemeve’s Hypothesis:
What happened:
The water one grew the most and the salt one that grew less they had lost there colour and the water ones split in half
We think the water one split in half because it had absorbed all te water and got to a certain point were it just split.
Water:biggest lost most colour split in half
Sugar:Medium lost a bit of colour
Salt:smallest didn’t do mush and only really lost colour
Yesterday for science we were doing an experiment with skittles. What you had to do was you filed up a container with hot water and then get 4 or 5 skittles and put them in and watch the colour fade into the water. I was with Ayla and Gemeve we got some really nice photos of the water when the colour came of the skittles into it. Once the colour was in the water we were allowed to mix it around at first when you mixed it a little bit it looked nice kinda like tie dye but then when you mixed it more it became brown.
What things did you notice? Can you make five observations?
The colours faded from the skittles.
the skittles made lines in the water from where the skittle colour faded.
It coloured the water.
the water made the skittles drain the water
The coloured water mixed together and made an ugly colour
Did anything surprise you? What weren’t you expecting to observe?
No-Keah
I wasn’t expecting the colours to stay in their own bubble I thought they would automatically merge with their neighbors boarders and make a mixed colour line where they joined. - Ayla
Not really- Genevemema
what colour is more dominant
Why was the lines forming in the water from the skittles- Gemeve
Do you have any ideas about why certain things happened?
no-Keah
No-Gememema
yes-Ayla
What could you do to see if your ideas are correct?
For Science we have been learning about the Bunsen burner. Yesterday we had to investigate which flame on the Bunsen burner is hotter(Safety Flame,Roaring Flame) We had to put water in Becker up to 100 and measure how cold the water was before putting it on the flame and then see how hot it got after 4-5 mins. Mine and my partners safety flame water started at 11 and ended at 50 and our roaring flame stared at 11 and ended at 54. So from what Me and my partner got the roaring flame is hotter.
Evaluate the practicals
It needs to be a fair test because some people might have different things and are struggling
To keep it a fair test we need to have the same things so no one has something better
kinda some people had all there things and some people didn't like me and my partner
make sure everyone has the things they need to do it
Today for science we are Learning how to use the Bunsen Burner and writing down Lab safety rules.we are going in groups up to the burners and lighting and testing them we learnt a bit about them yesterday but today we get to light them.It was really fun to light and we got to move around the collar.to be safe we had to wear goggles and light the flame far away from us.
Lab Safety:
Goggles on
Hair up
No Eating
No sitting down during a practical
don't leave your experiment alone
if you spill something or something breaks tell the teacher
wear covered shoes
Bags under table or
No running around
Listen to what the teacher says
Don't do any experiments without the teacher
