Science Project

 L.I: To learn about the different taste buds.

This week for science we researched and learned about the four different taste buds which is: sweet, sour, bitter and salty. After that we finally started the experiment and we tasted each bottle of liquid. Then we recored the information. 

After my investigation, I found out that the tongue has many nerves that help detect and transmit taste signals to the brain. Also not everyone has the same taste buds.

I enjoyed this experiment but I didn't enjoy some of the liquids because it tasted disgusting.

Osmosis & Transpiration

 This week for tech we are leaning about Osmosis and Transpiration. Photosynthesis. Photosynthesis -make food Plants Water can only move around a flower by xylem.

In the experiment we used Food coloring so we could see the movement in the plant.

I enjoyed it because this experiment was really interesting and I liked how I could the blue in the celery.

Topic 5 - Flower power

L.I: To learn how to dissect a flower. For science today we learned how to dissect a flower. Before dissecting the flower you need to have your tools and it is:
  • Knife
  • Cutting board
  • Flower
We removed one petal and one sepal. Pinch the ovary and cut the style straight.
After that we prepared a pollen slide and saw it under a microscope. I enjoyed this activity because we got to learn how to dissect a flower.

I also learnt that a hibiscus has a a female and male gametophyte.

Science - Topic 4 Floating & Sinking

 L.I: To check which objects would float or sink. 

For science we did experiments on floating and sinking.  First we talked about floating, sinking and semi-float. After doing writing down all the information we know about floating and sinking we started the experiments. 

What is Negative and positive buoyancy?
Negative buoyancy causes the object to sink.
Positive buoyancy cause the object to float.

We checked the size, weight, composition, and made a prediction. For the first experiment nearly all the objects sunk and for the second experiment some of it floated and semi floated. 

I enjoyed this experiment because I enjoyed the part where we checked if it would float or sink.

Topic 3 (Trying out Laboratory Equipment)

For science out topic was about trying out laboratory equipment. we did. Also for science we did two experiments. 

We poured 200mls of cold water into the breaker and checked the temperature, then we scooped 10g of sugar into a petri dish. After doing this we poured the sugar into the breaker and timed it to see how long is dissolved. For the second experiment we did the same thing but instead we used hot water. 

The time for the first experiment was 1 minute and 3 seconds. The time for the second experiment was 15 seconds. The hot water dissolved it quicker because it's hot and it would the melt the sugar.

I enjoyed this activity because we got to do two experiments.

Topic 2 (Science)

 For Science we learned about different science equipment.

Some of the science equipment were a pipette, spatula, bunsen burner and other more.

We created a Google doc and have all the pictures of those equipments.

I enjoyed this activity because the experiment was fun.
