 This is plant post three. This post will be about pollination. Pollination is when a bee or any pollinating insect pollinates a flower. Then it will turn into a fruit or seed pod.

We have been pollinating the last several days. First, the petals came off and then the flowers  started getting seed pods.

CONTROLLED OBSERVATIONS-

Our tallest plant was 12cm and the others were 10cm,8cm 10 and a half cm.

The plants are all still green.

Our plants still have 4 leaves.

One plant has one flower.

MANIPULATED OBSERVATIONS-

Our tallest plant was 12cm and the others were 8cm and 10cm

The plants have some red and green.

Our plants still have four leaves.

Our plant has  one flower.

I predict this week that our plants will get some seed pods.

This is blog post 2. I am going to update you with the measurements of the plants over the last 2 to 3 weeks. These are the very important updates.

 

On June 1st the highest the controlled plant had grown was 8 cm in cell 2. By June 5th the highest the controlled plant was 14 cm in cell 3. The plants now have buds and some of the buds have bloomed into yellow flowers.

 

On June 1st the highest manipulated plant was 12 cm. It has grown really tall. We have been watering the manipulated plants with red food coloring. One of the cells has a little speck of red on the plant stem. The manipulated plants have two flowers, the same as the controlled plants.

 

We have noticed that the manipulated plants are a little bit shorter than the controlled plants. They have the same number of flowers, and the flowers are both yellow. I think the manipulated plants are a little shorter because they are adjusting to the food coloring.

 In class we are studying a plant unit in science.  When we started to plant we put wicks into each cell.  We have wicks so when we have no school they can suck up water from the felt and give it to the plants. Then we put some dirt in the cells half way up.  Then we put in 3 fertilizer pellets then we added more soil. We used an index finger to make a hole in the dirt. We put 2 seeds in each cell. We then covered up each cell with more soil to the top.  

 

We have two quads, one is controlled and one is manipulated. The controlled is everything stays the same, we don’t change anything.  We are giving the controlled 5 drops of water, same amount of sunlight using the plant light, same soil, fertilizer, and 2 seeds. On day 3 the plant started growing and it was 1 cm.  On day 3 there was 4 leaves and it was green. On day 7 in cell 1 it is 3cm . The highest plant is 4cm in cell 2 and has 4 leaves.

 

On day 6 we added 1 variable which was red food coloring. We are following the scientific method. Our scientific question is what is the effect of altered water on plant growth?  Our hypothesis is if I add food coloring then I think it will still grow because the water is just a different color. I also wonder if the plant turns red.

Technology  solves problems  and it makes life easier for people.  My object is a scissor and it is technology because it helps people cut. If you are doing a project and if you have to cut something out, you can put it on your project.  Before they invented scissors they had rip paper instead cutting it.  If you rip paper it isn’t as neat as cutting paper.  My scissors are made out of metal and plastic.  It is light, hard, smooth, rigid, colored, and is both pointed and flat.

maglev train day 1

A maglev train has no wheels.  It floats over the track track and goes really fast.  It works by electromagnets and that’s how it moves. My groups plan was to have 12 circle magnets on the track. For the train we used five circular magnets. This did not work so we had to change this plan.

 

Today we used two strip magnets for the train and for the track.  This worked because the magnets were even. Then we used twelve circular magnets for the track and one strip magnet in the middle of the track.  For the train, we used five circular magnets. These ideas didn’t work because they were not lined up correctly.

 

My experience with my group was good because we all listened to each other, shared ideas and did not fight.  We talked to each other to figure out how to make the train float and that worked well. It was challenging to get the train to float.
