Science Experiment #2

vkarp26 on

Today we were doing a science experiment, we were mixing many different liquids ( water, oil, and vinegar) with colored sugar (my groups color was purple). The first experiment my group did was Water and Colored Sugar. The solvent in this experiment was the water. The result of this experiment was that the sugar sank to the bottom, and the water got colored and the colored sugar lost its color. The next experiment was Oil and Colored sugar. The solute for this experiment was the sugar. Our hypothesis was confirmed, our hypothesis was: If we mixed the colored sugar and oil then it will be similar to the water but a lighter shade of purple. Our final experiment was Vinegar and Colored Sugar. Our hypothesis was: If we mix the vinegar and colored sugar then the sugar will not dissolve and will stay the same and the vinegar will stay the same color. Although, our hypothesis was denied. It dissolved within 5 seconds which was very surprising also, the color was much darker then the other colored sugar experiments. I learnt so much from this like how liquids that are all similar looking and feeling have very different reactions to the same thing!

Save the World with The Power of Recycling

Today, Ms.Boyer’s friend, Monica came into our class to teach us how to reuse tinfoil and more!

After lunch, Monica came into our class to teach us how/what you can do by reusing tinfoil we also  were answering questions that were about breaking apart and building it back together. Each student got one packet that Monica made which had questions inside of the packet. Each student went to their seat and filled out the first question,”Write or draw things in the room that can be disassembled easily?”, after a look around the room, the first thing that came to mind was a yoga ball when it deflate’s and you have to pump it back up. There were more questions but all were similar. So, when we started to build, we made a piece of clothing out of a piece of tinfoil, I decided to make a shoe, how i did that was by molding my foot and making it into the design I liked. The next task was, that we had to make something with the same piece of tinfoil, for someone at your table. Since it is valentine’s day I made my friend, Julia a heart. Our third task was trying to collaborate with our table, we had to find a way to pick up bottle caps with no hands, the tool I created was, getting two pencils, a rubber band and tying the two together. The fourth question was, collaborating with two tables do the same task, I did the same thing. Sadly, the activity had to end. My favorite part about today was making my shoe because I loved to walk around in it.

See you next time, yours truly,

Week 3 Lima Beans

WEEK 3 ON LIMA BEANS

Introduction

This is our third week on lima beans. We have three lima beans growing one controlled and two manipulated.They are all in a zip-loc bag and with three growing in each bag.

 

Controlled

Our controlled plant is okay. Two out of the three lima beans is growing upside down and so it will not grow because the roots will have no water. Our other one is growing like a regular plant so it is very healthy.

Manipulated(no sunlight)

Our no sunlight is not growing because plants need sun to be healthy because sun gives it water then inside it makes sugar and that is the plant’s food. Plants need the same things as we do:food, water, and air.

Manipulated(no air)

And finally we have no air but actually it is not bad it looks like a good and healthy plant. It is long  but it will get trapped because the bag is closed so it will not be able to open the bag with a really light plant.

Conclusion

Week three on lima beans is going great hope we have more next week!

 

Week Three on Plants

Week Three on Plants

This week is our third week on plant unit. Our kinetic sand got  thrown out because it wasn’t going to workout. Plus, our no sunlight died. So now we have a controlled plant left. After our pollinating our plant changed. All of the flowers fell down, but that was normal and part of the cycle. Then we saw seed pods. The seed pods were long and wide. Our biggest plant has about 10-12 seeds in it. Our largest seed pod has about 1-16 seed in it.

Our third week was much different than all of the other weeks because of the petals  that have fallen down and because of the seed pods.

Seed Pods

Seed Pods

This week I saw in my controlled plant that there were seed pods. When all of the flowers fell I got confused. I told myself, ”Where did all of the flowers go?” After we had a science lesson I understood it more. It was because of the pollinating, it was part of the cycle. Last week our seed pods were a bit wide and a little long, but now it is completely different. Now it’s much wider and much longer. Seed pods hold seeds, there is not just one seed there are more. My group predicted that there was about 10-12 seeds in there before. Now there is about 14-18 seeds in there. My groups pollinating and our seed pod units was successful. That is how our plant unit went.

Week 2 on plants

Week 2

This us our classes second week on plants. Our controlled plant has grown a lot! Before it was 2in. Now it is 3 and 5in. Our plant looks very healthy we are watering it and giving it sunlight. It is green and tall. Sometimes we measure it and some other times we write down our observations.

On our kinetic sand group nothing is growing. I think it is not growing the same reason as it did before. I will say why it is not growing now, the kinetic sand won’t split apart and the water will not absorb to the kinetic sand.

Also, my whole class (including my teacher) are making a plant that has NO sunlight. We are taking turns watering the plant. After we water we make observations in a packet (also for the manipulated plant and the controlled plant). Our no sunlight plant is not looking very healthy. I think this because it is not green it is yellow and because the stem is white not green.

I thought over all for the second week  the controlled plants grew compared to the first week. This is what I think about the second week of plants

My First Week On Plants

Week One of Plants

On May Third my class has started a plant unit. My group has chosen to plant in kinetic sand. So first what we did is we planted it in a cell, then we put in wicks.  Also our whole class has a plant growing with no sunlight. My group is also planting a regular plant. Our group’s rotation is that two people water each day. One will water the controlled one and one will water the kinetic sand one. Our kinetic sand one is not growing but our controlled one is growing.  We were going to do it in regular sand but since we had none we choose not to plant it in regular sand , instead we chose to plant it in kinetic sand. My group doesn’t think that it will grow in the kinetic sand because it will not split apart and the water won’t evaporate to the plant. That is what I did on my first week of plants.
