Spider Prey

Spiders eat insects like Flies, grasshoppers, crickets, wasps, mosquitoes, moths, butterflies, and beetles)



Spiders live just about everywhere. The only place spiders don't live is in Antarctica.

Spiders are a part of nature and also very scientific. Because they are all around they a great species to observe.



Whenever I saw the spider. I saw it trying to get a moth. The moth was trying to flap it's week and the spider would move away very quickly whenever the moth flapped it's wings.




My mom's camera is perfect for observing science and nature and other cool facts about science. Because it has a big lens it can zoom super close.

Spiders catch their prey inside a web of course. Forgotten webs are called cobwebs. I think that sometimes bugs get caught in cobwebs and leaves a tasty treat for other spiders that come around. 

when an insect gets caught in the web some people might think it gets poisoned when it touches the web, but really it doesn't. The spider waits somewhere secret for an insect to fly into it and then it sense vibration once a bug is trapped. 

It chases after the insect after it is caught in the web and it bites it's fangs into the insect and inject venom. The venom poisons and paralyses the bug. Our spider would crawl down to the moth and then run away and it did this six times to be exact until the spider finally got to the moths head and stuck the fangs in. 

Spiders can't chew their prey instead they just drink the blood and juices from inside. 

The next morning we observed that the moth was left all dried up. 

A few hours later the moth was gone, but the spider was in a dark corner of the picnic table which was his hiding spot I think. 

I hope your favorite animal becomes a spider because they are one of the most helpful animal on the planet because they kill mosquitos. I think it's a good thing we have a pet spider in our backyard. 

bye bye. 

OIL AND WATER AND SOAP.

This is an experiment about mixing water, oil, and soap and observing how the agents interact. 

For this experiment you will need a clear container with a lid, 1/4 cup of oil, a 1/2 cup water, and 1/4 cup of dish soap. 

First step fill the container about half way with water. 

Next add oil to the water.

Look very closely at the bottle. You will see something yellow at the top and water at the bottom. Put the lid on your container and shake it up. Let it sit for a few moments and the oil and water will separate.

The reason they do not mix to make a solution is because the molecules repel each other. Water likes water, and oil likes oil. Oil is lighter than water so it floats on top. 

If you add soap and shake it up you see that it will mix together! This is called emulsion. The dish soap likes water and oil, so it helps mix it up and bring all the molecules together. That's why we need dish soap because it helps dishes get clean. 

That's how you mix water, oil, and soap! 

The Ice Cream Experiment

Did you know ice cream could be scientific? 

 Ice cream companies hire food scientist to help them make it! I call this next experiment The Ice Cream Experiment because we are going to learn how the process of ice cream going from liquid to solid.

 

 

Here is what you will need:

whole milk

1 teaspoon of unflavored gelatin

3 tablespoon of honey

1/3 cup of evaporated milk

1 tablespoon of vanilla extract

 

 

Before you get started Turn your freezer to the lowest setting. For best results use a metal bowl and freeze it ahead of time.

Put 2 tablespoons of whole milk and 1 teaspoon of gelatin in a sauce pan. Let it sit for a minute.
Next warm the mixture on low heat and stir until the gelatin is dissolved.

*** For ice cream you want small crystals. That's how it stays smooth and creamy. Big crystals form when there is too much water and it's not blended well. That is why it is important to follow all the steps very carefully. ***

 

Remove the pan from the heat and sir in 3 tablespoons of honey and 1/3 cup of evaporated milk. 

***Invert sugars such as honey work better than granular sugar to keep ice crystals from forming.***

Pour the mixture into your cold metal mixing bowl and add 2/3 cup of whole milk and 1 tablespoon of vanilla. Stir well. Cover with plastic wrap and put it in the freezer.

An hour later check the mixture and make sure it is partly frozen. If not, put it back in the freezer and keep checking until it is partially frozen.

Mix the icecream with an electric mixer until it is fluffy.

***To have the right texture ice cream needs air mixed into it. Mixing also creates smaller fat molecules that hold bubbles of air in place.*** 

Cover it up again and freeze for at least two more hours. Once it is really frozen you may want to let it soften up a little bit so that you can scoop it out.

Now that you know how to make ice cream the fun part is putting toppings on it. For example you could put whip cream, sprinkles, or strawberries on it.

And then eat it!

Ta Da!

Cress Seed Experiment

Cress is a type of plant. Cress can grow on a paper towel as long as it gets water. After about three days the cress seeds will be at its full size. It needs SUN , WATER and that's about it.


These are the things you will need water, cress seeds, paper towels, and a small dish.

Rip up the paper in to 5 layers

and lay them on the dish.

Sprinkle some seeds on top of the paper towels.



Sprinkle the water onto the paper towels until it is completely soaked.

Place the dish next to your windowsill so that it can get sunlight.

Each day check on your seeds and water them. Everyday that you check on your seeds observe your seeds closely and you will see that something has changed.

This is what they will look like when they are finished growing.

As long as your seeds have water, air, and sunlight then they will grow. This process is called germination. These Cress seeds have turned into full grown sprouts and you can eat them, but I thought they taste like grass. 

That's how you plant a little tiny seed without soil. I hope you enjoyed this experiment. Bye.
