Homework: Plan a Science Experiment

As I said on Monday, I’d like us to start doing some simple science experiments as well as making the connection between science and your exhibition issues. This will help you understand how to think like a scientist and how to do experiments that are accurate and really help you find things out properly.

We can do these experiments in school, but you can also try them out at home too. Take a look at these websites for some ideas, then make a comment to tell us what experiments you’re interested in and what equipment you will need.

When you’re trying the experiments at home, why not get someone to take photos or video of you as evidence?

    I looked at the ‘Science Explorer’ website (the bottom one), and I saw an experiment called ‘Go with the flow’-under the mysterious mixtures catogory, and I thought it sounded interesting. I took a look at it, and it was about how water can create patterns by itself in a bottle if we turn it in different angles.
    I looked at the other website, and nothing seemed interesting. But this one was extraordinary. I looked at some other experiments I thought I would like, but they were so-so and I didn’t have the equipments.

    For the ‘go with the flow’ experiment, I had most of the equipment, and I can get the rest very easily. I can do this at school or home, but it may take a while to get everything set up. I need to get some food colouring (I might have some at home) and I need to check out some soap with glycol stearate in it, and I might have some at my house (I have to check the ingredients). I will need some tape, and a bottle (very easy) and a place where I can get water.
    Another experiment that I found interesting (also in science explorer) is ‘Flipsticks’ which is a toy where when you spin it it creates kind of like an animation. I like it because I want to know how it works, and how I can make it. the equipments are very easy to get because they’re simple stationary and I just need a printout of part of the experiment included in the website. It would be really cool to make up some by ourselves, and maybe do it like a filmstrip related to our exhibition issue. I’m doing this one probably tonight, because it’s easy to do and I will bring it to school. 🙂

    I had alot of interesting things and experiments- so I’m going to chare you my interests. This is from teh top website-
    – Color Changing Liquid
    – Fantastic Foamy Fountain
    – How to make Slime (Method 1)
    – Chemistry Cleans a Penny
    – Make plastic milk
    – Make bursts of colors in a tray of milk
    – A rubber chicken bone?

    And heres some from the second website-
    -Dramatic Static
    – Blowing Bouncing, Bursting Bubbles
    – Mysterious Mixtures ( Outrages Ooze)
    – It colorific! ( Black Magic)
    – Making changes (Crystal Creations)
    – Surprising Structures ( Geodesic Gumdrops)

    So theres my interests list, but I havent been through the instructions- so I’m not sure which ones I can do or not. I might be able to find some stuff around the house or at my moms office- since its where I spend (almost) all my afternoons on a weekday.

    May 10, 2011 at 5:57 pm

    Do we have to choose the ones from the websites or can we use our own experiments at home?

    • Mr. Sam
      May 10, 2011 at 10:48 pm

      You can use your own if you like, the websites are just to give you ideas.

    What I’m interested in is the Crystal Creations and the Flipsticks.

    Crystal Creation-
    I want to do about Crystal Creation because in Bangkok it is sunny and this experiment works best on sunny day.
    What I need for this experiment are:
    -Black construction paper
    -Scissors
    -A pie pan, cake pan, or shallow bowl
    -Warm water
    -Epsom salt (usually near the rubbing alcohol in the supermarket)

    Another things that I wanted to do is the Flipstics. It’s a kind of toy that we flip the sticks and you will see the picture moving up and down or etc. I want to do this because I want to know how it works and how you can make the picture move. I am always interested in making pictures move so I want to try.
    What we need for this experiment are:
    -print-outs of the “Flipstick Cartoons”, which you can click on in Step 1, or…
    white paper that you can use for tracing and black marker or dark pencil
    -scissors
    -bright colored markers
    -clear plastic tape
    -file cards
    -pencil, straw, or chopstick
    -ruler
    Also the flip sticks are easy to do so I might do some tonight and also bring some stuff to do it tomorrow too. 🙂

    I looked at science bob (the one at the top and I liked lots of experiments.
    The first one I saw interesting was the Incredible hoop Glider. In this experiment we need:
    •A regular plastic drinking straw
    •3 X 5 inch index card or stiff paper
    •Tape
    •Scissors

    I am planning to make the glider which consists of 1 big circle and 1 small circle.
    The connection is a straw. The goal is to make this glider go further than a paper airplane. To take a look at this experiment go on this website: http://www.sciencebob.com/experiments/straw_hoop_plane.php

    The second one is called “Rolling a can with static energy”. To make this I will need:
    * An empty soda can
    * Blown-up balloon
    * A head of hair

    I looked on another website with my brother because he knew what we had at home. I was interested in an experiment called “Invisible Ink with lime juice”. I tried it at home. Here is what you need and the steps.

    What you need:
    -half a lime
    -spoon
    -bowl
    -piece of white paper (thin)
    -water
    -cotton bud/ Ear bud
    -lamp or other light bulb ( but for me it did not work so I used matches because then it would show and it would be hotter)
    – An adult for safety

    Steps:

    1. Squeeze some lemon into the bowl and add a few drops of water.
    2. Mix the water and lime juice with the spoon.
    3. Dip the cotton bud into the mixture and write a message onto the white paper.
    4. Wait for the juice to dry so it becomes completely invisible.
    5. When you are ready to read your secret message or show it to someone else, heat the paper by holding it close to a light bulb.
    Thats all

    Here is the website that I got my experiment from:
    http://www.sciencekids.co.nz/experiments.html

    I looked through both the websites that Mr. Sam provided us and I really liked two experiments.

    1. Incredible Glide Hooper
    This experiment looks interesting to me because it looks really cool and it looks like something interesting to try making. To make this experiment happen we need:
    •A regular plastic drinking straw
    •3 X 5 inch index card or stiff paper
    •Tape
    •Scissors
    At the end of this experiment my aim is to have two circles and then a straw in the middle just like it was on the picture on the website.

    2. Roll a Can with Static Electricity
    This experiment also stood out to me and I really wanted to try doing this experiment too. But first of all to make this expirement happen we will need:
    * An empty soda can
    * blown-up balloon
    * A head of hair
    If I rub a ballon fast on my head and then but a can on the floor or on a smooth table then put the ballon close to it but it can’t touch it. Then the can will start moving towards the ballon. Isn’t that cool!
    I am really looking forward to making these experiments happen:)

    I founded a interesting site where there are a lot of experiments to do and this one you can boil a cold water into the freash water.

    Cold boiling water?
    Fill a glass three-quarters full with water. Place a handkerchief over the top of the glass and hold it on with a rubber band placed around the rim of the glass. Push down on the centre of the handkerchief until it touches the water (the experiment works best if the handkerchief is slightly wet). Keep your fingers pressed on the handkerchief and turn the glass upside down.
    The water will stay in the glass. Now, pull the handkerchief tight, so that the concave shape disappears. What happens? Why? Is it really “boiling”?

    I did a experiment which is called secret bells.
    These were what i needed to do the experiment-
    Scissors(i used the plastic one)
    String
    Wire hanger
    Table (or a wall, or a door)
    Metal spoon

    What i had to do is that with a scissors, cut a piece of string about 3 feet long and then i had to hold the two ends of the string in one hand and then the string will make a loop.Next we have to lay the loop on the top of the hanger. Push the two ends through the loop, and pull them all the way through the other side.Wrap the ends on your finger 3 or 2 times and then swing the hanger onto the door very gently and the sound will sound very soft.Now put your hands over the openings of your ears. (Don’t put your fingers in your ears!) Hold your hands tight to the sides of your head. Lean over and gently bump the hanger again.It will sound like chimes but i used a plastic hanger a loud sound came.

    i think that chicken sounds from a cup looks interesting to me because when I saw it I only need things like water, nail, a paper clip and some yarn. I don’t know if I have yarn at my house, or I can get some at the resource room

    I got some other silly obvious experiments like coke with mentos, but I think coke’s Co2 will be gone, so I am going to get some more

    Also I am interested in Magic Ketchup. But I don’t know what Kosher salt is!!!

    My second experiment is called “Floating Egg”. I tried it at home and it is very fun to do. This is the instructions:

    What you need:

    -One egg
    -Water
    -Salt
    -A tall drinking glass

    Steps:

    1.Pour water into the glass until it is about half full.
    2.Stir in lots of salt (about 6 tablespoons).
    3.Carefully pour in plain water until the glass is nearly full (be careful to not disturb or mix the salty water with the plain water).
    4.Gently lower the egg into the water and watch what happens.

    What I did also I took another egg and just put it in the water to see the differences.

    P.S It does not involve anything dangerous but it can involve messiness.

    I’ll just keep my old experiment, and I did a new experiment called “the magic ketchup experiment” I searched with science bob.

    What you need:
    -1 Litter plastic bottle
    -ketchup pack from Mac Donalds
    -salt

    Steps:
    1.Remove any labels from the bottle and fill it all the way to the top with water.

    2.Add a ketchup pack to the bottle.

    3.If the ketchup floats, go to number 4. If the ketchup sinks in the bottle, go to number 5.

    4.For the floating ketchup pack screw the cap on the bottle and squeeze the sides of the bottle. The ketchup will sinks when you squeeze it, and floats when you release it. If it does not sink when you squeeze it, try a different kind of ketchup pack.

    5.If the ketchup pack sinks, add about 3 tablespoons (45 ml) of salt to the bottle. Cap it and shake it up until the salt dissolves.

    6.Continue adding salt, a few tablespoons at a time until the ketchup is just barely floating to the top of the bottle.

    7. When it is floating, make sure the bottle is filled to the top with water, and then cap it tightly.

    8.Now squeeze the bottle. The ketchup will sink when you squeeze the bottle and float up when you release it.

    That’s it!

    I copied from the science bob and edited :> 🙂

    I made 2 experiments but now it’s too late so I guess Ill have to do the comment tomorrow. 😦

    I made 2 experiments one was the lunch bag explosion and the other one was the chicken noises. Firstly I made the lunch bag explosion. I did it twice. My first one was all good until I realized My baking soda was 2 and a half months old so it didn’t have much power in it but, I still did it and it was a fail it was supposed to inflate the zip lock bag and it did but not much and it was taking 15 minuets long. So I decided Ill do it again but this time with not baking soda but some thing like that and very powerful I put a bit hotter then what it was supposed to be and it almost worked it inflated almost till it burst but the wind pushed it down a couple of times 10 minuets later we were all so impatient that I had to go the and stomp on the fully inflated bag Boom! I shouted and everyone got so scared they jumped up. Then I stomped on it for real Boom! Boom! it burst hard and my house was screaming everything came out of the bag from the side opposite the zip lock. Then I did my other experiment where I realized I didn’t have any soft plastic cups so I used the water cups people use and you can buy in 7 11 because I couldn’t the other cups any where. so I did the experiment with both and it worked but it didn’t vibrate enough probably because they were harder.
