What's the purpose?<br />Newspaper reports<br />Information reports (living and non living)<br />Science<br />What do they have in common?<br />
Today’s Purpose<br />Science<br />You will have 15 mins at each station to conduct the experiment and report your findings using the template provided.<br />Work with the people in your reading group.<br />We will then clean up and each student can select their favourite experiment to write up as a report.<br />
How do I write a report?<br />Title: Name of Science Experiment <br />Introduction/Purpose<br />Today we are going to test ........<br />Materials<br />List everything needed to complete your experiment<br />Method<br />Describe the steps you completed during your investigation<br />Results and diagrams<br />What were the findings of your experiment.<br />Conclusion: Sum up what happened<br />
Making Goo<br />What you need:<br />1 cup cornflour<br />bowl<br />ABOUT 1/2 cup water<br />spoon<br />pie plate<br />food colouring<br />Directions:<br />Empty 1 cup of cornstarch into a large bowl. <br />Stir while you add water SLOWLY -- don't add all of it if you don't need to. <br />You need the consistency of thick pancake batter. <br />It's better to add too little water than too much. <br />Take your time! <br />Add a few drops of food colouring. <br />Stick your hands in the mixture. <br />Record what it feels like. <br />What happens when you try to roll some into a ball and then leave it alone? <br />Pour the water into a pie plate. (water is a liquid) <br />smack it with your hand<br />record what happens <br />Empty the paper plate. Pour the cornflour mixture into a paper plate. <br />smack it with your hand<br />record what happens<br />does it act differently than the water?<br />
What happened?<br />What Happened when we made Goo<br />When we talk about "states" of matter, we usually talk about the three types: solid (like a rock), liquid (like water) and gas (like the air we breath).<br />A mixture of cornflour and water make what is known as a suspension. When you squeeze a Cornflour Suspension it really feels like a solid because its molecules line up. But it looks like a liquid and acts like a liquid when no one is pressing on it because the molecules relax. This is another state of matter, called a suspension (It can act like a liquid, or, when pressed like a solid.). <br />
Magic Potion<br />What you need:<br />bowl <br />2 Tbsp vinegar<br />1 Tbsp baking soda<br />Directions:<br />Put 2 Tbsp vinegar in the bowl <br />Add 1 Tbsp baking soda (all at once) <br />Record what happens using your report template<br />NOW TRY THIS:<br />Pour 4 Tbsp vinegar in a container with an opening small enough to fit a balloon around (small vinegar bottle or juice bottles work well). <br />Pour 2 Tbsp baking soda in a balloon that isn't blown up (make a siphon out of cone of paper)<br />Without tipping the baking soda in, put the balloon over the top of the container. Use your hand or a rubber band to hold the seal.<br />Jiggle the balloon so the baking soda is dumped in.<br />The balloon will blow itself up! (this is the carbon dioxide gas) <br />
What happened?<br />What Happened when we made Magic Potion<br />The bubbles that form are carbon dioxide gas. A chemical reaction occurs between the vinegar (an acid) and the baking soda (a base).<br />For all of you bakers out there, this is also what makes cakes and quick breads (the no yeast kind) get nice and fluffy.<br />The balloon blew up by itself! <br /> (carbon dioxide gas produced during the experiment.).<br />
