Convection: 200mL beaker, water, Tweezers, a crystal of potassium permanganate, a drinking straw, Bunsen Burner, heat mat, tripod and gauze mat.
Method:
1.) Set up a Bunsen burner on a heatproof mat. Put the gauze mat on the tripod but leave it just to one side of the Bunsen burner
2.) Fill a 200mL beaker with 150mL cold water.
3.) Place the beaker on the top of the tripod and gauze and allow it to settle for a few minutes.
4.) Carefully insert a drinking straw down one side of the beaker, ensuring the straw is touching the bottom of the beaker. Be careful as you do not want to disturb the water too much.
5.) Using tweezers, drop a crystal of potassium permanganate down the inside of the straw. Wait for the crystal to settle on the bottom of the beaker.
6.) Very gently, so to not disturb the water, remove the straw.
7.) Light the Bunsen and slide it under the tripod so that you are only heating the outside of the beaker where the crystal is. Observe.
Observations:
We insert the straw carefully in the side of the beaker then we drop the potassium permanganate down the inside the straw.
Explanation:
As the potassium permanganate was heated it raised. When the particle is heated more it tends to move around more.
Very nice blog post here Alliah. I love seeing pictures so keep adding those in! Your explanation is correct and i really like you use of the word particle in it. Maybe talk a bit more about what you actually saw in your observations next time :)
