When we started our science unit, we had to have a question to make an independent investigation. We had a question, a hypothesis, then we had to start. We got our materials and put together our experiment. We have to get our data every day to know what was happening. To answer the question is to find out what happens to the experiment. Our experiment is about plants growing from seeds. Some seeds will be in soil and the other will be in sand. We decided to give the plants only 30 ml of water each day. Then we will see which one will grow taller or if it will grow at all. One pot has sand in it. Another pot has soil in it. The sand’s plants grew to 3 cm in four days. The soil’s plant grew 4 cm in four days. Then the sand’s plants grew more plants and grew a little taller. We will keep on doing this until the week ends. We are writing down the observations every day. Our observations so far is that the sand is growing taller than the soil. So I think that the sand’s cup will produce the tomatoes faster than the soil.
1: Get tomato seeds and put it in cups.
2: Put sand in one cup and put soil in another cup.
3; Punch holes in the bottom of the cup so when you water it, the water drains.
4: Water 30 ml of water everyday.
5: Observe your plants everyday.
We have to do this for 8 days. A safety rule for your plant is to keep the birds away from the plants because they like to try and eat the tomato seeds. You can choose or adjust how much water to put. But you have to do it daily and at the same time every day. A way to protect the plants from the birds is to cover it with a clear cover then tape it. Make sure to leave a hole so that way you can water the plants. Make sure the hole is not too big because the birds might be able to stick their beaks in. Your plants have to be also in a good climate. It’s best if you put it outside in the balcony. Our hypothesis is that the seeds in soil will grow because most plants usually grow on soil like in a garden.
