Root Digging

My frist time on a root dig with the whole wellpinit school. It was hot, but was definately fun. Some of the tribal members were there to talk to us about the history of the bitter root (camas), there were lots of tools that they showed us to used to dig out the camas. We were split into different groups and we each had a chance to dig a couple of them. The tribal elders said that if it was your first time to dig a root for every year you should take your camas to them and they will bless the camas as part a cerimonial ritual that they do every year they come out to dig. They dig the camas every year because this is also one of their traditional food that they cook for get togethers or any other occasion. It's kind of sweet like a carrot, but it looks like a baby potatoe. I tried it for my frist time and it was amazing, can't wait til I get to try it cook with different ingredients to make it taste even better. We had lunch down by a lake and had barbeque salmon, hotdogs and hamburgers with lots of others snacks like chips, salad, lemonade and it was a big get-together with almost everyone on wellpinit. An amazing outing i'll miss!

Here are the materials used to create homemade Biodiesel: Vegetable Oil, Clear Jar (after mixing), Clean jar (for mixing), Methanol and Lye

Caution: Making your own biodiesel can be a dangerous process; please, be extremely careful and wear safety glasses or goggles, a face mask and heavy-duty gloves and don't forget you need adult supervision at all times...

These here is the clear jar we used to shake the chemicals for about 30 min. max. Veronica and I both took turns shaking this jar in a fresh aired room to keep the reaction on our example working.

3 Laws of motion: Tomo Racer catapult!?

3 Laws of motion: Tomo Racer Catapult
1. An object at rest remains at rest and an object in motion maintain its velocity unless it experiences an unbalanced force.
2. The unbalanced force acting on an object equals the object’s mass times its acceleration.
3. The acceleration of an object is proportional to the net force on the object and inversely proportional to the object’s mass.

Law of motion 1:
Our catapult remains at rest when we aren’t using it but when we launch something in the air this object flies into the air but it keeps its velocity until it lands.
Law of motion 2: -------------------------------------------------------------------------------

Law of motion 3:
When we pull back the launcher it tells us that we are about to release something, when we let go of the launcher the reaction is that an object flies out of the launcher.
