When you mix baking soda and vinegar it produces gas and feels cold to the touch because it is stealing your heat. Is this an example of an exothermic or endothermic chemical reaction?
Endothermic.
A roller coaster halfway down a ramp has what type of potential energy?
High low/medium/non/ etc...
Some potential energy.
Some/high kinetic energy.
Batteries when used can be said to have this type of energy.
Chemical energy.
Diagram primary succession. 1 minute.
Pioneer species and then larger organisms may move in.
Draw a picture of a polar bear playing volleyball against a giraffe and the polar bear is losing.

Double points!!
Diagram and label the energy transformation from a house outlet to a micro-wave oven.
You may need to explain it.
*Triple points if you noticed that micro-waves are also radiant energy.*
Complete the punnet square for the genotype of parents with the following alleles:
Rr and Rr
Should be RR, Rr, Rr, rr.
Double points!!
Rock paper scissors.
Pink vs Blue (send one person up each)
Green Vs orange (send one person up each)
Winner vs winner, loser vs loser
The overall winner (W,W) gets 1000 points and takes all points from the losing time (L, L) and from the last team they beat (W, L).
List at least four evidences for chemical changes.
Precipitate is produced, unexpected color change, bubbling/gas, exothermic or endothermic, unexpected crackling sound, gas is produced, unexpected light, it can't be undone.
Triple points!!!
Batteries at rest and unused store potential energy in this specific form.
Chemical potential energy.
TRIPLE POINTS!
Hydroelectric plants make energy through the use of water. Water flows through a turbine and spins, the energy is stored in a generator. What type of energy transformation occurs by the spinning of the turbine?
Mechanical energy
What is weathering?
The fluctuation of cold and warm temperatures make rocks expand and contract and break up slowly.
Push up contest. You have 30 seconds to do 60 push ups as a group. Go.
If you did not do 60 push ups you lose 500 points.
